How to quickly determine the nutrients in diammonium phosphate?
Thread Content
There are currently two products: 57% DAP and 64% DAP. Due to insufficient labeling, it’s difficult to tell which one contains 57% and which one contains 64% of the nutrient. Is there any quick way to determine which one is which?
The fastest way is to guess – there’s at least a 50% chance of getting it right. To determine the content of chemical substances, quantitative analysis is required. This requires finding a laboratory, but the testing takes some time.
I’m not sure if it’s possible to measure density; will it work?
Okay, it can be tried, but a batch of basic data needs to be prepared first
I’m just guessing too, because substances with different concentrations may have different densities
Well, I thought about it before as well, but I didn’t put it into practice; it’s still determined by testing the nitrogen content
The pH value should be able to give an indication; a pH of 64 is likely to be on the higher side
