What factor is critical for the effective uptake of fertilizer elements?

• A. Soil temperature
• B. Soil texture
• C. Sunlight exposure
• D. Adequate water

Answer: (D)

For effective uptake of fertilizer elements, adequate water is essential because it facilitates the movement of nutrients through the soil and into plant roots. Water acts as a solvent, dissolving fertilizers so that their nutrients can be absorbed by plants. Without sufficient water, the nutrients may not be available in a form that plants can take up or may be locked away in the soil. When water is lacking, plants can experience drought stress, which further hampers their ability to absorb any available nutrients. This means that no matter how well-fertilized the soil may be, the plants cannot take full advantage of those nutrients without adequate moisture. The other factors listed can influence fertilizer uptake, but they do not play a direct role in the absorption process as water does. Soil temperature can affect microbial activity and chemical reactions in the soil, while soil texture can influence water retention and drainage. Sunlight exposure is vital for photosynthesis and overall plant health but does not directly impact the nutrient uptake process as significantly as water does.
