Abstract
The present contribution provides the first agro-economic and ecological account of the in-furrow application of a mineral and an organomineral microgranular fertilizer in comparison to a wide spread mineral band fertilizer in temperate climate regions. The reduction of phosphorus inputs while maintaining the yield of maize plants (Zea mays) is the focus of the study. In a three-year field trial, the dry matter yields gained with the two phosphorus-reduced microgranular fertilizers and standard diammonium phosphate (DAP) fertilization were examined. The application of the organomineral microgranular fertilizer resulted in dry matter yields that were 15% higher (2.8 tons per hectare) than the DAP variant, while higher yields using the mineral microgranular fertilizer occurred only in a single year. The higher yield of the organomineral microgranular fertilizer and the lower phosphorus amounts applied with that product resulted in a moderate phosphorus excess of 2.7 kg P ha-1, while DAP fertilization resulted in a surplus of 25.5 kg per hectare. A similar pattern of phosphorus balance was observed on the plots fertilized with the mineral microgranular fertilizer. We conclude that both tested microgranular fertilizers provide an adequate alternative to the wide-spread DAP fertilization in maize cultivation on fertile soils.
