(2014) Phosphorus release characteristics from biosolids-derived organomineral fertilizers. Communications in Soil Science and Plant Analysis, Volume 45, Issue 19, 2014, pp. 2565-25760010-3624https://doi.org/10.1080/00103624.2014.912300http://dspace.lib.cranfield.ac.uk/handle/1826/9838This study investigated the availability of phosphorus (P) following soil application of a novel biosolids-derived organomineral fertilizer (OMF15; 15:4:4) in comparison with single superphosphate (0:18:0). Two soil types of contrasting characteristics were incubated over a period of 90 days at 25 °C and maintained near field capacity. Phosphorus was applied at rates equivalent to 0 (control), 150, and 300 kg ha−1 of P2O5, respectively. Availability of P from OMF15 was low throughout the experiment accounting for less than 6.5% of total OMF15-P applied. It was shown that after the 90 days incubation period, the overall increase in soil extractable P in OMF15-treated soil was marginal in both soil types. For single superphosphate (SSP), P availability ranged from 16% to 46% of total SSP-P applied. Application of SSP increased soil extractable P levels significantly (P < 0.001) compared with unfertilized control soils. The results of this study aided the development of fertilization strategies for the best use of OMF produced from nutrient-enriched biosolids granules for applications in winter cereal and grass crops in England.enAttribution 3.0 Unportedhttps://creativecommons.org/licenses/by/3.0/Biosolids granulesFertilizer phosphorus availabilityOrganomineral fertilizersOMFSoil P dynamicsArticle
