How fertility spreads

[Furin]

More useless info for you all. Did a little test on a barren mountain top, this is the result. As you can see fertility is generated in columns, spreading from the side where the dropoff point is. (probably important, I changed the soil mixture to beans at the start).

A couple of years later this field is stuck at 96% fertility. As you can see the last column refuses to go full green, even with multiple aplication of poop over some years and the shown crops. It might be that the distance to the origin of the fertility spread is too far.

Should be easy enough to test, I destroy the field and move it exactly one column to the left. Now I make the same rotation and poopilize it every year, just like the other one. Field starts at 84% fertility this time. I should probably reload the save and see what an expansion does, but I really don't wanna, just doing this project on the side while my villagers mine out a mountain...

So a couple of years later, the one column that refused to go up is now fully green, while the column next to it is still barren. I'll leave it like this for a while longer, just to see what happens.

I pumped poo into this field for 20 years, the last column never changed color, the fertility never went over 92%.

Then I turned the field 180 degrees, observe what hapened in just 2 years. See the yellowish tint? Fertility is going up. Spreading from dropoff point confirmed.

In conclusion, if you have a part of a field that doesn't want to get green, no matter how much dung you throw at it, turn the sucker around.

good info!

Super useful, I'm still trying to figure out how exactly it works. Kind of ironic you have a mountain top base as well, I havent seen anyone else do this really other than us two.

So you answered my first question, essentially fertility is the base it will start at, but you can take any land and make it fertile, based off what you showed. I assumed I couldnt build farms at the top of my base, and was thinking that fertility decreased at higher elevations and increased at lower.. but probably not.

Now what I'm curious about is grazing, and how if at all, it relates to fertility.

I havent noticed this before, but even though it says 69% fodder bonus, in the building tab im at 100 percent , not sure if it was because I just loaded the game, but this was the case with all 3 of my cow farms. ( some weird things happens on the load, like 20 plus villagers dying off right away every time I load a save)


In the last pic though, as we can see, when you go to select a grazing area, it doesn't use the fertility overlay. Yet, there seems to be a correlation, as the area where I grow fruit trees and my plant farm had the highest fodder bonus values.

Curious to see If I can make a farm and increase fertility, not for growing things, but to impact grazing..

[Furin]

I'd assume making a farm with nothing but clover and sending cows there to graze will get the job done, both grazing and fertilitywise. Costs some manpower for the farm though, less people to flatten the ground...

although, cows been grazing in this area for about a hundred years plus/minus, fodder never changed

https://steamcommunity.com/sharedfiles/filedetails/?id=2937198601

and that in an area that I had previously converted to a hundred fertility across the board, this is planned as bread basket for the castle whenever it gets done

https://steamcommunity.com/sharedfiles/filedetails/?id=2937198646

so idk what to do to change grazing efficiency, maybe making fields, changing stuff with clay and sand, bulldozing over the plot, rebuilding a field, idk and I have no feasable way to test.

my main is not but my old mining outpost is . I need to post a screen shot later
lol I felt the time needed to Terra form was just too much so I do not bother with it
anymore. If the flatten tool was bumped up to say 5x the effect it would be good.

it depends on how many cows are grazing that rectangle. If you have 20 then it depletes it faster than it regens it. (at least when I tested it back in 7.6) If you have 8 cows like I do it is never an issue and gets it back to 100% pretty quickly. (though you need more barns)

However IMHO the best way is just do a farm with clover and then delete the farm.
This is what I do to plant fruit trees. Farm workers get rid of weeds and rocks and
compost and clover get it to 100% real quick.

From a dev post, the land has an innate fertility max. If you place a farm on desolate ground, it will never get very hi no matter what you do. I to have tested this allot figuring out the max fields can get. The Iddyllic Valley map, a good chunk of that map all th eland can get close to 100%, but the barren waste land maps, you are good if you can get 50 or 60% tops.

This is NOT on desolate ground (barren wasteland) it is done on ground that was
close to 100% and then you plant fruit trees and depleted it. You are getting it
BACK to its max quickly.

If you look at my screens, the fertility around the test area is basically zero. I think I started with something like 12% and after the test the area is at 96%. So yes, they are talking about map values, because this isn't a barren map, it's a lakes map which has the highest fertility potential next to fertile valley. Just the plot I started with was barren.

@Groovy If you delete a farm the ground resets to stony with weeds, try deleting a farm and then immidiatly rebuild it on the same spot, your farmers will have to do maintenance for 2 years again.

@Schwift Master

With the new auto fertilisation you can make huge fields, set them to clover, remove the farmers and let the yards do their magic. This is what the former barren mountain looks like after a couple of years...

https://steamcommunity.com/sharedfiles/filedetails/?id=2947186371

The barren patch to the lower right is an area that cannot be raised ever, no field can be build on it, but you can just slap a big one on top and it will make an intersting looking field.

wow you are dedicated lol I'm on alpine currently and I so go with it. 20% lol

Oh crap I just noticed you are flatten terrain crazy also lol

[Jeffus Maximus]

I'm pretty sure that a recent patch FUBAR-ed fertility. In previous games, I'd graze cows on fields and grow clover and always hit 100% in a few years without fail. In my current game, I have several fields where cows have been grazing, fertilizer spread, and clovers grown for more than a decade now and fertility is stuck in the 30s. No matter what I do, it won't raise anymore. Super frustrating and almost game-breaking.

[chucklestcb]

I have not had much luck with letting cows graze on my fields. They don't seem to do much for the fertility levels on my fields. I feel like that's a bug, or they made it so cows have less effect. It's very frustrating.

This info is so useless!, have an award from me.
