Use

There are two ways to use the Ecology skills:

• Single point sample tests
• Ecology Survey Kits.

Ecology factors can be adjusted by hand-planting vegetables: https://atitd.wiki/tale10/Vegetable

Single Point Tests

Degree	Test for	Using	Baseline	Notes
0	Ground water level	1 Dried Flax ✓	50%
1	Heavy metal pollution	1+ 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.
2	Soil acidity	1 Cabbage Juice ✓	7.0000	Standard pH scale. (Below 7 is acidic. Above 7 is alkaline.)
3	Potassium Level	1 Sulphurous Water ✓, 2 Charcoal ✓	25%
3	Nitrogen Level	1 Golden Asp ✓, 2 Charcoal ✓	25%
4	Salinity	1 Salt Water ✓, 1 Copper Wire ✓	0%
5	Phosphorus level	1 Buttermilk ✓, 1 Dirt ✓	25%
6	Soot level	1 Papyrus Paper ✓, 1 Cactus Sap ✓	0%

Ecology Survey Kits

Ecology Survey Kits are made on a Chemistry Laboratory, requiring Ecology 4 (Skill). Five kits are made at a time.

• Select the Ecology type you want and see a colored grid for 2 minutes.
• Colors on 500' x 500' grid represent levels.

Cost

• 10 Charcoal ✓
• 10 Cactus Sap ✓
• 5 Sulphurous Water ✓
• 10 Dried Flax ✓
• 10 Copper Wire ✓
• 5 Cabbage Juice ✓
• 5 Buttermilk ✓
• 5 Salt Water ✓
• 10 Boards ✓
• 5 Glass Jars ✓

Affecting Ecology

Ecology effects cover a radius of roughly 60 co-ords from the point where the player is standing when the action is complete.

Material	Increases	Decreases	Required Action
Sulphurous Water	Ground Water +0.0153/jug	pH -0.002/jug	Empty Jugs
Salt Water	pH +0.002/jug, Ground Water +0.0153/jug		Empty Jugs
Jugs of Water	Ground Water +0.0153/jug	?	Empty Jugs

Each action has a small chance (maybe 5-10%) of having it's effect, calculated separately for each factor it might modify. When a stack of items is used, it will apply either the full stack or nothing - emptying 100 jugs of salt water at once could change the pH by +0.2, or the ground water by +1.53, or both or neither, but it wouldn't raise the pH by only 0.1.
