Notation: let the symbol Def. indicate that a definition is following.

Notation: let the symbols between [ and ] be replacement for that portion of a quoted text.

Notation: let the symbol ... indicate unneeded portion of a quoted text.

Sometimes these are combined as [...] to indicate that text has been replaced by ....


To help with definitions, their meanings and intents, there is the learning resource theory of definition.

Def. evidence that demonstrates that a concept is possible is called proof of concept.

The proof-of-concept structure consists of

  1. background,
  2. procedures,
  3. findings, and
  4. interpretation.[1]

The findings demonstrate a statistically systematic change from the status quo or the control group.

Control group[edit]


Def. "[t]he science of utilizing plants, animals and soils for food, fuel, feed, and fiber and more"[2] is called agronomy.


Def. the science or practice of planting, managing, and caring for forests is called forestry.


Def. the "art or science of cultivating gardens"[3] is called horticulture.


Def. "the process or action of cultivating of the soil particularly in"[4] an "outdoor area containing one or more types of plants"[5] is called gardening.


Def. "[t]he art or science of cultivating the ground, including the harvesting of crops, and the rearing and management of livestock; tillage; husbandry; farming"[6] is called agriculture.


"In soil, estimates are that 80 to 99% of the microorganisms remain unidentified (1)."[7]

"The soil at the Arlington site is a Plano silt-loam. The 20-cm-deep A horizon is a silt-loam and contains 4.4% organic matter. The loess mantel is >1.25 m deep. Four 2.5-cm-diameter soil cores were taken from the top 10 cm of a clover-grass pasture at the Arlington Agricultural Research Station. The soil samples were immediately placed on dry ice, mixed, and then stored at -70°C prior to DNA extraction. Soil analysis was done by the Soil Testing Laboratory of the University of Wisconsin—Madison as described by Schulte et al. (40). The soil sample contained 13% sand, 70% silt, 17% clay, 4.4% organic matter, 0.3% total N, 400 ppm of K+, and 98 ppm of P. The soil pH was 6.5. The site is well drained, with groundwater more than 25 m below the surface. Two-thirds of the 79-cm annual rainfall occurs from April to October. The site has an average of 165 frost-free days."[7]
