We eat food in order to live. Plants have no teeth or mouth. They too take in food. They need food to live longer. Plants’ food is called manure.
         Scientists say that plants take in simple manure. They then make the food they take to change into complex food.
         Manure can help plants grow strong. They must be taken along with other trace elements. These trace elements can only be found in the soil.
         To grow well and produce flowers, fruits and seeds, plants have to take in manure and trace elements in the soil.
         Nitrogen, phosphorus and potassium are different kinds of trace elements. By just adding manure to the soil, the plants won’t grow. We need to know well about gardening before we add manure to plants. Wrong manure can kill plants too.
