Coconut sabur contains high potassium which is beneficial for plants in producing better farming products in terms of quality and quantity.
Coconut coir contains the element potassium (K) that plants need. Apart from being a natural source of potassium (K), coconut coir contains other nutrients that are beneficial to plants. The nutrient content includes phosphorus (P), calcium (Ca), magnesium (Mg), sodium and several other micro elements. The element potassium (K) is more dominant, therefore POC coconut coir is a natural source of potassium fertilizer.
The benefits of coconut coir solution which has become Liquid Organic Fertilizer are numerous, including: 1. Strengthens plant stems and roots, 2. Increases the weight or content of fruit and plant seeds, 3. Brightens the color of fruit or plant seeds, 4. Adds fragrance on fruit, 5. The fruit becomes sweeter.
