West Dakota Water Development District Looks To Improve Rapid Creek Water Quality Through Stormwater Mitigation and Erosion Control Projects

Two pilot projects initiated by the West Dakota Water Development District are intended to improve water quality in Rapid Creek by reducing suspended sediment loading over time.

Water Use by Plant Stage

Over the growing season, solar radiation, air temperature and plant size are the dominant factors in determining evaporative demand and the rate of water use by wheat. Water use can vary dramatically on a day-to day basis, depending on climate and wheat health.

Utilizing Cover Crops for Grazing: An Assessment on Economic Benefits

Grazing cover crops by cattle provides an option to offset cover crop seed costs and increase farm revenue. To facilitate farmers’ decision making, this article will evaluate the economic profitability from grazing cattle on cover crops using a partial budgeting approach.

Fall Tillage: Please Don’t Think About It

Conducting fall tillage results in lost topsoil, soil nutrients, and soil moisture. This ultimately leads to reduced soil productivity and profitability. An easy way to conserve topsoil and water resources is to skip fall tillage.

Five Range Management Principles: #3 Ecosystem Biodiversity

Milkweed can help make rangelands a better environment for both cattle and neighboring plants and animals by having a shielding effect on companion plants, preventing erosion and accelerating the decomposition process, whole also providing nectar, habitat and organic material for ecosystem services.

Farm Practices That Improve Soil Health: Cover Crops and Crop Residues

Planting cover crops and returning crop residues (stover) to the soil both adds nutrients and improves overall soil quality. These practices are common with producers across South Dakota and have been recently studied by researchers to identify how they impact the release of greenhouse gases into the atmosphere.
