1913 – The Haber process, also called the Haber–Bosch process, made it possible to produce ammonia, and thereby fertilize, on an industrial scale. 1960 – First use with aerial photos in Earth sciences and agriculture. 1988 - First use of the Global Positioning System in agricultural applications, precision farming emerges.

Woolgathering is a practice similar to gleaning, but for wool. The practice was of collecting bits of wool that had gotten caught on bushes and fences or fallen on the ground as sheep passed by. The meandering perambulations of a woolgatherer give rise to the idiomatic sense of the word as meaning aimless wandering of the mind.
Agricultural waste, on the other hand, is a secondary raw material. They are residual (waste) streams from an existing industry that can serve as raw materials for new applications. Increasingly reusing materials as raw materials for the production process contributes to the EU goal of achieving a circular economy by 2050. [31]
A majority of food waste food is avoidable, with the rest being divided almost equally into foods which are unavoidable [clarification needed] (e.g. tea bags) and those that are unavoidable due to preference [clarification needed] (e.g. bread crusts) or cooking type (e.g. potato skins).
Crop residues are waste materials generated by agriculture. The two types are: Field residues are materials left in an agricultural field or orchard after the crop has been harvested. These residues include stalks and stubble (stems), leaves and seed pods. Good management of field residues can increase efficiency of irrigation and control of ...
According to a 2005 report by the USDA, more than 335–million tons of "dry matter" waste (the waste after water is removed) is produced annually on farms in the United States. [62] Animal feeding operations produce about 100 times more manure than the amount of human sewage sludge processed in US municipal waste water plants each year ...
What causes earthquakes? Earthquakes occur when the plates that make up the Earth's crust move around. These plates, called tectonic plates, can push against each other.
This migration event also saw the introduction of cultivated and domesticated food plants from Taiwan, Maritime Southeast Asia, and New Guinea into the Pacific Islands as canoe plants. Contact with Sri Lanka and Southern India by Austronesian sailors also led to an exchange of food plants which later became the origin of the valuable spice trade.
