English: I retrieved the soil pH maps from . In GIMP 2.4.3 I used the "Select by Color Tool" (threshold 15.0) to create pH-specific maps. Note that the original maps do not indicate actual pH values in the pH scale. For soils with acidic pH, I included the colors indicated by the leftmost 14 bars in the pH scale, ranging from red to pink.

Then, using the initial soil pH and the aluminium content, the amount of lime needed to raise the pH to a desired level can be calculated. [68] Amendments other than agricultural lime that can be used to increase the pH of soil include wood ash, industrial calcium oxide , magnesium oxide, basic slag (calcium silicate), and oyster shells.

Level design or environment design, [7] is a discipline of game development involving the making of video game levels—locales, stages or missions. [ 8 ] [ 9 ] [ 10 ] This is commonly done using a level editor, a game development software designed for building levels; however, some games feature built-in level editing tools.
Soil map from "Geography of Ohio," 1923. A soil map is a geographical representation showing diversity of soil types or soil properties (soil pH, textures, organic matter, depths of horizons etc.) in the area of interest. [1] It is typically the result of a soil survey inventory, i.e. soil survey.
Example Bjerrum plot: Change in carbonate system of seawater from ocean acidification.. A Bjerrum plot (named after Niels Bjerrum), sometimes also known as a Sillén diagram (after Lars Gunnar Sillén), or a Hägg diagram (after Gunnar Hägg) [1] is a graph of the concentrations of the different species of a polyprotic acid in a solution, as a function of pH, [2] when the solution is at ...
Soil phase diagram showing soil composition. V is for volume, M is for mass. Subscripts s, w, and a stand for soil particles, water and air respectively. Subscripts v and t stand for voids and total respectively. Date: 9 June 2010, 11:05 (UTC) Source: Soilcomposition.png: Author: Derivative work: 5d7ygtr09h; Sjhan81
