LUMA-PHOS provides linear availability of the nutrients. LUMA-PHOS promotes rooting, therefore should be used after seeding, sodding or after dormancy break in the spring. Wet conditions in the spring reduce potassium availability. High calcium or magnesium levels limits uptake of potassium. Increased levels of potassium help to reduce the severity of damage from most disease causing fungi.
Potassium promotes rooting, enzyme activation and carbohydrate metabolism.
Potassium increases heat, cold and drought hardiness, wear tolerance, disease and nematode resistance.
