Plant and algae extracts can be used as nutritional supplements in agriculture and horticulture to increase plant growth and yield. Optimum leaf applications help the plant to get improved leaf gas exchange properties, and proline (free amino acid)

Accumulation in plants treated with Optimum leaf shows increased growth and a higher total plant dry weight, stem diameters, and absolute growth rate. Plants without Optimum leaf have lower leaf gas exchange (photosynthesis, stomatal conductance, and plant transpiration) and leaf chlorophyll content.

Physiological processes such as photosynthesis, stomatal conductance, transpiration, growth rates, and biochemical processes such as proline production, are positively influenced by the use of Optimum leaf.

Optimum leaf carries a mix of acids, plant extracts and vegetable oil.

Optimum leaf is an extract which has to be diluted to a pre advised concentration, due to the nature of the product it has to be applied in concentration of the total amount applied to the plants.
