Summary

Organic farms without or with a too low animal livestock try to replace farmyard manure by using plant based organic fertilizers, e.g. legume biomass as green meal or grain meal. When applying such fertilizers, it is necessary to know their nitrogen mineralisation intensity in relation to farmyard manure. In an incubation test over three weeks (25 °C, 45% maximum water holding capacity) alfalfa meal showed a lower and faba bean meal a much higher nitrate N mineralisation than farmyard manure (15 and 69 ug g-1 dry matter, respectively, compared to 25).The largest amount was released from castor meal (99 ug g-1). After one week farmyard manure had the largest N release with 28 ug g-1.
