Intensive Farming

Crops
1. Monoculture
  1. Farmers specialise in one type of crop
    1. Reduce Plant competition for food, light and etc.
    2. Control of undesirable organisms
  2. Enable disease to spread out quickly
Domesticated Livestocks
1. Any animals kept for use of profit
Farming Practice
1. Crop rotation to increase soil fertility
2. Ploughing aerates soil
3. Fertilisers
  1. Nitrogen for protein
  2. Phosphorous for ATP or DNA
4. Pests
  1. Pesticides
    1. Effective Pesticide shoud
      1. Specific
      2. biodegradable
      3. Bioaccumulate
      4. Cost effective
5. Biological control of pests
  1. Advantages
    1. Specific
      1. Intergrating Pest control system.
        Use biological agents.
        Use Pesticides as a last resort
    2. No bioaccumulation
    3. Doesn't develop resistance
    4. Once introduced, it reproduce itself
  2. Disadvantages
    1. Does not act as quickly as pesticides
    2. It may itself become a pest
Net Productivity= Gross Productivity - Respiratory Loss
1. Gross Productivity is the total amount of energy is fixed by photosynthesis
  1. To increase gross productivity fertiliser can be used
    1. To overcome the limitation of minerals
2. To reduce respiratory loss , movement is restricted so they are kept in confined cages.
  1. Predators are excluded
3. Kept in a warm environment to reduce heat loss
4. is the remainder of energy that is transfered to the next feeding level
5. Feeding can be controlled, so animals receive optimum amount
Minimise Input and Maximise Output
1. Using Hormones to increase growth
2. Selectively breed them to produce varities that are more efficient in conversion
  1. Reduces Genetic diversity
3. Use of antibiotics to prevent disease spread.
