FERTILIZERS

Detecting the carbon and nitrogen content in liquid fertilizer is essential to maintain the expected yields and ensure a healthy crop. The CN 802 Carbon/Nitrogen Analyzer is designed to deliver precise and accurate measurements of carbon and nitrogen content in environmental and agricultural samples.

Characterizing the nitrogen forms in liquid fertilizers is essential for understanding their nutrient content, availability, and potential effects on crops and the environment. Indeed, different forms of nitrogen are taken up by the plants in different ways, thus characterizing the type of nitrogen contained in fertilizers is crucial to develop the most efficient fertilizing program.

The digestion phase is the most time-consuming step of the Kjeldahl analysis. Speeding up the process and ensuring a proper outcome is of fundamental importance when it comes to efficiency in the laboratory.
VELP designed seven different types of accurately pre-dosed KjTabs™ tablets to speed up the mineralization process. Along with catalysts, VELP produces antifoaming KjTabs™ to reduce foam formation during the initial phase of the mineralization process.

Healthy plants often contain 3 to 4 percent nitrogen in their above-ground tissues. This is a much higher concentration compared to other nutrients. Nitrogen is so vital because it is a major component of chlorophyll, the compound by which plants use sunlight energy to produce sugars from water and carbon dioxide (i.e., photosynthesis).

A fertilizer is any type of organic or inorganic substance that contains nutrients, macroelements or microelements, in forms assailable by plants, to maintain or increase the content of these elements in the soil, improve the quality of the substrate at the nutritional level, stimulate the vegetative growth of the plants, etc.

Sulphur is one of the 17 essential plant nutrients. It is essential for the growth and development of all crops, without exception. Like any essential nutrient, sulphur also has some key functions in plants

Solid Fertilizers are substances containing the main chemical elements needed to improve the growth and productiveness of crops. It is therefore essential to determine the Nitrogen content of solid fertilizers. The Dumas method is one of the most common analyses to determine Nitrogen in fertilizers, following AOAC 993.13.

Urea is a crystalline substance widely used as a fertilizer, feed supplement, and starting material for plastics and drugs. It has a very high nitrogen content; it is readily converted to nitrate in the soil and is therefore considered one of the most concentrated nitrogenous fertilizers. The importance of having a controlled Nitrogen content in this product is crucial to always keep the same production standards.
