Biological and chemical quality of the soil with the application of manure in an ecological rotation of extensive crops for grain production.

The general objective of this project, which lasts one year, is to develop recommendations on fertilization practices that are best suited to extensive crop rotations for grain production, adapted to the reality of the production sector. The incidence of the application of different types of organic fertilizers in organic extensive crop rotations for grain production, in different aspects of chemical and biological quality of the soil, closely linked to each other, will be evaluated.
