The cracking of joints, especially knuckles, was long believed to lead to arthritis and other joint problems. However, this has been debunked . The cracking mechanism and the resulting sound is caused by dissolved gas (nitrogen gas) cavitation bubbles suddenly collapsing inside the joints. This happens when the joint cavity is stretched beyond ...

Researchers said on Wednesday they have settled the issue of what occurs inside knuckles to trigger the familiar popping sound. Snap, crackle, pop: study reveals secret behind knuckle-cracking ...
Some bacteria can convert N 2 into ammonia by the process termed nitrogen fixation; these bacteria are either free-living or form symbiotic associations with plants or other organisms (e.g., termites, protozoa), while other bacteria bring about transformations of ammonia to nitrate, and of nitrate to N 2 or other nitrogen gases.
Soil organisms use any nitrogen available to break down carbon sources, making nitrogen unavailable to plants. [1] This is known as "robbing" the soil of nitrogen. All vegetables apart from nitrogen fixing legumes are prone to this disorder. Nitrogen deficiency can be prevented by using grass mowings as a mulch or foliar feeding with manure.
The nutrient content of a plant can be assessed by testing a sample of tissue from that plant. These tests are important in agriculture since fertilizer application can be fine-tuned if the plants nutrient status is known. Nitrogen most commonly limits plant growth and is the most managed nutrient.
Anatomically, it is said that the knuckles consist of the metacarpophalangeal [1] (MCP) and interphalangeal (IP) joints of the finger. The knuckles at the base of the fingers may be referred to as the 1st [1] or major knuckles while the knuckles at the midfinger are known as the 2nd [2] and 3rd, or minor, knuckles.
