Resumen
Descripción
The intensive use of agricultural machinery has been one of the reasons that caused degradation soil, that's why this investigation was conducted in order to evaluate the responses caused by different tillage systems on some hydro soil properties and in the extraction of nutrients for growing wheat ( Triticum durum L.) in experimental plots of the Institute of Natural Resources and Agrobiology fromSeville, Spain. For the study, a sample design was used. The treatments were: conventional tillage (CT) and conservation (LC) in experimental plots and long-term no- till (NT) and new traditional tillage (NTT) in short duration, on plots of 240 m 2 and 140 m2, respectively, in Fluvisol soil. The pilot phase bulk density and water content in the soil were evaluated. Besides the extraction of nutrients by the crop foliage, grain and yield were determined. The results showed significant differences among treatments in the extraction of N, P and K in different parts of plant assessed, highlighting the CT with higher extraction of nutrients for growing and higher performance, the most appropriate, considering the environmental benefits of the same.
