Abstract

The present invention is incorporated in a three-part primary nutrient system for facilitating the growth of a plant in any growing media. The first part of the nutrient system comprises calcium and nitrogen and is devoid of phosphorus, potassium, magnesium, sulfur, and trace minerals. The second part of the nutrient system comprises nitrogen, phosphorus, potassium, magnesium, sulfur, and trace minerals and is devoid of calcium. The third part of the nutrient system comprises potassium, phosphorus, magnesium, sulfur, and trace minerals and is devoid of nitrogen and calcium.

First claim

What is claimed is:

1. A three-part primary nutrient system for facilitating the growth of a plant in any growing media comprising:
a first part comprising calcium and nitrogen and devoid of phosphorus, potassium, magnesium and sulfur;
a second part comprising nitrogen, phosphorus, potassium, magnesium and sulfur, and devoid of calcium; and
a third part comprising potassium, phosphorus, sulfur and magnesium, and devoid of nitrogen and calcium.

2. The three-part nutrient system of claim 1 , the first part further devoid of trace minerals.

3. The three-part nutrient system of claim 1 , the second part further comprising trace minerals.

4. The three-part nutrient system of claim 1 , the third part further comprising trace minerals.

5. The three-part nutrient system of claim 1 , wherein any one of group consisting of the first part, the second part and the third part is in liquid form.

6. The three-part nutrient system of claim 1 , wherein any one of the group consisting of the first part, the second part and the third part is in powdered form.

7. The three-part nutrient system of claim 1 ,
the first part further comprising nitrogen in the range of 3.0%-6.3% and calcium in the range of 2.6%-6.3%, wherein the ranges provided are by volume;
the second part further comprising nitrogen in the range of 1.5%-2.9%, phosphate in the range of 1.2%-3.1%, potash in the range of 2.8%-4.8%, magnesium in the range of 1%-2.1%, sulfur in the range of 1.5%-2.9%, iron in the range of 0.05%-0.35%, and comprising trace minerals in the range of 0.075%-0.125%, wherein the ranges provided are by volume; and
the third part further comprising phosphate in the range of 4.5%-7.5%, potash in the range of 4.5%-7.5%, magnesium in the range of 1.0-2.9%, sulfur in the range of 1.5%-2.9%, iron in the range of 0.08%-0.35%, and comprising trace minerals in the range of 0.075%-0.125% and devoid of nitrogen and calcium, wherein the ranges provided are by volume.
