THE FULL DEFINITION OF PLANT NUTRIENT

 WHAT'S PLANT NUTRIENT ?

Plant nutrient are mineral element present to the soil which survive as food to the plant for growth and productivity. A soil is fertile if it contains adequate nutrient element both in forms and amount of the soil therefore the capacity of soil to supply mineral nutrient element for crops in the production in the required quality and form. 

 The productivity of the soil is a combination of the soil fertility and other environmental factors, some soil may be fertile but not productive. 

This is done due to the imbalance of all other factors in the environment that determine high crop production these factors must be in favourable balance before high crop production can be achieved. Environment such as adequate rainfall, temperature, past and disease problem e.t.c.

  Seventeen are know to the essential to the growth and development of plant these can be grouped into two depending on the quatity required by plant (Viz macro and micro element).

   The macro element or nutrients

Macro element are those mineral element in the soil which are required by crops plant in large quantities of successful growth and development. 

Exp are carbon, oxygen, hydrogen, nitrogen, phosphorus, potassium, calcium, magnesiums and sulphur.

   Macro element from absorbed by plant

1) carbon (c) / CO2

2) oxygen (o) / co²3 so4 co²2

3) nitrogen (⁰N)/ No3 Now, NI A±4

4) hydrogen (H) /H20, H+

5) phosphorus (p)/ (hp-o²H2)po4

6) potassium (k) / k+

7) calcium (c) / ca²+

8) magnesium (mg) / mg²+

9) sulphur (s) / so4² - so²3

Deficiency of any of these lead's to poor growth, low yield and appearance of various deficiency symptoms.

      The micro nutrient or element 

Micro nutrient are those element required in small quantity but are very essential for the optimum growth of plant deficiency of any of those mineral lead to poor growth and low yield of plant example are iron, cupper, molybdenum, chlorine, manganese, zinc, boron and cobalt.

Micro element from obsorbed by plant

1) iron (Fe) / fe² fs+

2) cupper (cu) / cu²+ cu+

3) molybdenum/ mo o4

4) chlorine (cl-) / cl-

5) zinc (zn) / zn²+

6) manganese (MN)+/ mn²+ mn⁴+

7) boron (b) / be o7²-h² bo3 hbo²3- bo²3

8) cobalt (co) / co²+.
