Explanation:
Detailed explanation-1: -Phosphorus is present in plant and animal cells and is vital to all plants for harvesting the sun’s energy and converting it into growth and reproduction.
Detailed explanation-2: -Phosphorus deficiency tends to inhibit or prevent shoot growth. Leaves turn dark, dull, blue-green, and may become pale in severe deficiency. Reddish, reddish-violet, or violet color develops from increased anthocyanin synthesis. Symptoms appear first on older parts of the plant.
Detailed explanation-3: -Adding phosphorus to soil low in available phosphorus promotes root growth and winter hardiness, stimulates tillering, and often hastens maturity.
