SOIL AND PLANTS

Find out how to determine Carbon, Hydrogen, Nitrogen, and Sulfur in soil samples.

It is always more important to know the ingredients and amount of all the components, for different reasons, including legal and nutritional purposes (labeling).
Learn how to obtain excellent performance with FIWE Series and how to work in accordance with ISO.

Learn about RESPIROMETRIC Sensor System for Soil Analysis; VELP's laboratory equipment designed to measure the soil respiration in order to:
- determine the soil microbial activity;
- establish the effect of additives (nutrients, pollutants, soil improvers, etc.) on the metabolic performance of microorganisms;
- determine the microbial biomass.

Learn how to obtain the optimal rate of plastic material biodegradation in test soil by controlling soil moisture, as well as, determining the ultimate biodegradability of the material itself. A non-specific soil is used as the inoculum because the test simulates the processes of biodegradation that occurs in a natural environment.

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.

Learn how to determine nitrogen in solis. The nitrogen in plants is a part of numerous compounds, including proteins, enzymes, nucleic acids, chlorophyll and vitamins essential for all biological functions.

Nitrogen is the most important nutritional element for plants, since it is involved in building of their proteins, nucleic acids and other several cell components. Learn how to obtain excellent performance with NDA Seriesand how to work in accordance with AOAC, AACC and ICC.

Nitrogen fertilization is one of the most important factors of agricultural production. The quantity of nitrogen in the soil must be kept under control to prevent an excessive use.
Learn how to obtain excellent performance with NDA Series and how to work in accordance with AOAC and ISO.

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.
