Interprets the soil analysis by horizon, including sand mulch. Diagnoses salinity, sodicity, acidity and fertility, sets the order of correction and passes the problems to correct on to Soil amendments.
Entry by horizon, sand mulch, texture, exchange complex and extract with consistency check.
Features
- Horizons and sand mulch: Several depths from the same point and date; sand mulch with thickness, sand type and years since renewal.
- Texture and exchange complex: Calculated texture class, CEC and exchangeable cations in mg/100 g, meq/100 g, cmol(+)/kg or mg/kg.
- Extract and fertility: Extract pH and EC with the extraction ratio, ions, Olsen or extract phosphorus, nitrate, ammonium and micronutrients.
- Diagnosis: Soil status, priorities, interpretation of each parameter with its thresholds and interpretation limits of the sample.
- Irrigation water and history: Soil predicted by the irrigation water for a given dose and depth, plot time series and horizon profile.
- Correction: Problems to correct and data passed to Soil amendments to choose product and rate.
- Compare: Comparison of two analyses or of up to four selected samples.
Inputs
Analysis by horizon: texture, organic matter, carbonates, CEC and exchangeable cations. Extract pH and EC, extract ions, phosphorus, mineral nitrogen and micronutrients. Laboratory methods, sampling date and depth, irrigation and sensor readings.
Results
Soil status, conclusion by problem and diagnosis priorities. Recommendations and phased action plan. Soil predicted by the irrigation water, time series, horizon profile and analysis quality.
Calculation conditions
The diagnosis interprets the sample delivered; its representativeness depends on field sampling. Saturated paste extract and 1:5 extract use different scales, and each analysis states its extraction ratio. Rate, cost and schedule of each amendment are calculated in Soil amendments.
