The use of the biocompost as an organic emendation in agriculture, is a significant option as a suitable end use.

Apart from evaluating the effect of the compost made from rice stalks and sludge from purifying plants on a series of species characteristic of the Natural Park’s ecosystems (psamofilas), the compost was used to emend a franco clayey ground used in the cultivation of citrus fruits. Its effect on the properties of the soil and the mineralisation of the organic matter was observed. The results showed an increase in organic matter but not in humic acids nor in other analysed properties of the soil. Nevertheless, and based on the results obtained in this study, it can be stated that the composting of the waste from the rice from the north of the Albufera Natural Park and the sludge from the Purifying Plant in Pinedo in Valencia, is a valid strategy for minimising the negative impact of this waste and at the same time for contributing to the protection and improved management of the resources in this area of Valencia.
