FBSciences' DriveKP™ provides crucial nutrition at hull-split in an easy-to-handle liquid formulation

Dipotassium phosphate delivers key benefits to almond trees, especially during hull-split timing. Hull-split is a critical growth stage to address any nutrition and crop protection needs of the tree. Hull-split typically occurs at the end of June to the beginning of July across California growing regions. Research has shown that dipotassium phosphate helps reduce hull-rot in a number of ways.

DKP balances nitrogen:
June applications of nitrogen dramatically increase the risk of hull-rot, as fungal micro-organisms are in search of available nitrogen
DKP and boron have been shown to improve nutrient balance during hull-split

High pH reduces fungal growth:
Fungi thrive in acidic conditions with a pH of 3.5-6
DKP is highly alkaline
Hull-split applications of DKP create environments that are unfavorable for fungal growth

DKP reduces fumaric acid production:
Fumaric acid production kills tree tissue and speeds up fungal growth
Even in lower pH environments with higher nitrogen content, DKP reduces the production of fumaric acid

Synergies of DKP properties reduce hull rot:
DKP has been shown to significantly reduce hull rot
DKP is essential to a healthy and successful hull-split

The beginning of hull-split sprays is influenced by the almond variety, weather, and level of tree stress. Trees with higher nitrogen content have a longer period of hull-split. Often, vigorous orchards (such as nonpareil varieties) are grown with minimal stress and higher rates of nitrogen. This can lead to uneven ripening which can increase the risk of insect and disease pressures. Implementing methods such as deficit irrigation and proper nitrogen management can reduce the duration of hull-split, leading to higher yielding harvest.

FBSciences' premium dipotassium phosphate product DriveKP™, built with FBSciences' proprietary biostimulant technology FBS Transit^®, is designed to provide highly mobile, plant-available potassium and phosphorus during periods of increased demand. Potassium helps move sugar from leaves to nuts and contributes to sizing. Research shows that dipotassium phosphate results in healthier plants that are better able to resist diseases like hull rot. DriveKP also contains molybdenum, which is essential for proper nitrogen metabolism. DriveKP not only delivers a nitrogen-free formulation, but also allows the tree to fully utilize the nitrogen present, giving the grower more tools to best manage nitrogen.

Because of its key role in cell elongation, excessive nitrogen can weaken cell walls, making crops more susceptible to fungal and other diseases. DriveKP provides potassium and phosphorus for more balanced nutrition, with molybdenum to help the plant fully utilize nitrogen which leads to a lower incidence of hull rot and spur mortality.
