Environmentally friendly methods for grassland fertilization are to prove. Reduction of greenhouse gas emissions and especially ammonia emissions can be reached by using modern slurry application techniques. The use of trail hoses, slurry injection and swivel distributor are to compare. We are testing the different techniques at four pilot farms in the region Oberschwaben.
Our aim is to get more information about the use of modern techniques in order to transform the results for the agricultural practice. We expect results which we can publish in farmers magazines and special information for farmers and farm advisers. We expect that different methods have different DM-yields, a different nutrient availability and also effects on the grassland swards.
