A useful soil result starts with a representative sample. Collecting, preparing, and reading that sample all matter when you want information you can use on your farm.
Start with the sample
Follow the sampling and preparation instructions for the test. Keep sampling depth and preparation consistent when comparing results, and keep clearly different areas separate.
Prepare. Separate. Analyze.
ASAD combines a miniature stirrer, centrifuge, and optical analyzer in one portable case. Prepare the sample, separate the testing solution, and take a sensor-based reading directly in the field.
Four readings. A fuller picture.
ASAD accurately measures nitrogen, phosphorus, potassium, and pH, with results comparable in accuracy to soil laboratory results. The ASAD apps for iOS and Android put those results on your own phone.
Read our guides to nitrogen, phosphorus, potassium, and pH to understand how each reading fits the bigger picture.
