Reduce wind and/or precipitation EROSION . CONDITIONS WHERE PRACTICE APPLIES On irrigated lands susceptible to irrigation-induced EROSION , excluding peat soils, andwhere the sodium adsorption ratio (SAR) ofirrigation water is less than 15; On areas where the timely establishment ofvegetation may not be feasible or wherevegetative cover is absent or inadequate; On areas where plant residues areinadequate to protect the soil surface fromwind EROSION ; and On sites where distu
