Crop residue management received little attention until about 1970. Records of crop residue
production are limited, but crop yield databases have been available since 1865. Carbon …

The central USA contains some of the most productive agricultural land of the world. Due to
the high proportion of land area committed to crops and pasture in this region, the carbon (C) …

Compactive processes affect soil hydraulic properties and associated soil water flow. Soil
water retention and transport properties are altered in response to changes in pore space …

Soil organic carbon (SOC) and nitrogen (N) are directly influenced by tillage, residue return
and N fertilization management practices. Soil samples for SOC and N analyses, obtained …

Seven crop residue treatments were initiated in 1931 to measure long‐term residue management
effects on soil organic matter in a wheat‐fallow cropping system on Pacific Northwest …

It is often necessary to measure soil water content at multiple points in space and time. Our
goal was to develop an automated and multiplexed measurement system using time‐domain …

Conservation production systems combine tillage and planting practices to reduce soil erosion
and loss of water from farmland. Successful conservation tillage practices depend on the …

Compaction of soil has become a problem of worldwide concern because of (1) larger tractors,
tillage, and harvesting equipment; (2) increases in intensive cropping practices; and (3) …

Soil organic carbon (SOC) is sensitive to management of tillage, residue (stover) harvest,
and N fertilization in corn (Zea mays L.), but little is known about associated root biomass …
