Agronomy is the science and technology of producing and using plants by agriculture for food, fuel, fiber, chemicals, recreation, or land conservation. Agronomy has come to include research of plant genetics, plant physiology, meteorology, and soil science. It is the application of a combination of sciences such as biology, chemistry, economics ...
Sustainable agriculture mean the ability to permanently and continuously "feed its constituent populations". [77] There are a lot of opportunities that can increase farmers' profits, improve communities, and continue sustainable practices. For example, in Uganda, Genetically Modified Organisms were originally illegal.
Agricultural pollution refers to biotic and abiotic byproducts of farming practices that result in contamination or degradation of the environment and surrounding ecosystems, and/or cause injury to humans and their economic interests. The pollution may come from a variety of sources, ranging from point source water pollution (from a single ...
Sugarcane or sugar cane is a species of tall, perennial grass (in the genus Saccharum, tribe Andropogoneae) that is used for sugar production. The plants are 2–6 m (6–20 ft) tall with stout, jointed, fibrous stalks that are rich in sucrose, [1] which accumulates in the stalk internodes. Sugarcanes belong to the grass family, Poaceae, an ...

Effects on plants caused by increasing atmospheric CO 2 and methane. Elevated atmospheric carbon dioxide affects plants in a variety of ways. Elevated CO 2 increases crop yields and growth through an increase in photosynthetic rate, and it also decreases water loss as a result of stomatal closing.
