Measure soil infiltration
Time repeated ring trials and calculate surface infiltration rate in millimetres per hour and inches per hour.
Limit: One location and time does not diagnose drainage or site suitability.

Use simple measurements and calculations for soil, raised beds, rainfall and garden water. Choose metric or U.S. units where supported, keep the method and limits beside the result, and print or save only when you choose.

Start the soil infiltration testEnter inside dimensions and fill depth to calculate volume and whole containers.
Limit: Geometry does not determine soil quality, crop suitability, weight or settling.
Calculate raised-bed soilTime a known container fill and calculate litres per minute and U.S. gallons per minute.
Limit: The result describes the tested setup and does not determine pressure or plant water need.
Measure garden water flowConvert an entered rain-gauge depth over an entered area into litres and U.S. gallons.
Limit: Geometric volume is not captured runoff, soil moisture or plant-available water.
Calculate rainfall volumeConvert an entered volume over an entered area into millimetres and inches.
Limit: Equivalent depth does not prove even coverage, infiltration or whether watering is needed.
Calculate applied water depthThese tools use values you enter. They do not connect to weather, location or product data.
Compare entered flow, runtime, area, rainfall and an optional separate observation while keeping each evidence basis visible.
Limit: The calculation does not decide whether, when or how much to water.
Open the water application calculatorCalculate total rated emitter output and runtime volume from entered equipment values.
Limit: A product rating is not a field measurement and does not prove even delivery.
Calculate drip outputEstimate ingredient amounts and keep a printable record of the batch you plan or build.
Limit: A batch estimate does not promise compost quality, safety, certification or crop response.
Build a compost batchUse the Garden Planner, Garden Measurement Record, Garden Problem Observation Record or My Garden Evidence when you want to preserve what you observed.
A record preserves what you entered; it does not diagnose a cause or recommend a treatment.
TerraEvidence provides measurement, calculation and recordkeeping tools. For official Philippine agriculture programs, planting calendars, weather information or local requirements, use the responsible Philippine agency or local authority.
