Soil & tillage research vol:58 issue:1-2 pages:31-44
Tillage operations transport large amounts of soil from convex slopes and deposit on concavities in hilly cultivated areas. Field experiment was conducted to assess tillage induced soil displacement and its effects on soil properties and wheat (Triticum aestivum L.) biomass production. The study was done on 3.5 ha fertilized and wheat seeded hillslope (14-21% slope) located 100 km north of Athens. Greece. Numbered aluminum cylinders (700), each 10 mm diameter by 10 mm height. were buried in soil as soil movement tracers (SMTs) to estimate soil displacement as a function of moldboard plowing with two depths in up-slope and down-slope directions. Furthermore. clay, organic matter, rock fragment content, phosphorus and Cs-137 were determined on 81 soil bulk cores to estimate soil redistribution rates along the study hillslope. Soil depth and soil water storage were measured in 81 soil sites and related to the wheat biomass production.
