Plants with fibrous root systems near the surface should be fertilized how?

Plants with fibrous root systems near the surface should be fertilized how?

• A. Sparingly
• B. Heavily
• C. Weekly
• D. Only with micronutrients

Answer: (A)

When roots are fibrous and stay near the soil surface, nutrients are most available in that upper layer. Piling on fertilizer in that zone can create a high salt concentration, which can burn tender shallow roots and increase losses from leaching or runoff after irrigation or rain. A sparing, gradual approach keeps nutrients available without stressing the roots, and it pairs well with slow-release products or split applications that match soil conditions and plant needs. Weekly feeding isn’t necessary and can still lead to salt buildup, while focusing only on micronutrients would neglect the plant’s need for macronutrients.
