Soil fertilization with the use of basalt and animal residues and their effects on soybean yield

Abstract

The use of basalt used with animal residues can be an efficient fertilizer alternative for soybean crops. The objective of this study was to evaluate the effect of doses of basalt powder with cattle manure and chicken litter on soybean yield, using soluble chemical fertilization (NPK) as a reference. The experiment was carried out in DBC with factorial arrangement (5 x 2) + 1, in four replications, using five basalt doses (0, 4, 8, 12 and 16 t ha-1) associated with cattle manure and chicken litter and an additional treatment with soluble chemical fertilization (NPK). The following parameters were evaluated: number of pods per plant, number of grains per pod, weight of one thousand grains and yield. The yield of soybean cultivated with basalt and chicken litter was on average 3,462.8 kg ha-1 and with cattle manure it was 3,439.2 kg ha-1. There was no effect of basalt rock dust and animal residues on any of the soybean yield components, but even so, expressive values were obtained, maintaining good yield results. The components of soybean production and yield found with the application of basalt associated with the residues were the same as those found with the use of soluble chemical admixture.
