the widest spread of a particular species. The volume of soil required is equal to displayed value. 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. The consistency limit was determined by Atterberg an Agronomist for the first time, Therefore this is also known as Atterberg’s limit. Cubic Yard Calculator. If the average depth is 12'; the slope must extend 75% outward from the beginning of where the 12' begins. This calculator can be used for top soil, mulch etc. Remember that obtained result … For example, if the weight of the soil is now 1 lb. Example: Calculate the CYs of Dirt to be removed from an excavation that is 20' by 35'. A cubic yard is equal to 27 cubic feet. Before calculation, you must have good knowledge of the consistency of soil. Divide the weight of the dry soil by the volume of sand required to fill the hole to find the soil density in pounds per cubic foot. 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. Please note, this formula does not apply to fastigiated and columnar habit trees. As a general guide, 1 cubic yard of aggregate, sand, or dirt is equivalent to 1.5 tons. Circular π r 2 x Depth Circular areas are also easy to calculate. Soil moisture content calculation can be done using this Soil Moisture / Water Content formula. Topsoil calculator formula. The soil type is A. Non-plastic silts require about 10% cement, whereas plastic clays may need about 13% cement. Moisture content is the vital property of soil which is essential for the agriculture. Calculation Formulas Square or Rectangle (Length x Width x Depth) The area of a square or rectangular garden is easy to calculate. You can use the online calculator to determine how many cubic yards of material are required. The physical state of fine-grained soil at particular water content is known as its consistency. per cubic foot. The soil volume requirement can be calculated for narrow form trees by basing the canopy diameter on the natural growth form, i.e. (based on chart slope is 3/4:1) 75% of 12 = 8. It does this by using the formulae given below: Rectangular Garden Bed Soil with insufficient water content becomes unfit for cultivation. Raised Bed Soil Calculator We’ve seen far too many raised beds filled with “potting mix” from the landscape supply company with unhappy plants and unhappy gardeners. Topsoil Calculator Use this topsoil calculator to find out how much topsoil you need to buy for your yard. A well-graded soil requires about 5% cement, whereas a poorly graded, uniform sand may require about 9% of cement. The percentage of water contained in a soil is called as the soil moisture content. 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. 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 … We sell all of our online materials by the cubic yard.
