What methods have been introduced in farming to increase food supply?

Posted by admin

hey can someone pelase help me. i have science homework I have to find information on farming methods that have been introduced to increase food supply. If anyone knows any or has any links it’d be appreciated. Thanks :)

As far as dairy farming:

1. More sophisticated nutritional understanding and better diet rationing to improve production.

2. Although unpopular, artificial hormone injections.

3. Artificial insemination techniques that allow cows to be bred sooner after calving and therefore give birth more often, and therefore produce more milk. Artificial insemination also allows for better selective breeding to increase the species’ ability to produce more milk through genetics.

    firstly you must do trip irrigation. proper fertilizer apply in correct timing, anti spray apply in correct timing,

    Look up hybrid seed production, chemical weed control and modern farm machinery. I would say those were the biggest improvements.

    For food crops:

    The crop yield in the United States is currently high, so only small to modest improvement can occur. The most significant market for methods to improve crop yield are in developing countries.

    The primary method used to increase crop yield deals with reducing crop loss from insects and weeds. Secondly, fertilizers are used to increase the nutrient profile of nutrient-poor soils. Thirdly, crop rotation is used to reduce the effects of planting the same crop on the same plot of land year in and year out. Next, improved irrigation for areas in which rainfall, water supply or drainage is poor can prevent crop loss. Lastly, genetically modified crops have been generated to address crop loss due to insects and weeds. In poor countries, planting the genetically modified plants is sometimes cheaper than having to apply pesticides, and has a less immediate impact on the environment (nonspecific toxicity to other organism). Genetically modified crops that are herbicide resistant allow farmers to apply sufficient herbicide to kill weeds without damaging their crop. However, this is not as attractive, since herbicides are expensive and may require multiple application during one season.

    1. Pesticides

    2. Fertilizers

    3. Crop Rotation

    4. Improved Irrigation and Drainage

    5. Genetically Modified Plants (incorporating genes that make plants either produce molecules that kill insects or are resist to herbicides.)

    See the links below this is some of my own work on the subject.
