Solubor 20.5% Boron - Water Soluble Powder - Organic - 50 Pound (44/Plt)

The best choice for foliar applications, OMRI listed Solubor is formulated to disperse quickly in liquid, leaves minimal residue, and provides an economical source of boron. Solubor combines the highest boron concentration with the maximum possible dispersion and solubility in water, making it ideal for use in agro-industrial markets and farm sprays.

Background: Boron is one of seven micronutrients essential to all plant growth. Its role was recognized first in the 1920s and since that time, boron deficiency has been recognized in a wide range of crops.

Correcting boron deficiency: Boron deficiency can be remedied by the correct application of a borate containing material in solid or liquid fertilizers, to the seedbed in annual crops or under the foliar canopy of perennial crops. Perennial and annual crops can also be sprayed with boron containing solutions. These are normally tank mixed with other micronutrients or with agrochemical products.

The latter method of application may be preferable since at peak requirement times the boron needs of the growing plant can frequently exceed its ability to obtain its needs through the roots. Mixing with other sprays as part of a program enables the grower to time this availability and save application cost.

Detecting boron deficiency: Boron deficiency shows in clearly defined ways in certain crops. Generally, by the time visible symptoms are seen, yields will already have been adversely affected. The best way to establish need is either through soil testing or through tissue analysis. In this way, boron supplementation can form part of a ‘balanced nutrition’ approach to
crop fertilization.

Predicting boron deficiency: Certain crops worldwide are known to be more susceptible to boron deficiency than others. These are shown in the tables.
