Characteristics and Functions of Nitrate-Sulfur Composite Fertilizer
This article focuses on the introduction of the characteristics and functions of nitrate-sulfur composite fertilizer in the field of green plants and flowers, with specific details as follows:
Characteristics and Functions of Nitrate-Sulfur Composite Fertilizer
Nitrate-sulfur composite fertilizer has the characteristics of quick effect and short fertilizer duration, and is often used on garlic. However, the timing of its application on garlic is very crucial. It is important to note that nitrate-sulfur cannot be used as a base fertilizer for garlic, as its quick effect can easily cause garlic to grow vigorously before winter, leading to a decrease in its ability to resist frost damage.
Nitrate-sulfur composite fertilizer refers to a type of fertilizer where nitrogen is provided by ammonium nitrate, potassium is sourced from sulfate of potash, or potassium chloride is treated to remove chlorine ions.
This type of composite fertilizer does not contain biuret, and the chlorine ion content is below 3%. What are the characteristics of nitrate-sulfur composite fertilizer? What functions can it perform?
Characteristics of Nitrate-Sulfur Composite Fertilizer
1. Fast and efficient action
Nitrate-sulfur composite fertilizer is rich in nitrate nitrogen, which dissolves quickly after application, allowing the nitrogen nutrient to be absorbed directly by the crop, resulting in fast and noticeable fertilizer effects and high fertilizer utilization efficiency.
2. Completely water-soluble
Nitrate-sulfur composite fertilizer dissolves quickly without leaving residue, and the release of nutrients is more uniform, effectively improving fertilizer utilization.
3. Pure sulfate of potash
When applied to sulfur-loving crops such as legumes, onions, grapes, tomatoes, nitrate-sulfur composite fertilizer can significantly increase the content of protein, vitamin C, and improve the quality and flavor of agricultural products.
This type of fertilizer is especially suitable for chlorine-sensitive economic crops like tobacco, and is a preferred fertilizer for sulfur-loving crops, chlorine-sensitive crops, and alkaline soils.
4. Promotes root growth and fruit setting
Nitrate-sulfur composite fertilizer can coordinate soil nutrients (G-Y), improve the growth environment of crops, enhance root vitality, promote root development, and strengthen the plant's drought and disease resistance.
Advantages of Nitrate-Sulfur Composite Fertilizer
1. Dry field crops
Nitrate-sulfur composite fertilizer is suitable for dry field crops, especially for sulfur-loving and chlorine-sensitive crops or soils deficient in sulfur and alkaline. It does not cause residual pollution.
2. Meets the needs of crops at different stages
As a base or top-dressing fertilizer, it can meet the different nutrient needs of crops at different growth stages, improving their resistance to diseases and lodging.
3. Rapid effect
Compared to other traditional composite fertilizers, nitrate-sulfur composite fertilizer contains higher nitrogen and potassium, has a reasonable formula, strong solubility, and rapid fertilizer effect, which is beneficial for the absorption of phosphorus, potassium, and other nutrients by the crop.
Therefore, it has high fertilizer utilization efficiency, avoids or reduces the accumulation of nitrites in plants, and is a high-quality, efficient, eco-friendly, and non-polluting new type of composite fertilizer.
4. Long-lasting effect
The fertilizer effect of nitrate-sulfur composite fertilizer lasts for about 90 days, making it a high-quality, efficient, eco-friendly, and non-polluting new type of composite fertilizer.
Suitable Crops for Nitrate-Sulfur Composite Fertilizer
1. Economic crops
Nitrate-sulfur composite fertilizer is usually suitable for high economic value crops such as fruits and vegetables, especially for sulfur-loving and chlorine-sensitive crops or soils deficient in sulfur and alkaline. Using nitrate-sulfur composite fertilizer as a top-dressing has a fast release of fertilizer effect and is beneficial for the growth and expansion of fruits and vegetables. The sulfur element in it also helps to improve the quality of these crops.
2. Grain crops
Compared to potassium chloride, nitrate-sulfur composite fertilizer is more expensive and is generally not used on grain crops, but mainly on economic crops such as vegetables and fruit trees, which have better economic benefits.
3. Sulfur-loving crops
Both nitrate-sulfur fertilizer and sulfate of potash fertilizer can provide potassium fertilizer for crops, and have a significant yield-increasing effect on sulfur-loving crops such as tobacco, tea trees, fruit trees, potatoes, beets, cruciferous vegetables, onions, and garlic.
4. Chlorine-sensitive crops
Nitrate-sulfur composite fertilizer applied to chlorine-sensitive crops such as tea trees, grapes, peaches, apples, tobacco, potatoes, sweet potatoes, beets, oranges, sugarcane, watermelons, lettuce, amaranth, cabbage, peppers, eggplants, and tomatoes can significantly improve quality and promote growth and development.
