	bibo:abstract "In a three-year study, the major advantage of a zone\ncotton production system with controlled traffic was\ndetermined to be reduction in tractor operations for field\npreparation and crop management without a reduction in\nyield. The study indicates that tillage is required under any\nsurface where wheels are operated to return the soil to a\nlow impedance for root exploration and to a conductive\nstate for water infiltration. However, the soil managed with\na zone system, with no traffic or tillage after initialization,\nwas stable with lower soil impedance and higher water\ninfiltration than soil in tilled and trafficked plots. Adoption\nof these findings will reduce unit production costs."^^xsd:string;
