 Boron functions in plant:
- Transporter of sugars through cell membranes
- Required for cell division and development
- Involved with plant’s utilization of nitrogen and phosphate
- Involved in the synthesis of protein and nucleic acids
- Required for germination of pollen grains, flowering and reproduction, and seed formation
Boron can be deficient in:
- Sandy, low organic matter, well leached soils
- High soil pH
- Dry and drought conditions
- High levels of nitrogen and calcium, natural or applied
- Cold, wet weather
Symptoms:
- Poor fertilization and poor seed and/or fruit set
- Stunting and/or death of terminal bud (rosetting)
- Leaves/stems can thicken, leaves curl, and may become brittle
- Yellowing of new growth, reduced flowering
- Barren heads/stalks or poorly filled ears
Critical levels in plant and soil tests:
- Plant Tissue: parts per million (ppm)
Critical levels at about 10-100 ppm
- Corn: 5-25 ppm
- Alfalfa: 30-80 ppm
- Wheat: 5-25 ppm
Soil Test: parts per million (ppm), 0-6”, Mehlich III extraction
- Deficient: <0.5 ppm
- Marginal: 0.5-1.0 ppm
- Sufficient: >1.0 ppm
Use Boron 10 for fall and pre-plant boron deficiency prevention. Boron 10 is the product of choice for broadcast and band boron applications in a wide range of conditions.
Highly water-soluble boron at 80%. Boron 10 exceeds industry water-solubility standards.
Crop essential sulfur at 3%. All the sulfur in Boron 10 is in the immediately available sulfate form.
Boron 10 delivers 33% more granules per acre as compared to a 15% boron product. Basis 1# of actual boron per acre, Boron 10 delivers nearly 230,000 granules per acre versus less than 160,000 from a 15% boron source. More granules per acre results in more feeding sites, which provides for better nutrient uptake. |
