Early growth, stem strength, fruit/seed size and plant sugar production are all governed by potassium.
Potassium management is critical in the pursuit of high-production fertility, which is why in-field potassium monitoring can be very productive. Potassium is utilised during fruit and seed filling and is critical to maximising crop yields. However, potassium is often overused in contemporary horticulture and excesses can tie up magnesium and boron. Monitoring sap potassium levels throughout the crop cycle can assist in balancing and optimising potassium application.
