SR21089Long-term dairy manure application in a no-tillage system: crop yield and soil fertility
In rotation system with annual crops, maize and black oat showed greater response to annual manure application, in addition to mineral fertilisation, with maximum yield for a dose of 150 m3 ha−1 year−1. Although it was applied to the soil surface, the manure provided chemical improvements in deep layers. The increase in yield with manure application was attributed to improved soil acidity attributes and the effect on nutrient availability.
