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.

Claims (26)

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 trace minerals;

a second part comprising nitrogen and devoid of calcium; and

a third part comprising at least one of potassium, phosphorus, sulfur, magnesium, or minor minerals and devoid of nitrogen and calcium.

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

3. 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.

4. 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.

5. 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%, wherein the ranges provided are by volume; and

the third part further comprising at least one of 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%, or minor minerals in the range of 0.075%-0.125%, wherein the ranges provided are by volume.

6. The three-part nutrient system of claim 1 , the first part devoid of phosphorus, potassium, magnesium and sulfur.

7. The three-part nutrient system of claim 1 , the second part further comprising phosphorus, potassium, magnesium and sulfur.

8. The three-part nutrient system of claim 1 , the third part comprising at least four of potassium, phosphorus, sulfur, magnesium, or minor minerals.

9. 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 minor minerals in the range of 0.075%-0.125%, wherein the ranges provided are by volume.

10. A three-part primary nutrient system for facilitating the growth of a plant in any growing media comprising:

a first part 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;

a second part comprising nitrogen in the range of 1.5%-2.9%, wherein the range provided is by volume, and devoid of calcium; and

a third part comprising at least one of potassium, phosphorus, sulfur, magnesium, or minor minerals and devoid of nitrogen and calcium, the third part further comprising at least one of 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%, or minor minerals in the range of 0.075%-0.125%, wherein the ranges provided are by volume.

11. A three-part primary nutrient system for facilitating the growth of a plant in any growing media comprising:

a first part 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;

a second part 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 devoid of calcium; and

a third part comprising at least one of potassium, phosphorus, sulfur, magnesium, or minor minerals and devoid of nitrogen and calcium, 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 minor minerals in the range of 0.075%-0.125%, wherein the ranges provided are by volume.
