Abstract

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