Abstract
The effect of three different soil tillage systems (plow, subsoiling and no-tillage) on soil losses by runoff and “splash”, was determined in situ using a rain simulator. These determinations were carried out in a field experiment under the Project “Soil Tillage in Dry and Irrigated Farming” (EU Program AGRIMED), installed in a Cambisol from granite, Inland Central Portugal (Fundão). The tests were carried out after removing of mulch and 5 mm of the surface layer. The effect of soil tillage treatments on one hour mean rates of soil loss by runoff, soil loss by “splash”, and total soil loss were highly significant.
No-tillage treatment significantly decrease the soil loss by runoff, the soil loss by “splash” and consequently the total soil loss in relation to plow (60%), as previously verified in relation to runoff. Subsoiling had an intermediate behaviour in all cases.
In conclusion, no-tillage seemed to be the best treatment to protect soil from erosion. As it was previously concluded for runoff and infiltration, at least in the initial situation (2-years), with a sandy loam soil with low content of organic matter, subsoiling was not justified.
