INDIVIDUAL TEST KITS
HUMUS Humus is organic matter which has decomposed to the point that it releases nutrients which are then available for plant uptake. |
Model No. | Method | Range & Sensitivity | Reagent System | # of Tests |
ITK-5012 | ColoRuler, filtered extraction | Low to high in 5 increments, 1 1/2-8% | EDTA | 50 |
R-ITK-5012 | Reagent refill kit |
pH The pH value affects all mineral elements and the biological processes that can be performed by plants in the soil. Accurate pH testing is essential to determine lime requirements and to insure that a mineral-rich soil is also fertile. |
Model No. | Method | Range & Sensitivity | Reagent System | # of Tests |
ITK-5024 | Colour chart & spot plate | pH 4.0, 5.0, 6.0, 7.0, 8.0 | Duplex Indicator | 100 |
R-ITK-5024 | Reagent refill kit |
PHOSPHORUS Phosphorus stimulates early root formation, gives a vigorous start to plants, hastens maturity, stimulates blooming and aids in seed formation. Symptoms of deficiency include stunted growth, leaf abnormalities, and even dead areas. Available nitrogen and soil pH in the range of 6.0-7.0 provide optimal conditions for the uptake of phosphorus. |
