Intensive and extensive farming

hi guys,
for all those who got help from my presentation.. thank you for watching.. i will make new presentations on new topics every friday..

1. Made by: Anam Khan Class: VIII-A Intensive and extensive farming

2. Intensive farming  or  intensive agriculture  is an  agricultural  production system characterized by a low  fallow  ratio and the high use of inputs such as  capital ,  labor , or heavy use of pesticides  and chemical  fertilizers  relative to land area. All about INTENSIVE farming..

3. This is in contrast to many sorts of  traditional agriculture  in which the inputs per unit land are lower. With intensification, energy use typically goes up, initially provided by humans, then supplemented with animals, and supplemented or replaced with machines. C on..

4. Intensive animal farming practices  can involve very large numbers of animals raised on limited land which require large amounts of food, water and medical inputs (required to keep the animals healthy in cramped conditions ).  Very large or confined indoor intensive livestock operations (particularly descriptive of common US farming practices) are often referred to as factory farming  and are criticized by opponents for the low level of animal welfare standards  and associated pollution and health issues. T i..

5. Modern-day forms of  intensive crop based agriculture  involve the use of mechanical ploughing , plastic mulches, chemical  fertilizers , plant growth regulators or  pesticides . It is associated with the increasing use of  agricultural mechanization , which has enabled a substantial increase in production, yet has also dramatically increased environmental pollution by increasing erosion and poisoning water with agricultural chemicals. N u..

6. The methods of modern intensive farming include  innovation  in agricultural machinery and farming methods,  genetic technology , techniques for achieving  economies of scale  in production, the creation of new markets for consumption, the application of  patent  protection to genetic information, and  global trade . a..

7. These methods are widespread in  developed nations and increasingly prevalent worldwide. Most the  meat ,  dairy ,  eggs ,  fruits , and  vegetables available in  supermarkets  are produced using these methods of industrial agriculture. T ion..

9. Extensive farming  or  extensive agriculture  (as opposed to  intensive farming ) is an agricultural production system that uses small inputs of  labor , fertilizers, and  capital , relative to the land area being farmed . A ll about EXTENSIVE farming..

10. Extensive farming most commonly refers to sheep and cattle farming in areas with low agricultural productivity, but can also refer to large-scale growing of  wheat , barley  and other grain crops in areas like the  Murray-Darling Basin .  C ontin..

11. Here, owing to the extreme age and poverty of the soils, yields per hectare are very low, but the flat terrain and very large farm sizes mean yields per unit of labor are high . Nomadic herding  is an extreme example of extensive farming, where herders move their animals to use feed from occasional rainfalls. uation …
