Chalmers soils formed in loess and the underlying silt loam or loam till. Mean annual precipitation ranges from 813 to 965 mm (32 to 38 inches). Mean annual temperature ranges from 10.0 to 11.1 degrees C (50 to 52 degrees F).
The site was a 16.2 ha field of predominantly Chalmers silty clay loam (Fine-silty, mixed, superactive, mesic Typic Endoaquolls), with an initial pH of 6.4 and an OM content of 3.6%. Management Practices. Three tillage systems were selected for a wide range of soil management.

Tillage appeared to be the major contributor in the soil property changes with crop rotation effect being minor. Using soil erodibility as the baseline to develop a set of soil quality indicators, a standard scoring function enabled us to rate soil quality levels.
1 lut 1988 · The north-central location was established in 1975 on a Chalmers silty clay loam ( fine-silty, mixed mesic, Typic Haplaquoll). The soil is dark-colored, well-structured, naturally poorly drained and contains 59% silt, 32% clay and 4.0% organic matter in the Ap horizon.
The dry bare surface and subsurface Pewamo silty clay loam soils under CT and NT management with lower C/N ratios had relatively higher % reflectance between 350 and 2500 nm compared with NV. The dry subsurface Crosby Celina silt loam soils gave similar observations.
The soil was a deep silty-clay loam, with an organic matter content of 1.6% (0–30 cm). The cultivar Soissons was grown in 16 plots (8 preceding crops × 2 input levels). Preceding crops were faba bean, maize, pea, rapeseed, sorghum, soybean, sunflower, and wheat.
