Beschreibung

The spatial distribution and properties of rainfed orchards in semi-arid environments result from complex interactions between man and the physical and economical environment. It is shown how the practice of clean sweeping (i.e. frequent shallow tillage) influences the orchard water balance and how the removal of traditional soil and water conservation structures affects the connectivity of overland flow to the river system. Clean sweeping constrains the root growth in the plough layer, so that the trees cannot access the water from small rain events. It appears that the practice of clean sweeping limits the water availability in orchards on loamy soils with an annual rainfall in the order of 300 mm. The observed decline in conservation structures like terraces and check-dams leads to an increase in the connectivity of water and sediment to the river system. An alternative for these traditional techniques to retain the water and the soil is the application of cover crops. Field evidence and water balance simulations suggest that cover crops are feasible in areas with an annual precipitation of 500 mm or more.

Klappentext

The spatial distribution and properties of rainfedorchards in semi-arid environments result fromcomplex interactions between man and the physical andeconomical environment. It is shown how the practiceof clean sweeping (i.e. frequent shallow tillage)influences the orchard water balance and how theremoval of traditional soil and water conservationstructures affects the connectivity of overland flowto the river system. Clean sweeping constrains theroot growth in the plough layer, so that the treescannot access the water from small rain events. Itappears that the practice of clean sweeping limitsthe water availability in orchards on loamy soilswith an annual rainfall in the order of 300 mm. Theobserved decline in conservation structures liketerraces and check-dams leads to an increase in theconnectivity of water and sediment to the riversystem. An alternative for these traditionaltechniques to retain the water and the soil is theapplication of cover crops. Field evidence and waterbalance simulations suggest that cover crops arefeasible in areas with an annual precipitation of 500mm or more.
