The sustainable agriculture in Cuba is based in the obtaining of the ecological and organic productions that to favor it development, with the minimum of chemical product. This it required to search of alternative of organic fertilization for the growth and development of the cultivations with acceptable yields and of good quality, besides it this also offer to at soils nutrients and favor the physical, chemical and biological properties. It was carried out an investigation with the objective of establishing technological variants for the efficient use of the crop residuals in the compost production. The alternatives are use to accelerate the compost process and the quality of the formed product is improve. The experiments were carried out with different variants of compost in the first stage. It using diverse residual of crops, as pepper residuals, banana and husk of rice, as well as, two fungi and zeolite to accelerate and improve the quality of process of decompositions the organic materials and was obtained compost with good quality. The time of elaboration of compost decrease with the use of fungus Artrobotys nuciformis, Pycnosporus sp, and zeolite. The environmental and social benefits was obtained with this results.

Nowadays the mineral fertilizers lack and the soil deterioration product to the wrong handling of the same ones, it has made necessary the search of alternatives that provide solution to this situation. In this sense an investigation with the objective of establishing mixtures of organ-minerals manure and to evaluate its quality for the conservation and later application was developed. Two assays were mounted with different mixtures of mineral fertilizer (Urea, SPT and KCl) and organic manure (worm humus, sugar cane residual and bovine manure). Periodic samplings until the 6 months of the mixtures were carried out for the chemical (MO, pH(H2O), N, P, K), physical (apparent density) and microbiologic analyses (Breathing). The results were evaluated 2 statistically and it was obtained that the organ-minerals manure obtained starting from the mixture of until 30% of mineral fertilizer with organic materials (worm humus, phlegm and manure) present good quality. These mixtures are able to be stabilized starting from the 45 days and they can be conserved until the 120 days. The evolution of the CO2 and the content of organic matter are good indicators to detect the stabilization or state of 2 balance of the process. [ABSTRACT FROM AUTHOR]
