This work was carried out under greenhouse conditions, in 1997, at Faculdade de Agronomia, Universidade Federal do Rio Grande do Sul (UFRGS). A split plot randomized complete block experimental design was used, with six replications, to evaluate root lengths, average radius, roots surface and dry matter of roots with the objective to evaluate the effect of humic compounds addition in the development of ryegrass roots. Ryegrass forage was grown in pots with irrigated sand with four levels of humic compounds […]
