INTRODUCTION
Liquid potassium fertilizers are widely used in modern agriculture due to their high solubility, rapid plant availability, and compatibility with fertigation and foliar feeding systems. Potassium (K) is an essential macronutrient responsible for enzyme activation, water regulation, carbohydrate transport, and stress resistance in plants. Proper liquid potassium fertilizer production and well-designed formulas ensure efficient nutrient uptake and consistent crop performance.
ROLE OF POTASSIUM IN PLANT GROWTH
Potassium fertilizers play a vital role in both vegetative and reproductive growth stages.
-
Regulates water balance and stomatal activity
-
Enhances photosynthesis efficiency
-
Improves fruit size, color, and quality
-
Increases resistance to drought, frost, and diseases
Adequate potassium nutrition is critical for yield stability and crop quality.
TYPES OF LIQUID POTASSIUM FERTILIZERS
POTASSIUM NITRATE BASED LIQUID FERTILIZERS
These formulations provide both potassium and nitrogen.
