Landscape supply mixes are often high in salts and high in pH and completely unbalanced in nutrients. As a general guide, 1 cubic yard of aggregate, sand, or dirt is equivalent to 1.5 tons. The soil type is A. A cubic yard is equal to 27 cubic feet. If the average depth is 12'; the slope must extend 75% outward from the beginning of where the 12' begins. The soil volume requirement can be calculated for narrow form trees by basing the canopy diameter on the natural growth form, i.e. Soil with insufficient water content becomes unfit for cultivation. and the volume of the sand in the hole is .5 cubic feet, the density would be 1 lb/.05 cubic feet, or 2 lbs. The volume of soil required is equal to displayed value. (based on chart slope is 3/4:1) 75% of 12 = 8. For example, if the weight of the soil is now 1 lb. It does this by using the formulae given below: Rectangular Garden Bed Before calculation, you must have good knowledge of the consistency of soil. Remember that obtained result … Landscaping Calculator: Determine the number of "yards" needed based on length, width and depth that you need. Example: Calculate the CYs of Dirt to be removed from an excavation that is 20' by 35'. Simply multiply the length by the width by the depth or use our simple volume calculator. Using the measurements you provide from your lawn, our calculator first works out the area and volume of the soil required to ensure equal topdressing coverage. 2/15/2009 Page 5 of 23 ce-ref.com Example 3: Circular footing on sandy clay Given: • Soil properties: • Soil type: sandy clay • Cohesion: 500 lbs/ft2 • Friction Angle: 25 degree • Unit weight of soil: 100 lbs/ft3 • Expected footing dimensions: • 10 ft diameter circular footing for a … This calculator can be used for top soil, mulch etc. Soil moisture content calculation can be done using this Soil Moisture / Water Content formula. You can use the online calculator to determine how many cubic yards of material are required. A well-graded soil requires about 5% cement, whereas a poorly graded, uniform sand may require about 9% of cement. Moisture content is the vital property of soil which is essential for the agriculture. per cubic foot. Please note, this formula does not apply to fastigiated and columnar habit trees. Calculation Formulas Square or Rectangle (Length x Width x Depth) The area of a square or rectangular garden is easy to calculate. Non-plastic silts require about 10% cement, whereas plastic clays may need about 13% cement. Our calculator is a flexible tool, so you can calculate everything the other way round: if you have a bag of soil and size of your containers, you can estimate how many pots can be filled.
