The liquid fertilizer station system developed by Guangdong Greenstar Biotechnology Co., Ltd. has recently obtained a utility model technology patent certificate issued by the State Intellectual Property Office. The system greatly reduces the costs of storage, handling, packaging and circulation, and the fertilizer barrels can be recycled, which is safe and environmentally friendly.
With the gradual popularization of water and fertilizer integration technologies in China, liquid fertilizers are increasingly accepted and recognized for their uniform nutrient composition and high activity, flexible formulations, simple production, ease of use, wide source of raw materials, and low price. However, the storage and transportation of liquid fertilizer in China is still based on plastic packaging, which increases the cost of liquid fertilizers. Moreover, the plastic packaging bags of these liquid fertilizers cannot be degraded, and are likely to cause environmental pollution.
