A test kit for professional scientists and non-scientists alike, the SIW-1 is for fertility analysis, site characterization, and irrigation water quality assessment under a wide variety of conditions. Farmer, Researchers, extension agents, and educators can use the versatile kit at remote sites, in the classroom, or even in areas lacking electricity. Kit utilizes dipstick, drop count, color disc and Pocket Pal Tester.
Soil tests include % Base Saturation (0-100%), Cation Exchange capacity (0-M meq/100g), Gypsum Requirement (0-360 kg/ha), Exchangeable calcium and Magnesium (0-M meq/100g), Lime Requirement (0-360 kg/ha), Nitrate-Nitrogen (0-60 ppm), pH (0-14 pH), Phosphorous (0-130 ppm), Potassium (0-250 ppm) and Total Exchangeable Acidity (0-M meq/100g). Test marked 0-M have no upper limit.
Irrigation water tests include Conductivity Calcium and Magnesium (0.2-4.0 mS/cm), Nitrate-Nitrogen (0-50 mg/L) pH (0-14 pH units) and Potassium (0-5 mg/L).
