Resumo: | The disintegration of soil particles affects its productive capacity, resulting in compression, erosion and nutrient losses. This study aimed at evaluating the aggregates quality and stability of a Yellow Latosol, in a randomized blocks design represented by Urochloa decumbens and Urochloa brizantha, with and without mineral fertilization, and two sampling forms (rows and between rows), in three sampling depths. The undeformed soil samples collected were shattered and passed through a 9.52 mm sieve and, after drying, through a 2.00 mm, 1.00 mm, 0.50 mm and 0.25 mm sieves, according to the following diameters classes: 9.52-2.00 mm, 2.00-1.00 mm, 1.00-0.50 mm and 0.50-0.25 mm, by using dry sieving. These aggregates were also separated by wet sieving and the dispersed clay and root dry matter were determined. Aggregates larger than 2.00 mm showed high stability, in the 0.00-0.05 m layer, when compared to the aggregates from smaller classes, with no effect of sampling and fertilization site on the aggregates size and stability. There was no difference for the two species analyzed, sampling method and fertilization on the aggregates formation and stability. |

Neste estudo, foi avaliada a qualidade e estabilidade dos agregados de um Latossolo Amarelo, em delineamento de blocos ao acaso, representado por Urochloa decumbens e Urochloa brizantha, na presença e ausência de adubação mineral, e por duas formas de amostragem (fileiras e entre as fileiras), em três profundidades de amostragem. As amostras indeformadas de solo coletadas foram destorroadas, passadas em peneira de 9,52 mm e, após secagem, em peneiras de 2,00 mm; 1,00 mm; 0,50 mm e 0,25 mm, obedecendo às seguintes classes de diâmetro: 9,52-2,00 mm; 2,00-1,00 mm; 1,00-0,50 mm e 0,50-0,25 mm, por peneiragem seca. Estes agregados foram, também, separados por peneiragem úmida, sendo, ainda, determinada a argila dispersa e a massa seca de raízes. Os agregados maiores que 2,00 mm apresentaram estabilidade elevada, na camada de 0,00-0,05 m, em comparação aos agregados de menores classes, não havendo efeito do local de amostragem e de adubação sobre o tamanho e estabilidade dos agregados. Concluiu-se não haver diferença entre as duas espécies estudadas, forma de coleta das amostras e adubação, na formação e estabilidade de agregados.
