May has been a cold and wet and many farmers are struggling to get crops planted. Some for the first time. Others are already replanting. Although a week old, May 18th USDA's crop progress report is probably fairly accurate with the recent rains. Estimates are that only 34% of corn acres are planted in Ohio, with 22% of corn emerged. Emerged acres are probably higher by now. Corn planting progress was behind the 5-year average (48%), but corn emergence was slightly ahead (20%) as of May 18th. For soybeans, 40% of soybean acre were planted and 24% of soybeans emerged. On corn, some farmers got a few acres planted in late April when the air temperatures for a short period of time were warmer. but soil temps were cool. That corn either emerged, rotted or the soil got hard and struggled to emerge. Corn needs to come up within 3 days of each other for optimal yield. Cold wet weather causes many mineral deficiencies since the microbes in the soil are not warmed up and repopulating. Yello...

Farmers are again struggling this spring to get crops planted. Depending upon the amount and distribution of rain, some farmers may be almost done while other farmers are struggling to get their first field planted. In late April, there was a nice warm stretch of weather for a few days with some relatively dry weather. Some farmers got a lot planted. Others waited. Some fields of corn and soybeans are up but with the cool weather, some are struggling to grow. For slugs; cool, wet weather with slow growing crops are the best conditions for a “ slug fest smorgasbord"! Slugs like wet cool conditions and they love to eat plants under stress. Most plants, especially corn, can out grow slug damage with good weather. Soybeans are the most susceptible to slug damage. Once you see slugs starting to eat newly emerging soybeans, it is too late because once the cotyledon ( first new emerging leaves from the seed) is damaged, the plant dies. A lot of fields have either weeds still growing or...

Brian Doughtery, a Understanding Ag consultant, says compaction is a sign of a poorly functioning soil. Soil compaction is not a natural occurrence, it comes from too much equipment (heavy axle loads, too much tillage), not enough biology (lack of roots and living organisms), and excess nutrients. Well aggregated soils look like black cottage cheese; soil crumbles easily in your hand and water and gases move freely in soil. Well aggregated soils have 50% solid materials made up of ground up rock, minerals and water with the other half being pore space by volume. Compaction just means the pore space is reduced or eliminated resulting in denser compacted soil. For good plant growth, roots need to penetrate the soil to get water and nutrients and have adequate gas exchange. Roots need oxygen produced and released by the leaves to move down into the soil to break down the food produced by the leaves. Roots give off carbon dioxide after the oxygen breaks down the food in the roots. It’s a...

Beck’s Hybrids conducts annually extensive corn and soybean research to improve crop yields. They recently released a 256-page book on their recent results. Research is conducted throughout the USA, Midwest, and Ohio.  Over 2 decades, the yield penalty for late corn planting is less than on soybeans. The most important thing on corn is getting it planted at a consistent depth, spacing, population, and under the right conditions more so than actual planting date. In no-till, having good closing wheels to close the slot is essential. Optimal seed to soil contact is critical for uniform emergence and the yield benefit was 2.7 to 5%. Spiked wheels help crumble soil when conditions are not perfect.  Becks did significant corn nitrogen (N) research. Putting N fertilizer on both sides of the seed allowed more uniform root distribution and yielded an average of 7 bushels more corn. The highest average corn yield of 225 bushel per acre over 4 years was 60# N applied on both sides of th...
