Boron Nutrient Info
Boron - Quick Facts
- Boron is essential for the plant growth and cell development.
- Essential for seed and fruit development.
- Improves stability and function of cell wall membranes.
- Promotes synthesis of structural carbohydrates in the cell wall.
- Flowering and nodule formation depend on adequate Boron.
- Boron plays roles in formation of sugar complexes for translocation within plants, and in the formation of proteins.
- Form used by plants: H3BO3, B(OH) -4 (at high pH)
Boron - Role of Nutrient
- Essential for elongation of pollen tubes
- Promotes maturity
- Improves seed set
- Regulates metabolism of carbohydrates
- Facilitates the synthesis of nucleic acids
- Maintains cell wall integrity of roots to reduce beneficial root exudates
- Essential for cell division and development
- Aids in the use of nutrients and regulates other nutrients
- Aids production of sugar and carbohydrates, and is essential for seed and fruit development
- Boron enhances uptake of Ca, Mg, and K, and enables sugar translocation.
Boron - Nutrient in Soil
- Sandy soils receiving excessive amounts of irrigation water, and calcareous soils (pH>8) are at risk of B deficiencies.
Boron - Deficiency Symptons
- Poor seed set or fruit set
- Causes breakdown of growing tip tissue
- Retardation of new growth, followed by death of younger leaves
- At B concentrations 12 ppm or less, terminal buds die and shoot dieback takes place
- Deficiency in alfalfa - yellowish to reddish yellow discolouration of the terminal foliage
- Breakdown of root crops such as beets and turnips, which develop corky dark discolorations
- Rhizobia development in the roots of legumes is inhibited
Boron - Factors Affecting Deficiency
- Low soil moisture
- Coarse textured, well drained, sandy soils and soils with low organic matter can all reduce Boron availability.
- Soil with high organic matter will have greater availability of Boron.
- Soils with high levels of available Calcium may require additional applications of Boron.
- Boron deficiencies decrease the rate of water absorption, root growth, and translocation of sugars in plants.

R3 Agronomic Platform
Roots – The vegetative stage looks to develop vigorous, healthy roots to maximize nutrient acquisition from the soil. The end result is a healthy root rhizosphere.
Reproduce – Supply the essential nutrients at reproduction to help the plant maximize pollen viability, flowering, pollination, seed set and fruit development.
Ripen – Late season nutrition is vital to optimize the nutrient density and quality of the crop.
