Publication Type: Book / Chapter Publication Acceptance Date: 7/9/1998 Publication Date: N/A Citation: N/A Interpretive Summary: Techniques available for improving soil and water conservation fall into two broad categories: structure or landscape modification or management of soil surfaces and crop residues. This Chapter addresses the second category where tillage, residue management, surface roughness, and crop rotation are used for conservation in viable agricultural systems. This Chapter, organized by similar agricultural management systems, presents general principles used to develop management practices for production systems in the intermountain dryland areas of the Pacific Northwest. A number of conclusions and research needs are discussed, including needs pertaining to effects of burning straw on erosion, straw mulch compared to dust mulch, and pest and weed control. Technical Abstract: Techniques available for improving soil and water conservation fall into two broad categories: structure or landscape modification and management of soil surfaces and crop residues. This Chapter addresses the second category where tillage, residue management, surface roughness, and crop rotation are used for soil and water conservation in viable agricultural systems. This Chapter, organized by similar agricultural management systems, presents general principles used to develop management practices for production systems in the intermountain dryland areas of the Pacific Northwest. Advantages, limitations and research needs of management systems are reviewed, including crop residue management alternatives to winter cereals, weed and disease control, and crop rotations. The implications of management systems on long-term effects on soil properties, especially soil organic matter, are discussed. |
