Some of the Nutrients and what they do for your trees
| Nitrogen | is needed to form the protein in the plant or the basis of cell multiplication as growth and life itself. An excess of nitrogen will cause potassium deficiency. |
| Phosphorus | like nitrogen is needed for growth. |
| Potassium | serves particularly in carbohydrate production. Taken from the soil by the plant it helps to utilise the air, water and sunshine which produce the body or mass of the plant.Excessive potassium, sodium and magnesium will cause calcium deficiency. |
| Calcium | and Magnesium are part of the cell walls of plants.Cells of root hairs are membranous tissue are constructed of cellular fibres tied together by calcium (and magnesium). The root membranes with their necessary calcium determine whether nutrients move from the soil into the root in proper amount and balance to bring about plant composition.Soft Nose is caused by deficiency of Calcium and Boron.Excessive calcium will cause magnesium and phosphorus deficiency. |
| Magnesium | In the soil excess magnesium will cause potassium, phosphorus, calcium and nitrogen deficiency. |
Other important factors
When proteins are to be produced, that is, if the nitrogen, and in some cases phosphorus and sulphur are to be coupled up with carbon, hydrogen and oxygen to make this life-carrying, body building substance they cannot be built by sunshine using only air and water. The soil must contribute at least ten elements which include Calcium, Phosphorus, Potassium, Magnesium, Sulphur, Iron, Boron, Manganese, Copper and Zinc.
Analysing your Soil
A soil analysis program will provide important and essential information on the soils nutritional status, which enables decisions of fertiliser and micronutrient applications to maximise the quantity and quality of crop yields.
