Land Preparation
Muhtasari
Before a single seed goes into the ground, a farmer has already done much of the work that decides the harvest. Land preparation is the set of jobs that turn rough or weedy ground into a clean, crumbly seedbed where seeds can germinate and roots can spread. Get it right and the crop comes up evenly, smothers fewer weeds and reaches the water and nutrients it needs. Get it wrong and even the best seed struggles.
In this lesson you will learn how new land is opened up by stumping and clearing, and then how the soil itself is worked. You will see the difference between primary cultivation, the first deep working that ploughing or digging gives, and secondary cultivation, the lighter harrowing or raking that breaks the clods into a fine tilth. You will learn what each operation does to the soil and why the order matters, whether the work is done by hand or by machine.
Malengo
