What is straight fertilizer? According to LBW Agro, Straight fertilizer is a fertilizer that contribute single nutrient to the crops. Few examples of straight fertilizer are urea, rock phosphate, ammonia, ammonium sulfate and muriate of potash.
Straight fertilizer can be used straight to the crops but the nutrients that have been supply are incomplete. This fertilizer usually mixed with other types of fertilizer to formulate mixed fertilizer and compound fertilizer. The advantage of this straight fertilizer is because of the low price compare to the other fertilizer. But, the effect to the crops is not good enough.
Types of Straight fertilizer
LBW Agro offer few types of straight fertilizer for plantation used such as palm oil, rubber, agar wood, paddy field and more. Straight fertilizer usually contributes one of these 3 main nutrients to the crops which are Nitrogen (N), Phosphorus (P) and Potassium (K) or mostly known as NPK.
- Nitrogen fertilizer – Nitrogen is one of the main elements which can be found in most commercial fertilizer. Nitrogen is important to the crops because nitrogen is a component in plant cells (chlorophyll) which gives the green look for the plants. Nitrogen function is to supply foods to the plant during photosynthesis and enhance the plants growth. Lack of nitrogen will cause the leaf become yellowish and consequence on the plant growth.
- Phosphorus (P) – Phosphorus is a second ingredient in fertilizer. It will act to enhance root growth and flowering. The root will grow deep and tree becomes much stronger. Nutrient will also be absorbed effectively by the roots.
- Potassium (K) – Potassium is also an important component in numerous fertilizers. It is important in flowering and fruiting purpose. Lack of potassium will have an effect on the plants protein synthesis. Potassium will support in plant chemical process such as carbohydrate, sugar, protein, and enzyme synthesis for plant growth.
- Magnesium fertilizer (Mgo) – Magnesium is an additional nutrient to plants besides the NPK. Magnesium is important in plants chlorophyll build up and protoplasm components. Depletion of magnesium will cause the plant leaf become yellowish and die.
What is compound fertilizer? Basically, a compound fertilizer is one that has several elements included or mixed like boron,copper,cobalt and many other elements that enhance the growing characteristics of a plant or tree.
