Sustainable Intensification of Short Fallows in Shifting Cultivation with Biopolymers

Abstract

The sustainable intensification of the depleted fallow lands has been extensively researched to develop tailor-made management strategies. This synthesis involved a review of the literature and re-analyzing published data on changes in soil physical and chemical properties in land under shifting cultivation. Additionally, the impact of biopolymer application on soil health and plant growth improvement has been described. Present synthesis revealed soil macro-aggregates, water infiltration rate and hydraulic conductivity, and essential soil elements (N, P, K) declined substantially in soil under shifting cultivation practices. Furthermore, it was observed that biopolymer applications decreased total runoff and sediment yield while enhancing soil health and plant growth. Therefore, it is concluded that the biopolymer application is a sustainable method for improving soil properties and short fallow management.
