Plant Nutrition & Growth Enhancements
Intro to Nutrients: Which Elements Do Plants Need?
Introduction
A plant obtains everything it needs to grow from one of two places: the air around its leaves, or the water around its roots. The air supplies carbon and oxygen. Water supplies hydrogen and also acts as a carrier for a variety of other elements. These elements are known as "plant nutrients" and are essential for a plant to grow and bloom.
Essential Elements
Secondary Nutrients
Calcium
Strengthens cell walls (think of strong bones) and helps to retain other elements.
Magnesium
Contributes to crop quality, leaf chlorophyll, and enzymes.
Sulfur
Forms an essential component of many amino acids and proteins. Also aids root growth.
Micro Nutrients
Boron
Needed for root, shoot, and fruit development.
Chlorine
Aids plant metabolism.
Copper
Influences photosynthesis, aids root metabolism, and reproductive growth (e.g. seeds).
Iron
Influences photosynthesis and an essential part of chlorophyll production.
Manganese
Help enzymes to break down carbohydrates and assists in nitrogen metabolism.
Molybdenum
Plays a key role in plant enzyme systems that control the uptake of nitrogen.
Zinc
Part of the production of important plant hormones like auxin (which regulates growth).
