BBoron
Boron is essential for all plant growth, aiding in the transfer of sugars and nutrients from leaves to fruits, and for specific functions in yield production by increasing pollination and seed development.
Boron is an essential nutrient for root growth, cell division and is key for optimum pod production.
Application
- It is used in soil and foliar sprays and in fertigation programs.
- Solubor is highly water soluble, and is commonly applied in foliar sprays.
- Compatible with most pesticides.
- Because the season for the most effective foliar application of boron is short, foliar
sprays must be prepared quickly and accurately.
- Application rate is 2.4 lbs of Solubor/acre, which provides 0.5 actual B per acre.
