Planting into Dry Soil

Image
  Grain harvest has started but many areas have low soil moisture. Planting grains or a cover crops into dry soil can be difficult. The crop may germinate but may not grow or survive if adequate moisture is hard to obtain. Here are some planting considerations if your soil is dry and you are trying to plant another crop. First, the goal is to conserve moisture. No-till grains like wheat or rye or even other cover crops will help conserve moisture. Tilled soils lose about .5-1.0 inch of soil water. Most wheat and cover crops need at least 35%-45% soil moisture to germinate. A worst-case scenario is if just enough moisture causes seed to germinate, but then not enough to keep it alive. If your soil is really dry, either plant before a good rain or right after one. If planting deep, a hard rain may cause the soil to crust. This would be less of an issue in no-till fields than fields that are excessively worked, where the soil is fine, which tends to crust more. Second, for wheat, plant a

New Weed Resistance

Image
  Farmer have a new type of weed resistance to worry about. Farmers have been using herbicide or chemical weed control for many years. Weeds have learned several ways to get around herbicides in order to survive. While it is recommended that farmers rotate different groups of herbicides and use full rates, sometimes that does not happen and weeds become herbicide resistant. That has been the main way weeds like pigweed, water hemp, and mares tail have become weed resistant. Some weeds have become resistant to one or several groups of herbicides and now some weeds have even learned to become resistant to almost any herbicide. That is a scary proposition! Often farmers use several passes of herbicides with different modes of action (MOA’s) to control weeds. The goal is to reduce the weed population down to zero so that no survivors pass on any genes that are resistant. The problem is that there are millions of weed seeds in an acre of land, stored over many years. So weed seed is always

Late Season Crop Diseases

Image
  Late season diseases are occurring in corn and soybeans. Tar spot in corn and sclerotia or white mold plus soybean cyst nematodes (SCN) in soybeans. In many cases, it’s too late to prevent the diseases. However, there are some management practices to reduce future incidences of the diseases. For corn tar spot, the symptoms include irregularly shaped black structures on leaves. The black structures are firm, appear mostly smooth on the surface and the spots do not rub off or break open. Tar spot can also produce black spots circled by tan lesions with dark borders. Tar spot overwinters on surface crop residue. The spores are dispersed by the wind and rain droplets splashing the inoculum onto plants. The inoculum likes cool summer conditions with adequate moisture and high humidity. The recent August rains with cooler days and nights is causing good growing conditions. Field with a history of tar spot are most susceptible. The best time to apply a fungicide is at tasseling (VT) up to t

Estimating Crop Yields

Image
  As crop start to mature, farmers are estimating crop yields. Weather conditions have been variable. Many soil are drier than normal. However, some fields have had almost perfect rains and some way too much. Expect yields to be as variable as the rainfall, even within the same field. The best way to estimate corn yield is to use the yield component method. This method was developed by the University of Illinois. The following procedure comes directly from Dr. Bob Nielson, at Purdue University. The yield component method uses four components. These yield components include number of ears per acre, number of kernel rows per ear, number of kernels per row, and weight per kernel. The first three yield components (ear number, kernel rows, kernels/row) are easily measured in the field. Final weight per kernel obviously cannot be measured until the grain is mature (kernel black layer) and a 15% grain moisture of 15% which is the typical moisture value used to determine a 56-lb market bushel.

Soil Conservationist: Hugh Bennett

Image
  Hugh Bennett was the first Soil Conservation Service (SCS) director. SCS was created by our U.S. Congress in 1934. SCS later became known as the National Resource Conservation Service (NRCS). Hugh was an outspoken proponent of stopping soil erosion. In 1934, Hugh testified before congress during the Great Depression when the Dust Bowl was at its peak. The whole country was hot and dry during the 1930’s, hotter and dryer than today. The long-extended drought of the 1930’s (11 years, 1930-1940 with 15% to 25% below average rain per year) plus the over grazing and the tillage allowed USA soil to blow away. The previous decade, a large swath of the Southwest was converted from permanent prairie with long fibrous roots to wheat which was seasonal and corn, and oats (other seasonal crops). At that time, land was grazed heavily until the soil was almost bare. Once the roots and plants were gone, the wind started blowing and it carried the soil with it. Over 350 million tons of topsoil in Ka

Planting Small Grains Tips

Image
  Local farmers had excellent wheat yields this year and with higher wheat prices, wheat can be a profitable enterprise. The war with Russia and Ukraine continues to keep wheat prices higher than normal. For crop rotation purposes, adding wheat may reduce weed populations and some diseases. If wheat is planted and harvested in a timely manner, it is possible to double crop soybeans or grow a cover crop. Farmers also have the option of baling straw as another enterprise. Wheat and other small grain crops like barley, cereal rye, oats all have some possibilities for expanding the crop rotation and giving an alternative crop to harvest. For high yields, early planting is critical to get the crop off to a good start. Winter wheat is generally planted in September and it is not recommended before the Hessian Fly free date (From September 22 in Northern Ohio to October 5th in Southern Ohio). In Ohio, best results are wheat planted within 10 days of the Hessian Fly free date for each county.

Crop Progress

Image
  As crops crop growth enters the last weeks of August, nights are getting shorter and colder. Crops are trying to fill either pods (soybeans) or kernels (corn). Time is slipping away for many crops. Some soybeans with an early start have good pods and good yield potential. Many double soybeans and those farms hit by drought do not have a lot of pods set yet. Corn may have taken the weather better than soybean this year, however; some corn ears are not fully filled out. For the last two years, hot dry weather in June has hurt crops from getting a good start. Perhaps it’s the smoke from Canadian wildfires, but many crops are at least 2 weeks behind normal development. Some farmers are hoping for a late frost this year to let those slow developing crops mature. Most famers tell me they had some of the best wheat yields ever plus high-quality grain. Wheat yields generally range from 60 to 90 bushel for my farmers. This year the range was 80 to 120 bushel. With less rainfall in spring and

Nationwide Case Study on Soil Health

Image
  A nationwide study of 30 USA farms show how improving soil health helped farmers economically while also creating resilience to adverse weather. These farms covered the USA and included both crop farms, livestock farms, orchards, grazing systems, and vineyards. The study was conducted by the Soil Health Institute (SHI), the National Association of Conservation Districts (NACD), and USDA-NRCS. This was a multi-year study looking at farms that had adopted soil health management systems (SHMS) long-term. The Midwest farms used practices like no-till and cover crops to improve soil health. Crops like corn, soybeans, wheat, and hay were primarily studied in the Midwest along with dairy, hogs, and chickens. Farmers were interviewed over several years comparing the economic costs and benefits of their system before and after adoption of conservation practices. The goal was to determine how resilient the farms were and what were the costs, risks, and overall benefits or detriments to adaptin

Transitioning to Organic Farming

Image
  Several farmers have requested information on how to transition to organic farming. Organic farms vary from a few vegetable acres to several thousand acres with or without livestock. Klass Marten is a New York organic farmer specializing in grains for milling, farming 1700 acres. Rick Clark is an Illinois/Indiana no-till, cover crop, organic farmer with 7,000 acres of corn, soybeans, wheat, and hay. Organic farming like conventional farms come in all sizes and configurations. USA organic food production is around 52 billion dollars (2021), up from 27 billion in 2010. Organic production makes up about 6% of overall USA food sales but is produced on about 1% of USA farmland. Farms transitioning to organic production increased about 17% from 2016 to 2019. USA organic food demand has increased about 8% per year with a slight decrease recently due to COVID, inflation, and economic conditions. Australia leads the world in organic production with 8.8% of its land farmed organically, account

Soybean Sudden Death Syndrome

Image
  Sudden Death Syndrome (SDS) and soybean cyst nematode (SCN) damage are often linked together. SDS is a soil borne fungal pathogen (Fusarium virguliforme) that invades the roots and lower stems of soybeans producing a toxin. SDS can devastate soybean fields causing aborted flowers and yellow dying plants. SDS has two major phases. In the first phase, it attacks the roots then in the second phase, it attacks the leaves causing leaf scorch. SDS infection occurs early in the season and then the SDS symptoms show up later in the season. SDS and SCN symptoms are more prominent in hot dry years. Foliar SDS symptoms include small to pale green leaves early on with small circular spots in the late vegetative stages to early reproductive soybean stages. The area between the leaf veins turn bright yellow then brown as the disease progresses. When the infection get severe, on roots, blue fungal masses can be seen. SDS is common on sandy soils, top of hills and knolls, but also on plants under st

Summer Cover Crops

Image
  Wheat harvest is mostly complete and many fields are being baled for straw. Some farmers have planted double crop soybeans, but with the sporadic rains, many fields are lying bare. Looking at the calendar, it’s too late to plant soybeans and bare fields just grow weeds! Another option is to plant a cover crop, depending upon your goals, and what crop will be planted next year. Cover crops planted in August have an advantage over fall planted cover crops. First, they capture more sunlight. Cover crops need at 60-90 days of growth before winter to survive. Second, if you spray the weeds first before you plant, there is less competition, so they produce better stands. Third, summer and fall rains allow cover crops to get better growth. Generally, what ever growth you get above ground is going to be matched below ground. For these reasons, planting cover crops after wheat has many advantages. To optimize cover crop growth, the best thing to do is bale the straw. It is not a deal breaker,

Payments for Regenerative Practices

Image
  Due to government subsidies, a number of companies are now paying farmers for regenerative farming practices and conservation practices that reduce greenhouse gases. Agriculture, it is estimated, may be responsible for about 10% of greenhouse gas emissions to the atmosphere. However, agriculture can be a huge sink or storage vessel for stored carbon. Currently only about 15% of farmland is considered regenerative with the goal of reaching 40% by 2030! Reaching that goal will require higher payments to farmers to make that change. Most of the money comes from the Inflation Reduction Act passed last year, around 40 billion dollars. Companies get paid for buying farm commodities that reduce our “Carbon footprint” which can amount to multi-millions of tons of carbon. Several practices are being promoted from cover crops, reduced tillage, nutrient optimization, agro-forestry practices, and grazing. Farmers will have many opportunities to participate in these government/company sponsored p

Crop Nutrient Status

Image
  A mixed bag is occurring this year. Some farmers have col, dry soil while others are getting too much rain. Variable weather conditions mean there are a variety of nutrient problems. The most common complaint seems to be slow growing soybeans. Soybeans planted into heavy cereal rye combined with cold nights is resulting in slower soybean growth, especially if it is dry (slow nutrient release). As summer progresses, temperatures should warm up the soybeans should catch up. Rye residue conserves moisture and keeps the soil in a more ideal range for optimal plant and microbial growth later in the season when temperature get hotter, high 80’s and 90’s. There are several nutrient issues farmers can scout for this year. On corn and soybeans, Boron (B) and Calcium (Ca) deficiency symptoms are noticeable. On corn, look for parallel lines or just slight zipper effects on the outside of the leaf to identify B deficiency. Boron is needed to get calcium into the plant. After nitrogen and potassi

Wildfire Smoke Impacts

Image
  The Canadian Wildfires are playing havoc on humans, livestock, and agriculture. At least 3,000 Canadian wildfires have burnt over 20 million acres with over 500 wildfires still active. The fire season in Canda runs from May to October and this is the worst fire season (Level 5) since 1989. Dry weather, drought, plus poor forestry management has led to a lot of fuel for these wildfires, resulting in smoke and air pollution for the Midwest and Northeastern USA. The hazy atmosphere is due to excess smoke and fine particulates in the atmosphere and can cause lung and breathing issues. Fine particulate matter (PM 2.5) in smoke inhaled in the lungs can lead to many health problems. Wildfire smoke symptoms include coughing, stinging eyes or eye irritation, fatigue (tiredness), headaches, rapid heartbeat, scratchy throat, short breath, runny nose, and wheezing. People with asthma and heart disease are at the most risk of having adverse reactions to the smoke and fine particulates. Humans are

Fuel Tax Credits Section 45Z

Image
  The Biden Administration passed the 2022 Inflation Reduction Act and farmers may benefit from this legislation. Under section 45Z, the legislation provides a tax credit for the domestic production of clean transportation fuels, The 45Z tax credit applies to fuels produced after Dec. 31, 2024 and sold before Dec. 31, 2027. It includes $369 billion in spending and tax credits for climate and energy programs over 10 years. Instead of paying farmers to sequester soil carbon, this legislation pays farmers to reduce their carbon foot print by using sustainable fuel or producing sustainable fuel. The legislation extends the biodiesel and alternative fuel credits through December 31, 2024. It extends the $1.00/gallon Section 40A biodiesel and renewable diesel credit and the $1.00/gallon biodiesel mixture credit, which was due to expire after 2022. Several other alcohol, biodiesel, and alternative fuel credits were renewed including a $.50 alternative fuel credit. In most cases, the tax credi

Corn Nutrient Uptake

Image
  Due to colder nigh time temperatures and a lack of moisture, most crops are running about 2-3 weeks behind their normal growth pattern. Early planted corn appears to be growing better due to deeper roots. Many soybean fields are still trying to germinate yet. As most farmers know, a little more rain could really help improve crop growth. Soils provide 13 of the 16 nutrients needed to produce grain. In addition, soil must release these nutrients quickly enough to meet daily high nutrient demands of the corn plant during the V6 to R1 growth stages. V6 refers to vegetative growth when the corn has 6 true leaves. R1 refers to the start of corn tasseling and pollination when corn is putting on grain. For corn, nutrient uptake is the greatest from about V6 to R1. During this time period, the corn is growing new plant tissue for roots, leaves, and stalks. The plant is determining corn yield by starting to grow a corn ear and it is creating pollen in the corn tassel to pollinate and fertiliz

Improving Soil Conditions

Image
  Some cooler temperatures are coming and some rain has occurred. Most farmers are hoping for more rain to get their crops out of the ground and growing. One thing, where ever the soil had higher amounts of soil organic matter (SOM), the crops emerged and are growing much better. Every 1% SOM holds about 0.5 to 0.8 inches of rain, which helps crops germinate and grow until they get their roots established. Building SOM requires getting more roots in the soil. No- till and cover crops are two ways to build SOM and reduce adverse weather. As wheat harvest approaches, farmers may be considering double cropping soybeans. In a dry year, soybeans may not be the best option, but letting wheat stubble remain bare promotes weeds. Many cover crops can grow and thrive with little soil moisture including buckwheat, cowpeas for nitrogen, and teff (forage crop). Diverse cover crop mixtures help each germinate and get needed nutrients. Planting cover crops after wheat is a safer bet when moisture is

Handling Dry Conditions

Image
  In 2023, Ohio experienced the 6th driest May since the 1930’s Dust Bowl. The combination of cool May weather and mostly dry soil conditions delayed crop germination and has reduced crop growing conditions. Crops are already struggling to grow. Several factors are contributing to this dilemma. First, the switch from a La Nina weather pattern in the Pacific Ocean to an El Nino usually means drier weather conditions in the Midwest. When La Nina’s are strong and long, you can expect a stronger El Nino pattern. El Nino’s may last 1-3 years on average. Most weather experts expected drier conditions in late summer and early fall, but dry weather came earlier than expected! Second, along with weather patterns, solar sunspot activity is at a higher intensity. Solar sunspots normally peak about every 11 years with a solar sunspot peak expected in 2025. The last few solar sunspot activity cycles have been mild to average, but the sunspot intensity is much higher this time around. There is a hig
