Water: Use no tillage instead of reduced tillage
A controlled study in 1994–1999 in a rainfed legume-cereal field near Barcelona, Spain, found more water in soils with no tillage, compared to reduced tillage. Water availability: More water was found in soils with no tillage, compared to reduced tillage (33 vs 29 mm mean topsoil water content in February–May). Methods: No tillage or reduced tillage was used on one plot each (90 x 30 m plots). A cultivator (August), a chisel plough (September), and a harrow and roller (November) were used for reduced tillage (depth not reported). Herbicide was used for no tillage (August). Herbicide was used in both plots in September and January, and fertilizer was added in October. Seeds were sown with a seed drill in December and crops were harvested in July. Crop residues were removed from all plots before tillage. Water was measured weekly (February–May, two time-domain reflectometer probes/plot, 20 cm depth).

Water: Use no tillage in arable fields
A controlled study in 1994–1999 in a rainfed legume-cereal field near Barcelona, Spain, found more water in soils with no tillage, compared to conventional tillage. Water availability: More water was found in soils with no tillage, compared to conventional tillage (33 vs 26 mm mean topsoil water content in February–May). Methods: No tillage or conventional tillage was used on one plot each (90 x 30 m plots). A cultivator (August), a mouldboard plough (September), and a harrow and a roller (November) were used for conventional tillage (depth not reported). Herbicide was used for no tillage (August). Herbicide was used in both plots in September and January, and fertilizer was added in October. Seeds were sown with a seed drill in December and crops were harvested in July. Crop residues were removed from all plots before tillage. Water was measured weekly (February–May, two time-domain reflectometer probes/plot, 20 cm depth).

Methods: Reduced tillage or conventional tillage was used on one plot each (90 x 30 m plots). A mouldboard plough was used for conventional tillage, and a chisel plough was used for reduced tillage, in September (depths not reported). Herbicide was used in both plots in September and January, and fertilizer was added in October. Seeds were sown with a seed drill in December and crops were harvested in July.
