Chicken manure has many benefits for farmland, so why do some people say it cannot be used?
Summary: Chicken manure has always been a high-quality farmyard manure, so where does the claim that it cannot be used come from?
Chicken manure has always been a very good farmyard fertilizer. Here, let us first look at the benefits of chicken manure.
Chicken manure is a very high-quality farmyard manure and plays a very good role in the growth of crops that use it. Chicken manure contains rich organic matter, and the content of the three elements nitrogen, phosphorus and potassium is very high. Generally, one portion of chicken manure contains 1.63% nitrogen, 1.54% phosphorus and 0.85% potassium. Such high content cannot be matched by cow manure or pig manure.
In addition, chicken manure also contains a large amount of trace elements. After decomposition, chicken manure is very suitable for application to crops.
With so many benefits, how could chicken manure be unusable?
As for the harms of chicken manure application circulating online, I personally believe that most are caused by improper operation by users. Like other farmyard manures, chicken manure must go through the step of decomposition before application. The harm of chicken manure that has not been decomposed is naturally considerable, but this does not mean that chicken manure simply cannot be applied.
The harms of chicken manure that has not been decomposed
The most serious problem with undecomposed chicken manure is that it can cause seedling burn in the fertilized crops. Because chicken manure that has not been fermented, once buried underground, will ferment when conditions allow. At that time, heat generated by fermentation will cause root burn near the plant roots close to the chicken manure. In mild cases, crop growth is affected; in serious cases, it can cause crop death.
In addition, when chicken manure ferments underground, it releases toxic and harmful gases such as methane and ammonia, which are not only detrimental to crop growth but even more harmful to greenhouse crops. Moreover, undecomposed chicken manure after use can cause soil oxygen deficiency and root rot in crops.
However, the harms mentioned above all refer to chicken manure used without decomposition, which is completely different from already decomposed chicken manure. Therefore, farmers can completely rest assured when using decomposed chicken manure.
In addition, many of the various harms of chicken manure circulating online are simply groundless. For example, some people say that chicken manure causes heavy metal content in soil to exceed the standard. The feed eaten by chickens does contain very trace amounts of heavy metals, but this is also necessary to maintain the normal growth of chickens, and the state has specific regulations in this regard. Moreover, if the heavy metals in chicken manure had already exceeded the standard, the chickens themselves would probably have died from excessive heavy metals. Therefore, the heavy metal content in chicken manure absolutely meets the state's required standards for heavy metal content.
Second, some people also say that the hormone content in chicken manure exceeds the standard. It cannot be denied that many unscrupulous merchants use hormone-type feed to make chickens grow faster. But after decomposition, the hormones in chicken manure have already been broken down, so this harm does not exist.
Some people also say that there are many parasites, but after high-temperature fermentation, the parasites in chicken manure have mostly been killed. If using chicken manure causes pest problems in crops, then the chicken manure you used probably was not properly fermented.
