Choosing the right fertilizer is the key to a bumper crop harvest, Compound fertilizer NP 8-40 shows strong support in agricultural production with its high phosphorus formula. Let’s take a look at its “agricultural superpowers” below.
1. Phosphorus: the core driving force of crop growth
Phosphorus is the “all-around assistant” of crop growth, and its function runs throughout the process:
Promote flower fruiting: activate flower bud differentiation, improve fruit setting rate, and change fruit trees from more flowering to more fruiting.
Strong roots and strong seedlings: Helps seedlings to deeply root their roots, which are 10-15 cm longer than ordinary seedlings, and significantly improves drought resistance and transplant survival rates.
Improve quality and life increase: participate in the synthesis of fruit sugar and amino acids, so that the sweetness of strawberries and other fruits can be increased by 1-2 points, and the shelf life will be extended by 2-3 days.
Resistance protection: Enhance the concentration of cell fluid. In disasters such as late spring cold, the frostbite rate in orchards is more than 30% lower than that in ordinary gardens.
2. Accurate application scenarios for high phosphorus formula
NP 8-40 (Nitrogen 8%, Phosphorus 40%) is a “nutrition plan” customized for specific needs, with outstanding results in the following scenarios:
(1) The key growth period of crops
Fruit tree flowering period to fruit setting period: the amount of phosphorus required for peach trees, lychee, etc. at this time, and the application can reduce the fall of flowers and fruits.
After the vegetable seedling period to planting, the roots of tomatoes, peppers, etc. are mixed with water, and new roots will appear in 7-10 days, and the time for seedlings will be reduced by half.
During the period of swelling of the roots and tubers: 20 kilograms of potatoes and yams are applied per mu, the weight of a single potato increases by 15%-20%, and the deformed fruits are reduced.
(2) Specific soil conditions
Phosphorus deficiency soil: It is used to replenish phosphorus in southern red soil and northern sandy soil to achieve rapid results. In one quarter, the soil phosphorus level can go from “scarce” to “suitable”.
Acid soil: It can prevent phosphorus from being locked by iron and aluminum ions, and the crop absorption rate is 25% higher than that of ordinary phosphorus fertilizers.
(3) Avoid chlorine crops
Grapes, tobacco, strawberries, etc. are sensitive to chlorine, and chlorine-free NP 8-40 is their “safe phosphorus supplementation option”.
3. Cooperative fertilization: Amplify the advantages of high phosphorus
NP 8-40 does not contain potassium, and the effect is better when used:
Fruit expansion period: “NP 8-40 + potassium sulfate + rotten peanut bran” can improve the quality of the fruit.
Cotton bud boll period: 15 kg NP 8-40 per mu is equipped with 5 kg potassium chloride to reduce bud fall and increase the fullness of the cotton boll.
| Fertilization combination | Sweetness | Colour and lustre | Hardness |
| Single NP 8-40 | 9.0% | Shallow | medium |
| NP 8-40+potassium sulfate | 9.5% | Deeper | higher |
| NP 8-40+potassium sulfate+decomposed peanut bran | 10.2% | Strong | high |
Note: Do not mix with alkaline fertilizers such as wood ash, with a spacing of 5-7 days; after sprinkling, cover the soil and water it to help the phosphorus be absorbed by the root system.
4. Conclusion
Compound fertilizer NP 8-40’s high phosphorus formula is a “timely rain” during the critical period of phosphorus required by crops. Scientifically used can make 40% of the phosphorus element a “harvest code”. You might as well try its effect during planting.
