Topic to be covered


  • Method to stay the mineral Requirements plant
  • Essential mineral element
  • Mechanism of Absorption of elements
  • Translocation of solutes
  • Soil as Reservation of Essential
  • Metabolism of nitrogen



What is plant nutrition?
Plant nutrition is the process of obtaining food and utilizing it for growth, repair, and metabolism.

Why does plant need minerals?

  1. It needs minerals for growth.
  2. It needs minerals for tissue repair.
  3. It needs minerals for Reproduction.
  4. It needs minerals for Metabolism.


Introduction Hydroponics
Julius von Sachs was the first to demonstrate the concept of Hydroponics.
Hydroponics is a technique of growing plants in a nutrition solution.

Essential and non-essential minerals

Essential mineral 

Essential mineral elements are necessary for a plant for growth and Reproduction.
N,P,S,K,Ca,Mg.

Non-essential Minerals elements

Non-essential minerals are not absolutely necessary for a plant to promote plant growth and it termed as beneficial elements.
Si,Co,Se,Na.

Essential non-minerals elements

  1. Elements necessary for a plant
  2. It has taken up in the form of water/air like C, H, O


Essential minerals elements characteristics

Necessary for growth and Reproduction and not replaceable by another element's direct role in metabolism.

Minerals Elements: Sub-classification

By on quantitative requirements by plants,
These are of 2 types

  1. Macronutrients
  2. Micronutrients


Macronutrients 
It is required by plants in a large amount.
It is two type
Primary nutrition: plant-primarily use them for growth and survival.
N, P, K
Secondary nutrients: These are found in soil in quite an abundance.
Ca, Mg, S.

Micronutrients
It is Require by plants in small amounts of trace elements
Fe, Mn, Cu, Mo, Zn, Cl, Ni.

The nutrition we will discuss them

N, P, K, Ca, Mg, S, Fe, Mn, Zn, Cu, B, Mo, Cl

 Nitrogen

Role

  1. Major constituent of proteins, vitamins, enzymes, hormone, and chlorophyll
  2. It helps in rapid growth
  3. It helps indirectly involved in metabolism.


Source

  1. It obtains from fertilizer
  2. It obtain from Air(legumes)


Deficiency

  1. After deficiency growth of the plant is stunted.
  2. Plant leaves make yellow.
  3. Excess nitrogen can delay flowering and fruiting.


Phosphorus

Role

  1. Major constituent of nucleic acid, some protein and cell membranes, and cell membranes.
  2. It helps in rapid root growth and maturation in plants.
  3. Directly involved in flower and fruit formation.


Source

  1. It obtains from fertilizer.
  2. It obtain from orthophosphate in rocks and soils.


 Deficiency

  1. With deficiency retarded root growth.
  2. The poor yield of fruits and flowers
  3. Retarded maturity of the plant.
  4. Purple/dark green stems and leaves.
