When crops advance from one growth stage to the next, they consume nutrients from the farmland on which they are planted. The required nutrient, K, P, or N, is the nutrient that will be consumed, reducing the concentration of that nutrient in the farmland. The amount of the nutrient required per growth stage is determined by dividing the Nutrient Consumption by the number of growth stages. | When crops advance from one growth stage to the next, they consume nutrients from the farmland on which they are planted.

Nutrients in farmland slowly replenish over time and return to the maximum level per soil type, for instance medium fertility will only regain nutrients to original levels. The rate of nutrient replenishment is slower if a crop is growing on it and faster when left fallow - meaning no crop growing. The nutrition type used by the currently growing crop will regenerate even slower then the two not actively used, and effectively wont replenish at all, as the currently growing crop reduces it with every growth tick. If the crop on the farmland is ripe, none of the nutrients will replenish.<br> | Nutrients in farmland slowly replenish over time and return to the maximum level per soil type, for instance medium fertility will only regain nutrients to original levels.

==== Crop rotation ==== | |||
Crop rotation is the practice of growing a series of different types of crops in the same area over time and has been used since ancient times to maximize crop production. Nitrogen (N), phosphate (P) and potassium (K) dependent crops can be rotated on the same growing area. For example, after harvesting a nitrogen dependent crop such as turnips, the soil will have a lower level of nitrogen but high levels of the two other nutrients. Therefore a phosphate or potassium dependent crop can be planted on the same soil. | |||
A common crop rotation strategy is to divide the fertile area into four sections, one each for N, P or K dependent crops and one left fallow (without any crops growing). After the first crops are harvested, the new crops are rotated to the next area e.g N dependent crops to the area where P dependent crops were harvested. Because nutrients replenish best in fallow soil, one area is kept unplanted during each rotation. This is particularly useful if the player does not have access to fertilizer yet. | |||

Fertilizer such as [[saltpeter]], [[potash]] and [[bonemeal]] can be applied to the soil to replenish nutriments depleted by the growth of crops without waiting for the slow natural replenishment in fallow soil (no crops planted) or the need for crop rotation. | |||
For example, the important crop flax removes potassium from the soil as it grows. Adding potash or saltpeter to the depleted soil after harvest will replenish potassium levels and allow replanting of flax on the same soil without waiting for natural replenishment and without the need for crop rotation. The type and amount of nutrient required for each crop is shown in the table of available crops in the next section. Having sufficient nutrients for each crop allows for the optimal growth rate if temperature and light requirements are also met. | |||
Using fertilizer is the only time a soil type can exceed the maximum nutrient level of the soil type. | |||
Note that saltpeter can't be detected by a [[prospecting pick]] (propick) and must be found while exploring caves. | |||
