PLANT NUTRIENTS ESSENTIAL FOR GOOD PRODUCTION

18 Elements are considered essential for plant growth. Carbon, Oxygen and Hydrogen are supplied to the plant by air and water. The balance must be obtained from the soil. A deficiency of only one plant nutrient can either prevent or reduce growth to unsatisfactory levels, or make plants vulnerable to diseases. Therefore fertilizers are applied to replenish nutrients in the soil. Nutrients are divided into 3 categories: 

1. MAJOR NUTRIENTS

NITROGEN (N)

Important in protein synthesis and integral part of all amino acids (building blocks of protein)
Promotes vigorous growth of stems and leaves
Component of chlorophyll, manufacturer of the plants food
Evidenced by green colour

PHOSPHORUS (P)
Promotes strong root development (Essential for root growth)
Promotes sturdy structural growth of plant
Improves size and yield of fruit, flower and seed production
Essential in energy transformation within cells, therefore vigor
Necessary for starch deposits in storage organs

POTASSIUM (K)
Overall hardiness and good health of plant
Flavour of fruits, nuts and vegetables are enhanced by correct development of sugar and starches
Improves plants tolerance to heat, cold, drought and stress conditions
Regulates the use of water in plants
Essential for fruit and flower production
Responsible for strong cell formation, protein production and root development
Important in production of plants food (photosynthesis)
Helps to harden plant tissue (better resistance to insect attack and better plant structure)
Catalyst for many biochemical reactions, especially photosynthesis
Important in synthesis of amino acids
 

2. MINOR NUTRIENTS

CALCIUM (Ca)
Promotes plant vigor and strong plant tissue (resistance to insect attack)
Promotes early root formation and seedling growth
Aids in the uptake of all other nutrients
Balances soil chemistry (pH of soil)

MAGNESIUM (Mg)
Essential element in the formation of Chlorophyll
Formation of sugars
Carrier of Phosphate and starches through the plant
Promotes the formation of oils and fats.
Vital for healthy growth

SULPHUR (S)
Increased root development
Helps to maintain the dark green colour
Stimulates seed production
Necessary for protein production (component of some amino acids)
Flavour and odour component in many fruit and vegetables
 

3. MICRO NUTRIENTS

BORON (B)

Promotes early root formation and growth
Improves plant vigor and sturdiness
Increases yield and improves quality of fruit and vegetables

CHLORINE (Cl)
Involved in photosynthesis and chlorophyll production
Stimulates enzyme activity
Helps control water loss and moisture stress

COBALT (Co)
Needed in nodules of legumes for nitrogen-fixing bacteria (rhizobium, soyabean and alfalfa)
Stimulates growth, transpiration and photosynthesis

COPPER (Cu)
Needed for chlorophyll production
Catalyst for several plant reactions
Necessary for oxidation and production of protein

IRON (Fe)
Oxygen carrier
Enhances chlorophyll formation
Metabolizing RNA
Enhances green colour of produce

MANGANESE (Mn)
Activates many metabolic reactions
Increases absorption of calcium, magnesium and phosphorus
Speeds up seed germination and plant maturity

MOLYBDENUM (Mo)
Enhances absorption of nitrogen by plants

SODIUM (Na)
Water regulation function
Photosynthesis

ZINC (Zn)
Essential for enzymatic reactions in cells (Amino-acid and Chlorophyll production)
Promotes plant growth
