Diagnosis of soil on coffee (Coffea arabica L.), corn (Zea mays L.) and bean (Phaseolus vulgaris L.), community of Santa Julia, El Crucero, Managua

Abstract

One of the most important parameters in agriculture is the soil nutrient status, as well as the management of farmers. In 2014, through the program Desarrollo Participativo Integral Rural (DEPARTIR), soils of 34 production lots of 17 production units in Santa Julia community, El Crucero, Managua, were sampled at depth of 25cm. Land was planted by coffee (Coffea arabica), corn (Zea maysL.) and bean (Phaseolus vulgarisL.). The factors affecting land use were analyzed by correlation analysis, ANOVA and correspondence analysis at N, P, K, Mg, Ca, MO, CO and pH. The total N, and altitude were correlated. Nighty five percent of the areas had 10.5 hectares, with predominance of coffee cultivation. Chemical fertilization is a common practice in the production units and at the crops studied. The samples taken in corn plots were homogeneous both at internal and external production units; but not in coffee. Planting areas, destination of the production and application of chemical fertilizers, showed high relationship.
