Stubble‐Mulch Tillage Versus Plowing With Nitrogen Fertilization With Regard to Nutrient Uptake by Cereals1

Synopsis 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.
