Key Features of Class 9 Science Chapter 12

  • Crop nutrients are required in several forms. Some nutrients are needed in large amounts and are called macro-nutrients, while others are needed in small amounts and are called micronutrients. 

  • The main sources of nutrients for crops are manure and fertilizers.

  • Organic farming is a type of farming that minimizes or eliminates the use of chemicals such as fertilisers, pesticides, etc. and uses a maximum amount of organic manure, recycled farm waste, and bio-agents.

  • Mixed farming is a form of farming that includes crop production, livestock raising, etc.

  • Intercropping is the growing of 2 or more crops on the same piece of land, in specific row patterns.

  • Crop rotation is the growing of a variety of crops on a pre-planned succession.

  • Animal husbandry refers to the proper care and management of farm animals, such as shelter, feeding, breeding, disease control, etc.

  • Poultry farming refers to the raising of domestic fowls for eggs and broilers for meat production.

  • Cross breeding between Indian and exotic breeds is used to improve the variety of poultry.

  • Fish can be obtained from both marine and inland resources.

  • To increase the production of fish, fish can be cultured in both marine and inland ecosystems.

  • Marine fish can be caught by fishing nets using echo-sounders and satellites.

  • A composite fish culture system is often used for fish farming.

  • Bee-keeping refers to the gathering of honey and wax.
