Nitrogen, phosphorus, and potassium (NPK) are the three essential nutrients for plant growth and must be replenished through fertilization. Nitrogen is a core component of proteins, nucleic acids, and chlorophyll, promoting leaf growth and photosynthesis. Phosphorus participates in energy transfer and root development, impacting fruit quality. Potassium regulates cellular metabolism and enhances plant resistance to stress.

PRODUCT USES

• Promotes branch and leaf development: Nitrogen is a major component of proteins, chlorophyll, and nucleic acids, significantly increasing leaf number and volume. It is particularly crucial for increasing the yield of leafy vegetables such as cabbage and spinach.

• Enhances photosynthesis: By increasing chlorophyll content, it accelerates the synthesis of organic matter.

• Signs of nitrogen deficiency: Uniform yellowing of older leaves and stunted plants. Excessive nitrogen leads to excessive growth and decreased resistance.

Phosphorus (P) - Key to energy and reproduction

• Root and flower and fruit development: Phosphorus participates in energy transfer (such as ATP synthesis), promoting early and rapid root growth. It also provides energy for flower bud differentiation and fruit ripening, increasing fruit set and accelerating ripening. • Improved stress resistance: Enhances crop tolerance to cold and drought.

• Phosphorus deficiency symptoms: Dark green or purple-red leaves and delayed flowering; excessive amounts may lead to trace element deficiencies.

Potassium (K) – A regulator of quality and resistance

• Improved fruit quality: Promotes sugar and starch accumulation, increasing fruit sweetness and color, particularly effective for tubers (such as potatoes and sweet potatoes) and melons (such as tomatoes and watermelons).

• Enhanced stress resistance: Improves disease and pest resistance, lodging resistance, and regulates water balance.

• Potassium deficiency symptoms: Scorched leaf edges and poor fruit quality; excessive amounts may impair calcium and magnesium absorption.
