Chicken manure is good for farmland. Why would some people say that it cannot be used?

Abstract: chicken manure has always been a high-quality farm manure, so why can't it be used?

Chicken manure has always been a good farm fertilizer, so let's take a look at the benefits of chicken manure first.

Chicken manure is a very high quality farm manure, which plays a good role in the growth of crops using chicken manure. Chicken manure is rich in organic matter, and the content of nitrogen, phosphorus and potassium is very high. Generally speaking, a portion of chicken manure contains 1.63% nitrogen, 1.54% phosphorus and 0.85% potassium. There is no way to compare cow manure with pig manure at such a high content.

In addition, chicken manure also contains a lot of trace elements, and the mature chicken manure is very suitable for crop application.

Why can't you use so many chicken droppings?

The harm of the application of chicken manure circulated on the Internet is mostly caused by improper operation by users, and like other farm manure, chicken manure must go through the step of ripening before it is used. The harm of unripe chicken manure is not small, but it can not be simply said that chicken manure can not be used.

Without the harm of rotten chicken manure

The most serious problem with unripe chicken manure is that it can cause fertilized crops to burn seedlings. Because after the unfermented chicken manure is buried in the ground, it will ferment as soon as the conditions permit, which will cause root burning in the root of the plant near the chicken manure because of the heating of fermentation. If it is light, the growth of crops will be affected, and in some cases, it will cause crop death.

In addition, when chicken manure is fermented underground, it releases toxic and harmful gases such as methane and ammonia, which is not only not conducive to crop growth, but also more serious to greenhouse crops. And the use of unfermented chicken manure will cause lack of oxygen in the soil and rot the roots of crops.

However, the harm mentioned above is chicken manure that is used without maturity, and chicken manure that is already rotten is two completely different concepts, so it is entirely safe for farmers to use rotten chicken manure.

In addition, for the spread on the Internet about all kinds of harm of chicken droppings, many are nonsense. For example, some people say that chicken manure will cause excessive levels of heavy metals in the soil, and the feed eaten by chickens does contain very small amounts of heavy metals, but this is also necessary to maintain the normal growth of chickens, and the state has special regulations in this respect. and if the heavy metals in chicken manure have exceeded the standard, it is estimated that the chickens have died because of heavy metals. Therefore, the content of heavy metals in chicken manure is absolutely in line with the national standards for heavy metal content.

Secondly, some people say that the hormone content in chicken manure exceeds the standard, and it is undeniable that many unscrupulous businesses will use hormone feed in order to make chickens grow faster. But after the mature chicken manure, the hormones have been broken down, so this harm does not exist.

Others say that there are many parasites, but the chicken manure parasites that have been fermented at high temperature have almost been killed. If you use chicken manure to cause pests on crops, I'm afraid the chicken manure you use is not fermented normally.

So it seems that chicken manure, chicken manure after ripening and fermentation can be used normally, and the effect of chicken manure as base fertilizer is very good.
