Note in selection, storage and use of fertilizer

Provide sufficient and timely nutrients for plants to grow and develop well, high productivity and high quality of agricultural products.
Non-stop protection, enhance fertility fertility of soil, protect the living environment of microorganisms.
Bring economic efficiency and profit to create a high income, stable for the farmer.
Suitable for cultivation conditions, production methods, saving, avoiding waste, wasting fertilizer.
To use fertilizers effectively, improve productivity and quality of agricultural products, people should note and understand the characteristics of a number of factors as follows:
1. Nutritional requirements of plants
Each crop has a different nutritional and nutritional requirement. The nutritional requirements of the plant should be the first factor to consider for effective use of fertilizers. Based on the amount of substance that plants need to grow for high yield, stable that fertilizer application rate accordingly. The nutritional requirements of each crop depend on:
Crop characteristics: Each crop has a different nutritional requirement. Bulbs need more phosphorus and potassium, and the plants use more nitrogen. Perennial crops need more nutrients, fertilizer than the annual crops, and sugar crops, the demand for potassium fertilizer is high.
Characteristics of each variety: There are many varieties of the same variety, each with different nutritional needs. For example, the same species of maize, which has the same need for less fecal fertilizers, is more likely to produce higher yields than larger varieties of maize.
Characteristics of each stage of the plant: The seedling stage needs less nutrition. The development stage of the leafy foliage requires more phosphorus and protein, the period of raising the fruit needs more potassium, … the right time in each stage of the plant. For example, fertilizing the rice at the right time will help the rice in good health, copper, healthy. If the late application of rice will be a lack of nutrient distribution weak, small diminishes the yield of rice.
Crop yield: based on the amount of nutrients that crops follow harvested agricultural products. The higher the yield requirement, the more fertilizers are needed, the higher the yield, the greater the need for large amounts of nutrients to help the plant to flower, the percentage of fruiting and nutrient availability, Big fruit, grain weight.
2. Features of cultivated land
- Need to know what land belongs to their land group? Sour, salty, alum or alkaline, … To choose the type of fertilizer suitable for each land type.
- Based on the fertility and the amount of nutrients that the soil can provide to the plant. Fertile soil, fertile need less fertilizer than bad soil, color. With low fertility soils, hardwood land needs to be enhanced by using organic fertilizers that increase the amount of humus to improve soil fertility.
- Based on the pH to select the appropriate fertilizer, acid soil should use alkaline fertilizers and vice versa.
- Based on the mechanical components of the soil. Sand soil lack potassium should need to apply more potassium, poor water retention should be divided into several times to avoid application of washout to drain the fertilizer. The heavy mechanical soil should be enhanced using organic composted organic fertilizer, organic compost to improve and stabilize the structure, improve fertility, reduce pH, reduce acidity, …
