Interpretive Summary: The placement of crop residues has great importance for both natural resource assessment and analysis of experiments. Crop residue placement can be used to forecast infiltration, organic matter changes, nutrient pools, carbon accretion vs CO2 production, pesticide degradation and transport, and soil quality. Field trials in the Soil and Water Management Unit, St. Paul, have shown that crop residue placement on the surface and in the buried position is controlled by the tillage tool and their use in tillage systems. This knowledge base is especially useful for national assessments of natural resources by NRCS because the national surveys of tillage systems (used by farmers) can be precisely interpreted as to the crop residue placement. Placement controls many of the soil and water conservation, soil quality, and soil productivity benefits. Conservation planners often require this spatially integrated information.

Technical Abstract: The placement of crop residues has great importance for both experimentation analysis and natural resource assessment. A working knowledge of crop residue placement can be used to forecast infiltration, organic matter changes, nutrient pools, carbon accretion vs CO2 production, pesticide degradation and transport, and soil quality. Field trials in the Soil and Water Management Unit, St. Paul, have shown that crop residue placement on the surface and in the buried position is controlled by the tillage tool and their use in tillage systems. This knowledge base is especially useful for national assessments of natural resources because the national surveys of tillage systems (used by farmers) can be precisely interpreted as to the crop residue placement, and placement controls many of the soil and water conservation, soil quality, and soil productivity benefits.
