Potassium plays a vital role in the development and production of potatoes. Potatoes use a large amount of potassium to carry out metabolic functions such as moving sugars from the leaves to the tubers, and later, the transformation of those sugars into potato starch. Adequate potassium levels increase the specific gravity content, which leads to better frying properties and flavor of the crop.
Potato roots require potassium nearby in the soil because soil potassium is relatively immobile. Since soil potassium levels do not change much during the growing season, nutrients used by the tubers and removed from the soil will cause soil potassium levels to steadily decline. Incorporating a readily available potassium fertilizer such as Intrepid Trio into a balanced fertility program will lead to higher potato yields and quality.
