42N, a urea ammonium nitrate solution (UAN 42:0:0) is a widely used N fertilizer in cereals. It is highly stable, mobile and concentrated liquid fertilizer containing readily available ammonium, nitrate, and urea
nitrogen. The amount of N applied is a major determinant in grain yield in cereals. Generally applied at 10-30Kg N/ha at seeding, then top dressed N as foliar and/or broadcast applications at key stages of growth. The rate of application also depends upon the N mineralization in the paddock. Nitrogen is the key element required for the growth and development of plants. It helps in overall growth of the crop, protein biosynthesis, chlorophyll synthesis, and encourages tillering and leaf area development.
42N contains one quarter each of ammonium and nitrate nitrogen and one half is urea nitrogen to cater to the immediate and long term N nutrition of various crops.
The ammonium nitrate component in 42N is rapidly available as soon as it reaches the root zone.
The nitrate nitrogen fraction is fully available for immediate uptake and metabolism. This fraction is prone to leaching after heavy irrigation and/or rainfall.
The urea portion moves freely with the soil water until it is hydrolysed by soil bacteria to ammonium nitrogen.
42N is a clear liquid fertilizer, easy to handle and store.
This product can either be foliar applied or at seeding to supply nitrogen at critical stages of growth, especially during the winter months to improve growth, protein and grain yield.
product is buffered to provide optimum nitrogen availability in most soil types.
Surface dribble-band applications of 42N tend to be somewhat more efficient than broadcast urea, particularly when conditions encourage volatilization losses. Urea is most commonly used fertilizer as nitrogen source; however, its conversion to the ammonium and nitrate forms is restricted under low soil temperature conditions. Crops fertilized with urea alone under winter conditions fail to show any immediate N response due to poor nitrification process.
Foliar applications of 42N at later stages of growth improve protein content in grain. Many ag-chemicals can be applied with 42N, however check with physical compatibility prior to mixing. 42N can be conveniently tank mixed with trace elements, calcium, sulphur, phosphorus and potassium fertilizers at the recommended rates when diluted with water.
