Product Description

SoilDoc is a portable, on-site soil testing kit that is used to run soil analysis to provide tailored fertilizer and organic input recommendations for farms. The SoilDoc uses battery-powered instruments to test soil pH, biologically active soil organic matter, electrical conductivity, and micronutrients such as nitrate, sulfate, phosphate, and potassium. The kit transmits soil information via SMS (text message), allowing extension workers to make on-the-spot diagnoses of soil constraints and provide advice to farmers. This product is in a prototype phase.

Design Specifications

SoilDoc Kit is a mini-lab kit for analyzing soil samples to assess soil quality and make recommendations on what farmers can do to improve the soil condition of their farms. The soil fertility parameters analyzed with the SoilDoc field kit include soil pH, biologically active soil organic matter, electrical conductivity (indicative of general fertility levels and salinity issues), and 0.01 M calcium chloride extractable nitrate-N, sulfate-S, phosphate-P, and potassium-K. It has the capability to test nutrients in sap of growing crops for a snapshot of crop nutrients regarding nitrogen, phosphorus, sulfur, potassium. The kit also includes tools to measure soil physical properties like surface sealing strength, compaction and volumetric soil water content.
