Abundant rainfall has soaked corn fields for extended time during April and late May, exposing nitrogen fertilizer to potential loss. This article gives guidelines for estimating potential N loss. . . . → Read More: How much Nitrogen have I Lost from Saturated Soils?
It is not just a song, a new conversation about an old concept is happening in soil fertility management. I started working with soils/soil fertility/nutrient management/soil management 29 years ago this March at the West Kentucky Research and Extension Center in Princeton. Some things addressed then are being questioned now, but should they?

Earlier this year the Mississippi State Chemical Laboratory lowered the fee for poultry litter analysis.
Nutrient content of litter used for fertilizer varies up to 60%. Crop producers should have a recent analysis of litter so appropriate land application rates are used.
Previously many growers used less expensive laboratories in Louisiana and Arkansas for their analyses. However, the . . . → Read More: Lower Cost for Poultry Litter Analysis in Mississippi
Acid soils often need liming to aid crop growth and development. Fall applications provide more time for the lime to react with the soil, less stress on the human component, and better field conditions for equipment operation.
Soil acidity problems rarely have dramatic visual symptoms. Affected areas are less hardy or vigorous in growth; the size of . . . → Read More: Lime Need and Value
With harvest beginning, it is time to think about the next crop. Fall liming allows time for the soil to react before the next summer crop is planted, and takes advantage of the (usually) drier conditions for field operations.
Soil pH measures soil acidity, the master variable of soil fertility. Technically pH is the concentration of hydrogen . . . → Read More: Fall 2014 Lime Programs
Considering the abundant rainfall we experienced during April and typically have, it is usually very important to optimize nitrogen fertilizer management. This newsletter discusses best management practices for corn nitrogen fertilization. These recommendations reduce the risk of nitrogen loss and can improve crop response when wet weather is prevalent during the spring. . . . → Read More: Tips to Improve Nitrogen Response for Mid-South Corn
As you look over your fields this winter, be thankful for the tons of potassium (K) present in every acre. It is the most abundant mineral macro-nutrient on earth, which is good because most crops utilize large quantities of it. Among other functions in plants, K is involved in the regulation of water uptake and utilization. . . . → Read More: There’s Good News About the Potassium in Your Soil
After harvest, you immediately face management decisions as you begin preparing fields for next year’s crop. Corn produces far more residue than most crops we are accustomed to, so it can cause considerable benefits or anxiety depending upon how you view it. This article addresses the pro’s and con’s of crop residue and associated management options, including burning. . . . → Read More: Burning Stalks – What does it Really Cost?
