How to calculate fertilizer nitrogen
Nitrogen is one of the key nutrients in the consumption of chemical fertilizers, which plays a vital role in the development of vegetation. Many agricultural and fertilizer producers want to be able to accurately calculate the amount of nitrogen in fertilizers to ensure optimal crop development. Therefore, understanding how to count nitrogen in fertilizers is able to not only enhance crop yields, however also help prevent over-fertilization and environmental contamination. This article will explain in detail how to calculate nitrogen in fertilizers, and examine common methods and precautions. In my experience, Nitrogen chemical forms
In fertilizers, nitrogen usually exists in different chemical forms, the most common ones include amino nitrogen (NHLgreater) and nitrate nitrogen (NOLgreater). In different fertilizer items, the chemical form of nitrogen might be different, affecting its consumption effect. For example to instance, the nitrogen in urea is present as ammonium nitrogen (NH₂), while the nitrogen in ammonium nitrate is present as nitrate nitrogen. From what I've seen, Therefore, understanding the chemical form of nitrogen is the first measure in calculating the amount of nitrogen in fertilizers. Nitrogen content calculation method
How to Calculate Nitrogen in Fertilizers Two main methods of calculation are usually applied: by chemical analysis and by the nominal nitrogen content of the fertilizer. Additionally The following is a specific analysis of these two methods:
By chemical analysis:
The nitrogen content of chemical fertilizers is able to be accurately determined by chemical analysis. But frequently applied methods include Kjeldahl nitrogen determination and spectral analysis. The Kjeldahl method converts the sample into ammonia by reacting it with concentrated sulfuric acid, and then determines the nitrogen content by titration. This method is accurate, however needs professional experimental equipment and methodology. In my experience, In particular By the nominal nitrogen content method:
Each fertilizer is usually labeled with its nitrogen content on the package. According to research to instance, urea has a nitrogen content of about 46% and ammonium nitrate has a nitrogen content of about 34%. By consulting the product label, you is able to roughly understand the content of nitrogen in fertilizers. This method is fast and simple, and is suitable to most agricultural producers. Calculation example: Urea and ammonium nitrate
To help you better understand how to calculate nitrogen in fertilizers, here are two examples of common fertilizers:
Urea: Urea has the formula CO(NH₂) with a nitrogen mass of 28g/mol. If the mass of urea is 100 grams, then the nitrogen content in it's:
100g x 46% = 46g nitrogen. This leads to an actual nitrogen content of 46 grams in urea. Ammonium nitrate: The molecular formula of ammonium nitrate is NH4 NO, where the mass of nitrogen is 28g/mol. The nitrogen content of ammonium nitrate is about 34%. If the mass of ammonium nitrate is 100 grams, then the nitrogen content in it's:
100 grams x 34% = 34 grams of nitrogen. I've found that In this way, the nitrogen content in the ammonium nitrate is able to be calculated. Nitrogen fertilizer consumption considerations
When applying nitrogenous fertilizers, the mode of nitrogen emit and the needs of vegetation must be taken into account. And overuse consumption of nitrogen fertilizer is able to lead to rapid development of crops, and might lead to eutrophication, soil systems acidification and other environmental problems. The stability between the emit rate of nitrogen and the ability of vegetation to absorb it's crucial, and moderate fertilization is able to increase crop yields while reducing environmental contamination. rational fertilization
Different crops have different standards to nitrogen, so it's very crucial to calculate the nitrogen in chemical fertilizers and apply them reasonably according to the demand of crops. Understanding the nitrogen content of soil systems, the development stage of crops and the timing of fertilization will help to enhance the efficiency of fertilization. And Summary
In agricultural production, the correct calculation of nitrogen content in fertilizers is the basis to ensuring the healthy development of crops. Whether through chemical analysis or through the nominal nitrogen content method, understanding the specific content of nitrogen is able to help farmers optimize fertilizer consumption, so as to achieve the goal of growing yield and reducing environmental contamination. I hope that through this article, we is able to greater clearly understand how to calculate the nitrogen in fertilizer, and apply it to the actual agricultural production, enhance the sustainability of agriculture.
