Short‐term and residual availability of nitrogen after long‐term application of organic fertilizers on arable land

Abstract: Knowledge on short‐term and long‐term availability of nitrogen (N) after application of organic fertilizers (e.g., farmyard manure, slurry, sewage sludge, composts) provides an important basis to optimize fertilizer use with benefits for the farmer and the environment. Nitrogen from many organic fertilizers often shows little effect on crop growth in the year of application, because of the slow‐release characteristics of organically bound N. Furthermore, N immobilization after application can occur, leading to… Show more

“…Another factor indirectly affecting nitrate leaching risk is often an increase of the total amounts of available organic manures after implementation of biogas plants due to digestion of dedicated energy crops (Möller et al 2011), resulting very often in higher overall organic manure applications at inconvenient periods. The significantly lower N efficiencies of organic manures, including unseparated digestates, in comparison to mineral N fertilizers (e.g., Gutser et al 2005) are a further reason for higher N loss risks after setup of such biogas plants as higher amounts of total N are often applied to secure the N demand of crops.…”

“…4). This result is reasonable because the value of available N relates to quickly-decomposable soil organic N, rather than slowlydecomposable soil organic N. Gutser et al (2005) have found that the degradability of organic matter in biogas slurry (equivalent to ADM) is small.…”

“…However, in the year of application only a certain amount of this organically bound nitrogen will be mineralized into plant available N forms. Based on data from Gutser et al (2005) this so-called 'mineral fertilizer equivalent (MFE)' for feather meals can be estimated to 60% of the total applied N. Therefore, 1600 kg feather meal is needed to replace 125 kg nitrogen.…”

“…The production was assumed to take place in Germany or bordering Table 1. Characteristics of the secondary raw material fertilizers products considered for the carbon footprint calculation (based on the data from Choi and Nelson (1996), Gutser et al (2005), and Hartz and Johnstone (2006) states. GHG emissions of meat production can be found in Table 2.…”
