    With below average temperatures and snow, wheat growth and development is slower this year compared to the previous two years. Last year, wheat in Pickaway County reached Feekes 6.0 growth stage the last week of March. Remember, exact growth stages cannot be determined by just looking at the height of the crop or based on calendar dates. Correct growth identification and knowledge of factors that affect grain yield can enhance management decisions, avoiding damage to the crop and unwarranted or ineffective applications.

    The expected cold and wet weather pattern for spring that has been forecast since December continues. There will be some relief this week after a cold start to the week with temperatures 10 degrees below normal we will switch and see temperatures by the end of the week a good 10+ degrees above normal but when average out through Sunday April 15, we will return to about average temperatures for the week. Drying is expected as well through Friday with only minor precipitation events but another rain event is expected this weekend.

    Heavy farm machinery compacts the soil, both on tilled ground and no-tilled ground. Compaction induced by agricultural machinery often affects soil properties and crop production. Axle load is the first factor that has to be considered in soil compaction, according to Randall Reeder, Ohio State University Emeriti and Dr. Sjoerd Duiker, Penn State Soil Specialist. Axle load is the total load supported by one axle, usually expressed in tons or pounds.

    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.
