Kokkora, Maria I. and Antille, Diogenes L. and Tyrrel, Sean F. (2009) Considerations for recycling of compost and biosolids in agricultural soil. In: Soil Engineering. Soil Biology, 20 (3). Springer, Germany, pp. 195-215. ISBN 9783642036804


Regulatory pressures, economic factors and the increasing production of organic waste promote the recycling of compost and biosolids to agricultural land. Sustainable recycling requires an in-depth understanding of the various processes involved when dealing with organic materials. These include interactions in the soil–crop system and the wider environment. The fertiliser value of compost and biosolids depends on the nutrient content of the materials, notably nitrogen, phosphorus and potassium, and their availability to plants. Compost and biosolids constitute slow release fertilisers since most of the nitrogen and phosphorus is not readily available for plant uptake. Furthermore, imbalances in their nutrient composition can negatively affect their agronomic performance. The development of nutrient-enriched biosolids (organomineral fertilisers) appears to be a sustainable alternative for recycling to agricultural land as it deals with the problems associated with nutrient imbalances and release. Further research is necessary to develop suitable techniques for compost nitrogen enrichment in order to improve its nitrogen fertiliser value.
