Soil and water losses due to agricultural mismanagement are high non-sustainable in many orchards. An experiment was set up with rainfall simulation at 78 mm h–1 over 1 hour on 20 paired plots of 2 m2 (bare straw covered) new persimmon plantations Eastern Spain. Effects cover the control soil were assessed. addition 60% (75 g m–2) resulted delayed ponding runoff generation consequently reduced from 13% total rainfall. The raindrop impact thus sediment detachment 1014 47 plot–1 h–1. erosion rate 5.1 0.2 Mg ha–1 mulch found be extremely efficient reducing rates.
