Natural farming

The degradation of grasslands via overgrazing negatively affects the environmental and animal husbandry. China has decided to assess the issue by restoring degraded grasslands. Unfortunately, china’s efforts were economically unfavorable. The experiment conducted involved the utilization of natural grasslands to both house and feed chickens to replace the traditional husbandry system. It was determined that the new approach improved surface soil water content and the above plant biomass was not decreased (Liu et al, 2013).This approach increases environmental sustainability by decreasing degradation of grasslands. It is also more economically favorable approach. Furthermore, it has given degraded grasslands the opportunity   to regenerate, and has resulted in the farming of organic poultry.
