The prospects for water and fertilizer integration

In recent years, along with the rapid development of the water-soluble fertilizer industry, Xindu Chemicals, Shenzhen Baotian and other companies have improved the technology of water-soluble fertilizer purity and insoluble particle size, which has enabled water-soluble fertilizers and associated facilities to achieve high-speed water and fertilizer integration. development of.

According to Gao Xiangzhao, according to the calculation of the country's 900 million mu of irrigated area, the current application ratio of water and fertilizer integration is only 3.2% and 450 million mu of cultivated land is suitable for the development of water and fertilizer integration.

The potential for water-soluble fertilizer is huge. The output exceeded 2 million tons last year. In the second half of 2012, the compound fertilizer industry was in a boring state. The fluctuations in the price of nitrogen fertilizer and potash fertilizer in the upstream and the uncertainties in the industry outlook kept the fertilizer market from continuing to slump. Gao Xiangzhao pointed out that the prices of coal and natural gas continue to rise, and labor costs and transportation costs have continued to rise. However, the fertilizer market has not shown any upward trend. The end of the year and the beginning of spring are often the peak season of the winter storage market. However, this year's winter storage startup is not ideal, and the enthusiasm of dealers for payment of goods is not high, showing a tendency of delay and reduction.

The overcapacity of compound fertilizers is an indisputable fact. In the next few years, competition will become increasingly fierce. Under the current situation of the depressed agricultural materials market, irrigating fertilizers and water-soluble fertilizers will become an important area for more fertilizer companies to increase their competitiveness.

Regarding industrial development prospects, Li Tie Shen, deputy director of the National Agricultural Technology Extension Service Center, believes that the water-soluble fertilizer meets the overall requirements for the development of the “five in one” development. Water soluble fertilizer is an energy-saving and environmentally friendly fertilizer that can adapt to the development of ecological civilization. trend. Therefore, at this stage, the integration of water and fertilizers to solve the problems of agricultural production will be the first choice, with huge market potential.

Zhang Chenglin, director of the Crop Nutrition and Fertilization Research Unit at South China Agricultural University, said that liquid manure has developed rapidly in countries with high labor costs. U.S. liquid manure accounts for 38% of the total fertilizer and has more than 2,800 liquid fertilizer plants. It consumes 16 million tons of liquid fertilizer annually. France, Australia, Canada, and Mexico are countries that use more liquid fertilizers, and Israel uses water-soluble fertilizers through irrigation systems such as water and fertilizer integration.

In China, the development of water soluble fertilizer market is also relatively rapid. In 2010, the annual output of China's water-soluble fertilizer was 600,000 tons, and in 2011 it was 1.59 million tons. By 2012, the output and use of water-soluble fertilizer had exceeded 2 million tons.

In addition, the number of registrations can also provide insight into the development of the industry. According to statistics from the National Chemical Fertilizer Quality Supervision and Inspection Center, as of January 2013, a total of 4,539 water-soluble fertilizers were registered nationwide, an increase of 32.3% over 2012.

The proportion of water-insoluble matter dropped to 0.5% to avoid plugging facilities. The biggest difference between the new international standard for water-soluble fertilizer chemical industry and the existing agricultural industry standards is that the proportion of water-insoluble matter in solid-liquid and water-soluble fertilizers is set by the agricultural industry. The 5% was reduced to 0.5%.” The deputy director of the National Fertilizer Quality Supervision and Inspection Center (Shanghai) ** commented on the “International Standard for Water-soluble Fertilizers” and caused a stir among participants.

**Said that the integration of water and fertilizer is no longer the traditional sense of irrigation. It is through agricultural facilities that the water-soluble fertilizers (nutrients) are precisely delivered to the crop's absorbable sites. At present, the agricultural facilities are not only large-scale and fixed, and therefore, the irrigation facilities require more fertilizer than ever before. If the fertilizer used does not meet the requirements, and the dripper or sprinkler is clogged, the maintenance is difficult and therefore the fertilizer used can only be controlled. In Israel, the ratio of insoluble water-soluble fertilizers is limited to between 0.1% and 0.3%. According to the standards of the Ministry of Agriculture, the proportion of water-insoluble matter is set at 5%. When such water-soluble fertilizers are used for drip irrigation and sprinkler irrigation, the drippers and sprinkler heads can be easily blocked.

It is reported that the market for water soluble fertilizers is currently chaotic. There are numerous manufacturing companies, and the brands are disordered. The effects are uneven. Once farmers use water-based fertilizers that are damaged, they will have an overall distrust of water-soluble fertilizers.

Zhang Chenglin stated that water-soluble fertilizers impose higher requirements on the production and use of technologies. For example, when farmers use water-soluble fertilizers, they must first understand the choice of suitable irrigation facilities, use small amounts and pay more attention, pay attention to nutrient balance, and secondly, understand the water quality and rationally use irrigation equipment. .

Water and fertilizer integration In 2015, the production and application of 50 million mu of water-soluble fertilizer was newly added. Compared with conventional fertilizers, the technological content is more demanding. On the one hand, the quality of water-soluble fertilizers is relatively high, especially the content and granules of insolubles. The size needs to be strictly controlled; on the other hand, injecting water-soluble fertilizers through the irrigation system requires technical services, equipment support, etc. to keep up with it. If water-soluble fertilizers are packed in plastic buckets (or special liquid fertilizers are transported), they can be distributed through the factory-distribution station-field large-scale model, which can reduce costs, and at the same time solve problems such as quality of farmers, lack of technical support, and high prices.

Liu Xiaoxia, vice president of Xindu Chemicals, said that the water-soluble fertilizer meets the requirements of modern fertilization concepts for fertilizers. Before the fertilization was based on the soil, the water-soluble fertilizer was determined by the crop, what the crop needs, and what they provided.

In March 2013, the General Office of the Ministry of Agriculture issued the “Guidelines for Water and Fertilizer Integration Technical Guidelines”. According to the opinions, by 2015, the total area for the promotion of water and fertilizer integration technology will reach 80 million mu or more, and the newly promoted area will exceed 50 million mu. , to achieve more than 50% water saving, fertilizer production 30% food crops increase production of 20% economic crops to increase income more than 600 yuan.

According to crops, the newly added corn water and fertilizer integration technology will cover an area of ​​15 million mu, 500 million mu of wheat, 5 million mu of potato, 5 million mu of cotton, 8 million mu of vegetables, 10 million mu of fruit trees, and 2 million mu of other crops. Among them, the integration of water and fertilizer technology for fruit trees, vegetables, and sugar crops was promoted in East China, Central China, South China, and Southwest China, adding 12 million mu.

At the forum, Vice Minister Zhang Zhangliang of the Guangxi Zhuang Autonomous Region stated at the speech that Guangxi, as a large agricultural region (province), had a 17% increase in the proportion of GDP to GDP, which was 70% higher than the national level and promoted the development of modern agriculture to Guangxi. important. As one of the major agricultural growing areas in China, Guangxi has a sugarcane planting area of ​​16.2 million mu, a yield of 70 million tons (cotton pressing capacity of 7 million tons), accounting for more than 60% of the country; fruit planting area of ​​more than 1,500 acres, annual output of over 10 million Tons, of which bananas and oranges accounted for more than 60% (of which citrus and banana planting areas are ranked second in the country), the cultivation of these crops are inseparable from chemical fertilizers. “In Guangxi, there are 15 million mu of dry land, accounting for 40% of the total concentration in the mountainous areas of western Guangxi and northwest Guangxi. Therefore, Guangxi needs water-saving irrigation projects.”

The Ministry of Agriculture stated that by 2015, water and fertilizer integration will achieve more than 50% water saving.
