When farmers leave plant stalks in the field to reduce soil erosion, it is called ____. a. contour farming c. no-till farming b.
aleksklad [387]

Answer:

Option (C)

Explanation:

In no-till farming method, the farmer usually uses a no-till planter with the help of which they make a narrow type of trench that is sufficient enough for the seed to be grown in rows. The residue of the cover crop is allowed to place on the surface of the soil by not plowing, as a result of which the soil is protected from getting eroded and losing of moisture content. This improves soil quality.

This method helps in increasing the water content that percolates down into the soil, holding the organic matter and recycling of nutrient matters. It also expands the growth and population of microbes in the soil, which provides more nutrients to the soil and increases the fertility of the soil.

Thus, when a farmer leaves plant stalks in the field to reduce soil erosion, then it is known as no-till farming.

Hence, the correct answer is option (C).
