Avaliação da fertilidade de solos de Viçosa, Minas Gerais; uso de microparcelas
Palavras-chave:
fertilidade solo, microrganismos vegetais, método Neubauer, análise química, ensaios campoResumo
This paper reports results obtained with the instalation of the corn micro-plots method in order to evaluate soil fertility in Viçosa; obtain data that may relate wet weight and dry weight; study maximum values that can be added to soils in order do reach the limit of sline concentration and study the possibility of using the method in correlation studies with chemical analysis of soil.
The results have shownthatthere is a significant correlation between wet weight and dry weight and dry weight; the doses used were insufficient to show a harmful effect of phosphorus concentration but it was observed in the case of nitrogen (500 kg of N/ha) and potassium (113 kg of K,0/ha).
The method has been whown capable of supplying indications that deservebeing studied in order to use it for correlation studies of chemical analysis content of soil and relative growth
