The weight of an acre furrow slice is often assumed to be 2,000,000 lb for purposes of calculating storage capacity or required amounts of soil amendments. Similarly, a hectare furrow slice is sometimes assumed to weigh 2,000,000 kg.
What is furrow slice of soil?
Hectare-furrow slice (HFS) is the assumed mass of a hectare to depth of 15 cm, 2200 Mg (metric ton, 1000 kg. Acre-furrow slice (AFS) is the assumed mass of an acre to depth of 6 in, 1000 tons (2000 lbs). Pore Space. Can be calculated from known PD and BD.
How many tons of soil is an acre?
1 acre-foot of soil = 2,000 tons (approximate @ 92 lbs/cu. ft.)
How many furrows are in an acre?
Four lands, or forty rounds (80 furrows) measured 16.5 x 4 = 66 feet across by 1/8 mile (660 feet) long and was considered a good days work with a walking plow. The area plowed was therefore 43,560 square feet and became the standard unit of land area we call an acre.
How much does an acre of land weigh?
Acre (soil weight)
| Area | Furrow Slice | |

What is back furrow?
In agricultural technology: Primary tillage equipment. The ridge is called a back furrow. When two strips of land are finished, the last furrows cut leave a trench about twice the width of one bottom, called a dead furrow. When land is broken by continuous lapping of furrows, it is called flat broken.
What is the weight of 1 hectare soil in KG?
2 million kgs
Generally, 1 ha soil with 15 cm depth is equal to 2 million kgs. For converting g/kg into kg/ha, you should be aware of the bulk density or the depth to get the final soil volume.
How much is top soil per acre?
There are 43,560 square feet in an acre so there are 4,356,000 square feet in 10 acres. At a depth of 2 feet this gives you a volume of topsoil of 8,712,000 cubic feet.
How long does it take to walk an acre?
A square acre is 208.7 feet on a side, so the perimeter of an acre is about 835 feet, or about 16 percent of a mile. If you walk a brisk pace of 3 miles an hour, you can cover a mile in 20 minutes. So you should be able to walk 835 feet in about three minutes.
How long does it take to plow an acre?
Constraints when using a tractor to plow one acre: A tractor needs 1 hour to plow an acre. The tractor can be hired for 8 hours per day. Ten person-hours of family labor are needed for clearing, preparation, and planting of each acre. The plowing is done twice, the first time for clearing, the second time for planting.
How do you calculate an acre inch of water?
Conversion Formulas The following formulas are handy for computing the approximate depth of water applied to a field. Cubic feet per second x hours acres = acre-inches per acre, or average depth in inches. Gallons per minute x hours 450 x acres = acre-inches per acre, or average depth in inches.
How many gallons of water does it take to cover 1 acre?
27,154 gallons
Acre-inch (ac-in) One acre-inch is the volume of water necessary to cover an acre 1 inch deep or the amount of water falling on an acre in a 1-inch rain. One acre-inch equals 3,630 cubic feet or 27,154 gallons.
How does an acre furrow slice of soil work?
The typical soil volume used in acre furrow slice calculations is 24,394 cubic feet, and is determined by multiplying the number of square feet in an acre (43,560) by a depth of 0.56 feet (6.7 inches ÷ 12 inches = 0.56 feet). Determining the weight of soil in an acre furrow slice involves knowing the dry bulk density of the soil in question.
How to calculate the weight of soil per acre?
To determine the weight of dry soil in an acre furrow slice, multiply 82.99 pounds by 24,394 cubic feet for a total weight of 2,024,458 pounds. Typically, this number is rounded off to 2,000,000 pounds of soil per acre furrow slice.
How much does one cubic foot of dry soil weigh?
By multiplying 1.33 grams/cubic centimeter by a conversion factor of 62.4, you can determine there are 82.99 pounds of dry soil in one cubic foot. To determine the weight of dry soil in an acre furrow slice, multiply 82.99 pounds by 24,394 cubic feet for a total weight of 2,024,458 pounds.
How many deciSiemens are in a millimhos of soil?
millimhos per centimeter (mmho/cm) = a measure of the electrical conductivity of the soil mmho/cm = 1 decisiemens per meter (dS/m)
