Effect of Animal Waste Based Digestate Fertilization on Soil Microbial Activities, Greenhouse Gas Emissions and Spring Wheat Productivity in Loam and Sandy Loam Soil

The increasing quantities of organic residues are becoming one the most important problems for climate change mitigation. Sustainable utilization technologies required to minimize effect recycling on environment. Nevertheless, treated should be part circular bioeconomy. One promising processes is biogas system, with final products and digestate, which contain valuable nutrients therefore suitable as agricultural fertilizers. However, there lack research data effectiveness digestate environmental factors including soil quality well crop productivity quality. In this study, we compare roles different digestates (chicken manure cow pig digestate) spring wheat productivity, microbial activities, greenhouse gas emissions in loam sandy under controlled conditions. liquid applied was equivalent 170 kg N ha−1 total presented. Overall, results showed that two types responded differently addition digestates, benefits depended characteristics type applied. There a higher activity compared soil. Chicken had highest value dehydrogenase biomass C 9.23 µg TPFg−1 h−1 175.6 g−1 across types. CO2 N2O were moderately when peak emission at 0.0107 occurred soil, regular patterns observed fertilized manure. both 0.007950 mg 0.5667 respectively. yield varied irrespective receiving ecosystems supplying essential coupled its benefits, makes it an encouraging prospect temperate zones.
