EFFECT OF THE USE OF SEWAGE SLUDGE ON NUTRITIONAL QUALITY AND PHYTOMASS OF UROCHLOA DECUMBENS

Abstract

The use of sewage sludge allows the reutilization of nutrients with yields equivalent to or greater than those obtained with chemical fertilizers, and may contribute to the improvement of degraded soils. The aim of the study was to evaluate the ability of the ETE sludge to be used together or even as an alternative to conventional chemical fertilization in braquiaria production. Thus, a completely randomized block experiment was carried out, with five treatments and six replications, where the parameters of chemical analysis and leaf mass production of the braquiaria were verified. Data were submitted to statistical analysis and regression analysis. The results show that organic fertilization was equivalent to chemical fertilization.
