Q. What are the disadvantages of urea?

Urea has several advantages, including cost per pound of nitrogen, higher nutrient density and good handling and storage properties. The biggest disadvantage is the potential for volatilization. This occurs when urea is surface-applied and converted to ammonium carbonate by urease.

Q. How long does urea stay in the soil?

14 days

Q. Which is better NPK or DAP?

The farmers objected arguing that they wanted to use the fertiliser they trusted — DAP.

Q. Is DAP safe to use?

A: Diammonium phosphate, also known as DAP, often gets a bad rap. It’s a chemical that some winemakers add to their wines during fermentation, and its non-enological uses include plant fertilization and fire retardation. But it really isn’t as scary as it sounds; in fact, it isn’t scary at all.

Q. Can vs DAP?

Nitrate in CAN is taken up by the plant faster than ammonium in Urea and DAP and you lose less Nitrogen to the air. … What is the difference between Urea, DAP and CAN? The nitrogen used in urea and DAP is in the form of ammo- nium while the nitrogen in CAN is in the form of nitrate.

Q. Which DAP fertilizer is the best?

Hindalco produces di-ammonium phosphate (DAP) fertiliser. It is the most popular phosphatic fertiliser because of its high nutrient content and good physical properties. The composition of DAP is 18% Nitrogen and P2O5 46%.

Q. What does DAP fertilizer do?

Diammonium phosphate (DAP) NP 18:46 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.
