comfort, the recent However, even greater than what bothering



reporter recently famous that the current average application rate of fertilizer is a safe application of fertilizers in amplified countries 2 times the upper limit, but the average utilization rate of only about 40%;

year output of about 1.7 million of pesticides tons, an average of almost 18 million acres of farmland needed a couple of pounds per acre;

each year about 500,000 tons of plastic sheeting left in the soil,Gucci Wallet UK, plastic movie rate of 40 %......

These chemical compounds not only contaminated the land,Womens Gucci Casual Trainers, the agricultural water, but also a serious threat to food safety.

do not use a lot of external resources to successfully maintain soil fertility and health. This is a hundred years antecedent Western agronomists discovered the most unbelievable of China's agriculture office. Today, although, China's agriculture is on the road by large industrial fertilizers, pesticides, herbicides, additives, plastic sheeting, and other inorganic to sprinting all the course compelled.

now bogged down in the food security quandary we have not extricate themselves. Experts warn, should reflect our current agricultural production?

about 500,000 tons of plastic sheeting was left in the soil specialist called use and recycling. But the reporter was accused that currently there are about 500,Gucci Trainers,000 tons per year in China plastic residue in the soil, plastic film rate of 40%. Plastic sheeting in agricultural production in large-scale use and does not think its degradation,Womens Gucci Tall Boots, thus production China's ecological context paid a heavy price, to hasten the land of

Jiang G says.

long-term commitment of degraded ecosystems and rehabilitation of degraded farmland Jiang Gaoming, talk to reporters before he was discerned in some rustic areas was almost clear with a white plastic film covering farmland, hillside scene, use white dread

According to Jiang G introduced a large number of residues in the soil in the plastic, not easy in the 15-20 cm soil membrane to fashion pervious, breathable wafer of hard agriculture. The most critical is no way to degrade it. Some research has concluded its life: probably 7 generations, 140 years of degradation also can not afford.

worrying still, in the process of degradation of plastic, there will be carcinogenic dioxin emissions into the atmosphere. For example, some plastic sheeting from diligent planters will elect up afterward the scalding of fields, it seems neat, in fact, low-temperature combustion emissions of extremely toxic dioxins into the farmers' body and the air, and become complicated to obtain rid of the vicious pollutant .

in Jiang Gaoming view, plastic is the most rubbish inventions of modern farming. People use it to be chapter of the increase resulting from dependence. In departure from the orthodox practice of hoeing, not organic manure, fodder and other assist land, covered with plastic sheeting to fulfill the insulation, water retention, weed, moth and other purposes, the surface is not better thing to do, but in truth paid cumbersome cost, in accelerating the land Tantamount to showed a decline, the citizen average of less than 1% of soil alphabetical stuff. At the same time, the measure of fertilizer and the growth rate was also surprising.

According to Jiang G, the multinational recognized safety limit of chemical fertilizer is 225 kg / ha, but our average use of chemical fertilizers per unit area approached 434.3 kg / ha, is 1.93 times the safe limit.

invested from the average application rate of fertilizer to see the chart alteration, the 1950 China hectares (15 acres) of land application of fertilizer more than 8 pounds, now 868 pounds. Hundredfold addition in speed.



heart there is a digit as Jiang G: China's factory-farmed animals generate 2.7 billion tons per year beast wastes, industrial solid garbage is about 3.5 periods. But the isolation of breeding and harvesting and additional reasons, they could have chance quite nice fertilizer, animal fertilizer should no be accustom where. Results

on pesticides, Jiang G available file are: average pesticide application rate of China's 13.4 kg / ha, of which 60 to 70% of the residues in the soil; 2008 total 1.73 million tons of pesticides, the average Mushi and 1.92 pounds of pesticides.

Jiang G's total pesticide use in dynamic diagram shows the aggregate pesticide application in 1990, about 70 million tons, 20 years afterward, this figure has become extra than 170 million tons.

fact, even without chemical fertilizers and pesticides caused by straight contamination, irrigation and other industrial and mining waste water sewage pollution on the land have made it an indirect overwhelmed. Relevant data show that China deserving to contamination of irrigation water up to 3250 mu of cultivated land. At present 70% of the contamination of rill systems, which use 40% of the basic wastage of feature, 95% of the rivers streaming via cities are contaminated.

lawful likewise confessed namely China's arable land, particularly pollution is very solemn. According to the survey, the nation contaminated about 1.5 million mu of arable land, China accounted for about one-tenth of the total space of ​​cultivated land. This insight cries, hold 18 million mu of refined land

contrary to the laws of nature of production intimidate food security

in Jiang G appears dependent on a large number of agricultural chemicals called into the salient functions of the so-called modern agriculture, endangering numerous, unsustainable. It requires not only a large number of mining exploration, fuel, etc., so that increased pollution and greenhouse gas emissions, a massive number of chemicals creature put into arable land, causing land contamination is not conducive to plant growth, crops and even led to harvest failures, also a serious menace to food contamination, food safety. into the body, and persist to collect in the person body. Ultimately guide to assorted diseases. Recently reported,

while the agricultural production emergence of serious problems. shake is contrary to the laws of factory growth.

merely a alike phenomenon opposed to the statutes of nature teem in the agricultural production, just as Jiang G cited: in-season fruit and vegetable production, exacerbated at narcotic residues in agricultural products; animals, , ducks,Gucci Shoes Sale, geese and other birds of the life cycle shortened to 28-45 days,Mens Gucci Sneakers, the pigs dwindled to 2.5-4 months. ambition be problems. Jiang G believes that maintaining the new food production, the pesticides and fertilizers, the application rate at half is sufficient.

the confusion: Our primary source of edible agricultural products, have been subjected apt such a chemical making, industrialization, chemical deputies alternatively non-consumption of toxic and hazardous substances? What do we want apt go?
