Answer» nutrients in our food originally come from the soil. In order to create HEALTHY crops full of nutrients, farmers need to work with healthy soil. ... Farmers turn to fertilizers because these substances contain plant nutrients such as nitrogen, phosphorus, and potassium.Fertilisers provide mineral ions NEEDED for healthy growth in PLANTS. As plants grow, they absorb mineral ions from the WATER in the soil through their root HAIR cells . Over time, the concentration of these ions decreases, so farmers and gardeners add fertilisers to the soil. |
