Question

The main function of a cultivator is
(A)To turn the soil
(B)To make a furrow in the soil
(C)To pulverize the soil
(D)All of the above functions

Answer 1

Hint: The main function of a cultivator is to separate the particles of soil from each other rather than breaking the larger soil particles into the smaller ones. It is used before the seed to be sowed or after the crop is harvested.

Complete answer:
The main function of the cultivator is to pulverize the soil. The other function performed by the cultivator is to prepare the soil for the plants which will grow there, but they will also remove weeds from the soil, sculpt the soil into rows and beds and even also improve its structure to permit empty space for air and water to penetrate more easily to the roots of plants.

Additional Information: The difference between a harrow and a cultivator is that a harrow disturbs the total surface of the soil, cultivators are designed in such a manner to disturb the soil in careful patterns, disrupting the weeds and sparing the crops. Cultivators of the toothed type are very similar in form to chisel plows, but they perform a different function. The spikes or teeth of cultivators work near the surface, which was used most of the time to control weed, whereas chisel plow shanks work very deep beneath the surface, breaking up the hardpan. The one more difference is that the cultivating also takes much less power than does chisel plowing.
Small toothed cultivators are pushed and pulled with the help of an individual person i.e only a single person is required and are used as garden tools for small-scale gardening, like for the household's self-use or for small market gardens. Similarly, it is seen that the large-sized rotary tillers combine the functions of both i.e harrow and cultivator into one multipurpose machine.

Note: The basic idea of soil scratching which was used to control the weed was ancient and was finished with mattocks for millennia before cultivators were developed. Cultivators were originally run or moved by draft animals like horses, mules, or oxen or were pushed or drawn by people.
