What color is NPK fertilizer?
The variant of a fertilizer can be identified by its color. There are 3 types of fertilizers such as NPK fertilizer, Calcium fertilizer and Potassium fertilizer. These fertilizers have different colors. NPK fertilizer has blue color, Calcium fertilizer has yellow color and Potassium fertilizer has red color. Whether you’re a small-scale gardener or a large-scale farmer, understanding the types of NPK fertilizers—organic, inorganic, and water-soluble—can help you make better decisions for soil health, plant growth, and crop yield.BLUE. NPK is a high-analysis, broad-spectrum fertiliser, featuring a balanced blend of major plant nutrients and vital trace elements. Replenishing depleted soils, it fosters healthy, vigorous growth across a variety of plants.Blue fertilizer is one of the most widely used types of water-soluble compound fertilizers, recognizable by its distinct blue color, which comes from its rich composition of essential nutrients—primarily nitrogen, phosphorus, and potassium (NPK)—in addition to micronutrients like zinc, iron, and magnesium.Manufacturers use colors for several purposes, including distinguishing between chemical formulations. For instance, blue is often associated with nitrogen-rich fertilizers, yellow with potassium-based ones, and green with micronutrient-rich or organic fertilizers.
What is the use of NPK blue?
NPK is a high-analysis, broad-spectrum fertiliser, featuring a balanced blend of major plant nutrients and vital trace elements. Replenishing depleted soils, it fosters healthy, vigorous growth across a variety of plants. NPK 10-26-26 fixes the phosphorus and potassium content in the soil and is highly effective in soils with leaching condition. The product is granular and comes in moisture resistant HDP bags allowing easy handling and storage.NPK 0-52-34 is a powerful fertilizer that plays a crucial role in improving flowering and fruit setting in orchards and gardens. The high phosphorus content encourages healthy flower formation, while the potassium boosts fruit development, quality, and disease resistance.One of the long-term consequences of excessive NPK fertilizer is soil toxicity. Over time, nutrients accumulate beyond the crop’s absorption capacity, leading to: High soil salinity from nitrate and potassium salts. Soil acidification caused by ammonium-based nitrogen fertilizers.NPK 12-12-17 fertilizer can be used in both indoor and outdoor gardening settings. NPK blue granulated fertiliser can be used to correct nutrient deficiencies in soil, boost yields and improve the quality of crops.The ideal NPK ratio for flowering and fruiting plants focuses on providing high levels of phosphorus and potassium while keeping nitrogen at moderate levels. Ratios like NPK 10-30-20 or NPK 5-15-30 offer the perfect balance of nutrients to support healthy blooms and high-quality fruits.
How to use NPK blue fertilizer?
Directions for use: FLOWERS: Use 30g of NPK Blue Special per m2 by digging into the flower bed and watering in well. Repeat application every 4-6 weeks. FRUIT and VEGETABLES: Prepare the ground by adding 30g per m2 of soil and watering in well. Repeat application every 4-6 weeks. Application Frequency Guidelines NPK 20 20 20 Fertilizer: Apply every 4-6 weeks during the growing season for balanced nutrient uptake and sustained plant growth. NPK 00 52 34: Apply at key growth stages, such as transplanting, flowering, and fruiting, to support root development and reproductive growth.A water-soluble fertilizer with an optimum combination of Nitrogen, Phosphorous, Potassium, and Sodium. It is readily soluble in water and is best for drip irrigation and foliar application of fertilizer. This combination is suitable for almost all crops and can be used along with pesticides and fungicides.This balanced NPK ratio makes it a versatile option, supporting plants during both vegetative growth and flowering stages.
