Over the years, chemical fertilizers have played a vital role in boosting food production and addressing the basic needs of over 1.3 billion people. However, their excessive use has led to severe consequences, such as soil degradation, declining crop quality, and significant non-point source pollution. As society increasingly embraces the concept of "green agriculture" and "eco-friendly agricultural products," replacing a portion of chemical fertilizers with organic alternatives has become a growing trend in modern farming. For fertilizer manufacturers, this shift represents a promising business opportunity amid rising market competition.
Organic fertilizers are typically categorized into three main types: special organic fertilizers, bio-organic fertilizers, and bio-organic-inorganic compound fertilizers. They were first developed in the United States, with large-scale industrial production beginning in the mid-1970s. Today, nearly 2,000 companies worldwide are involved in organic fertilizer production, while in China, there are only over 30 such companies, indicating a huge potential for growth.
China possesses vast amounts of organic waste, including approximately 2.5 billion tons of livestock manure, 700 million tons of straw, 200 million tons of forestry waste, 35 million tons of rice husk, 4 million tons of sugar sludge, and 20 million tons of cake fertilizer annually. Additional materials like bagasse add up to around 3.5 billion tons, ensuring a stable supply of raw materials for organic fertilizer production. This abundance means that the industry is unlikely to face a material bottleneck in the near future.
Despite this, the current usage of organic fertilizers in China accounts for less than 30% of total fertilizer consumption. According to soil fertility studies, an optimal ratio of 2:1 between organic and chemical fertilizers can maximize efficiency, improve soil structure, maintain organic matter levels, and enhance crop resistance to pests and diseases. In 2004, China used 46.37 million tons of chemical fertilizers. If we follow the 2:1 ratio, over 90 million tons of organic fertilizer (in pure nutrients) would be required. However, the current production capacity of organic fertilizers in China is below 1.5 million tons, highlighting a massive gap between demand and supply.
This imbalance presents a huge market opportunity, but challenges still exist. First, chemical fertilizers are known for their quick results and ease of use, which makes them popular among farmers. Organic fertilizers, on the other hand, may not deliver immediate benefits, making it harder for producers to see short-term gains. Second, most Chinese organic fertilizer companies operate on a small scale, with production capacities under 50,000 tons per year. This leads to higher costs and limited brand recognition, reducing their competitive edge. Third, over 70% of organic fertilizer raw materials come from livestock manure, which is often collected from small, scattered farms, increasing collection and transportation costs. Finally, the lack of clear quality standards and weak regulatory oversight allows counterfeit products to flood the market, undermining consumer trust.
Experts believe that despite these challenges, the long-term development of organic fertilizers in China is inevitable. With government support and growing market demand, the sector will eventually gain more attention and popularity. Fertilizer producers who recognize this trend now will be well-positioned to lead the next wave of agricultural transformation.
Vibrating Sieve
The rotary vibrating screen uses a vertical vibration motor as the excitation source. Eccentric weights are installed on the upper and lower ends of the vibration motor to convert the rotational motion of the vibration motor into horizontal, vertical, and tilted three-dimensional movements. Movement is transmitted to the screen surface. Adjusting the phase angles of the upper and lower ends can change the movement trajectory of the material on the screen surface.
