Farmland Leasing Meeting Set for August 5 in Tipton


Iowa State University Extension and Outreach in Cedar County is hosting a farmland leasing meeting on Wednesday, August 5, at 1:00 pm to address questions that land owners, tenants, or other interested individuals have about farmland leasing.

 

The meeting will be held at the Cedar County Extension Office, 107 Cedar Street. The meeting is approximately 2 ½ hours in length. Similar meetings are being held across Iowa during the month of August.


Attendees will gain understanding of current cash rental rate surveys and factors driving next year's rents such as market trends and input costs. Estimating a cash rental rate is a constant of the farm leasing arrangements meeting. This year's decreased profitability will require landlords and tenants to look closely at 2016 production cost estimates. Attendees will learn about types of leases and results of farmland value surveys. A 100-page workbook will be included with registration that includes land leasing information such as surveys, sample written lease agreement and termination forms, and many other publications.


"Due to changes in commodity markets, cash rent values, land values, and government programs, farmland owners and tenants may have more decisions over the next year than in previous years.  This meeting provides information to stay up to date on farmland lease issues." says Ryan Drollette, ISU Extension and Outreach Farm and Ag Business Management Specialist. Drollette will be the presenter at the meeting.


Registration is $25 per individual and $40 per couple. An additional $5 fee will be added if registering fewer than two calendar days before the workshop. Pre-register by calling the Cedar County Extension and Outreach office at 563-886-6157.

Emerald Ash Borer Confirmed in Scott and Davis Counties, Iowa

Emerald Ash Borer has been positively identified in Davenport and central rural Davis County, bringing the total of confirmed counties to 24 since it was first detected in Iowa back in 2010. This metallic green insect, which only measures about half-inch long and an eighth-inch wide, kills all ash tree species and is considered to be one of the most destructive tree pests ever seen in North America.

"With emerald ash borer already being in the area on the Illinois side, it was only a matter of time until it was found in Davenport." said Mike Kintner, Iowa Department of Agriculture and Land Stewardship EAB and gypsy moth coordinator. "With these two newest findings being nearly 100 miles apart, it is a good reminder that we just never know where or when this ash-killing insect is going to reveal itself."   

The City of Davenport's Forestry Division has been planning for the arrival of this exotic pest and has a working Emerald Ash Borer Response Plan in place. The city plans to remove ash trees infested with EAB on public properties and continue to reduce its ash tree populations in public areas. The Davis County find was in a rural area north of Bloomfield, Iowa.

Out of the 24 Iowa counties that have confirmed EAB findings, six have been found this year alone. A statewide quarantine, issued in February 2014, remains in place, restricting the movement of hardwood firewood, ash logs, wood chips and ash tree nursery stock out of Iowa into non-quarantined areas of other states.

"We still strongly urge Iowans to not move firewood long distances," said State Entomologist Robin Pruisner of the Iowa Department of Agriculture and Land Stewardship. "A large portion of Iowa is not showing signs of EAB infestation; let's keep those areas EAB-free as long as possible by not moving wood that potentially harbors EAB or other tree pests. Be vigilant and report suspicious symptoms in counties that are not yet known to be infested to a member of the Iowa EAB Team."

The Iowa EAB Team provides EAB diagnostic assistance to landowners and includes officials from Iowa Department of Agriculture and Land Stewardship, Iowa State University Extension and Outreach, the Iowa Department of Natural Resources, USDA Animal Plant Health Inspection Service and the USDA Forest Service. 

The Iowa EAB Team strongly cautions Iowans not to transport firewood across county or state lines, since the movement of firewood throughout Iowa or to other states poses the greatest threat to quickly spread EAB and other plant pests. Most EAB infestations in the United States have been started by people unknowingly moving infested firewood, nursery plants or sawmill logs. The adult beetle also can fly short distances, approximately 2 to 5 miles.

At this calendar date, the treatment window for soil-applied preventive treatment measures (soil injection, or soil drench, or granular application) has ended. Basal trunk sprays with dinotefuran can be applied until mid-June and are most effective for trees less than 18" dbh - the diameter of the tree's trunk at breast height, 4 ½ feet above the ground. Trunk injection remains a viable EAB management option, as this method can be done when the tree has a full canopy of leaves (now through August), provided there is good ground moisture. If a landowner is interested in protecting a valuable and healthy ash tree within 15 miles of a known infestation, he or she should have landscape and tree service companies bid on work, review the bids, and treat during the recommended treatment time.

Please contact Iowa EAB Team members to have suspicious looking trees checked in counties not currently known to be infested. The State of Iowa will continue to track the movement of EAB on a county-by-county basis. Before a county can be officially recognized as infested, proof of a reproducing population is needed and an EAB must be collected and verified by USDA entomologists.

ISU Extension Short Course will Increase Grazing Knowledge and Skills

Livestock producers with an interest in beginning or transitioning grazing practices can sharpen their skills by attending Greenhorn Grazing workshops offered by Iowa State University Extension. The Greenhorn Grazing short course consists of five different modules taught over the grazing season.

"Greenhorn Grazing is designed for graziers interested in a more controlled or management- intensive grazing system," said Denise Schwab, ISU Extension livestock specialist. "Producers who want to optimize forage and livestock production, increase market access and conserve natural resources will find the modules very informative."

The course will cover concepts relevant to all producers of grass-based livestock, whether it is beef, dairy, sheep or other animals, according to Schwab. Greenhorn Grazing will be held around the Maquoketa area, but is designed for any producers in eastern Iowa. Each workshop will have a classroom component with experienced instructors and a hands-on field component.

The workshops will begin promptly at 1:00 p.m. and will last through late afternoon. The sessions are scheduled for June 8, July 6, August 4, August 30 and early November.

"Workshop topics covered by the instructors and during the associated field experiences will teach producers how to improve the productivity and use of their land," said Schwab. "Training such as this removes some of the perceived barriers associated with entry into the grass-based livestock industry and supports perennial grassland agriculture."

Cost of the short course is being largely offset by grants from the Leopold Center for Sustainable Agriculture, and the Iowa Beef Center. The course fee is $75; participants are urged to attend all sessions, but fees for individual sessions are available. Fees include a resource notebook, speakers, and refreshments.

For more information on specific locations or to register, contact the Benton County Extension Office, at 319-472-4739. For more details contact Denise Schwab at (319) 721-9624 or dschwab@iastate.edu.

Updated Prairie Restoration Handbook Now Available

AMES, Iowa?A handbook for establishing and managing prairies on farmland, Incorporating Prairies into Multifunctional Landscapes (PMR 1007), has gone into its second printing, and the updated version is now available from the Iowa State University Extension  online Store.

Meghann Jarchow and Matt Liebman from the ISU Department of Agronomy developed the original publication in August 2010 and updated it for a second printing in February 2011. They conduct research on multi-year cropping systems as part of a team supported by the Leopold Center for Sustainable Agriculture's Ecology Initiative.

Less than 0.1 percent of Iowa's tallgrass prairies remain, largely because their rich soil makes the land desirable for agriculture. Yet prairies can reduce soil erosion and water pollution, provide wildlife habitat and mitigate flood events. The full-color, illustrated publication explains how farmers and landowners might incorporate prairies into their land to restore ecosystem services and potentially gain economic benefits from livestock grazing, hay production and carbon sequestration. "I have been delighted to hear how broadly the publication has been distributed and how well it has been received," Jarchow said. "I hoped that the publication could be useful to a wide range of audiences, and I have received positive feedback from numerous individuals including farmers, conservation organization workers, and university extension personnel."

At least 1,300 copies have been distributed to organizations in several states, such as Practical Farmers of Iowa, the Iowa Department of Natural Resources and the South Dakota Game, Fish and Parks Service. The content has been used in ISU classes and also will be part of an Iowa State University Extension program called "Homegrown Lifestyle," a 12-week course for people living on small acreages.

The updated version, which includes a new resource for Midwest prairie restoration, can be downloaded or print copies requested at no charge at http://www.extension.iastate.edu/store/.  The Leopold Center for Sustainable Agriculture, North Central Sustainable Agriculture Research & Education (SARE) and Iowa State University Extension sponsored the printing.

Yard and Garden: Rhubarb

Although it is classed as a vegetable, rhubarb is used as a fruit because its high acidity gives it a tart flavor. Iowa State University Extension horticulture specialists answer gardeners' questions about growing and using rhubarb. Whether questions come from gardeners planting their first rhubarb patch or maintaining an established planting, extension specialists answer questions using the most current research. Gardeners with additional questions can contact the experts by emailing or calling the ISU Extension horticulture  hotline at hortline@iastate.edu or 515-294-3108.

What would be a good planting site for rhubarb?

Rhubarb performs best in well-drained, fertile soils that are high in organic matter. Heavy, clay soils often can be improved by incorporating organic matter, such as compost or well-rotted manure, into the upper 12 to 15 inches of soil. The planting site should also receive at least six to eight hours of direct sun each day. Avoid shady sites near trees and shrubs.

When can I start harvesting my newly planted rhubarb?

After planting rhubarb, it's best to wait two years (growing seasons) before harvesting any stalks. The two-year establishment period allows the plants to become strong and productive.

Rhubarb can be harvested over a four-week period in the third year. In the fourth and succeeding years, stalks can be harvested for eight to 10 weeks.

What is the correct way to harvest rhubarb?

Harvest rhubarb when the stalks are 10 to 15 inches long. Grasp the stalk near its base and pull up and slightly to one side. Immediately after harvesting the rhubarb, remove the leaf blades from the stalks with a sharp knife. Discard the foliage. The stalks can be placed in a plastic bag and stored in the refrigerator for two to four weeks.

When harvesting rhubarb, do not remove more than two-thirds of the fully developed stalks from any plant at any one time.

Are rhubarb leaves safe to put in the compost pile?

Although rhubarb leaves do contain poisonous oxalic acid, they can be placed in the compost pile. Oxalic acid, like other organic acids, is not readily absorbed by plant roots. Compost containing decomposed rhubarb leaves can be safely applied to the vegetable garden.

When should I stop harvesting rhubarb?

Gardeners should stop harvesting well established rhubarb plants in mid-June in Iowa. Continued harvest through the summer months weakens the rhubarb plants and reduces the yield and quality of next year's crop.  If the rhubarb plants are vigorous, pulling a few stalks and preparing a dish for a special occasion in summer shouldn't be a problem. Harvesting rhubarb in summer should be a one time event, not a frequent practice. Continued harvest through the summer months weakens the rhubarb plants and reduces the yield and quality of next year's crop. In general, it's best to stop harvesting rhubarb in mid-June in Iowa.

There is an erroneous belief that rhubarb stalks are poisonous in summer. The stalks will likely be a little tougher than those harvested in spring, but they are not poisonous. Plant vigor is the reason that rhubarb should not be harvested in summer.

Flower development is natural for rhubarb and most other plants. Drought, extreme heat and infertile soils may encourage flowering. Age is another factor. Old plants tend to flower more than young ones.

Regardless of the reason, flower stalks should be promptly pulled and discarded. Plants will be less productive if allowed to flower and set seeds.

Flower formation can be discouraged with good cultural practices. Water rhubarb plants every seven to 10 days during dry weather. Sprinkle ½ cup of an all-purpose garden fertilizer, such as 10-10-10, around each plant in early spring. Control weeds by shallow hoeing, hand pulling or mulching.

Plan Ahead to Reduce the Impact of Natural Disasters

AMES, Iowa - Before natural disasters strike, families should develop emergency plans and create emergency supply kits. This message is one Iowa State University Extension hopes Iowans will take seriously. Planning before the storm clouds gather and rivers rise will save lives, fear and panic. "Create plans, write them down and share them with friends or family," said Linda Fischer, ISU Extension regional director. "Be sure to talk with children about emergency plans." Fischer is a member of the Iowa State disaster planning team and works in conjunction with the Red Cross, Federal Emergency Management Association (FEMA) and the Extension Disaster Education Network (EDEN) to build awareness of steps for natural disaster preparedness. The team is making several publications available that outline how people living in areas prone to tornadoes and floods can create an emergency plan and pack emergency supply kits.

"Iowans depend on their county extension office for answers after storms and floods hit; we want them to also think of extension as a resource for emergency preparedness," Fischer said.

Tornado preparedness

Fischer said to start by designating safe areas to survive a tornado. "Determine the best place to seek shelter from an impending tornado in your home and workplace," she said. "Be aware of designated tornado shelters in public buildings and private businesses. Use this information to create a plan, and if you have children, practice the plan. Be sure to take time to think about where you can find shelter if you are in a vehicle or outside."

Know where to seek shelter in your home:

  • Go to lowest level available (basement or cellar).
  • Find an inside room with no windows and strong walls.
  • If the room has windows, keep them closed.
  • If in a mobile home, get out and go to the nearest sturdy building.
  • Get under a piece of sturdy furniture, such as a workbench, or heavy table or desk, and hold on to it.
  • Use your arms to protect your head and neck, or use a heavy blanket or pillow to help protect you and to cover
  • your head.


"If you are in a vehicle or outside, never try to outdrive a tornado because it can change direction quickly and lift and toss your vehicle through the air," Fischer said. "Leave the car immediately and take shelter in a nearby building. If there is no building, lie flat in a ditch or depressed area, cover your head and watch for flooding."

Flood preparedness

Written emergency plans are also recommended for families, schools and workplaces in areas with the potential for flooding. Practice your plan, and share it with others. Plans that include home evacuation during the flood should include the following:

  • Take your disaster supply kits with you when evacuating.
  • Turn off utilities, and do not touch electrical equipment if you are wet or in standing water.
  • Avoid walking through moving water.
  • Avoid driving into flooded areas.
  • Be cautious since floodwaters may be contaminated.
  • Create a Disaster Supply Kit


"Build disaster supply kits for all family members and pets for at least three days," Fischer said. "Make the kits so they
can be scaled down in case of evacuation. Preparing a kit for each child will add comfort and reassurance in a time of
stress and anxiety."

Basic kits should include :

  • Food and water
  • Medicines, copies of prescriptions, personal hygiene items, first aid supplies
  • Important documents, personal identification, copies of insurance
  • Cash or travelers checks
  • Other essential supplies that your family may need: flashlights, extra batteries, blankets, seasonal clothing, a
  • battery-operated or crank radio, a weather radio, cell phones and chargers
  • Additional items to include in a child's kit include : books and games, extra clothes and shoes, comfort food, whistle (to
  • blow to attract attention), paper with home address, parent's names and phone numbers, other emergency contact numbers,
  • current photo of the child and family, tooth brush and toothpaste.


For additional planning information and general information about tornadoes, flooding, helping children prepare for
emergencies and a list of first aid supplies contact your county extension office.

Preparing Children for Child Care

Talk With Your Child about What Is Happening

New experiences can be scary. You can ease a lot of fears by talking to your children about going to child care if your children can understand. Let them know what is different about the new situation, as well as what is the same.

Share Your Positive Attitude about Child Care with Your Child

Your child will feel good about going to child care if you feel good about your decision. Talk with your child about the toys, people, and activities he or she will experience in child care. Let your child know that going to child care is necessary and can be fun.

Begin New Child Care Situations Gradually

It's frightening to be put in a new situation. Parents can help ease the transition by bringing their child to child care gradually. If it's possible, try putting your child in only part time?for a few hours or half a day?for the first few days. This will also help the child care provider get to know your child before he or she spends full days there.

Establish Good Communication with Your Child Care Provider

Leaving a child in someone else's care can be hard for parents. You may worry about your child's behavior, whether or not the provider and the other children will like your child, and if the provider can understand and fulfill your child's needs. Let your provider know as much as possible about your child.

Expect a Reasonable Amount of Adjustment Time

Every child is different. Some children will adjust to a new child care situation almost immediately. A few others will take several months. Some children will seem to adjust to the situation quickly, but then experience difficulty a few weeks or months later.

Yard and Garden: Forsythia

After a long, drab winter, most gardeners anxiously await the arrival of spring. One sure sign that spring has truly arrived is the bright yellow flowers of the forsythia. This week Iowa State University Extension garden experts have answers to questions about this deciduous shrub named after William Forsyth, an 18th century Scottish horticulturist. Gardeners with additional questions can contact the experts by emailing or calling the ISU Extension horticulture hotline at  hortline@iastate.edu or  515-294-3108.

My forsythia shrubs are vigorous and healthy, but don't bloom well. Why?

Forsythias bloom on old wood. Unfortunately, the flower buds on some varieties are not reliably cold hardy in Iowa. For example, the flower buds on 'Lynwood Gold' and 'Spring Glory' are hardy to minus 10 degrees Fahrenheit.  Since most areas in Iowa experience winter temperatures below minus 10 F, these cultivars often don't bloom well in the state.

Improper pruning is another possible cause. Flower buds on forsythias begin to develop by early summer.  Pruning the shrubs anytime from mid-summer until just prior to bloom will drastically reduce flowering. To achieve the best floral display, forsythias should be pruned immediately after flowering.

What are some good forsythia varieties for Iowa?

When selecting a forsythia, choose a cultivar that reliably blooms in Iowa. The flower buds on some varieties are not reliably cold hardy in Iowa. For example, 'Lynwood Gold' and 'Spring Glory,' typically don't bloom well in Iowa as their flower buds are often killed by cold winter temperatures.

Forsythia varieties that grow well and bloom reliably in Iowa include 'Meadowlark' (bright yellow flowers, grows 8 to 10 feet tall, has arching spreading form), 'Northern Sun' (medium yellow flowers, grows 8 to 10 feet tall, has arching spreading form, University of Minnesota introduction), 'Sunrise' (medium yellow flowers, grows 5 to 6 feet tall, dense growth habit, an Iowa State University introduction), and 'Northern Gold' (yellow gold flowers, grows 8 to 10 feet tall).

When is the best time to prune forsythias?

Since they bloom on old wood, forsythias should be pruned immediately after flowering. Pruning the shrubs anytime from mid-summer until just prior to bloom will reduce flowering in spring. When pruning mature forsythias, it's best to remove one-fourth to one-third of the oldest (largest) stems at ground level every other year. New shoots will emerge from the ground and bloom in following years. Old, neglected forsythias can be rejuvenated by pruning them back to within 3 to 4 inches of the ground in late winter or early spring.  The shrubs will grow back quickly and should begin blooming again in one or two years.

What would be a good planting site for forsythias?

Forsythias grow and bloom best in areas that receive at least six hours of direct sun. They will grow in partial shade, but won't bloom as heavily. Forsythias adapt to a wide range of soils. However, they do not perform well in wet, poorly drained sites. 

The forsythia is an excellent plant for mixed shrub borders. It can also be utilized as an informal hedge.  Low-growing cultivars can be used as groundcovers.

How do you propagate forsythias?

The forsythia is easily propagated from softwood cuttings. Softwood cuttings should be made from the current season's growth in late June or early July. Using a sharp knife, cut off 4 to 6 inch long shoots. Pinch off the leaves on the lower half of the cutting. Dip the base (cut end) of the cuttings in a root-promoting compound. Root the cuttings in a large pot or flat containing coarse sand or perlite. Insert the bottom two inches of the cuttings into the rooting medium and firm the material around the base of each cutting. After all the cuttings are inserted, water the medium and let it drain. Cover the container and cuttings with a clear plastic bag or dome to reduce water loss. Then place the cuttings in bright light, but not direct sunlight. Forsythia cuttings should root in six to eight weeks. When the cuttings have well developed root systems, remove them from the rooting medium and transplant into individual pots using a well-drained potting mix.

 

Dealing With Tree Damage

AMES, Iowa ? Stormy weather frequently damages trees throughout Iowa. In most cases, the extent of tree damage isn't due to the luck of the draw.

According to Richard Jauron, Iowa State University Extension horticulturist, certain tree species are much more susceptible to storm damage than others. For example, silver maple, Siberian elm, willow and green ash are quite vulnerable to strong winds. Oaks, lindens and sugar maples are less susceptible to storm damage. In addition to tree species, the age of the tree, its condition and maintenance history also determine the extent of storm damage. Large, old trees with a structural weakness, such as some trunk decay and those with narrow branch angles are particularly susceptible to damage. No tree species can withstand the fury of a tornado.

Assessing storm-damaged trees
Carefully examine trees to determine the extent of damage. Give immediate attention to trees that are hazards to people or property. If a power line is involved, utility company personnel are the only ones who should be working in the area. After the elimination of hazardous situations, individual tree care can be assessed.

Storm damage to a tree can vary from a few small broken limbs to complete destruction. Severe damage to the main trunk often warrants removal of the tree. Trees that have sustained major trunk damage are no longer structurally sound and may come down completely in the next storm. Trees that have the majority of their crown destroyed are probably not salvageable.

Caring for storm-damaged trees
When pruning damaged trees, use correct pruning techniques to minimize the size of the wound and avoid flush cuts. Remove stubs by pruning back to an undamaged side branch, main branch or trunk. Generally, pruning paints are not necessary. However, wounds that occur on oaks between March 1 and July 1 should be painted to reduce the potential transmission of the fungus responsible for oak wilt. When painting pruning cuts on oak trees, use a latex house paint rather than asphalt or creosote-based paints.

The pruning of large branches and damaged branches high in the tree canopy should be left to trained arborists. Cabling and bracing may be appropriate if the cost involved can be justified. Cabling and bracing do not save trees that have suffered extensive structural damage.

Tree removal and replacement
If tree removal and replacement ends up being your only alternative, Jauron recommends selecting tree species and cultivars with a sturdy reputation. Excellent maple species include black and sugar. Oak species for Iowa include white, swamp white, bur and red. Linden (both American and littleleaf), American hophornbeam and ginkgo are other possibilities. Selection of a sturdy tree species alone will not ensure a strong tree. Proper pruning when small is imperative.
