The Facts of Fertility Nutrients and their Functions Just like humans, plants require specific nutrients in specific amounts for healthy growth. Growth may also be stunted.
Plant tissues become sensitive to environmental stresses such as drought and heat.
At very high concentrations, roots can be damaged and leaves may brown. Nutrients are available at different amounts at different pHs. If pH is too high or low, some nutrients may not be available to the plant whiles others at the same time may become toxic. Microorganism in the soil eventually decompose, releasing nitrogen for plant use. Microorganisms work best when pH is neutral or slightly alkaline.
