High K content can depress uptake of magnesium and may actually reduce yields on magnesium-deficient soils. So the unique balance of potash and magnesium that K-Mag provides is particularly beneficial to potatoes and other crops grown on light soils. Magnesium is the center of the chlorophyll molecule, the driving force for converting the sun's energy into a usable form by the plant. The nutrient increases plant strength and helps the plant withstand stress caused by insects and spray damage. Potatoes are notably susceptible to magnesium deficiency.
Sulfur aids initial growth and helps sustain vigorous growth throughout the season.
The nutrient also helps synthesize essential amino acids for plant proteins, which contributes to potato yield and quality. Along with magnesium, sulfur helps increase specific gravity and improves potato color, a critical factor for quality chipping potatoes. Higher yields remove even more, so to sustain high yields year after year, these essential nutrients must be replaced. Improve Your Crop And Profit Potential With K-Mag Individual nutrients perform best when properly teamed with other nutrients in a complete fertility program. It does not change the soil pH, even at high application rates.
