Ques: Q: What is the purpose of utilizing careful farming practices such as rotating crops or planting nutrient rich crops? Read this paragraph and choose the correct option from the provided answers: Careful farming helps to keep up soil quality each season. One way is to plant different crops each year. Another is to alternate the crops planted in each row of the field. These techniques preserve and replenish soil nutrients. Planting nutrient rich cover crops helps the soil. Planting trees as windbreaks, plowing along contours of a field, or building terraces into steeper slopes all help to hold soil in place ( Figure below ). No-till or low-till farming disturbs the ground as little as possible during planting. Choices: - improve sediment quality - improve photosynthesis quality - improve soil texture - improve soil quality A:
Ans:
improve soil quality
