As the citrus industry develops towards high yields, high quality, and sustainable growth, fertilizer technology continues to evolve. NPK water soluble fertilizer, one of the most popular and efficient nutrient solutions in modern agriculture, plays an irreplaceable role in citrus cultivation management. Thanks to its fast dissolution, comprehensive nutrition, and high absorption efficiency, it helps farmers achieve the goals of "improving quality, increasing efficiency, stabilizing yield, and achieving early harvest". CHICO's water soluble NPK fertilizer is specially designed for fruit crops, particularly citrus, to meet its nutritional needs during different growth stages.
Water soluble NPK fertilizer is fully soluble, nutrient-rich, and scientifically formulated. It can be quickly absorbed by citrus trees through irrigation or drip systems, effectively meeting the crop's nutritional needs throughout its entire growth cycle:
Fast Dissolution, Good Absorption: Fully water-soluble, residue-free, and compatible with drip irrigation systems, enabling rapid nutrient transfer.
Comprehensive Nutrition: Rich in nitrate nitrogen, phosphorus, potassium, zinc, manganese, and other essential elements, fulfilling the nutritional needs of citrus from rooting to fruiting.
Stimulates Growth: Promotes root vitality, accelerates metabolism, breaks dormancy, and boosts plant growth.
Disease Prevention: Effectively prevents root rot, cold roots, seedling stunting, fruit cracking, and extends the harvest period by 20-30 days.
Improves Fruit Quality: Increases sugar content and vitamin levels, resulting in uniform fruit shape, bright color, and enhanced storage and transportation resistance.

By scientifically applying NPK water soluble fertilizer throughout the citrus growing cycle, farmers can significantly improve tree stress resistance and nutrient use efficiency, greatly enhancing fruit quality and economic returns.
| Growth Stage | Purpose | Recommended Application Method | Function of NPK Water Soluble Fertilizer |
|---|---|---|---|
| Seedling Stage | Promote root growth and improve survival rate | Drip Irrigation/Root Irrigation | Increases root quantity, prevents stunting |
| Flower to Young Fruit Stage | Protect flowers and fruit, reduce fruit drop and deformities | Foliar Spray + Drip Irrigation | Enhances fruit set rate, improves nutrient supply |
| Fruit Enlargement Stage | Promote fruit enlargement, prevent fruit cracking | Drip Irrigation + Fertigation | Stimulates cell division, improves fruit uniformity |
| Color Transition and Maturation Stage | Increase sugar content, improve color | Drip Irrigation/Foliar Spray | Increases vitamin C content, enhances fruit color |
| Post-Harvest Recovery Stage | Supplement nutrients, promote root regeneration | Fertigation/Root Irrigation | Repairs roots, delays aging, improves flower bud quality for next year |

Flexible application of NPK water soluble fertilizer throughout the entire growth cycle ensures precise nutrient regulation, stabilizing citrus production and ensuring abundant harvests.
Citrus trees are typical high-demand, long-fruiting crops, with root systems highly influenced by soil structure and water-fertilizer conditions. CHICO's NPK water soluble fertilizer works synergistically through the following mechanisms:
Enhances Root Vitality: High nitrate nitrogen, zinc, and manganese work together to boost root cell activity, quickly repairing aging or damaged roots.
Activates Plant Metabolism: Effectively stimulates citrus enzyme systems, improving resistance to cold, flooding, and other abiotic stresses.
Promotes Fruit Quality: Increases sugar accumulation, enhances internal content, and improves fruit appearance and shape.
Extends Harvest Window: Balances nutrient absorption, effectively delaying early aging, and enabling fruits to be harvested up to 15 days earlier.
Efficient Nutrient Transport: By using integrated water and fertilizer application systems, nutrients are precisely supplied, with absorption efficiency far exceeding traditional fertilizers.
Scientifically adjusting the use of NPK water soluble fertilizer is an effective way to tackle the challenges faced by the citrus industry, including declining quality, frequent diseases, and market volatility.

To better promote the use of NPK water soluble fertilizer in the citrus industry, the following suggestions are recommended:
Implement integrated water and fertilizer technology, combining drip irrigation or micro-spray systems to improve fertilizer efficiency.
Adjust nutrient ratios based on soil test results to achieve precise fertilization.
Develop fertilization plans based on climatic conditions, enhancing stress management during drought or low-temperature periods.
Strengthen post-harvest fertilization to replenish tree nutrients and ensure a bountiful next season.
By adopting these practices, the citrus industry can significantly improve production quality, sustainability, and overall yield, making the most of NPK water soluble fertilizer's benefits.
