Eficácia de composto orgânico aplicado à produção de alface e de rabanete

Abstract

Human beings always interacted with the environment causing negative consequences and positive and agriculture is an example of this interaction, in which there is direct contact between man and environment. Therefore, it is important to search the use of sustainable systems in order to balance such an interaction. Long ago, the remains of animals and plants are used as fertilizer by farmers, many of these are lost by improper waste disposal and lack of information. These wastes, when collected, sorted and recycled properly, produce good results in its use. The main contribution of this work was the development of an organic compound produced from the remains of poultry manure, wood ash, leaves chopped, phosphate and limestone. The same was available for verification of its benefits in crops of lettuce and radish. In order to verify the effectiveness of the compounds were built four experimental plots, which were planted 400 seeds (200 of lettuce, corresponding to two beds, 200 radish, corresponding to the remaining two beds), the compound adhering to the soil in two beds , one for each culture. Upon completion of the physical-chemical analysis of substrates, as well as biometric of lettuce and radish was proved that, using the compound described here, the species tested, over the developments, had a significant mass gain and growth, favored by a broader role of macro and micronutrients available.
