Efeito da calagem e da adubação fosfatada em solo ácido e de baixa fertilidade, na cultura de trigo

The effect of phosphate manuring associated with liming on wheat yield was tested in an Ortho-Dark Red Latosol, at Capao Bonito Experimental Station. There was a significant response on the wheat grain yield following application of phosphorus and lime. The yield increase was positively correlated to the phosphorus concentration, but 2 t/ha or 4 t/ha of lime had similar effect. Limestone applied prior to plowing resulted in better yield than after.
