Solid and liquid fertilizer consumption.

[bajecznie nawdychany]

Dear All,
I found a lot of information about the farming but I am still unable to get the mass of fertilizers required to have 200% fertility level every year (lets say per single big field).
I know that liquid fertilizer is easier to check but solid fertilizer is not applied each year.
Running an experiment for several years is tedious.
Do You have it noted anywhere and could share, please?

Thank You,

Did you set a higher minimum fertility? Farms may stop applying solid fertilizer if the field meets this threshold.

Dear Silent_Shadow.
Why this question? I just want to know how much bio waste I need to get enough fertilizer for fields.
I have like 45-50 big field. Is one full livestock hall/range enough to produce fertilizer for all those fields?

Guess I misunderstood what you were asking. I don't know the answer, but I do know if you enable cheats and press Ctrl while looking at a field's window, the amount of soild fertilizer present in the field will be displayed. That should make it pretty easy to determine how much solid fertilizer you need to get to 150% fertility, and from there figuring out how much liquid fertilizer is needed to get to 200% fertility.

Liquid fertilizer is 5 tons per Ha for 50% boost, which is best you ever get from it even if you end with less than 150%.

Solid fertilizer is 25 tons per Ha from increasing "actual nutrient level" from 0% to 100%, which is what the tractors will try to do unless interrupted. If interrupted (out of fertilizer, goes refuel, depot etc.) tractors won't return to field that has 150% fertility even if actual nutrient level is less than 100%

So for instance a freshly created pristine farm (70% fertility, 21% nutrient level) will take bit short of 5 tons/Ha of solid to go from 70% to 150% (nutrient level raises from 21% to 40%), but going from 21% nutrient to 100% nutrient takes just short of 20 tons/Ha of solid.

Tested by starting fresh game and experimenting with fertilizing bunch of small farms in February, then sowing and spraying them in March,

Does this take into account the fertility gain a field just gets over time?
I think it maxes out to 149% if you just leave it alone long enough.

Thank You Silent Shadow. I will check and ensure it is aligned with what NULL said. If so then this is all I need.

I really appreciate You inputs.

Best regards,

Good question. I first thought fallowing mechanics might not matter, but now that I have noticed that increasing fertility by equal amount of percentage points sometimes takes less or more fertilizer or that some other variable might be involved (see below) I'm not so sure.

Small correction actually. My previous test with the liquid fertilizer was an earlier one for whole 32 Ha farm setup on pristine fields. So fertility going from 7X% up to 12X%. This was indeed 5 tons/Ha. But now I repeated the test and found out that increasing fertility of a field that has 150% fertility and 100% nutrient level (i.e. fertilized to max extent with solid fertilizer) to 200% fertility and 100% nutrient level with liquid fertilizer only takes 3 tons/Ha of liquid.

So that 3 tons of liquid fertilizer is likely to be more accurate for normal farming setup.

Ultimately I ran a test on separate PC for 16 years. I aimed for 1 big field with full solid and liquid fertilizers available. Managed by single harvester, two tractors and 4 covered hulls.

Results are as follows:
1. Consumption of Liquid Fertilizer: 24T each year.
2. Consumption of Solid Fertilizer: around 92T each 4 years.
3. Production of Grain: around 600T each year.

On top of that simple test for full livestock hall/range produces 1064T of bio-waste per year, supplying around 46 big fields.
This should be enough to produce food, meat and clothes (including chemicals, excluding water purification) for just above 50k peoples.

We need some more grain anyway for chemicals in other industries like mentioned water purification.

Thanks for your efforts.
I will keep that in mind when I rig up my next farm.
