Oat Straw Mulching Reduces Interril Erosion and Nutrient Losses Caused by Runoff in a Newly Planted Peach Orchard

Soil erosion is one of the major problems in agricultural areas world, and straw mulching a conservation practice that may reduce soil runoff. How much necessary to runoff? The objectives this study were quantify characterize runoff under different levels oat mulching, as well analyze cost erosion. An experiment was performed site with recently tilled for peach orchard implementation. In ridges row orchard, plots placed order nutrient losses by surface due interril on dates 23 August 2015 13 March 2016, considering treatments composed amounts (0, 1, 2, 4 8 Mg ha−1). results showed use decreased runoff, especially doses ≥2 ha−1, replace available nutrients P, K, Ca via mineral fertilizer varies from US$ 75.4 (no mulching) 2.70 per hectare (8 ha−1 mulching).
