Amount of stored water ready for irrigation. Farm will automatically start irrigation when soil water level is low. Irrigation will be always off during rain.
Fertilizers can be used to artificially increase soil fertility above its natural equilibrium. Some fertilizers can even raise soil fertility above 100%. Use the green slider to set the desired fertilization target. Fertilizer has to be delivered via pipes. When different types of fertilizers are delivered, their properties will be proportionally mixed.
Amount of extra fertility needed on average (for the current crop rotation) in order to reach target fertility level. This extra fertility needs to be supplied with fertilizer.
Monthly rate at which the soil fertility replenishes naturally (without fertilizer).The less fertile soil, the higher replenish rate. When soil fertility is above 100%, natural replenishment will be negative and fertility will slowly decrease.
Fertility equilibrium is a value to which soil fertility will converge naturally for the current crop schedule. At the equilibrium, crop fertility consumption is equal to the natural replenishment rate. If there are multiple crops setup in a rotation, this value is only approximate since each crop may have different equilibrium value. Note that equilibrium does not take fertilizer into account.
