Abstract | A field-scale trial was established to investigate the agronomic efficiency of novel organomineral fertilisers (OMF) produced from nutrient-enriched sludge granules. Two OMF formulations were tested: OMF15 (15:4:4) and OMF10 (10:4:4) which were compared with urea and biosolids granules applied to a grass crop over a period of two years. The fertilisers were applied at N rates in the range of 0 (control) to 250kg ha-1 at regular increments of 50kg ha-1. Results showed that the calculated agronomic efficiencies with OMF were in the range of 25 to 35kg kg-1 which were approximately double than those of biosolids and comparable to those obtained with urea (range of 30 to 37kg kg-1). Olsen's P in OMF-treated soil did not show significant changes (P>0.05); therefore, soil P Index was not affected. This result supported the reasons for the proposed OMF formulations and demonstrated the advantage of the products compared with biosolids which resulted in significant (P<0.05) increases in Olsen's P. It was also demonstrated that the application of OMF at rates equivalent to the optimum N rate for the grass-soil system should not induce significant changes in soil P Index in the longer-term including application to soils with already satisfactory P levels. Fertiliser application strategies (N rates and timing of OMF application) are discussed which will enhance agronomic and environmental performance. |
