Question

why is phosphorus essential to plant farmer are facing less growth of roots and low growth of plant suggest the inchance productivity with relevant example​

Answer 1

Answer:

Phosphorus is one of 17 nutrients essen-

tial for plant growth. Its functions cannot

be performed by any other nutrient, and

an adequate supply of P is required for opti-

mum growth and reproduction. Phosphorus is

classified as a major nutrient, meaning that it

is frequently deficient for

crop production and is

required by crops in relative-

ly large amounts. The total P

concentration in agricultural

crops generally varies from

0.1 to 0.5 percent.

Uptake and Transport

of Phosphorus

Phosphorus enters the

plant through root hairs, root

tips, and the outermost layers

of root cells. Uptake is also

facilitated by mycorrhizal fungi that grow in

association with the roots of many crops.

Phosphorus is taken up mostly as the primary

orthophosphate ion (H2PO4

-

), but some is

also absorbed as secondary orthophosphate

(HPO4

=), this latter form increasing as the soil

pH increases.

Once inside the plant root, P may be

stored in the

root or trans-

ported to the

upper portions

of the plant. Through various chemical reac-

tions, it is incorporated into organic com-

pounds, including nucleic acids (DNA and

RNA), phosphoproteins, phospholipids, sugar

phosphates, enzymes, and energy-rich phos-

phate compounds...for example, adenosine

triphosphate (ATP). It is in these organic

forms as well as the inorganic phosphate ion

that P is moved throughout the plant, where it

is available for further reactions.
