A comparison of soil properties and plant-to-plant variability in no-till and strip-till corn fields in Illinois
… matter, penetration resistance, bulk density, water aggregate stability, infiltration rate) that could be influencing the differences in root efficiencies and nutrient uptake observed under ST and ii) determine if variability differs between ST and NT for linear distance between plants, plant …

Quality Soil Management in Illinois Using Winter Cover Crops
… (P). Soil physical properties analyzed were water aggregate stability (WAS), bulk density (BD), penetration resistance (PR), total porosity (TP), pore size distribution, water retention properties, and saturated hydraulic conductivity (K sat). Compared to winter fallow, crop sequences that …

Soil quality in long-term corn and soybean rotations
… each year. We measured soil bulk density (BD), water aggregate stability (WAS), cation exchange capacity (CEC), soil organic matter (SOM), and plant-essential nutrients at the depths of 0-15, 15-30, 30-60, and 60-90 cm. Univariate and multivariate statistical analyses were conducted, including …

Tillage and cover cropping effects on soil properties and crop production
… soil attributes included bulk density (BD), water aggregate stability (WAS), and penetration resistance (PR), as well as chemical properties of soil organic matter (SOM), total carbon stocks (TCs), pH, plant available nitrogen (TIN, NO3-N and NH4-N), available phosphorus (P), and exchangeable …

Long-term effect of crop rotation and tillage on soil properties
… nitrogen (TN), and available phosphorus (P) and water aggregate stability (WAS) varied with treatment effects of rotation and tillage at Perry, but not at Monmouth, where soils had higher initial soil organic matter content. At Perry, TC, TN and P were greater at 0-10 cm depth under no-till, but …

Using cover crops to alleviate compaction in organic grain farms
… Penetration resistance (PR), bulk density (BD), water aggregate stability (WAS), total carbon (TC), nitrate (N-NO3), ammonia (N-NH4), bray phosphorus (P), and pH was determined each sampling time. Additionally, texture and Proctor determinations were conducted once at the beginning of the study. …

Residue, tillage, and nitrogen effects on soils
… with 268 kg N ha-1 applied had a pH of 4.72. Water aggregate stability (WAS) was only significantly impacted at Urbana, where no-till plots had 84% WAS while tilled plots had 81% WAS. Compared to soils with 134 kg N ha-1 applied, soils with 268 kg N ha-1 applied the previous year had higher …

Agronomic assessment of grazing method of corn residues on cow performance, residue utilization, crop yield, and soil properties
… was not affected (P = 0.56) by treatment. Water aggregate stability was decreased (P = 0.01) in CG and SG compared to CT. Soil nitrate was increased (P = 0.03) in CG compared to SG, with CT being intermediate. Soil ammonium was not affected (P = 0.14) by grazing treatment. Soil pH was …

Changes in soil properties and their effects on maize productivity following sesbania and pigeon pea improved fallow system in Eastern Zambia
… organic carbon, soil penetration resistance, water aggregate stability and distribution, infiltration rate and soil water current. The highest survival seasons were recorded in S. sesban (92%) while pigeonpea had only (31%). at the end of the 10-week incubation period, the N mineralization of …

Response of Soil Properties to 23-25 Years of Diverse Crop Rotations and Tillage Systems in South Dakota, USA
… (SOC), total nitrogen (TN), bulk density (ρb), water aggregate stability (1-2 mm), and light fractions of carbon (LFOC) and nitrogen (LFON). The physical-hydrological parameters include soil water infiltration (qs), water retention (SWR), pore-size distribution (PSD), bulk density, and …

Evaluating greenhouse gas emissions from Illinois agriculture systems
… by denitrification, thus contributing to both water and air pollution. Agricultural soil management accounts for much of the total N2O production in the US. Two of the most important agricultural practices aimed at improving soil properties and reducing inputs are crop rotations and no-tillage, …
