soil sulfur or sulfuric acid. Soil amendments, besides being expensive, all have downsides. Often they can be short lived. This is because the waters we use for irrigation seldom have adequate amounts of soluble calcium. After a short time the calcium that was applied leaches out of the surface soil where it is needed most.
Recently, the role that soil organic matter plays in helping calcium improve soil structure has been studied more thoroughly. As a result, soil scientists have discovered how important the role of the active ingredient in J&B's Soil Optimizer (the soluble part of soil humus) is, in promoting better soil structure.

Soil Optimizer has a tremendous number of negative charges that form a bridge between calcium, and two separated soil particles . The result of such bonding is the “calcium-clay-humate complex.” The figure above shows the chemical bonds involved. Stable soil aggregates result, causing more permanent improvements in soil structure.
John & Bob's has been shown in the lab by several university researchers to improve soil structure. I have also demonstrated in field trials the practical value of Soil Optimizer in improving soil structure.
I recommend that my customers apply 3 lbs. per 1,000 square feet at anytime of the year. If you take the time to actually look, there will be noticeable improvements in soil structure, as well as plant growth, the first year. If Soil Optimizer is applied three years in a row, you can see further improvements in soil structure and water management.
If you have a water penetration problem due to the use of pure (snow melt) water, inject soluble calcium through the irrigation system. The active ingredient in Soil Optimizer will help make the effects of the soluble calcium more dramatic and longer lasting. Soil Optimizer will add nutrient holding capacity to the soil, improve nutrient uptake for nitrogen, phosphorus and all the micro-nutrients including zinc and iron.
John & Bob have secured a source of humate that is much higher in short chain humic acids and fulvic acids than any other supplier. John & Bob's Soil Optimizer is air dried, while most other sources of humate and leonardite are furnace dried in the cold and wet areas of North Dakota. Furnace temperatures can reach up to 360 degrees thereby deactivating much of the plant active functional groups. The result is a finished product with as much benefit as charcoal briquettes. John & Bob's source material provider has the ability to mine a great number of truckloads at a time ensures consistency of the product. Other companies order one load at a time, and hope the coal manufacturing company sends them the "good stuff". |
