Detailed explanation-1: -Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur.
Detailed explanation-2: -Diffusion operates by these highly concentrated ions moving as far away from one another as possible, and becoming exposed and available to the plant roots. Phosphate, potassium and zinc are the main nutrient ions moving as a result of diffusion.
Detailed explanation-3: -The majority of nutrient input to agriculture comes from commercial mineral fertilizers. Organic manures are considered to play a significant but lesser role in nutrient contribution, leaving aside their beneficial effects on soil physico-chemical and biological properties.
