Restauración Ecológica del Suelo Aplicando Carbón Vegetal y su Efecto en la Producción de Medicago Sativa.

Abstract

In de province of Chimborazo, Riobamba city, in the San Pedro of Abras neighborhood. The study of ecological restoration on soil was performed by applying different levels of charcoal (10,20 and 30 t/ha) and its effect of forage production of alfalfa Medicago sativa begin evaluated under a block design completely randomized. The best result were obtained by applying 30 t/ha, charcoal since the first cut reached the lowest occurrence time to flowering (40,50 days) increased basal coverage ( 39,35%) and aerial coverage (86,0%) as well as also the best height (87,98 cm) and above the highest forage production in both green fresh (15,80 t/FV/ha/cut) and dried (33,38 t/MS/ha/year) and finally the highest numbers of leaves per stem (103,45). In the second cut the same trend was recorded, where the most efficient responses were archived with the application of 30 t/ha of charcoal, especially with the best basal cover (86,55%) and aerial (95,42%) as well as also the largest production and green forage (15,92 t/ha/cut ), and production in dry matter in 30 t/ha of charcoal because a benefit cost of $ 1,63 was reached. We recommend applying in medicago sativa in higher levels to 30 Y/ ha of charcoal, because a larger amount of green forage by cut was obtained and improved soil quality, which guarantee to obtain and improved soil quality, which guarantee to obtain economic returns that benefic the agricultural and livestock producers besides restoring degraded soils to lower cost and an organic way.
