Phi™ delivers 5% Iron and is effective in correcting Iron chlorosis. It stimulates growth and improves plant vigor on crops grown in marginal soils, particularly where salinity or oil-soaking is a problem.
Iron and Manganese have an antagonistic relationship, so the uptake and availability of each is affected by the other. Manganese and iron uptake are affected by soil pH, free lime, and irrigation water high in bicarbonates. Deficiencies are often seen in the spring, when cool, moist soils tie up iron and manganese. Foliar applications of nutrients tied up in the soil are the fastest way to correct an imbalance.
Phi™ Delivers 5% Iron to Crops
- Corrects Iron chlorosis
- Improves photosynthesis and energy production
- Slow-release formulation reduces phytotoxicity
- Stimulates growth and crop vigor
Factors that Contribute to Iron Deficiencies
- Low soil Fe levels
- Free Calcium Carbonate
- High Bicarbonate
- High soil P
- Heavy manuring
- Root damage
- Low soil temperatures
- Genetic factors
- Moisture extremes
- Low organic matter
- Poor aeration (excess CO2)
- Temperature extremes
- High amounts of Mn, Zn, Cu, Ni
- Excess soil acidity
- Soil Fungi or nematodes
