Biological nitrogen fixation and water use of fodder legumes during conversion to organic farming under site conditions of the pannonical region in eastern Austria
Abstract
In organic farming systems, biological nitrogen fixation is the main source of nitrogen. Under the pannonical climate conditions, legume growth and biological nitrogen fixation can be limited by dry periods during the growing season. The overall aim of this project is to optimise fodder-legume dominated crop rotations in organic farming systems. In a three-year experiment, legume-grass-mixtures and monocultures (alfalfa, red clover, white sweet clover) shall be compared in a stockless mulching system and a system with cutting for fodder use with respect to dry matter and N yield (above ground plant biomass and root biomass) of legume crops, capacity of biological N fixation, water use and water use efficiency and N balances of different fodder legumes.
