| Economic benefits that arise from conservation farming practices need to be assessed over several years to account for improvements in soil structure and nutrient levels. A gross margin model was used to assess benefits over the eight-year period 1999-2006 for 12 regions in the central west of NSW. The annual benefits from improved soil structure ranged from $2.46 to $12.82 per hectare (ha). A reduction in tractor power produced annual savings in the range of $0.60 to $4.05 per ha. The cost of soil compaction by livestock grazing on crop areas ranged from $3.41 to $14.90 per ha. The break-even time to pay back costs for the conversion of machinery for no-till seeding was two to three seasons. |

| The decision to fall or spring bed potatoes is often dictated by weather and processor contract agreements. Although there are advantages to both fall an( spring bedding, soil conditions are often wet in the spring in Malheur County, Oregon. Spring bedding of wet soils leads to soil compaction and decreased water infiltration. The primary objective of the study was to determine the effects of fall or spring bedding on tuber yields and quality under furrow irrigation. Determining the most effective method of fall potato ground preparation was the second objective of the trial. Land for potato production is normally moldboard plowed in the fall. Chisel plowing may provide better placement of residues in bedded ground and thus promote higher... |
