Advantage of Foliar Fertilization over Soil Fertilization Soil Application Foliar Application
Faster uptake (within hours)
No tie up by soil
More efficient (3-100 times)
Activate plant metabolism stimulating photosynthesis, uptake of water and nutrients
Foliar applications are faster acting and more efficient!
Importance of Balanced Nutrition The limiting factor for holding capacity of a barrel is the shortest stave. The limiting factor for growth is the nutrient in shortest supply. A short supply of nutrients reduces yields, causing reduced profits. Iron Zinc Potassium Nitrogen Copper Boron Calcium Iron Zinc Potassium Nitrogen Copper Boron Calcium
Nutrient Deficiencies By the time deficiencies are visible, yields have been reduced! Prevent deficiencies with a regular maintenance program, or with frequent foliar analyses followed by application of the appropriate nutrient(s). Visible deficiencies Hidden deficiencies Yields Genetic Potential Nutrient deficiency
Examples of Visible Deficiencies Iron Potassium Zinc By the time deficiencies are visible, yields have been reduced!

Effects of NutriPlus on pH of Water NutriPlus decreases the pH which increases rate of absorption and translocation .
Increases crop yield and quality through these modes of action:
Increased chlorophyll content and photosynthesis
Increased nutrient uptake through root
Antioxidant activity to reduce abiotic stress
Elicitor activity to reduce biotic stress
How Do NUTRI Products Work?
Mode of Action I N UTRIPLANT AG Enhances Two Critical Processes in Crop Physiology 1. Photosynthesis 2. Nutrient uptake through roots
N UTRIPLANT AG Increases Chlorophyll Development Photosynthesis is how the plant traps energy from the sun.

Mode of Action II Increased Absorption of Nutrients by Roots
Plants with foliar applications of N UTRIPLANT AG absorbed 56% more Mn, 200% more Fe and Zn, and 370% more Cu N UTRIPLANT AG Increases Absorption of Nutrients by Roots
Even with optimal photosynthesis and nutrient uptake, crops do not reach their full genetic potential due to STRESS.

American Society of Plant Physiologists, Rockville, MD, pp 1158–1249. Mode of Action III Abiotic Stress (Extreme temperatures, UV radiation, drought, salinity, etc.)
Abiotic Stress Includes Photooxidation (Damage Caused by ‘Free radical Oxygen’)
Occurs in crops when there is excess light
Photosynthesis is reduced, resulting in reduced productivity
Leaves may turn yellow, and drop early
