Adaptation of N Catch Crop Species to Simplified Management

摘要

The use of catch crop in between maize crops on an irrigated maize monoculture system has been proved as an efficient way to minimize N leaching during winter (Domingo et al, 2004). Nevertheless, there is a need to look for a way to stablish those catch crops at a reduced cost to be worth in practice. At the Emporda area (NE Iberian peninsula; Mediterranean conditions), maize is irrigated using a furrow system which do not allow direst sowing after maize crop. The aim of this work was look for a sowing system for catch crops able to reduce implantation costs without reduction of the efficiency of them.
