Boron in Fertilizer APplications

Differences in boron fertilizer sources

Differences in boron fertilizer sources

Growers should know the relative boron needs for each specific crop, as well as the water soluble available boron supply in the soil, to determine the optimum rate and method of applying sufficient boron for optimum yields.

Solubility of Solubor in liquid fertilizers

Solubility of Solubor in liquid fertilizers

Solubor is an excellent boron source for inclusion in liquid fertilizers because it is readily soluble and does not react with other components of these fertilizers.

Amounts of Solubor to mix into spray tanks to supply desired boron rates

Amounts of Solubor to mix into spray tanks to supply desired boron rates

Solubor is highly water soluble, and is commonly applied in foliar sprays. Because the season for the most effective foliar application of boron is short, foliar sprays must be prepared quickly and accurately.

Relative plant tolerance to available boron supply

Relative plant tolerance to available boron supply

Boron nutrition is a special concern in crop production; growers want to ensure that the available boron supply is sufficient for optimum nutrition but not so high as to result in reduced yields from an over-supply.

How much will increased pH affect pesticide efficacy?

How much will increased pH affect pesticide efficacy?

The efficacy of some pesticides may be affected by increased pH of the pesticide tank mixes. Inclusion of an appropriate buffer to control the pH of tank mixes is suggested for those pesticides whose efficacy is known to be reduced by increased pH.
