Tips for Successful No-till

Image
  Diesel fuel and fertilizer prices are soaring motivating farmers to look for ways to reduce costs. This past year, many Midwest farmers started no-tilling to reduce fuel costs. With healthier soils, fertilizer costs should decrease. Healthy soils promote higher microbial levels. Each soil microbe is a soluble bag of fertilizer and your nutrient use efficiency improves, so less commercial fertilizer is needed. The soil has a huge bank of tied up plant nutrients just waiting for healthy soil microbial populations to release them to plant roots. Starting no-till is the first step. Soil compaction is usually a big problem. Excess tillage and a lack of roots in the soil profile causes soil to lack the soil organic matter (SOM) to form healthy soil macro-aggregates. The roots form macro-aggregates with the help of soil microbes. The macro-aggregates store active carbon (glues for good soil structure), improve water infiltration, increase water storage. Micro-aggregates allow good gas e...

Rain Impact on Crops and Disease

Image
  Rain this past week caused some flooding, especially in the several counties around Lima, Ohio and further south and west. Rainfall amounts of 9-10 inches were recorded. Most of Northwest Ohio got several rainfall events over several days. Officially, the 5-year drought appears to be over. Flooding effects on corn and soybean development varies and depends on crop stage of development, soil types, and how long water remains in the field. For the State of Ohio, if the corn was planted early and the corn is more mature (dough to dented), the flooding effects may be less severe; unless the corn stands in water for extended period of time (past 2 days). For northwest Ohio, delayed spring planting delayed corn growth development. Corn has caught up somewhat but a lot of corn is just past the tasseling stage and is setting kernels. This can be a tough stage for corn development if fields remain flooded for extended periods of time. Some corn fields may have had high winds, lodging and ...

Crop Development and Yield

Image
  Farmers in the Eastern Midwest are wet while farmers in the Western half of the Midwest are struggling with heat and drought. After 5 years of hot dry summers, especially in July and August; farmers in the Eastern half of the country are getting a cool summer and plenty of rain. Crop scouts are now touring the country to determine corn and soybean yields. The eastern half has to scout a flooded area with record rainfall amounts, downed corn, and standing water from central Illinois into eastern Ohio. The western half scouts crops that have had very little moisture for most of the summer. The result is thinner cobs, lighter ears, and some yellow corn from denitrification (lack of N) in the east. The USDA national estimate for corn yield is 180.7 bushels average per acre across the nation. That is down 2.3 bushel from July and 5.8 bushel from last year’s record. About 61% of the corn is rated good to excellent, down 11 points from last year. Another 14% is rated poor to very poor. ...

Biochar Soil Benefits

Image
  Biochar is a fine-grained, porous, charcoal-like substance produced by heating organic plant or animal matter (biomass) in a zero- or low-oxygen env ironment. This chemical decomposition process is called pyrolysis. Unlike regular charcoal, which is primarily produced to be burned as fuel; biochar is created for agricultural enhancement and long-term carbon storage. Biochar is made from wood chips, crop residues (like corn cobs), forestry waste, and animal manure. The biomass is sealed inside a container and heated to high temperatures, usually between 750°F and 1300°F. Because oxygen is absent, the material cannot catch fire or turn to ash. Instead, it breaks down into energy-rich gases and a highly stable, solid carbon structure. Biochar is great for enhancing soil. The microscopic, sponge-like structure of biochar acts as a physical filter that catches and holds moisture in the soil. For nutrient storage, biochar prevents fertilizer runoff by trapping essential minerals and ma...
