INTRODUCTION
Liquid potassium fertilizers and solid potassium fertilizers are widely used to supply potassium, one of the primary macronutrients essential for plant growth, yield, and quality. Potassium plays a critical role in water regulation, enzyme activation, carbohydrate transport, and stress tolerance. Understanding the characteristics of liquid potassium fertilizers and solid potassium fertilizers helps growers choose the most suitable form for different crops and application systems.
ROLE OF POTASSIUM IN PLANT NUTRITION
Potassium supplied through liquid potassium fertilizers and solid potassium fertilizers supports several vital plant functions:
-
Regulation of water balance and stomatal activity
-
Activation of metabolic enzymes
-
Improvement of photosynthesis efficiency
-
Enhancement of fruit size, color, and quality
-
Increased resistance to drought, salinity, and disease
Adequate potassium availability is essential for balanced crop nutrition and sustainable productivity.
