Description
Core Ideas
  • Agronomic efficiency of organomineral fertilizers higher than biosolids granules.
  • Organomineral fertilizers reduces the risk of soil P build‐up compared with biosolids.
  • Conversion of sewage sludge into organomineral fertilizers improves the fertilizer value of biosolids.
Field‐scale experiments in four crop seasons established the agronomic performance of biosolids‐derived organomineral fertilizers (OMF) for winter wheat (Triticum aestivum L.) production in England. Two OMF formulations (OMF10 10:4:4 and OMF15 15:4:4) were compared with urea and biosolids granules (≈5:6:0.2) to determine crop responses and fertilizer effects on soil chemical properties. Fertilizers were applied at N rates between 0 and 250 kg ha−1 at regular increments of 50 kg ha−1 N. Average grain yields with OMF10 and OMF15 were higher than with biosolids granules, but lower than with urea (P < 0.05). The optimum N …
