Easy points: Is this a good paragraph for my biology class??The question was why is it important for soil to contain nitrogen, phosphorus, magnesium, and potassium. Soil is one of the main sources of nutrients needed by plants in order to grow. Nitrogen is used by plants for leaf growth and green color. Without nitrogen in the soil, the plant wouldn’t grow tall and produce enough food. Phosphorus is used by plants to help form new roots, make seeds, fruit and flowers. This is crucial because crops take up phosphorus only from the soil solution. Potassium helps plants form strong stems and fast growth. It also increases disease resistance. It triggers activation of enzymes and is essential for production of ATP. Magnesium is the central core of the chlorophyll molecule in the plant’s tissue. If Mg is deficient, the shortage of chlorophyll results in poor and stunted growth.
