Plant Nutrition and Soil: Essential Elements and Functions, Slides of Botany and Agronomy

Central University of HaryanaBotany and Agronomy

An overview of plant nutrition and soil, focusing on essential elements and their functions. It covers the importance of carbon, hydrogen, oxygen, and inorganic nutrients like nitrogen, phosphorus, sulfur, and iron for plant growth. The document also discusses the differences between micronutrients and macronutrients and their mobility within plants.

Plant Nutrition and Soil

  • Sun, Water, Nutrients necessary
  • CO2 and H20 into organic

compounds

  • Synthesize all required amino acids,

vitamins, using inorganic nutrients

from environment.

  • Evolution designed for efficient

uptake of raw material and

Plant Nutrition and Soils

Plant Nutrition- involves the uptake from the

envrionment of all the raw material required for

1. Essential biochemical processes (metabolism and

growth)

2. Distribution within the plant

More than 60 chemical elements identified

Not all essential (gold, silver, lead, mercury, arsenic,

uranium)

Phytoremediation- the removal of contaminants

The fungus Boletus parasiticus Forms Ectomycorrhizae on the Roots of a red pine (Pinus resinosa)

Increase uptake of water and Phophorus Also Protects against pathogenic Fungi and nematodes

Essential elements

  • Necessary for plant growth
  • In the absence plant displayed characteristic abnormalities of growth, or deficiency symptoms, reproduction
  • In 1880 established that at least 10 essential
  • Essential elements/minerals (inorganic nutrients)- Carbon, hydrogen, oxygen, potassium, calcium, magnesium, nitrogen , phosphorus, sulfur and iron
  • By the 1950’s added seven more, manganese, zinc, copper, chlorine, boron, molybdenum, and nickel

The essential elements can be divided

into Micronutrients and Macronutrients

  • Micronutrients- trace elements equal or less than

100 mg/kg

  • Macronutrients – require large amounts above 100

mg/kg

  • Nutrient sometimes greater in conc. Than soil thus

have to use energy

  • Certain plant species are chars. By specific

elements

Plants of the mustard family i.e. Wintercress use sulfur Synth. Mustard oil

Horsetail silicon into cell walls Making it indigestible for herbivoresDocsity.com

Nutrient Deficiency symptoms Depend on functions and mobility of essential elements

  • Chlorosis Fig. 29-3- loss or reduced development

of chlorophyll

  • Magnesium, essential for chlorophyll
    • Younger leaves vs. older leaves
    • Depends on phloem
    • Phosphorus, potassium and nitrogen are also phloem- mobile (appear in older first)
    • Iron and calcium are phloem immobile (appear in younger first)
    • Sulfur and zinc intermediate in mobility

Sorghum - Deficiency of iron a so called phloem immobile element results in symptoms of chlorosis in younger leaves
