Terrapsychology is a word coined by Craig Chalquist to describe deep, systematic, trans-empirical approaches to encountering the presence, soul, or "voice" of places and things: what the ancients knew as their resident genius loci or indwelling spirit. This perspective emerged from sustained ...
Pesticides, fertilizers, wastes, erosion dust, runoff from fields, and animal infections are a few of the varieties. According to the Environmental Protection Agency, half the water pollution in the U. S. Is agricultural. (Most of the other half is industrial. )
Industry:Biology
Declination, the angular distance north or south from the celestial equator (the imaginary sky curve projected upward from the Earth's equator), combines with right ascension (measurement along hour circles circling like meridians between the celestial poles) to plot sky objects in a grid similar to that of longitude and latitude. Because the Earth spins in space, right ascension is measured in time intervals rather than degrees of arc.
Industry:Biology
Secondary tropical or subtropical vegetation planted in forests in order to regenerate the soil between crops. In places like western Sudan, this traditional practice has been subverted by a Western emphasis on cash-producing monocrops in disregard of cultural or ecological consequences.
Industry:Biology
Average atmospheric conditions over a long time interval. Energy from the sun drives climate, which sets limits on a biome's plant life and therefore on the animals that live there. The Koppen-Geiger classification sorts major climates into five types: humid tropical, dry, humid warm, humid cold, and cold polar.
Industry:Biology
Using the same soil to grow different crops. Interrupts cycles of weeds, diseases, and insects; builds organic matter, improves soil structure. Useful rotations: nutrient-grabbing crops like corn, celery, and potatoes with those that need less, like garlic, mustard, or shallots; and shallow-rooting crops with deep ones. (Soil improvers: broad beans, lima beans, peanuts, peas, shell beans, snap beans, soybeans. )
Industry:Biology
A mixture of humus and particles weathered from rock. A cubic yard of soil will cover 300 square feet of ground to a depth of 1 inch. The major nutrients are nitrogen, phosphorus, and potassium. Bacteria and fungi produce humus. Half the volume of good soil is pore spaces. Microbial decomposers account for 60-80% of total soil metabolism; bacteria drive nitrification, sulfur oxication, and nitrogen fixation. Actinomycete microbes help form humus; they are the most numerous organisms after bacteria. Soil texture means the relative proportions of sand, silt, and clay. We live on 1/12 of the Earth’s surface but have discarded ¾ of its productive soil. Replacement of an inch of topsoil takes 500 years.
Industry:Biology
A hooved mammal that eats its food, regurgitates it (cud), and eats it again, a procedure made possible by a four-chambered stomach. Ruminants include cattle, bison, sheep, deer, goats, elk, giraffes, antelopes, and camels. Their specialized stomach evolved to extract the maximum of nutrients from low-quality food.

Un mammifero catturati che mangia il suo cibo, rigurgitò esso (cud) e si mangia ancora una volta, una procedura resa possibile da uno stomaco quattro-a temperatura ambiente. Ruminanti includono bestiami, bisonte, pecore, cervi, capre, alci, giraffe, antilopi e cammelli. Loro stomaco specializzato evoluti per estrarre il massimo delle sostanze nutrienti dal cibo di bassa qualità.
