Effect of Digestate, Liquid and Solid Manure Application on Chemical Properties of Soil

Agnieszka Jolanta Wysocka-Czubaszek

Abstract

The growing number of biogas plants results in increasing digestate volume used as fertilizer on arable land. This study compared the influence of digestate addition on soil chemical properties with traditional organic fertilizers such as liquid and solid cattle manure and with mineral fertilizer. The digestate supplied soil with a significant amount of NH4-N, whose nitrification was slower comparing to soils treated with mineral fertilizer and liquid cattle manure. Digestate also slightly increased concentration of water-soluble phosphorus in soil and added high amounts of plant-available potassium and dissolved organic carbon. Therefore, the application of digestate should follow the same rules as traditional liquid fertilizers; however, its agronomic use should be based not only on N, but also on P and K content.
