One of the most effective ways to supplement the nutrients in the soil is through the use of manures or fertilizers. Manures, which are the end-products of digestion produced by livestock, are a rich source of nutrients for plants, containing nitrogen, phosphorus, and potassium, as well as a range of other essential elements. By incorporating manures into the soil, farmers and gardeners can provide the nutrients that plants need to grow and thrive.
However, manures can also contain pathogens and other contaminants that can harm plants, so it’s important to use them correctly. Manures should be decomposed and aged in the soil or in a compost pile to allow the beneficial bacteria and fungi to break them down and make the nutrients available to plants. When used correctly, manures can provide a low-cost and environmentally friendly way to add nutrients to the soil.
