Our warm and humid Mississippi climate makes nitrogen (N) fertilizer management challenging. Let’s review the basics about N terminology as various product claims fly about with some puzzling promotional material being used. Be sure that you know what is being
The natural condition of most Mississippi soils is to become more acidic over time which reduces crop yields. From 1989 to 2009, just over half the soil samples analyzed by the MSU Extension Service Soil Testing Laboratory had pH values
The original Best Management Practice (BMP) for managing nutrients to maximize profitability and minimize potential environmental issues is soil testing. This time of year is always exciting for Mississippi farmers; we’re past the winter (maybe. . .) and tractors are
Sulfur in Mississippi Crop Production Sulfur is required in fairly large quantities by most crops. It is an essential building block in chlorophyll development and protein synthesis. Sulfur is also required by the rhizobia bacteria in legumes for nitrogen fixation.
Calcium and Magnesium For Mississippi Crops Calcium (Ca) and (Mg) magnesium are positively charged secondary nutrients. They are generally adequate in most Mississippi soils with favorable pH and organic matter levels. They affect acidity when applied to the soil, and
With the current commodity prices, some suggest that the 2011 crop be ‘insured’ by applying micronutrients. Is this good policy for Mississippi field crops? These essential elements are required by plants in very small amounts: boron, zinc, molybdenum, iron, manganese,
There are several keys to successful wheat nitrogen fertilization in Mississippi. Split application of nitrogen fertilizer is likely more important for wheat than any other crop, including corn. This is because wheat nitrogen fertilization occurs during the wettest months of the year – in a high rainfall, warm regional climate conducive to nitrogen loss.
Poultry litter has long been used to provide nutrients for pastures, hay, and other crops in the south-central Mississippi broiler production region. Volatile fertilizer prices increased interest among cotton producers in using litter as a nutrient source. Fortunately, there is
