Forestry: Boron in forestry production

Agronomy Notes

It occurs in many countries, particularly in exotic plantations of eucalypts and pines, but also in plantations and natural stands of native species on soils altered by macronutrient fertilization, liming, fire, or erosion.

Fruit tree foliar nutrient sprays

Agronomy Notes

Foliar nutrient sprays are commonly applied to fruit trees. Boron is immobile in most plant tissues so boron may not be readily transported to developing flower buds. Solubor can be effectively applied with dormant oil-insecticide sprays during the dormant stages of most fruit trees.
