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.
