Weed control methods effect on the hydraulic attributes of a Latosol

摘要: Weed management plays a key role in the minimization of soil physical degradation processes such as compaction and hydric erosion. Different weed control managements can induce distinct changes structure. One important attribute used for analysis modifications structure is water retention curve (SWRC). The objective this work was to verify use physico-hydrical attributes understand effect on Two layers (0–0.05 0.10–0.15 m) six divided into two groups were analyzed: I. no disturbance ground cover (no control, post-emergence herbicide, mechanical mower); II. (hand-hoe weeding, rotary tiller, pre-emergence herbicide). An area native forest reference. results showed that volumetric capacity derived from SWRC be an interesting tool evaluate impact Evaluations air-filled porosity variation different pressure heads also presented findings. Distinct found depths analyzed relation forest.
