Recovery of degraded pasture using biosolids and Moringa oleifera: Review

Abstract

Livestock occupies a prominent place in the Brazilian economy, especially beef and dairy cattle raising, so the success of this sector is essential for the country's growth. However, the productivity of this sector is closely linked to the quality of pastures, as these are the main food source for cattle, and about half of the Brazilian pastures are with some degree of degradation, thus reducing the productivity and profitability of this sector. Because of this, the search for pasture recovery technologies has been sought, especially those that reduce costs in the recovery process, seeking to increase pasture productivity and quality, preserve the environment and maximize profits for producers. In view of this, the use of new sources of fertilization and the implementation of silvopastoral systems has been widely studied and applied to the recovery of these areas, among them we can highlight the use of biosolids, which is an organic fertilizer from the treatment of sanitary sewage, as well as the implementation of livestock-forest using Moringa oleifera a leguminous plant which fixes nitrogen in the soil and can serve as a food source for the animals. Thus, this work describes the scenario of degradation and Brazilian pastures and the use of biosolids and moringa in the recovery of these areas.
