44. How do plants take nitrogen and other nutrients like phosphorous, iron, magnesium etc.? What is the significance of nitrogen?(class 10)
Answers
Answer:
plants take nitrogen with the help of soil
Answer:
Plants, as well as all living things, need nutrients and minerals to thrive. These chemical elements are needed for growth, metabolic functioning, and completion of its life cycle.
Plants, as well as all living things, need nutrients and minerals to thrive. These chemical elements are needed for growth, metabolic functioning, and completion of its life cycle. Plants take in Carbon (C) and Oxygen (O2) in the air from their leaves. All other nutrients are found in the soil and are taken up for use in the roots. Macronutrients are consumed in large quantities: nitrogen (N), phosphorus (P), potassium (K), calcium (C), sulfur (S) and magnesium (Mg. Smaller amounts of micronutrients (or trace minerals) are needed: boron (B), chlorine (Cl), manganese (Mn), iron (Fe), zinc (Zn), copper (Cu), molybdenum (Mo), nickel (Ni).

Testing is available to see what nutrients are in the soil and if the PH is correct, which is necessary for the plant to absorb the nutrients. Nutrient deficiency requiring fertilizing and/or soil amending has many causes. Growing certain crops or plants might deplete the soil. In agriculture, crops are rotated from year to year with increasing soil fertility in mind. Some plants, like roses, are considered "heavy feeders" and need frequent fertilization. A problem that a plant exhibits can often be diagnosed as having a deficiency of a certain element. Iron chlorosis, a deficiency in iron, may be one reason why a plant's leaves turn yellow or brown between the veins.

Replenishing nutrients in the soil can be done by adding organic material such as compost, dehydrated manure, compost tea or fish emulsion. Traditionallly, most "all-in-one" chemical fertilizers have an "NPK" rating (Nitrogen-Phosphorus-Potassium) and can be purchased in liquid or granule form. In addition to other properties, Nitrogen helps plant foliage to grow strong. Phosphorous helps roots and flowers grow and develop. Potassium (Potash) is important for overall plant health. The plant needs will determine the ratio of each nutrient needed.
