In recent years, the water-soluble fertilizer industry has experienced rapid growth. Companies such as Xindu Chemicals and Shenzhen Baotian have made significant technological advancements in improving the purity and particle size of insoluble components in water-soluble fertilizers. These innovations have enabled high-efficiency integration of water and fertilizer, driving the development of this sector.
On March 30th, during the Fourth China International Water-Soluble Fertilizer High-Level Forum and Functional Liquid Fertilizer Symposium held in Nanning, Guangxi, Gao Xiangzhao, Director of the Water Saving Department at the National Agricultural Technology Promotion Center, emphasized that "The era of traditional fertilizers is over, and a new era of water-soluble fertilizers is coming." This statement was widely accepted by over 300 participants, including experts, company representatives, and agricultural distributors.
According to Gao Xiangzhao, with 900 million mu of irrigated land nationwide, the current application rate of water and fertilizer integration is only 3.2%, leaving 450 million mu of farmland with great potential for development.
The market for water-soluble fertilizers shows enormous promise. Last year alone, output exceeded 2 million tons. However, the compound fertilizer industry faced challenges in 2012, with price fluctuations in upstream nitrogen and potash fertilizers and uncertain market conditions leading to a stagnant market. Rising coal and natural gas prices, along with increasing labor and transportation costs, failed to drive fertilizer prices upward. Typically, the winter storage season marks a peak in demand, but this year saw weak performance, with dealers showing reluctance to pay for goods, indicating a trend of delayed and reduced orders.
With overcapacity in compound fertilizers, competition is expected to intensify in the coming years. In the current slow agricultural capital market, water and fertilizer integration is becoming a key area for companies to enhance their competitiveness.
Li Tie Shen, deputy director of the National Agricultural Technology Extension Service Center, believes that water-soluble fertilizers align with the overall goals of the "five in one" development strategy. As an energy-efficient and environmentally friendly option, they support the trend of ecological civilization. At this stage, integrating water and fertilizer to address agricultural challenges is seen as the top priority, with massive market potential.
Zhang Chenglin, director of the Crop Nutrition and Fertilization Research Unit at South China Agricultural University, noted that liquid manure has developed rapidly in countries with high labor costs. In the U.S., liquid manure accounts for 38% of total fertilizer use, with over 2,800 plants producing 16 million tons annually. Countries like France, Australia, Canada, and Mexico also rely heavily on liquid fertilizers, while Israel uses water-soluble fertilizers through irrigation systems.
China’s water-soluble fertilizer market has grown quickly. Output reached 600,000 tons in 2010, 1.59 million tons in 2011, and surpassed 2 million tons in 2012. The number of registered products also reflects this growth: as of January 2013, 4,539 water-soluble fertilizers were registered nationwide, up 32.3% from 2012.
A key improvement in the new international standard for water-soluble fertilizers is the reduction of water-insoluble matter from 5% to 0.5%. This change aims to prevent clogging in irrigation systems. According to the National Fertilizer Quality Supervision and Inspection Center (Shanghai), this adjustment has sparked discussion among forum participants.
Water and fertilizer integration no longer refers to traditional irrigation methods. Instead, it involves precisely delivering nutrients to crops through advanced agricultural facilities. With large-scale and fixed systems, the demand for high-quality fertilizers has increased. If the quality is poor, clogging can occur, making maintenance difficult. In Israel, the limit for insoluble matter is set between 0.1% and 0.3%, whereas China's standard allows up to 5%.
Currently, the water-soluble fertilizer market is somewhat chaotic, with many manufacturers and disorganized branding. The effects vary, and if farmers encounter low-quality products, it could lead to distrust in the entire sector.
Zhang Chenglin pointed out that using water-soluble fertilizers requires more technical knowledge. Farmers must choose appropriate irrigation systems, apply small amounts carefully, maintain nutrient balance, and understand water quality to optimize results.
By 2015, the newly added area for water and fertilizer integration is expected to reach 50 million mu. Compared to conventional fertilizers, this technology demands higher standards. The quality of water-soluble fertilizers, especially in terms of insoluble content and granule size, must be strictly controlled. Additionally, injecting these fertilizers into irrigation systems requires technical support and equipment.
Liu Xiaoxia, vice president of Xindu Chemicals, said that water-soluble fertilizers align with modern agricultural concepts. Unlike traditional soil-based fertilization, they provide exactly what crops need, enhancing efficiency and sustainability.
In March 2013, the Ministry of Agriculture issued guidelines promoting water and fertilizer integration. By 2015, the target was to promote this technology across 80 million mu, with over 50 million mu newly added. The goal includes saving more than 50% of water, reducing fertilizer use by 30%, and increasing grain yields by 20%, while boosting economic crop income by 600 yuan per mu.
For different crops, the newly added areas include 15 million mu for corn, 50 million mu for wheat, 5 million mu for potatoes, 5 million mu for cotton, 8 million mu for vegetables, 10 million mu for fruit trees, and 2 million mu for other crops. In eastern, central, southern, and southwestern China, the focus is on fruit trees, vegetables, and sugar crops, adding 12 million mu.
At the forum, Vice Minister Zhang Zhangliang of Guangxi emphasized the importance of modern agriculture in the region. With a sugarcane planting area of 16.2 million mu and a yield of 70 million tons, Guangxi plays a crucial role in national agriculture. The province also has a vast area of fruit cultivation, with bananas and oranges accounting for over 60% of production. These crops depend heavily on chemical fertilizers.
Guangxi has 15 million mu of dry land, concentrated in mountainous regions. Therefore, the development of water-saving irrigation projects is essential for the region's agricultural progress.
A hydraulic hose is a flexible tube made of synthetic rubber, thermoplastic or reinforced with wire or textile braid. It is used to transmit hydraulic fluid under high pressure to various hydraulic components such as cylinders, valves, and pumps. Hydraulic hoses are designed to withstand high pressure, extreme temperatures, and various types of fluids, including oil, water, and hydraulic fluids. They are commonly used in industries such as construction, agriculture, mining, and manufacturing. Hydraulic hoses come in different sizes, lengths, and pressure ratings to suit different applications.
