Using the Leaf as the Fertilizer Carrier
The liquid spray contains a small amount of a sticker – usually a latex based ingredient that “sticks” the spray to the leaf. Then with regular mowing a small portion of the leaf is cut off and falls into the canopy of the lawn. This fertilizer coated leaf is then composted into plant food. The lawn is fed according to demand – faster growing lawns yield more fertilizer coated clippings to feed the lawn and vice versa.
Mostly Water, Not a Bunch of Chemicals
The lawn spray liquid is a mixture of mostly water (95%), a small amount of fertilizer (4.5%) and an even a smaller amount of pesticides and additives (0.5%). The liquid is NOT a bunch of chemicals – your lawn doesn’t need a lot of fertilizer or insecticides, but you do need a lot of water to spread it evenly over your lawn.
The liquid works by coating and bonding to the leaves of grass in your lawn - effectively turning the leaf into “slow release organic plant food”. Like vitamin supplements added to food, the coated leaf blade becomes nutrient rich plant food. When cut, the coated leaf falls into the lawn to be composted into plant food.
How Does the Lawn Compost
When the lawn is mowed, the cut enriched leaves fall into the canopy. That nutrient rich leaf is enzymatically digested by soil microbes and recycled into plant food – aka composting. This provides a slow release mechanism that continuously feeds the lawn over a 2 month period.
How Lawn Spraying Protects Your Lawn
The insecticides also coat and bond to the leaf blades. But unlike the fertilizer, the insecticides are most effective before composting. The insecticides used in the spray have an immediate impact on the insect population – knocking down insect populations to near zero. With each mowing the same nutrient rich leaf carries a small amount insecticides into the lawn to further reduce insect populations. Then as the leaf is composted, the insecticides are broken down into plant nutrients too!
Why Liquid is Superior to Granular Formulations
Liquid fertilizers can be custom blended every day whereas granular fertilizers are fixed formulation. Custom blending allows for the lawn spray company to be nimble and adjust for prevailing conditions. This is not possible with fixed granular formulations where the only adjustment is to vary the amount applied. But liquid applications, every ingredient can be finely tuned every day for maximum results.
Liquid Fertilizer Do Not Wash Away
No, rains do not wash away liquid fertilizers! The best analogy is think of iron filings clinging to a magnet. The fertilizer is like the iron filings and the leaf and other organic matter is like the magnet. Once the liquid containing fertilizer comes in contact with the leaf, the fertilizer “clings” to the leaf using magnetic charges. You can prove this by watching your lawn green up after a rain – moist soils compost better and aid in the uptake of nutrients – not the washing away of nutrients.
