Farmhouse manure can activate the soil, but why do farmers seldom use it now?

Mainly inconvenient, farm manure needs to be transported to the farmland after it is done, which is large and dirty. Although the crops planted in the field are delicious, the particles are relatively small. Another reason is that more and more chemical fertilizers are used and more and more grain is harvested, so chemical fertilizers are widely used.

It's not that people don't want to use farmyard manure, but because of the reform and development of the times, farmyard manure is less now. In the past, every family had a pigsty. Every year they send big fat pigs. One corner of the pigsty is still connected to the toilet, and human excrement, pig excrement and pig urine are all in the pigsty. In order to make pigs comfortable on the fence, they should often go to the fence. It's full of new soil, and farm manure is enough. But since the development of rural reform, we have stopped raising pigs at home, let alone chickens, ducks and geese in the yard. Toilets in our village are all flushed, and there is a unified sewer in the countryside. Septic tanks are unified, and it is not easy to find some farm manure, which is a sign of rural development.

A package 100 kg of chemical fertilizer is equivalent to the fertility of a ton of 2000 kg of farmers' chemical fertilizer. When farmers fertilize, crops can be completed in less than half an hour on an acre of land, while fertilizer on the farm takes half a day. Secondly, the supply of chemical fertilizer is convenient enough. The fertilizer on the farm must go through several processes (such as accumulation, exposure and crushing), and the fertilizer can be purchased and used in the market. Third, feces are smelly and unhealthy after all. If mass production requires a lot of space and has an unpleasant smell, the production cost will gradually increase.

Now there is more advanced and professional organic fertilizer production. Therefore, we changed our minds. On the basis of applying chemical fertilizer, biological fertilizer can be actively applied to adjust the soil, and its effect is the same as that of the original farmyard manure, and the application amount is gradually increased.
