Question

The land levelling implement is known as
A. Patela
B. Roller
C. Scrapper
D. All of the above

Answer 1

Hint: Land levelling refers to the process that guarantees that the profundities and discharge variations over the field are generally uniform and, thus, that water appropriations in the root zone are similarly uniform.

Complete answer:
Land levelling consistently improves the effectiveness and the utilization of water, labour and energy resources. The levelling activity, in any case, can be the most seriously problematic social practice applied to the field and a few variables should be considered before actualizing a land levelling venture.
Option A - Patela is accustomed to smoothening, levelling and moulding the field surface. It is a long rectangular, weighty, plank which consists of locally accessible wood. At times additional weight is added to the plank by setting stones on it when it is used for levelling purposes in the field.
Option B - Rollers or land rollers are used to push down rocks or such debris present on the field to make it smoother for agricultural purposes and also reduce the loss of grain and yield.
Option C - Scrapper is accustomed to levelling the lopsided field, it assists with decreasing soil disintegration and guarantees uniform irrigation for the whole field.
Option D - Patela, Roller and Scrappers, all these three are used to implement land levelling. All these help in preparing the field for agricultural purposes by smoothing and moulding the field.
Thus, the correct answer is option, ‘D. All of the above’.

Note: Levelling, smoothing and moulding the field surface is as essential to the surface framework as the plan of manifolds, laterals, risers and outlet are for trickle or sprinkler irrigation. Laser controlled equipment is also used in land levelling. It results in a more level field and is mostly used in Japan, Australia and the U.S.
