Comparisons of infiltration capacitites in different parklands and farming systems of semi-arid Burkina Faso

摘要: The organic matter content of the soil (SOM) is a key property for aggregation and water infiltration in semi-arid parklands West Africa. This study comparing capacities (IC) fields, where SOM managed different ways, two villages western part Burkina Faso. Steady-state IC was measured with tension disc infiltrometer. In village Dossi, measurements were made before tilling (in June 2005) under between trees fields Vitellaria paradoxa Faidherbia albida addition extra leaves latter field. Bondoukuy capacity after plots or without compost annual biannual tillage. results showed that higher (104 mm/h) than (69 Vitellaria-field (117 Faidherbia-field (58 mm/h). increases (79 mm/h vs. 58 tillage could also have an improving effect (75 62 demonstrated potential by managing matter.
