Diammonium phosphate, commonly referred to as (DAP 18-46), is the world's most used phosphate fertilizer. As a primary nutrient, DAP helps the plant to capture and convert the sun's energy into useful compounds for the plant. It also stimulates root development and enhances the durability of the stems.
Usage: In addition to its wide usage in the agricultural sector, DAP is also used to impregnate matches, and as a flame-retardant (for fighting forest fires).
DAP is the most concentrated phosphate-based fertilizer. It is perfect for any agricultural crop to provide phosphorus nutrition throughout crop growth and development, as well as starter dose of nitrogen and lower sulphur.
It can be applied in autumn for tilling and in spring during sowing, as well as pre sowing cultivation. Dissolving in soil, it provides temporary alkalization of pH of the soil solution around the fertilizer granule, thus stimulating better uptake of phosphorus from the fertilizers on acid soils. Fertilizer's sulphur also contributes to the better intake of nitrogen and phosphorus by plants.

USAGE
More than 90% of world industrial production of Urea is destined for use as nitrogen release fertilizer. Urea has the highest nitrogen content of all solid nitrogen content of all solid nitrogenous fertilizers in common use. Therefore, it has the lowest transportation costs per units of nitrogen nutrient. The standard crop nutrient rating of urea is 46 0-0.
The most common impurity of synthetic urea is Biuret, which impairs plant growth.
Urea is usually spread at rates of between 40 and 300 Kg./HA but rates vary. Smaller applications incur lower losses due to leaching. During summer season, Urea is often spread just before or during rain to minimize losses from volatilization (A process wherein nitrogen is lost to the atmosphere as Ammonia Gas). Because of the high Nitrogen concentration in Urea, it is very important to achieve an even spread. The application equipment must be correctly calibrated and properly used.
Urea ammonium nitrate solution, commonly referred to as UAN, is a liquid nitrogen fertilizer which is made up of a mixture of urea, ammonium nitrate and water.
Nitrogen fertilizer is responsible for the production of amino acids and proteins and indirectly supports the production of vitamin B. Nitrogen application is the main factor to improve plant growth, development and yield of all crops.
Usage: The use of modern crop application methods of UAN are designed to provide very precise application of UAN to the crop. Furthermore, UAN applications can provide better economics for the farmer than dry fertilizer applications because the farmer can add other crop protection products like herbicides, insecticides and fungicides to the UAN and can be applied to the crop in a single application.
