Pro-Germinator, through proprietary manufacturing technology, contains both ortho-phosphate and carbon- protected polymer phosphate to provide both readily available and controlled-release phosphorus with minimal danger of tie-up in the soil. This controlled release of nutrients provides needed nutrients at planting, hook stage, tuber initiation, and on through flowering and bulking. Pro-Germinator is used primarily for the application of phosphorus but also includes nitrogen, potassium and micronutrients for maximum performance. Kalibrate Potatoes use more potassium than any other nutrient. Potassium is required for nutrient movement in the potato plant. It is essential for the makeup of over 40 different enzymes and is involved in more than 60 different enzyme systems in plants. Potassium is also important in the formation of sugars and starches in plants. In potatoes, potassium influences tuber size, specific gravity, blackspot bruise susceptibility, after-cooking darkening, sugar content, fry color and storage quality. Kalibrate is a highly efficient carbon-chelated liquid potassium that, when applied at planting or side-dress, is taken up from the soil along the length of young, fibrous roots. Potassium is transported in all directions among plant organs in response to metabolic demand. Kalibrate also contains 6 percent sulfur, another essential nutrient for potatoes.
