TutorialOnFarming__part2 Farms grow crops, and <b>crops</b> can be used in various places but mainly to feed your people. But crops don’t grow for free, they consume <b>water</b> and <b>fertility</b>.
TutorialOnFarming__water Soil water level is replenished by rain and this is mostly sufficient for crops with low water demands (such as potatoes). However, rain is not a reliable water source and crops can yield less or even dry out and die when not having enough water.
TutorialOnFarming__water2 Having an external source of water is vital for reliable farming. This requires upgrading farms with irrigation systems (unlocked via research). <b>Irrigated Farms</b> only consume water when the soil gets dry so externally supplied water does not get wasted.

TutorialOnFertility__fertilizers1 Farmer’s biggest dream are fertilizers. They can increase the soil fertility beyond the natural equilibrium value, some even beyond 100%!
TutorialOnFertility__fertilizers3 Note that the higher your soil fertilization target is the lower the natural replenishment is. And once fertility climbs above 100%, the natural replenishment will turn negative which will require even more fertilizer to sustain it.

TutorialOnFertility__part1 Crop yield is based on <b>soil fertility</b>. If a farm has 50% soil fertility it will only have a 50% yield of products. Crops consume fertility as they grow but fertility is also naturally replenished over time (an empty farm would eventually reach 100% fertility).
TutorialOnFertility__part2 Note that soil fertility does not affect crop water consumption or growth duration. This means that crops growing on more fertile soil will not only yield more but also will be more water-efficient (greater yield for the same amount of water).
TutorialOnFertility__part3 Over time, crop fertility consumption and natural replenishment will stabilize at a value called <b>fertility equilibrium</b>. This value represents an <b>estimate of average soil fertility</b> based on the current growth schedule. The equilibrium exists because crop fertility consumption is constant but the natural replenishment speed increases as soil fertility gets lower.
TutorialOnFertility__rotation2 You can also <b>leave the field empty</b> with no crop planted. This gives the soil time to regenerate fertility naturally but it won’t eliminate the same-crop fertility penalty on its own.

TutorialOnHealth__name Health & pollution
TutorialOnHealth__part1 Your population has health. If health is positive, your population grows and provides you with extra unity. If health goes negative, your population starts to decline.
TutorialOnHealth__part2 You can increase your population's health by providing them with a variety of food, water, and healthcare.
TutorialOnHealth__part2Heading Positive effects
TutorialOnHealth__part3 Your population's health decreases if you emit pollution (air or water). Pollution on your island is global, so moving smoke stacks farther from your settlement won’t help. It is a good idea to keep your eye on how much pollution you emit.
