Chemical – Nitrogen Determination in Fertilizer
Plants absorb oxygen, hydrogen, and carbon dioxide from the air. Plants utilize these elements to produce carbohydrates through the photosynthesis process. In order to make vital proteins and amino acids, plants will require other 13 elements.
The primary nutrients are: nitrogen, phosphorus, and potassium because they are building blocks for amino acids, proteins, cell membranes and ATP. The secondary nutrients: calcium, magnesium, and sulphur. And the micronutrients: zinc, iron, manganese, copper, boron, molybdenum, and chlorine. Each of the elements play an important role in plant growth.
Nitrogen is the element that get the most attention in fertilizer industry. Nitrogen is used to synthesize amino acids, proteins, nucleic acids, chlorophyll and enzymes. Nitrogen molecule (N2), but this form of Nitrogen cannot be used and absorbed by plants and animals. This Nitrogen molecule must first combine with Oxygen or Hydrogen to produce compounds such as Ammonium and nitrate or other organic form of Nitrogen. This transformation occurs naturally in Nitrogen Cycle.
The rate of plant growth is proportional to the rate of nitrogen supply. If the soil is deficient in Nitrogen, the plants become stunted and pale. However, an excess of Nitrogen can damage the plants just as over-fertilizing the lawn can burn and damage the grass.
C. Gerhardt offers a fully automated computer controlled combustion system which is according to the Dumas method for Nitrogen determination.
