Can not pursue a high concentration of fertilizer

China is one of the world's population and resource conflicts are most acute. We use the world's arable land 9% and 6% of the water to feed 21 percent of the world's population. But in summary great achievements and experiences, we should be aware of the risks which are inherent. For example, the amount of fertilizer to feed our global population of 1/5 of which use is now close to the world's total amount of 1/3. Unreasonably large number of chemical fertilizer, causing environmental pollution, soil and crop nutrient imbalance and other serious problems.

Base in the country's food basket started earlier in Shouguang balanced fertilization, soil improvement, has made certain achievements. But a recent survey, Shouguang accumulation in soil fertilizer, pesticide residues showing more obvious than the shallow depth of the situation. Why is this? Liu Shouguang Vegetable Station of meritorious said surface of fertilizers, pesticides and slowly downward penetration has now reached 20 meters underground pollution is actually caused 10 years ago. In order to completely remove these contaminants, will probably take longer.

The past 10 years, our experts are from the government to promote the development of high concentrations of fertilizer in. Although high concentrations of fertilizer with a high nutrient content, nutrient elements many advantages, but the blind pursuit of high concentrations will cause some problems. Adsorption capacity of the soil as fertilizer bearing continue to lower, resulting in a huge loss of fertilizer, combined with farmers applying unreasonable, excessive water ammonia, total phosphorus exceeded, water eutrophication, soil contamination will be more serious.

Blind pursuit of high concentrations of fertilizer, as to eat crops eclipse, a long time, soil and crop nutrient imbalance highlighted. Meanwhile, the high concentration of compound fertilizer meant to consume large amounts of high-grade phosphate rock, huge pressure on resources. Too much emphasis on high concentrations of fertilizer is not conducive to increasing farmers' income. Due to the high concentration of fertilizer superstitious peasants will bring high yield, high efficiency, content of 45% or less of the fertilizer has nobody cares. The high concentration means high consumption of raw materials and high production costs, in the case of high-input farmers may not be able to achieve high efficiency, the opposite may also destroyed farmland, pollute the environment.

We can say that in our country a high concentration of fertilizer is artificially overstating it. Fertilizer compound fertilizer industry launched a high concentration of the Great Leap Forward, that is now, if the company did not develop a three to five new high concentrations of fertilizer, are embarrassed to talk about development, about the innovation. Superphosphate, calcium magnesium phosphate, TSP, and a number of low concentrations of fertilizer products are low-end and marginalization. Today, we have formed the ideological stereotype: the high concentration represents the high-end, represents the advanced; low concentration means backward, subject to the policy to suppress and market exclusion. As everyone knows, the main fertilizer varieties developed Western countries today is about 40% of the content of the concentration of fertilizer, in addition to nitrogen, phosphorus and potassium, but also leaving room for other trace nutrients, so more conducive to nutritious crops.

The method can now solved the problem of acidification is rational fertilization and southern Adding FCMP. FCMP is China with independent intellectual property rights, the only alkaline chemical fertilizers, whose production and use of low-grade phosphate rock, to help address the growing shortage of phosphorus resources. 10 years ago, loved by farmers FCMP, errors due to lead the market, has been difficult to find living space. In northern China there are lots of alkaline soil, alkaline soil can be well improved superphosphate are becoming increasingly marginalized. In fact, as an adaptation of superphosphate phosphate resources, soil conditions, crop growth and market needs traditional varieties, is absolutely necessary to keep down long-term, long-term lack of relevant national standards very wrong.

To the low concentration of fertilizer a little space, remove worn on its head "low backward" hat, you need the right guidance and government policy standards. In my opinion, the current focus of the work of fertilizer or fertilizer should be placed on improving the level of science, technology and improve the promotion of balanced fertilization fertilize ideas. To this end, the whole industry to work together, border clearance science, philosophy out of misunderstanding, and even breaking the barriers of interest.
