PLOUGH


Yes it's a good old plough...
Manny people wonder how did old people come up with invention of the plough..whell story goes like this..
When agriculture was first developed, simple hand-held digging sticks or hoes would have been used in highly fertile areas, such as the banks of the Nile where the annual flood rejuvenates the soil, to create furrows wherein seeds could be sown. To grow crops regularly in less fertile areas, the soil must be turned to bring nutrients to the surface. The first people known to plough were the Sumerians.
So why do we turn the soil?

When an animal flesh and plant debris falls on the ground it starts to deteriorate..By that mean it is eaten by bacterias and worms..and when they do that, they leave Calcium and minerals behind them.. which are very good for future plant..
But what if there is no plant or animals for a longer period..that the soil creates its fertile layer..which you need to turn up for the plants you are going to plant :) or seeds
