What is the effect of potassium fertilizer?

If K is deficient or not supplied in adequate amounts, it stunts plant growth and reduces yield. For perennial crops such as alfalfa, potassium plays a role in stand persistence through the winter. Other roles of K include: Increases root growth and improves drought resistance.

Why is too much potassium bad for plants?

As important as it is, too much potassium can be unhealthy for plants because it affects the way the soil absorbs other critical nutrients. Lowering soil potassium can also prevent excess phosphorus from running into the waterways where it can increase growth of algae that can eventually kill aquatic organisms.

Potash is an impure combination of potassium carbonate and potassium salt.
