Soil Infiltration Rate Calculator
Soil Infiltration Rate requires one defined scenario. Measure infiltration from water depth and elapsed time. Use water depth infiltrated and elapsed time from the Soil Infiltration Rate record.
Enter values for infiltration rate
Read each Soil Infiltration Rate field note before calculating infiltration rate.
Water depth infiltrated and the other inputs
Prepare Water depth infiltrated and Elapsed time for Soil Infiltration Rate. Keep unrelated records separate.
Water depth infiltrated. The Soil Infiltration Rate assumption is 1.4 in; note the source of any replacement.
Elapsed time. Default in Soil Infiltration Rate: 45 min.
A practical check for water depth infiltrated
Take enough readings to see whether water depth infiltrated varies across the bed. A single convenient spot may not represent the root zone. The Sulfur Application Amount Calculator provides sulfur needed.
Soil Infiltration Rate in practical terms
The planning question for Soil Infiltration Rate is whether you can measure infiltration from water depth and elapsed time. Soil Infiltration Rate measures this portion as Infiltration rate.
Record adjustments outside Infiltration rate separately.
From water depth infiltrated to infiltration rate
Soil Infiltration Rate divides quantities drawn from Water depth infiltrated and Elapsed time.
Using water depth infiltrated at 1.4 in and elapsed time at 45 min, the example returns 0.031 in/min.
Using the Soil Infiltration Rate result
Use Infiltration rate to measure infiltration from water depth and elapsed time. Keep the Soil Infiltration Rate inputs beside the output. Need soil carbon stock? Open Soil Carbon Stock Calculator.
Soil Infiltration Rate beyond the formula
Initial dry-soil intake can be faster than the sustained rate.
A zero Elapsed time leaves infiltration rate undefined in Soil Infiltration Rate.
Soil Infiltration Rate record to keep
A reproducible Soil Infiltration Rate case includes Water depth infiltrated and Elapsed time and Infiltration rate.
Note the collection method for water depth infiltrated and preserve any unrounded source value.
When the outcome is known, compare it directly with infiltration rate on the saved basis.
Soil Infiltration Rate low-and-high comparison
Test Soil Infiltration Rate with Water depth infiltrated at 1.54 in rather than 1.4 in. The displayed infiltration rate becomes 0.034 in/min instead of 0.031 in/min.
The test holds elapsed time constant.
Test a measured range for water depth infiltrated when it may alter the decision.
Questions about Soil Infiltration Rate
Can Elapsed time be zero in Soil Infiltration Rate?
In Soil Infiltration Rate, zero elapsed time makes infiltration rate undefined.
