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

  1. Wray L. Winterlin,

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.

Nitrogen fertilizer largely overcame this effect.
