Summary
According to literature reports farmyard manure application caused higher amounts of microbial activity in soils compared to mineral fertilizers. If lab tests have been carried out (e.g. enzyme activity, microbial biomass) results can be attributed to soil properties, as experimental conditions have been constant. With plots of a long-term field trial it has been studied whether organic or mineral fertilization has any effect on soil temperature (depending on different crop density in each treatment) and, by this way, also on N mineralization. Soil temperature was higher in organically than in minerally fertilized winter rye, but only on sunny days, not on cloudy ones. Differences have been measured to a soil depth of 15 cm. However, N mineralization did not differ significantly between fertilization treatments.
