An actual comparison of two types of fertilizer, AGGRAND Natural Fertilizer 4-3-3 and one that is chemical, illustrates the difference. One homeowner applies 30-5-10 fertilizer to his or her lawn at 20 pounds per 5,000 square feet and a neighbor applies one quart of AGGRAND Natural Fertilizer 4-3-3 (2.3 pounds) of fish-kelp humate fertilizer per 5,000 square feet. The natural fertilizer puts .0184 pound and .013 pound of phosphate per 1,000 square feet into the soil. The naturally fertilized lawn is more drought and pest resistant and uses less water so it needs less frequent irrigation. The AGGRAND fertilizer stimulates biological activity, which creates stable soil aggregates enabling the roots to go deeper and become better developed, keeping nutrients in the root zone.

The chemical fertilizer puts 1.2 pounds of nitrogen and .2 pounds of phosphate per 1,000 square feet into the soil (65 times more nitrogen and 15 times more phosphate than the natural fertilizer). The chemically fertilized lawn and/or pasture is water hungry and needs constant irrigation because the grass relies on the chemical to supply the nutrients. The chemical toxifies the soil, inhibiting biological activity, which results in compacted soil and an unhealthy root environment. Most of the nutrients are free to flow over the compacted surface into the surface water or past the restricted root zone into the ground water. Research show that up to 96 percent of high analysis chemical fertilizers are not taken up by plants.
