Zero tillage got successful because of?

Correct option is B

Zero tillage is an agricultural practice where the soil is left undisturbed or minimally disturbed during the planting of crops. It has gained success primarily due to the use of herbicides. Here’s a brief explanation:
Herbicides: In zero tillage, the use of herbicides is crucial for controlling weeds without the need for extensive soil tillage. By applying herbicides, farmers can suppress or eliminate weeds, preventing them from competing with crops for nutrients, water, and sunlight.
Reduced Soil Disturbance: Zero tillage aims to reduce soil disturbance compared to conventional tillage methods. Herbicides play a key role in weed management without the need for plowing or other forms of soil movement.
Conservation of Soil Structure: Zero tillage helps in conserving the structure of the soil, reducing erosion, and improving soil moisture retention. By relying on herbicides, farmers can manage weed growth without disrupting the soil, leading to improved overall soil health.
Cost and Time Savings: Zero tillage can result in cost and time savings for farmers, as it eliminates or reduces the need for multiple passes with tillage equipment. Herbicides contribute to the efficiency of this practice by providing effective weed control.
