What is Nitrophos?
Sarsabz Nitrophos (NP) is a granulated fertilizer in which each grain has equal
amounts of Phosphorus (P) 20% & Nitrogen (N) 22%. In addition to this, NP being
a highly acidic product with a pH of 3.5 is the most suitable one.
Production:
The majority of commercial phosphorus (P) fertilizer is made by reacting raw
phosphate rock with sulfuric or phosphoric acid. The sulfuric acid method of
producing P fertilizer results in large amounts of calcium sulfate (gypsum)
byproduct that incurs additional disposal costs.
Nitro phosphate production of P fertilizer differs because it involves reacting
phosphate rock with nitric acid, which is made by oxidizing ammonia with air at
high temperatures. A primary advantage of this method is that little or no sulfur (S)
inputs are required. With the nitro phosphate process, excess calcium from the
phosphate rock converts to valuable calcium nitrate fertilizer instead of gypsum.
Norway pioneered the nitro phosphate method, and much of the global production
still occurs in Europe.
The general reaction is:
Phosphate rock + Nitric acid à Phosphoric acid + Calcium nitrate + Hydrofluoric
acid.
Manufacturers often mix the resulting phosphoric acid with other nutrients to form
compound fertilizers containing several nutrients in a single pellet. They sell the
cogenerated calcium nitrate or calcium ammonium nitrate separately as
independent products.

Management practices:
Nitro phosphate fertilizer contains varying amounts of ammonium nitrate, which
attracts moisture. To prevent clumping or caking, manufacturers generally pack it
in water-tight bags to protect it from moisture before delivery to the farmer.
Applications:
Nitro phosphate fertilizers can contain a wide range of nutrients, depending
on their intended use. Its important growers select the proper composition
for each specific crop and soil requirement. The granular form goes directly
on the soil’s surface. It’s also commonly mixed within the root zone or
applied as a concentrated band beneath the soil surface prior to planting.
The balanced combination of Nitrogen & Phosphorus is ideal for plant
growth and development. It contains dual Nitrogen (Nitrate: readily
available to the plants and Ammonical: available after its conversion to
nitrate through the process of nitrification). Consistent and longer use of
Sarsabz NP also improves soil health.
Sarsabz Nitrophos (NP) can be applied universally on all types of soils, but
is more effective where the soils have high pH and are alkaline in nature. In
many crops it could be effectively applied at planting and at early growth
stages of the crops. Each grain has equal amounts of N & P; hence the
nutrient is equally divided.

What is Zinc Sulphate?
Zinc sulfate is a combination of sulfur and zinc. It is an herbicide typically
used for moss control. The toxicity of zinc sulfate depends on the amount of
zinc in the product. Zinc is an essential mineral for human, animal, and plant
nutrition. Zinc can be found naturally in the environment, foods, and water.
Products that contain zinc have been registered for use in pesticide products in
the United States since 1973.
Production:
Zinc sulfate is produced by treating virtually any zinc-containing material (metal,
minerals, and oxides) with sulfuric acid.

With a reduction potential of -0.76, zinc (II) reduces only with difficulty.
When heated above 680 °C, zinc sulfate decomposes into sulfur dioxide gas
and zinc oxide fume, both of which are hazardous.

Applications:
Zinc Sulfate 35.5% Monohydrate Maxi-granular is a dry amendment which
can be applied directly to the soil. It can be mixed with other dry
amendments such as humates, and other dry fertilizers. The rate applied
depends on results of soil analysis.
Zinc Sulfate 35.5% can also be dissolved and added to foliar solutions.
Application can be as often as every other week, depending on results of
tissue analysis.
Zinc sulfate is also used to supply zinc in animal feeds, fertilizers, and
agricultural sprays. Zinc sulfate, like many zinc compounds, can be used to
control moss growth on roofs.
Furthermore it can be used as in electrolytes for zinc plating, as amordant in
dyeing, as a preservative for skins and leather and in medicine as an
astringent and emetic.
If the crop is lack of this micronutrient it will terminal growth long and
slender with few lateral buds; Chlorosis pronounced at the base of the leaf.
Crinkling and reddening of leaf edges possible.
