Nitrogen is a very important nutrient for plants. The element contains 7 protons, 7 electrons and 7 neutrons and is located in the 15th column or family of the periodic table. It is considered a macronutrient because it is present in such large quantities.
Why do plants need Nitrogen?
- Nitrogen is a part of all living cells and is a necessary part of all proteins, enzymes and metabolic processes involved in the synthesis and transfer of energy.
- Nitrogen is a part of chlorophyll, the green pigment of the plant that is responsible for photosynthesis.
- Helps plants with rapid growth, increasing seed and fruit production and improving the quality of leaf and forage crops
Where does it occur naturally? How do plants get it?
Nitrogen comes from the air. It can be put into the soil by lightening or by legumes (bean plants). Legumes have special bacteria inside their roots that change nitrogen from a gas to a form that can go into the soil.
Nitrogen can also be applied in the form of fertilizer.
My plants deficient! What do I do?
Signs of nitrogen deficiency: Upper leaves light green, lower leaves are yellow. Plants growth may slow or stop.
What do I do?
For those who have fields with deficiencies, you can add more nitrogen. Broadcasting urea (highboy or airplane), dropping N solution between the rows, or injecting N in irrigation water are the best application methods at this stage.
