  4. To prevent fertilizer runoff, use controlled-release fertilizers, apply fertilizers when rain is not expected, avoid over-fertilizing, use vegetative buffers along water bodies, employ conservation tillage methods, and maintain proper soil pH to reduce nutrient leaching.

  5. Plants acquire macro-nutrients, such as nitrogen, phosphorus, and potassium, from the soil through their roots via active or passive transport mechanisms. They obtain micro-nutrients, like iron and zinc, through similar processes. These nutrients dissolve in soil water and are absorbed by root hairsRead more

    Plants acquire macro-nutrients, such as nitrogen, phosphorus, and potassium, from the soil through their roots via active or passive transport mechanisms. They obtain micro-nutrients, like iron and zinc, through similar processes. These nutrients dissolve in soil water and are absorbed by root hairs, then transported through the plant’s vascular system to various tissues where they are utilized for growth and metabolism.
