Primary Nutrients
Primary Nutrients are chemical compounds that are applied to promote plant growth. Typically, fertilizers are applied to the soil. To make plants grow faster, the soil needs to be supplemented with nutrients in readily available forms. Most fertilizers supply just Nitrogen, Phosphorus and Potassium because other chemicals are needed in much lower quantities and are generally available in most soils. Nitrogen, Phosphorus and Potassium availability is the big limit to growth and these are called as Macro nutrients, which are more important to crops. They are classified as straight fertilizers, complex fertilizers and physical mixtures or granulated mixtures.

SPIC Ammonia (Agricultural Grade)
Ammonium Chloride fertilizer is manufactured by M/s. Tuticorin Alkali Chemicals and Fertilizers Ltd., and is marketed by Greenstar Fertilizer Ltd. Ammonium Chloride contains 25% Nitrogen. Besides nitrogen, Chlorine present in Ammonium Chloride improves root formation and ensures quality product output. The entire Nitrogen is present in Ammoniacal form.
SPECIFICATION
S. No. | Composition | Content (%) | |
---|---|---|---|
1. | Moisture percent by weight | Maximum | 2.0 |
2. | Ammoniacal nitrogen percent by weight, | Minimum | 25.0 |
3. | Chloride other than ammonium chloride (as NaCI) percent by weight | Maximum | 2.0 |
Features and Benefits
- Ammoniacal Nitrogen is not lost by leaching, since NH4+ is fixed by soil clay and humus complex. On application to the field, nitrogen will be released as and when the demand arises from the crop
- When ammonium Chloride is applied as basal or top dressing for cultivated crops, loss of nitrogen is very less. Consequently more N will be utilized by the crop, thereby fertilizer use efficiency is increased. Ammonium Chloride fertilizer application is recommended for saline and alkaline soils
- It is also a suitable Nitrogenous fertilizer for application in low-lying areas where paddy and other crops are cultivated by farmers. The chlorine present in Ammonium Chloride gives resistance to some pests and diseases
- Ammonium Chloride is less hygroscopic than other fertilizers which means the fertilizer has a fairly long life in storage. The chloride radical in Ammonium Chloride frees Phosphorous, Potash, Magnesium, Silica, Iron etc. from the soil
- Applying during the panicle initiation stage results in uniform maturity in paddy
RECOMMENDATION
- 50kg/ acre for paddy and all crops
