Agricultural Practices and Land Use

Deep litter (floor-based with bedding material) and cage systems (wire cages) are two primary housing methods in poultry farming. They are not associated with dairy, pigs, quali (likely a typo for quail), or sheep rearing. These systems are specifically designed for broiler or layer chicken production.

All are soil conservation methods.

Derwent Whittlesey delineated the world's agricultural regions in 1936, creating a comprehensive classification system based on agricultural practices and land use patterns. This work became foundational in agricultural geography.

Greenhouses are enclosed structures that trap solar heat, maintaining warm temperatures for tropical plants during cold winters. Nurseries are for raising seedlings, gardens are outdoor planting areas, and orchards are for growing fruit trees - none provide the controlled warm environment that greenhouses do.

Yes, because of broader tyres, a tractor exerts less pressure over the ground as pressure decreases with increase in surface area or contact, and hence easily runs over the muddy field.

Cover crops are interested in sustainable agriculture as many of them improve the sustainability of agroecosystem attributes and may also indirectly improve qualities of neighboring natural ecosystems.

In domestic gardens, methods of weed control include covering an area of ground with a material that creates a hostile environment for weed growth, known as a weed mat. Several layers of wet newspaper prevent light from reaching the plants beneath, which kills them.

Biodegradable waste can be recycled by the method of composting. It is a natural process that recycles the nutrients in the waste to yield manure. Manure obtained is very rich in nutrients and is an excellent medium for growing plants.

Organic farming emphasizes natural methods over synthetic chemicals. Using biological predators like ladybugs to control pests is a core organic technique. Growth regulators, inorganic fertilizers, and malathion (a pesticide) are all synthetic/chemical inputs prohibited in organic farming.

Good plantation with adequate vegetation cover is the most effective soil conservation method because plant roots bind soil particles and prevent erosion. Low rainfall, low temperature, and restricted human activity are not practical or primary conservation methods - vegetation is key.

Rainfed farming is indeed complex, diverse, and risk-prone (making statements 1 and 2 true). However, statement 3 is false - rainfed farming is characterized by LOW levels of productivity and LOW input uses, not high productivity.

Third statement is incorrect.1, 2 and 4 statements are correct. 

Lay farming is a type of agrostological method.

Protection of soil erosion by preparation of field with alternate furrows and ridges is called contour farming.

 Cynodon doctylon is used in agrostological method of soil conservation.
