John and Bob’s Soil Optimizer is formulated around the concept of very small amounts providing powerful and previously unheard of benefits. Calculate how little you need for your garden based on our recommended rates and you will be amazed. It is a concentrated and comprehensive, blended approach to organic soil nutrition. Our blend is a proprietary mix so we can’t divulge all ingredients but we can demonstrate the synergistic concept by examining the relationship between the ingredients listed on the label (soluble concentrated humus and iron). Several unlisted ingredients provide additional synergistic benefits. Greenhouse research and field trials have documented that plants respond more positively to iron with soluble concentrated humus than to soluble concentrated humus or iron alone. Researchers have found that soluble concentrated humus is an inexpensive chelating (collecting) agent that makes iron more mobile in the soil and within plants. Soluble concentrated humus offers the best solution because it is of ideal chelating strength and is one of the very few organic chelating agents that remain in the soil for long periods of time. When soil pH is above 6.0, inorganic forms of iron are insoluble and immobile. Only organically complexed forms of iron are soluble and mobile enough to support a plant’s needs. Once iron enters the plant it doesn’t move well. This is why newer leaves exhibit chlorosis symptoms more than older leaves. Yields can be severely reduced because iron plays such a crucial in chlorophyll synthesis. We have been stunned by the ability of John and Bob’s to, in effect, unleash iron and cure ill or underperforming plants. We believe this is, in part, because the soluble concentrated humus in John and Bob’s chelates (collects) iron, thereby improving it’s availability to plants. Soluble concentrated humus is nature’s way to complex iron. Studies conducted on permanent crops using radio isotope labeled iron showed that soluble concentrated humus moved iron through vascular tissues into leaves under conditions where iron alone did not move in the plant. Soluble concentrated humus has an ideal balance of chelate strength, plant mobility, soil durability and cost, and is one of the star performers in our synergistic blend. John and Bob’s improves iron uptake and translocation, resulting in dramatically better chlorophyll density (greener, healthier plants). John and Bob’s treated plants photosynthesize faster and grow faster than non treated plants. As a result, nearly all plant functions are enhanced and plant performance is optimized, resulting in better yields, lusher appearance, less disease and decreased dependence on chemical fertilizer.
