  1. Soil Temperatures and Accumulated GDD

    Average 2 inch soil temperatures and accumulated Growing Degrees Days (GDD) from select OARDC Weather Station locations are shown. Based on current accumulated GDD (Table 1) we would expect corn April 12 planting prior to April 30 to be emerged or emerging soon.

  2. An easy to use test can be done to predict potential soil crusting on farm fields.  All you need is some chicken wire, water, a glass jar, and a dry clump of soil.  When you immerse the clump of soil in the jar of water, the longer it holds together, the better the soil structure to resist crusting. 

    The slake test compares two chunks of topsoil in water to see how well and how long they will hold together. Here are the steps according to NRCS Newsletter article #14:

    The calendar says it’s time for spring field activity in Ohio and farmers are eager to prep fields and plant this year’s crops. However, average temperatures across Ohio have remained cooler than usual with the previous 30-day period (March 16 - April 15, 2018) running 2 to 6 degrees Fahrenheit below normal (based on 1981-2010). Combined with precipitation up to twice the normal amount in some areas, the weather is certainly not cooperating with ideas of an early jump on planting.

  4. Two-inch Bare Surface Soil Temperature-Daily Avg

    During our recent survey of CORN Newsletter users, one item suggested for addition was a chart of soil temperatures in the spring. The Ohio Agricultural Research and Development Center (OARDC) Agricultural Research Station located throughout the state have 2 and 4 inch bare surface soil temperatures monitored on an hourly basis. The chart provided here summarizes the average daily two inch bare soil temperature from several stations.

    Are you interested in learning about cover crops and soil health? If so, consider attending a Soil Health Workshop on March 28th with OSU Extension, NRCS, and Henry SWCD. Jim Hoorman and Alan Sundermier will be presenting a variety of topics including:

    Biology of Soil Compaction

    Economics of Cover Crops

    Keeping Nutrients out of Surface Water

    Managing Grasses and Brassica Cover Crops

    Managing Pests: Voles & Slugs

  6. Infiltration is the downward entry of water into the soil. Infiltration rate is expressed in inches per hour. Rainwater must first enter the soil for it to be of value. Water moves more quickly through the large pores of a sandy soil compared to slower movement through a clay soil with small pores. Infiltration is an indicator of the soil’s ability to allow water movement into and through the soil profile. Soil temporarily stores water, making it available for root uptake, plant growth and habitat for soil organisms.

    A suite of soil health measurements are becoming available which are not part of the traditional soil chemical tests. Soil aggregate stability is an important physical indicator of soil health, which protects organic matter accumulation, improves soil porosity, drainage and water availability for plants, decreases soil compaction, supports biological activity, and nutrient cycling in the soil.

  8. “Addressing Water Quality Concerns in Drainage Improvement Projects” will be the theme of the SWCS conference on Friday, January 19, 2018 from 9:00 am – 4:00 pm at the Der Dutchmen Restaurant in Plain City, Ohio. Topics include: Ditch Improvement projects panel, Using Bio-Indicators to Assess Stream Water Quality, Two-stage Ditches, Woodchip bioreactors, Phosphorus filters. The public is invited. Register by January 15. Questions call Kevin King at 567-224-9217.

    The two-day Soil Health Workshop provides farmers and landowners with an in-depth look at factors that contribute to long-term soil health. Topics discussed in the workshop include an overview of soil biology and ecology, how to select and manage cover crops for your farm, nutrient recycling and water quality, and more. The workshop combines experience and information from USDA-NRCS, the Putnam Soil and Water Conservation District, and OSU Extension. All materials, including the Cover Crops Field Guide, and lunch are included in the registration fee of $10.

     Given the warmer than normal winter and large amounts of rainfall received in areas, some livestock producers will be looking to apply manure in February when farm fields are frozen enough to support application equipment. Permitted farms are not allowed to apply manure in the winter unless it is an extreme emergency, and then movement to other suitable storage is usually the selected alternative. This article is for medium and small livestock operations.
