Stubble-mulch tillage compared to plowing, with and without nitrogen, on corn, oats and wheat during 2 years on 4 fields at Lincoln, Nebraska, produced plant tissue and grain of similar content of Ca, Mg, P and K. The N content of plant tissue produced by stubble-mulch tillage tended to be lower than that produced by plowing in most cases; yields also tended to be lower with the former. Nitrogen fertilizer largely overcame this effect.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
