The equivalent depth of water in the soil is 270 mm and the volumetric water content of soil is 5625 cubic meter/ 1.5 hectare of soil.
<h3>How can equivalent depth of water in a soil be calculate?</h3>
The equivalent depth of water in a soil is calculated using the formula below:
- equivalent depth of water = water content × depth of soil
The depth of soil profile 1 = 1 m = 1000 mm
The depth of soil profile 2 = 600 mm
Equivalent depth of water in the soil = 15% × 1000 mm + 20% × 600 mm
Equivalent depth of water in the soil = 150 mm + 120 mm
Equivalent depth of water in the soil = 270 mm of water
The volumetric water content of the soil is calculated using the formula below:
- Volumetric water content = water content × bulk density of soil/density of water × height of soil
Height of soil profile 1 = 1 m
Height of soil profile 2 = 0.6 m
Volumetric water content of soil profile 1 = 15% × 1300/1000 × 1 m = 0.195 cubic meter/square metre of soil
Volumetric water content of soil profile 1 = 20% × 1500/1000 × 0.6 m = 0.18 cubic meter/square metre of soil
Total Volumetric water content of soil = 0.18 + 0.195 = 0.375 cubic meter/square metre of soil
Converting to cubic meter/hectare of soil:
0.375 cubic meter/square metre of soil
1.5 hectares = 15000 square metre
Volumetric water content of soil = 0.375 × 15000 cubic meter/ 1.5 hectare of soil
Volumetric water content of soil = 5625 cubic meter/ 1.5 hectare of soil
Therefore, the equivalent depth of water in the soil is 270 mm of water and the volumetric water content of soil is 5625 cubic meter/ 1.5 hectare of soil.
