This was reduced to 13 ± 4% of total N applied when food-based digestate was bandspread in the autumn, highlighting the effect of N losses via overwinter nitrate leaching. Manure-based digestate applied in spring had a mean NUE of 52 ± 8% which decreased to 15 ± 6% of total N applied for autumn applications. For both materials, there was considerable variation between the NUE results obtained from the individual experimental sites; however, this was not surprising given the complex systems represented by the 15 experimental sites, including differences in soils, cropping, weather and digestate properties, and is commonly observed in experiments with other organic materials (e.g. livestock slurries). | Publication Type: | Report | Publisher: | Waste and Resources Action Programme (WRAP) | Place of Publication: | Oxon, United Kingdom | Fields of Research (FoR) 2008: | 050399 Soil Sciences not elsewhere classified 070106 Farm Management, Rural Management and Agribusiness 070101 Agricultural Land Management |
