Use

There are two ways to use the Ecology skills: Single point sample tests, and Ecology Survey Kits.

Single Point Tests

Degree	Test for	Using	Baseline	Notes
First	Heavy metal pollution	Tadpoles	0%	The more tadpoles die, the more heavy metals there are in the soil. If more tadpoles are used, the reading becomes more precise.
Second	Soil acidity	1 Cabbage Juice	7.0000	Standard pH scale. (Below 7 is acidic. Above 7 is alkaline.)
Third	Ground water level	1 Dried Flax	50%
Fourth	Phosphorus level	2 Buttermilk, 1 Dirt	25%
Fifth	Soot level	1 Papyrus Paper, 1 Cactus Sap	0%
Sixth - A	Nitrogen Level	1 Horned Hookworm, 2 Charcoal	25%
Sixth - B	Potassium Level	1 Sulphurous Water, 2 Charcoal	25%
Seventh	Salinity	1 Salt Water, 1 Copper Wire	0%

Ecology Survey Kits

This is a new feature that allows visualizing ecology over a large area, rather than a single point.

• Ecology Survey Kits are made on a chemistry lab (requires Ecology Level 6). Five kits are made at a time.

 Items needed for 5 kits:
  Cactus Sap 10
  Charcoal 10
  Sulfurous Water 2
  Dried Flax 10
  Copper wire 10
  Cabbage Juice 4
  Buttermilk 10
  Slat Water 4
  Boards 10
  Glass Jars 5

• Select the Ecology type you want and see a colored grid for 2 minutes.
• Colors on 500' x 500' grid represent levels.
• The results have been described as a "heat map" style.

Influence Ecology Layers

There are several way that ecology layers change, like mushrooms and certain buildings. Malard said that ecology got revamped in T10, and now the sweeper can also alter ecology layers when collecting items. From discord in #general it appears that:

• Ice blocks that melt on the ground increase groundwater
• Limestone will adjust pH level
• Charcoal moves the soot
• there are 4 items that will warp potassium
• Strange slag does influence ecology layers as well
• Growing Garlic seems to increase pH
• 40 saltpeter -> sweeper -> nitrogen 25.051 -> 25.510, needs more testing, after more testing was liking a confound
• 100 dung -> sweeper -> no change in nitrogen (1 test)
