Synthetic ammonia is a key component of artificial fertilizers.

Analogue Forestry: a method for restoring ecosystems, developed from local Sri Lankan home gardens by the Neo-Synthesis Research Centre (NSRC), that seeks to bring back what grew there originally.

It would be interesting to see a study on how many researchers feel separated from Ammonia: a gaseous compound of nitrogen and hydrogen (NH3) formed as a byproduct when bacteria decompose substances high in nitrogen.

Compost piles thick with manure often emit ammonia when hot.

Some key assumptions: Angiosperms: flowering plants that place their seeds in fruits.

The monocots have an embryo with a single cotyledon (seed leaf), three-part flowers, parallel leaf veins, and adventitious root growth.Angle of Repose: the steepest angle that slope, rock, or detritus material settles into without toppling.Builders of flood-prone roads and sliding hillside homes in California ignore the angle of repose so often that it could be renamed the angle of depose.Agricultural Pollution: pesticides, fertilizers, wastes, erosion dust, runoff from fields, and animal infections are a few of the varieties. (Most of the other half is industrial.)Air Pollution: sulfur oxides and particulates from industrial plants burning fossil fuels are the current worst forms of air pollution. Most air pollution derives in one form or another from the use of petroleum products, oil in particular. Albedo: the luminosity shining from a reflective surface. About 1/3 of the sun’s radiation is reflected back into space, with the remaining 42% warming the land and air and 23% moving water through the hydrologic cycle.
