Plowed soil has large clumps which make it very difficult to plant and harvest the crop. In addition, if the seed can be sown because the seed does not have good contact with the soil and can not absorb the necessary nutrients, it will weaken and become a poor quality crop. For this reason, after the initial plowing, which is done by the reversing disc and sub-crusher, and which is done to turn the soil and aeration upside down, these clumps left from the initial plowing should be crushed by softening machines and while creating a suitable shape to the ground. , Provide suitable conditions and substrates for seed growth.pay attention to this issue.
