Fertilizers & Field Values
You should fertilize right after you plant as you can no longer fertilize after crops are can be harvested. Each fertilizer can have one or more effects on the field:
- Upkeep
- This reduces the amount of Humus needed to prepare a field as well as the amount of seeds needed to replant the field. The values after calculating for upkeep are base quantity * (Upkeep/100) This value has a bottom cap of 50%. Adding Wood Choppings to the field improves the upkeep by lowering the Upkeep value. Example: a field at 50% Upkeep will require 2 Humus to prepare and 25 Seeds of Grain to plant where as 100% upkeep requires 5 humus and 50 seeds.
- Plenty
- This value increases the yield of a field when harvested. Currently, planting a field provides a random amount plenty from 0% to a percentage equal to the planter's Stocks & Cultivars/100. The S&C bonus doesn't affect the fertilizer stacking penalty.
- Speed
- This value reduces the growth time of the field. Normally, a field advances one stage every 24 hours and the speed value reduces that time. For example, a field at 200% speed should gain a stage of growth every 12 hours.
- Influence
- This value boosts the amount of gain for the influence generated by the crop, this is important for getting higher tier crops. The full bonus is awarded regardless of the stage the crop is when harvested.

After a field is harvested, plenty, speed and influence are reset to 100%. After planting, each field loses 5% upkeep. For example, if you want to keep your field at 50%, then after you replant, you will need to lower the upkeep value from 55% to 50%.
- Hint: if you apply Wood Choppings as the fourth fertilizer, it will add 5% upkeep; doing it sooner just makes the other fertilizers less effective for no gain and doing it later will require 2 wood choppings.
Finally, the more fertilizers used on a field, the less effective next fertilizer becomes. Each fertilizer counts as one, so a Wood Chopping, a Coal, a Humus, and a Clay counts as four fertilizers, which would be the same reduction as using four Humus. The page for each fertilizer shows the amount of improvement for each field effect taking the number of previous applications of fertilizer into account.
- Note on cotton: It takes 10 clean cotton to produce a single cotton sheet, this can be achieve by a single field with approximately 200% plenty value.(click image below for larger version)
