Potentialities of coffee agroindustry and urban waste in the improvement of agricultural production.

Abstract

The present research work was developed in the productive areas of the Faculty Agroforestry of Mountain, of the University of Guantanamo, with the objective of establishing a methodology of composting that overcomes the difficulties of these residues to be used as fertilizers or amendments of the properties of the soil and for the proper development of tomato plants. Among the main results of this work were that the use of coffee pulp and biosolids decreased the composting time of the Urban Solid Waste and most of the organic fertilizers produced have adequate chemical and microbiological properties to be applied in agricultural production systems. The experimental results obtained were subjected to completely randomized Analysis of Variance and the normality of the data was previously checked by the Kolmogorov-Smirnov test and the homogeneity of variance by the Bartlett test.
