Nitrogen and Phosphorus Availability Following Topsoil Application of Mineral and Organomineral Fertilisers (OMF)

Abstract

Abstract. The aim of this study was to determine the availability of N and P resulting from the soil application of a novel organomineral fertiliser in comparison with urea (46% N) and single superphosphate (% of total OMF-P applied). Despite this, a change in soil-P index from 5 to 6 was observed after the 90 days incubation period but the overall increase in soil-P status was marginal in both soils. For SSP,. The application of SSP induced a significant (p<0.001) increase in soil-P levels compared with the controls which led to an overall increase in soil-P index from 5 to 6. The results of this study aided the development of a strategy for the use of OMF in winter cereal crops.

Soil and crop responses following application of biosolids-derived organomineral fertilisers to ryegrass (Lolium perenne L.) grown in pots

“…This paper summarises the work reported by the authors in Antille et al (2014a), which supports findings from previous studies (Antille et al, 2012(Antille et al, , 2014b conducted at the laboratory-scale. In England and Wales, the disposal of sewage sludge (biosolids) follows a number of routes which include, most importantly, recycling to farmland (72%), incineration (18%), land reclamation and restoration (6%), and landfill (1%) with a total production (dry solids basis) estimated at 1.6 million tonnes per year (DEFRA, 2011).…”
