Answer:
ALL OF THESE IS CORRECT OPTION.
Detailed Explanation:
a) ORGANIC MANURE - Nutrients present in organic manure are released slowly by decomposition process done by microbes, which improves soil quality.
b) FIELD FALLOW - When we leave the field undisturbed without growing any crop on it, a lot of humus grow in it along with soil bacteria. This way soil becomes rich in nutrients.
c) CROP ROTATION - Crop rotation helps to battle against the forces of erosion. Rotating crops helps to improve soil stability by alternating between crops with deep roots and those with shallow roots. Planting legumes replenishes the soil with minerals.
THUS ALL OF THE ABOVE SUPPORTS IN REPLENISHING THE SOIL BACK WITH ITS NUTRIENTS. So the FINAL ANSWER is "ALL OF THESE".
