Conteúdo: | Experiments in Brazil and Puerto Rico on highly weathered, acid soils demonstrate that subsoil acidity limits crop yields even when the plow layer is adequately limed. This limitation is probably the result of inhibition of root proliferation in the subsoil; and, consequently, the water stored in the subsoil is unavailable to crops. This subsoil water is essential to crops, because several consecutive days without rain are common during most growing season. Limitations imposed by subsoil acidity can be minimized as follows: by selecting for immediate development those areas where subsoil acidity is least severe; by selecting locations where rainfall distribution and soil-water storage capacity will minimize dependence of crops on subsoil water; by selection crops that are tolerant of subsoil acidity.
