Plants obtain nutrients from three sources: air, water, and soil. Air provides carbon and oxygen, water provides hydrogen, and soil provides 13 essential nutrients including nitrogen, phosphorus, potassium, calcium, and magnesium. Of the 13 nutrients from soil, nitrogen, phosphorus, potassium, calcium, and magnesium are required in large quantities and are called macronutrients, while the remaining 7 including iron and zinc are needed in small amounts and are called micronutrients.

2. Food resources
For their existence, all living organisms
essential require food. Food supply
proteins,carbohydrates,lipids,vitamins and
minerals which are essential the living organism
for the growth and development of living
organisms. It also protects the body and
provides energy for doing all life functions.

3. Nutrient Management; Nutrients are the food of the plants. The food required by plants is
provided by certain mineral elements, which are known as plant nutrients. Plant absorbs a large
number of elements from the soil.
Sources of essential plant nutrients
The plants get nutrients from three different sources. These sources are air, water and water and
soil. The nutrients available from these three sources to the plants are shown in the following
table.
out of 13 nutrients obtained from the soil nitrogen, phosphorous potassium,
calcium,magnesium,sulphur are required by plants relatively in large quantities, hence they are
called major of macronutrients. The remaining 7 are iron, boron, manganese, zinc, copper;
molybdenum and chlorine used by plants in very small quantities are called minor or
micronutrients.
Air Water Soil
Carbon
oxygen
Hydrogen Nitrogen,Phosphorous,
Pottasium,calcium,magn
esium,zinc chlorine etc.

4. Irrigation System: Keeping in mind the scarcity of water and varied
climate of our country, several irrigation systems are adopted to
supply required water; to agriculture lands. These systems are as
under:
Canal system: Rotation system provides adequate irrigation to all the
fields when the water supply is short.
Wells, dug wells, Tube wells, River lift system, Tanks are the irrigation
system
Weed control:
Weeds are unwanted plants in cultivated fields. Weeds tend to
compete with the crops for food, space and light. In comparison of
cultivated crops, the seeds of weeds germinate easily and their seeds
grow faster. In facts weeds take up all the nutrients and reduce the
growth of crop in various ways. Therefore, removal of weeds from
cultivated field in early stage of crop is essential for a food harvest.

5. Animal Husbandry:
The branch of agriculture that deals with feeding, caring and breeding of
domestic animals called animal husbandry.
Animal based farming includes cattle, goatsheep, poultry and fish farming.
Breeds of Buffaloes: There are 10 breeds of buffaloes in our country. The
following are the three important breeds that yield more milk:
Murrah: It is the native of Haryana and Punjab. The average yield of milk is
1800 to 2000litres, during its lactation period.
Mehsana: This buffalo is native of Mehsana and Vadodara districts of Gujarat. It
gives 1200 to 2500 litres milk during lactation period.
Surti: It is native of Kheda and Vadodara districts of Gujarat. It gives 1600 to
1800 milk during lactation period.
Fish production: Fish is a valuable and important resource of food, rich in
proteins. There are two types of obtaining fish, one is from natural resources,
which is captured fishing and other is by fish farming, called culture fishing.

6. India has a vast scope of marine fishery. Our marine
fishery resources include 7500 km coast line and
extensive deep sea. The most preferred Indian sea fishes
or table fishes are : Pomphrets, Tuna, Bombay duck. Eel,
etc.Fishes like Bombay duck and pomphrets are available
in large quanitty on the sea coast of Saurashtra and Kutch
of Gujarat .
Bee-Keeping : The practice of bee keeping is called
apiculture. IT is done to get honey and bee’s keeping
needs low investments, farmers use it is an additional
income generative activity.

7. Manure:
Manures are organic materials added to the soil to increase the production of crops. They
are biological in origin. They contain large quantities of organic matter and also supply
small quantities of nutrients to the soil.
Fertilizers:
Fertilizers are manufactured artificially in the industrial units by the use of chemicals and
are used for the commercial purpose. They contain much higher amount of nutrients.
They contain much higher amount of nutrients, hence they are used in very small
quantities. Fertilizers supply nitrogen,phosphorous and pottassium and are used for good
vegetative growth.
