Row Cleaners In No-Till Corn, Lloyd W. Murdock, James H. Herbek, Tim Gray
Soil Science News and Views
Row cleaners are planter attachments mounted in front of the double-disc openers on planters. They are designed to move most of the surface residue to the sides of the row, allowing no-till planting into a band with a fairly clean surface. This attachment is best suited for wet, cool soils to allow a more rapid warming of the soil surface, on rough soil to allow some smoothing before planting, and in heavy residue to prevent "hairpinning" of residue into the planting slot. There is evidence that cleaning the residue from the row raises soil temperatures which results in quicker corn …
Poultry Litter As A Nitrogen Source For Corn, Monroe Rasnake, Larry Reber
Poultry Litter As A Nitrogen Source For Corn, Monroe Rasnake, Larry Reber
Soil Science News and Views
Development of an intensive poultry production industry in western and south-central Kentucky will make poultry litter available to many farmers. It is estimated that 45, 000 tons per year will be produced just in the Jackson Purchase Area. One of the most efficient uses of this litter is as a nitrogen fertilizer source for corn.

Current Research On Soil Nitrate Testing For Corn In Kentucky, John H. Grove
Soil Science News and Views
Concern has been expressed that growers do not have the "slte-specific" information they need for more efficient nitrogen (N) fertilizer management on a field-by-field basis. Soil testing has routinely been used to guide recommendations for phosphorus, potassium, and lime additions to individual fields, but effective soil N test procedures have long eluded soil scientists working in warm, humid regions with substantial winter rainfall. Now, recent research suggests that a new soil test procedure has some potential to guide fertilizer N applications for corn. The purpose of this report is to define the concept of soil nitrate testing; to describe how …
