Some experts say that this farmhouse fertilizer is easy to pollute the dealer, and this does have a certain road. This is indeed the right time, especially for some fungi in farmyard manure that exceed the standard and the heavy metal content is too high. Both of these indices can be tested scientifically, not by experts.
Fermentation of farmhouse manure process.
For traditional farm fertilizer, it is basically made of a mixture of animals, people and crop straw. After fermentation for an indefinite period of time, it is often referred to as farmhouse fertilizer. The key issue in this is fermentation, which itself is a process of mutual conversion of different substances. The bigger factor is that the temperature generated during the fermentation process, and whether this temperature is high or low and whether it lasts for a long time is the key to the elimination of bacteria in the farmyard fertilizer. Because this farmhouse fertilizer is basically fermented in a natural way, no one deliberately controls the effect of this fermentation. This is what experts say that farmers are easy to pollute the farm, that is, they often say that soil diseases are basically in the fertilizer of the farmers here.
Farmyard manure.
Nowadays, farmers farm the land, and many people like to use chicken manure mixed with other manure. There are many reports of excessive heavy metals in these feces. Because these chickens may be fed with excessive amounts of certain elements in their feed, which are metabolized into the chicken manure. The heavy metals in this chicken manure then enter the soil, resulting in soil pollution. This is indeed a big factor for the growers, and it should be seen in the news reports that some vegetables have excessive heavy metal standards. Most of them come from traditional organic fertilizers, which experts say is no problem.
The fermentation is not complete, and the fungus exceeds the standard.
Farmyard manure itself is a very good virgin fertilizer with abundant organic matter. The key is to grasp the fermentation process in the process of making farmhouse fertilizer, and try to control the fermentation time of farmhouse fertilizer for a longer time. It makes the fermentation more sufficient, reduces the content of certain fungi, and is more conducive to the demand of crops.
