Potash or Potassium is macro or key nutrient required of plants. Fertilizer nutrients are represented as N-P-K on the label. Potassium promotes overall plant health, helps strengthen plants abilities to resist disease and plays an important role in increasing crop yields, quality and maximize fruit size. Potassium also protects the plant when the weather is cold or dry, strengthening its root system and preventing wilt. Straight potassium is great to use on legumes that produce their own nitrogen or areas where nitrogen leaching into ground water is a concern and phosphorus levels are sufficient.
