to Improve Soil quality
4 For example, the calculation for the use of wood ash as a material is as follows: Wood ashes (K2CO3) molecular weight = 138 CaCO3 = 100 100/138 = 0.72 (CCE) or 72% effective compared to CaCO3 So if a recommendation from a soil called for 1,000 lbs. of agricultural lime (CaCO3), then you would divide the CCE of 0.72 (K2CO3) into the rate needed to determine the

Soil Washing | Geoengineer
· Soil washing is an ex-situ remediation technique that removes hazardous contaminants from soil by washing the soil with a liquid (often with a chemical additive), scrubbing the soil, and then separating the clean soils from contaminated soil and washwater (US EPA 1993, 1996). The concept of soil washing is based on the theory that contaminants are prone to bind to fine grained soils (silts and ...
How to Select the Correct Washer Cycle for Clothes
· The four cycles are interchangeable and use medium-speed wash action, a low-speed spin, and a cool-down or rest period to reduce wrinkling. Normal: This cycle is for cotton or blended fabrics with average soil. The cycle combines high-speed wash action and high-speed spin, making it harsher on clothes.
Control Heavy Runoff
The following approaches to redirect and capture runoff can be used to control heavy runoff causing prolonged wet areas or yard erosion. If you have heavy runoff from roof downspouts and neighboring properties, redirecting or capturing runoff can provide better control. These techniques will minimize the amount of water that accumulates or that causes erosion in the problem area.
