What is DAP fertilizer?
DAP (Diammonium Phosphate) is one of the complex fertilizers widely used in agriculture thanks to its high nutritional content and outstanding efficiency. With an N:P2O5 ratio of 18:46, DAP fertilizer simultaneously provides two essential nutrients, nitrogen (Nitrogen) and phosphorus (Phosphate), helping plants grow strongly, with healthy roots and increased resistance to pests and diseases. DAP fertilizer is suitable for many types of crops, from rice, corn, to fruit trees and vegetables. Using DAP fertilizer properly not only increases productivity but also improves the quality of agricultural products, contributing to the sustainable development of the agricultural sector. Choose DAP fertilizer to ensure a bountiful harvest and protect the agricultural environment.

Uses of DAP 18-46 fertilizer
- Providing nutrients: DAP 18-46 fertilizer is an effective source of Nitrogen and Phosphorus for plants. Nitrogen helps promote the growth of leaves and branches and provides energy for the production of ATP – the main source of energy for plants. Phosphorus is an important nutrient in the process of absorbing and transporting energy, while promoting the development of the root system and fruits.
- Enhance growth and development: The combination of Nitrogen and Phosphorus in DAP 18-46 fertilizer provides the necessary elements to promote the growth and development of crops. It helps crops develop green leaves, strong tubers and large fruits, while enhancing their resistance to harsh environmental conditions.
- Improved crop quality: DAP 18-46 can improve crop quality by increasing nitrogen concentration in plants. This can increase yield and quality of the final product, meet market demand and increase farmer income.
Instructions for using DAP fertilizer for rice and crops
DAP (Diammonium Phosphate) is a complex fertilizer that provides both nitrogen and phosphorus, which is very effective in promoting plant growth. Here is how to use DAP fertilizer for rice and other crops:
Using DAP fertilizer for rice
Land preparation stage
– Dosage: 50-100 kg/ha.
– How to fertilize: Apply base fertilizer before planting, mix DAP fertilizer evenly into the soil. This helps provide nutrients from the beginning, creating favorable conditions for root development and healthy seedlings.
Branching stage
– Dosage: 30-50 kg/ha.
– How to fertilize: Apply the first top dressing when the rice begins to tiller. Spread DAP fertilizer evenly on the field, then water to dissolve the fertilizer and soak it into the soil.
Pre-flowering stage
– Dosage: 20-30 kg/ha.
– How to fertilize: Apply the second top dressing when the rice is about to flower. This helps the rice grow quickly, increases resistance and grain yield.
Use DAP fertilizer for other crops
Vegetable plants
– Dosage: 20-30 kg/ha.
– How to fertilize: Apply base fertilizer before planting, mix DAP fertilizer evenly into the soil. Apply top dressing after the young plants are a few weeks old to promote plant growth.
Fruit trees
– Dosage: 200-300 g/tree (depending on the type of tree and age of the tree).
– How to fertilize: Apply base fertilizer to the planting hole before planting. Apply top dressing at important stages such as flowering, fruit setting and after harvest to help the tree recover and prepare for the next crop.
Industrial crops (Coffee, Rubber, Pepper)
– Dosage: 100-200 kg/ha.
– How to fertilize: Apply as basal fertilizer before planting and top dressing during the main growth stages such as when the tree sprouts new leaves, flowers and fruits.
Notes when using DAP fertilizer
– DAP fertilizer should be stored in a cool, dry place to avoid mold.
– Do not over-fertilize to avoid burning roots and polluting the environment.
– Combine with other fertilizers (such as potassium fertilizer, organic fertilizer) to provide all the necessary nutrients for plants.
– Water thoroughly after fertilizing so that the fertilizer can easily dissolve and penetrate the soil, helping plants absorb better.
– Using DAP fertilizer properly will help plants grow strongly, increase productivity and quality of agricultural products, and contribute to protecting the sustainable agricultural environment.
