0 objetivo deste trabalho foi avaliar a influência de camadas compactadas subsuperficiais em uma Terra Roxa Estruturada (TR) e um Latossolo Roxo (LR) no desenvolvimento da parte aérea e na quantidade de nutrientes do feijoeiro, em condiçoes de casa-de-vegetaçao. As plantas foram conduzidas até 45...

Understanding the problems of grazing land in vertisol areas and seeking long-lasting solutions is the central point where mixed crop livestock is the second stay for the majority of the population. In order to understand this, the current study was conducted at two sites, one with 0-4% slope and...
