Show Answers

Applying NPK fertilizers in balanced amounts tailored to specific crop requirements.Implementing appropriate crop rotation involving alternating shallow and deep-rooted plants within a growing season.Consistently incorporating farmyard manure, compost, acidic mulches, green manures, and organic fertilizers to boost soil organic matter.All the above methods combined.None of these.

Explanation

Balanced application of NPK fertilizers ensures crops receive necessary nutrients without harming soil health. Crop rotation with varied root depths prevents nutrient depletion and improves soil structure. Adding organic materials like farmyard manure and compost increases the soil's organic matter content, enhancing fertility and physical condition. Therefore, integrating all these approaches collectively supports sustainable soil management.
