Detailed explanation-1: -The three processes that are responsible for nutrients from the soil reach the plant root system: diffusion, mass transport, and root interception.
Detailed explanation-2: -Process of Nutrients Absorption The roots can also absorb nutrients from the air and water. The process of roots taking in nutrients is called absorption. Once the roots have absorbed the nutrients, they transport them to the stems. The stems typically transport the nutrient’s to the leaves.
Detailed explanation-3: -Mineral nutrients come from the soil. These nutrients are absorbed by the plants roots when uptaking water. Mineral nutrients are broken up into macronutrients and micronutrients. The most important primary macronutrients for plants are nitrogen (N), phosphorus (P), and potassium (K).
Detailed explanation-4: -Plants take up essential elements from the soil through their roots and from the air through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.
