As an essential nutrient for plant growth, Potassium availability is critical for optimal plant growth. Many US soils with adequate organic matter can supply some, if not all potassium for crop production. Although when soil K supply is less than optimal, an organic liquid potassium fertilizer program is required, with no better alternative than Pro K™ 0-0-20.
Pro K™ is a 20%, fully soluble liquid organic potassium fertilizer for crop production. With the lowest published application rates with all crops and most soil conditions, Pro K™ is the highest efficiency potassium and is approved for organic use in over 40 states across the US.
