In our formal farming systems, we used our physical energy and power to work in our farm land, but these days we all rely on chemicals substance that why we can no longer manage our farm land and that is why we need physical energy. The reason why land is getting less in fatal in teams of production is because when the reproduction is more than two to three teams in a particular piece of land the manual of the land will be very weak in sense that the seed will not germinate very well.
And when you already know that with these two or three teams, the soil can have weaknesses that can impact seed growth. You should also have found a better solution for this or you can simply revert to the old method when the yields were very high. Because now there are a lot of agricultural tools and part of it is to help farmers not to exert excessive physical effort, so besides you have to consider the problem of growing your own plant seeds, you also have to look at tools that can make you lighter in using your own power for it.
