Which field will likely have soil with high nutrients for growth of new plants in the third season?
A. Field 1 as cultivating same crops every season increases productivity of the crops
B. Field 2 as cultivating different crops reduces the water requirement of crops
C. Field 1 as cultivating the same crops requires only same type of nutrients
D. Field 2 as cultivating different crops restore the nutrients in the field
Answer (2)
Field 2 is likely to have higher nutrients for new plant growth due to the practice of crop rotation, which helps restore nutrients in the soil. In contrast, Field 1, which follows monoculture, can deplete soil nutrients over time. Therefore, the correct option is D.

The subject of this question is related to agricultural practices, specifically focusing on crop cultivation and soil nutrients. In farming, choosing the right crop rotation strategy is crucial for maintaining soil fertility and ensuring the long-term success of crop yields.
Here's a step-by-step explanation of the concepts involved:
Monoculture vs Crop Rotation:
Field 1 refers to a scenario where the same crops are cultivated every season, known as monoculture. This practice can lead to soil nutrient depletion because each season, the same type of nutrients is consistently being used up by the same crops.
Field 2 involves cultivating different crops each season, a practice known as crop rotation. This method helps in maintaining healthy soil by replenishing nutrients that may be depleted by the previous crop.
Nutrient Depletion and Restoration:
When the same crop is grown repeatedly (Field 1), it can exhaust specific nutrients in the soil. This affects soil fertility negatively and can lead to reduced crop productivity over time.
Cultivating different crops (Field 2) helps restore nutrients naturally. Different crops have varying nutrient requirements and can contribute different organic matter to the soil, which can enhance nutrient profiles.
Why Crop Rotation Is Beneficial:
Crop rotation can break pest and disease cycles and improve soil structure and organic matter content. This, in turn, increases the soil's ability to retain moisture and support crop growth, thereby making it a sustainable practice.
Based on this understanding, the correct answer is (d) Field 2 as cultivating different crops restore the nutrients in the field .
