Adequate soil moisture is crucial for which process in nutrient management?

Adequate soil moisture is critical for root uptake by diffusion because this process relies on the presence of water in the soil. Plants absorb nutrients through their roots, where water helps facilitate the movement of nutrients from the soil into the root system. In a moist soil environment, nutrients can dissolve in water and be taken up by root hairs through diffusion, which is the movement of molecules from an area of higher concentration to an area of lower concentration.

Without sufficient soil moisture, diffusion is hampered, making it difficult for plants to access the nutrients they need for growth and development. Dry soil can lead to nutrient stress in plants, as the lack of water restricts the availability and mobility of nutrients. Therefore, maintaining adequate soil moisture levels is vital to ensure efficient nutrient uptake through this essential process.
