Agricultural Practices and Land Use

Agricultural practices are the processes adopted in the field such as preparing the soil, adding nutrients for the growth of crops and cutting down the crop i.e. harvesting, whereas selling grains in a market does not involve any field process and is thus not an agricultural practice. 

Agriculture is the science, art, and practice of cultivating plants and livestock for food, fiber, and other products used to sustain human life.

Rollers are used to crush clods and compact the soil. Since none of the specific conditions listed (wet, clods, friable) are the exclusive or only condition for use, 'None of the above' is the most technically correct answer.

Mole drainage is a method of land drainage used in heavy clay soils, and it is widely practiced in New Zealand to improve pasture productivity.

A seed-drill is a specialized agricultural implement designed to perform multiple tasks in one pass. It creates furrows, drops seeds at a consistent depth and spacing, and covers them with soil to ensure proper germination.

Slash and burn is a forestry technique, which involves cutting down trees and shrubs, on a large swath of land, allowing them to dry, and then setting a fire. It is a rapid and effective method for clearing a chunk of land, typically with the intention of converting it, for agricultural use. It does not characterize green revolution.

Dr. M.S. Swaminathan, known as the father of the Green Revolution in India, coined the term 'Evergreen Revolution' to describe the need for sustainable and continuous growth in food production.

The Murrah breed of buffalo is world-famous for its high milk production and is native to the Haryana region.

A solid substance is not soluble and is heavier than the liquid, it will settle down at the bottom and the process is known as sedimentation. This process is helpful in removing impurities e.g. dust particles from rice as rice being heavier settle down and dust being lighter stays at the surface and can be easily removed. 

 Red Sindhi is an indigenous breed of cattle.

Synthetic fertilizers are chemical which are prepared in factories. They are rich in specific nutrients like nitrogen, potassium and phosphorus. They are not used in organic farming.

 Agricultural practices are practised in a stepwise manner to optimize the growth of crops. First, the soil is prepared by loosening and turning to sow the seeds and then nutrients are added for good growth of seeds. Then appropriate amount of water is supplied by irrigation after which the unwanted plants are removed. This process is known as weeding. 

Farmer prepares the soil by using different implements. Earthworms during their activity in the soil help in loosening and turning the soil to optimize its efficiency and are thus known as farmer's friend.
