In protected vegetable systems of the Mediterranean area, having bare soil for several weeks in late summer, post cash crop harvest, may induce soil degradation. Providing a soil cover in any period is key to preserve the soil's biological activity and maintain good agronomic conditions (e.g. soil structure) for the following crops.

Conventional pest control based on the use of synthetic insecticides is very effective, however, this has important negative effects on the environment such as the loss of farmland biodiversity, especially in the group of invertebrates, including many beneficial organisms. Another key problem is the presence of insecticide residues in surface and groundwater or, potentially, in harvested products.

The review is published in the Journal of Agronomy. Healthy soils are essential for progressive agronomic activities. Organic fertilization positively affects agro-ecosystems by stimulating plant growth, enhancing crop productivity and fruit quality and improving soil fertility.
