Abstract

It is known that organo-mineral fertilizers have the capacity to retain positively charged nutrients since they perform a cation exchange with these ions, such as the ammonium ion, and then release it slowly as the crop requires it; this type of system is called occluded fertilizer. A simple and fast methodology is used to perform this evaluation, using a syringe system adapted to the field conditions required by a crop, and by means of kinetics the nitrogen released is evaluated. Considering the conditions recorded in the literature for a crop such as chili (Capsicum annuum): 200 kg N/ha, 176 kgP2O5/ha and 300kgK2O/ha, it was adapted to the proposed system, applying mineral fertilizer alone and doping with different amounts of compost. Five systems were proposed with 0, 0.5, 1.0, 1.5, 2.0 g of compost and the same amount of mineral fertilizer, in this way it was estimated which is the optimum concentration of compost that the fertilizer should support in order to reduce the leaching of nutrients; finding that the concentration of 0.5 to 1.0 g of compost is the ideal to retain the nutrient that comes from the mineral fertilizer.
