Description:
Water deficit and soil degradation have become some of the major problems for crop production in semi-arid regions, as it is the South East of Spain. As a matter of fact, considerable productivity loss and risk of erosion have to be taken into account in these areas, especially those with an horticultural use (Davis, 1989). Utilization of sewage sludge in agriculture. Agricultural Progress 64, 72-80]. Horticultural soils are highly vulnerable and prone to erosion, as vegetables are generally fast-growing species under intensive exploitation regimes. High-rate chemical inputs contribute to horticultural soil degradation and have a dramatic effect on soil microbial population and nutrient balance whilst, at the same time, have a counter-effect on price competitiveness of the vegetables to be commercialized. In this paper we monitored variations in physical, chemical and biological properties of a cauliflower plot where four increasing quantities of compost were applied. We carried out a three-stage sampling schedule in order to check the effect of compost applications doses. We conclude that a 2kg compost/m^2 application had a positive effect on physical and biological properties of the soil and provides a supply of nutrients to grow cauliflowers on its surface under intensive exploitation regimes without loss in biomass yield.
