Soil Nutrients

There are 17 essential elements involved in plant nutrition

  

The Role of Essential Elements

PRIMARY (MACRO) NUTRIENTS

Nitrogen (N), Phosphorus (P), and Potassium (K) are the most frequently required in a crop fertilization program.

  • Nitrogen is necessary for the formation of amino acids, proteins, DNA and RNA. It is essential for plant cell division and vital for plant growth.

  • Phosphorus promotes early root formation and growth, and is involved in photosynthesis, respiration, energy storage and transfer, cell division and enlargement. 

  • Potassium is involved in carbohydrate metabolism and the break down and translocation of starch. Potassium also enhances disease resistance and improves winter hardiness.

 

SECONDARY NUTRIENTS

Calcium (Ca), Magnesium (Mg), and Sulfur (S) are required in lesser amounts than macronutrients, but each is equally important to the crop. 

  • Calcium increases fruit set and quality and is important for continuous cell division and formation (regulates hormonal activity).

  • Magnesium, the center molecule of chlorophyll, improves utilization and mobility of phosphorus.

  • Sulfur is an integral part of amino acids. It helps develop enzymes, vitamins and oil contents, and aids in seed formation.

 

MICRONUTRIENTS

Boron (B), Zinc (Zn), Copper (Cu), Manganese (Mn), Iron (Fe), Chloride(CI) and Molybdenum (Mo) are used in minute amounts but are just as important to plant growth and development as the major nutrients. Some micronutrients control the uptake of major nutrients and key processes.

  • Boron is an essential component of cell wall formation and is key for the germination of pollen grains and growth of pollen tubes.

  • Zinc aids plant growth hormones and enzyme system and is necessary for chlorophyll production and carbohydrate formation.

  • Copper plays a major role in photosynthesis. This element improves the flavour of fruits and vegetables and can help prevent ergot in cereals.

  • Manganese aids in chlorophyll synthesis and increases the availability of phosphorus and calcium.

  • Iron promotes the formation of chlorophyll and acts as an oxygen carrier.

  • Chloride promotes crop health and enhances the maturity of small grains on some soils.

  • Molybdenum is needed to convert inorganic phosphates to organic forms in the plant and aids in the nodulation of legumes, especially in acidic soils.

 

These are just a few of the ways that essential elements contribute to crop health.
