Agricultural Practices and Land Use

A- Organic farming is the method of cultivation of crops through use of fertilizers of organic origin such as green manure, compost, bonemeal etc. It uses techniques such as crop rotation and companion plantation. Synthetic fertilizers and pesticides are strictly prohibited. 

To overcome the problems associated with the overuse of chemical fertilizers ,the farmers have now switched to organic farming . It is the process of use of natural methods like bio-fertilizer , manure , vermicompost & crop rotation etc.

Organic farming minimizes the use of synthetic fertilizers and pesticides, which reduces chemical runoff and preserves soil health. Other options like urban expansion and shifting agriculture often lead to deforestation and habitat destruction.

Organic foods or products are preferred because it has high nutritional value than conventional food . The reason for this is the absence of pesticides & fertilisers .  In the absence of these , the plants boost their production of phytochemicals that strengthen their resistance to bugs and weeds .

Organic farming uses only naturally produced inputs like compost and organic farming doesn't use pesticides and urea.

The farm land is ploughed and then not used for the cultivation of the crops for some time. This helps in the land to gain the fertility again and the method is known as field fallow. This provides the land some time to replenish its nutrients so that the next round of crops can grow properly.

The crop rotation is a pattern of growing a series of different types of crops in the same area in the sequential season. It is a method of replenishment of nutrients by the regular succession over the same field. It enhances the health of crops and minimizes the amount of pest. Thus, the correct answer is option D.

Inter-cropping optimizes the use of natural resources (sunlight, water, land), helps prevent soil erosion by providing better ground cover, and allows for separate harvesting and marketing of the different crops.

The green revolution refers to an unexpected and revolutionary spurt in the production of crops. A significant increase in agricultural productivity resulting from the introduction of a high yield variety of seeds, the use of pesticides, and improved management techniques.

Agricultural inputs are classified into two types.

1. Human inputs: Labour (workers), Machinery (tractors, combine harvesters, etc.), Buildings (barns, silos), seed to grow crops, animal feed, fertilisers and pesticides, calves, chicks, piglets, etc. (small animals brought to rear and later sell).

2. Natural inputs: Soil, precipitation, sun, alluvium, relief, drainage.

Crop rotation involves growing different types of crops in succession, which helps maintain soil nutrients and prevents the depletion of specific minerals.

All the mentioned methods were adopted under green revolution. It was a period when agriculture increased its yield due to improved agriculture techniques.

Answer is option C i.e. "Agriculture depends on non-renewable resource"
Green Revolution technologies and concepts requires non-renewable resources to generate results. People must use agricultural machinery to maintain their fields to achieve higher yields. Agricultural production by green revolution is highly dependent on non-renewable resources. Agricultural machinery and transport, as well as the production of pesticides and nitrates all depend on fossil fuel.
