Description

The food production is not only one of the main pillars of the Society but also, undoubtedly one of the most important. The final consumer is increasingly aware of the importance of food and, as such, requires for their benefit, greater quantity, variety and quality of food, and that food producers have to adapt without fail, innovating and improving their production techniques. Therefore it is necessary to call upon to the use of low-cost techniques which allow a quality and economically profitable sustainable production. Once the environmental degradation is increasing, and intensive crops are known to increase that impact, it is a smart option to resort to the use of organic residues as fertilizers which, in turn, are more environmentally friendly and economically profitable. We conducted a field test in order to study the behavior of different organic materials and its potential as crop fertilizer. The test was conducted using porous capsules and after the waste-filled capsules were buried, adjacent soil sampling was made, and this composition analyzed in order to determine its potential as a fertilizer. The mineralization of organic matter in the soil was also observed during the three months of the test (organic Matter, N, P and K).
