-
General
- About 40% saving of manure expenses due to lower product cost and fully mechanized loading and unloading , transporting and storing activities.
- Utilization of 1,5 times more weight units nitrogen due to the lower losses of evaporations and higher relative weight of the Liquid fertilizer.
- More evenly and worth spreading distribution and faster effect from fertilizing.
- Insignificant losses of nitrogen evaporation even in case of absence of optimum humidity.
- Maximum use of the active substance even at higher temperatures without need of digging.
- Product's neutrality to the soil oxidation. Carbamide ammonificates to Ammonia Carbamide in contact with the urobacteria in soil causing alkali reaction and neutralizing the nitrate nitrogen acid reaction.
- Guaranteed safety in use - urea is neither fire, nor toxic or explosion hazardous.
- The product preserves its qualities independently of the storage period.
- In case of combined application with herbicides the farmer may save up to 20% of the herbicide without using adhesives. The mixture of Liquid nitric fertilizer and herbicides is of low level fitotoxidity and may be applied throughout all stages of crop growth.

Liquid urea may be utilized both for pre-sowing manure and for foliage feeding. Liquid fertilizer may be applied on the crops' surface both from ground equipment (sprinklers) and from airplanes, or just mixed with irrigation waters. The field tests carried out show a higher efficiency of manure when combining Liquid nitrogen fertilizer with herbicides and microelements.
Agropolychim JSC provides interested farmers with free of charge handbook on how to use and apply Liquid nitrate fertilizer.
Agropolychim JSC offers LIQUID NITROGEN FERTILIZER in containers of different volume or tanks, including transportation to client's site.

SAN - Stabilized Ammonia Nitrate
Download Material Safety Data Sheet
-
General
An Unique product, patented by AGROPOLYCHIM. SAN is an ammonia nitrate fertilizer containing two forms of nitrogen: ammonia and nitric. This is a typical all-purpose product - suitable for fertilization of all crops. It is white or pale yellow in color, easy solving in water, highly hygroscopic. The product's condensing is removed through granulation.
The product exerts the most powerful and immediate effect on the crop yields. In identical conditions the rainfall boosts the efficiency of nitric fertilizers. Efficiency increases as well when a correct combination of nitric and phosphate and potassium fertilization is used.
Storage, packaging and transport:
The product is stored in bulk or in packages in dry, closed warehouse premises, preventing damping or direct sun exposure. It is packaged in valve cassette polyethylene, polypropylene or isolated polypropylene tissue bag – net weight 50 kg or 1mt “bigbags”.
Ammonia nitrate is transported packed or in bilk in any kind of vehicles preventing product damping and in accordance with the rules for transport of specific loads.

Why is NITROGEN necessary?
Nitrogen is a unique feeding element helping the normal growth, development and yield of all crops. It has a special role in the photosynthesis, the foliage shaping, the forming of fruits and seeds and last but not least in the quantity and quality of crop yield. Plants need nitrogen feed for the whole process of growth and vegetation.
Crops differ in their needs of nitrogen for their maturity. Both these specific needs and the conditions of cultivation serve as a basis to the assign nitric fertilization.
Nitrogen deficiency may cause the following:
- Slow growth
- At first pale green, yellow-green and even yellow foliage followed with browning and dying of the leaves
- Low resistance to abiotic and biotic stress
- Early maturing
- Very low yield
- Market appearance and low quality of the crops
Superfluous nitrogen may cause:
- Acceleration of growth with wild increase of foliage and leaves turning to dark green
- Extended period of sterility and vegetation
- Superfluous accumulation of nitrates and proteins
- Increase of crop vulnerability to pollution, dry land and diseases
- Worse crops' technology and taste qualities
Ammonia nitrate provides major ingredient of nitric feed, thus helping farmers for elevated and high quality crop yield. The nitrate and ammonia ions it contains are indispensable feed for the plants. Nitrate ions stay in the soil feed solution and are absorbed immediately by crops.

Fertilization norms
Below are typical amounts for fertilization with Stabilized Ammonia Nitrate according the crop grown and the soil preservation. These norms will vary from specific case to case based on number of factors, such as soil composition, previous fertilization etc, therefore it is crucial to obtain advise from qualified agronomist after conducting the relevant agronomic analysis:

Why is phosphorous necessary?
Phosphorous is one of the three irreplaceable food microelements necessary for the growth, development, productivity and quality of all crops.
Phosphorous is essential because it:
- Speeds up root system growth for young plants
- Shortens the period of fruitless growth of young vineyards and fruits, speeding both the flowering and maturing of fruits.
- Increases crop resistance to freezing and drought
- Plays decisive role in the quality formation of the grain, vegetable, fruit, technical and ether-fatty crop yields.
- Removes the negative consequences of one sided nitrogen fertilization.
Lack of sufficient phosphorous may lead to crops with:
- Weak and abnormal root system development.
- Small and curled at extremes blue-green or dark-green leaves with bronze or violet touch.
- Depressed development, growth, flowering and maturing of fruits.
- Low resistance to freeze and drought.
- Very low in quantity and quality yield.
In the case of more important insufficiency of phosphoric nutrient the above mentioned effects may not be absorbed, but the crops growth and mostly their vegetation shall slow significantly, worsening both yield and quality.
