The right boron choice for granular compound fertilizers
When tested for spreadability, Granubor was consistent in every fertilizer spread tested.
Multiple foliar sprays of Solubor applied alone or with insecticides will ensure boron supply during the critical stages of flowering and berry development in grapes. Preplant soil application of Granubor plus foliar sprays of Solubor during the season are recommended for soils testing low in available boron.
Field research comparing boron sources and rates in corn and soy crops show Granubor's effectiveness.
Peanuts require boron, especially during the pod development stage, or “hollow heart” may occur, possibly reducing quality and yields. Read more about how Solubor and Granubor can help ensure adequate boron supply.
