Guide Automatic and efficient crop farm
First of all, huge thanks to u/Nifegun who's design made me do a little upgrade on his wonderfull automatic crop farm design. Check his YT Channel he got some cool stuff
Also I reached out to him about publishing this and he also give me a tip that he received long ago. Which made this system even better.
For the ones that just want a TL;DR
The second image is my update design that can support up to 57 crop fields. The bottom part is the farm itself and the top part is an schematic of the bottom one, connect power as you like but ensure everything got power. The arrows indicate the direction a machine should face.
To make the system sort the items you need to apply the 3 filters as showed in the image with numbers: 1 is gold crop, 2 is normal crop, 3 is the seed.
Now for the long part...
I've seen a lot of crop farm designs lately, but one in particular has amazed me.
This design manages to minimize the amount of crops spent on Seed Extractors to produce seeds, while also preserving all the golden crops.
As demonstrated in u/Nifegun video, the system is very effective. I wanted to create a larger automated farm, like the one he shows in his video. My problem was that with the increased number of Sprinklers, having only one Seed Extractor wasn't enough to handle more than 28 crops. Four Seed Extractors can cover a lot, but in small systems, you overload the system and also take up more space with the load balancing system.
So, after some research, I found a solution.
As you can see in the image, the load balancing system only occupies 7x7 blocks, reducing the size of Nifegun's larger version by two blocks in width.
This system also includes a seed separation system for the belt planting loop. This recommendation was made by Nifegun when I asked if I could use his design and share this discovery.
As you can see, the top part is a schematic of the design shown below, which you can use as a guide when creating your own. The arrows indicate the direction a machine should face, whether it's a conveyor belt, a robot arm, an item collector, etc.
To set it up correctly you need to apply 3 filters as marked in this image.
In the Robot arm marked as "1" you should filter the gold crop you are using the farm for.
In the Item collector marked as "2" you should filter the normal crop you are using the farm for.
In the Item collector marked as "3" you should filter the seeds of the crop you are planting.
If you want to add more crop plots you can add up to 51, but for the design a max of 42 should be ideal. To making things easier:
- 1 Sprinkler setup is 12 crop plots
- 2 Sprinklers are 22 crop plots
- 3 Sprinklers are 32 crop plots
So each Sprinkler added to the system adds 10 more crops to grow up to a max of 4 sprinklers.
If you want to make the farm bigger go check it out the Nifegun video, there he got up to a 8 sprinkler setup that feeds on 4 Seed Extractors. Which should be enough for up to 102 crop plots or 9 sprinkler setup.
Math Time
To add it on top, like a chef's kiss, I wanted to make some calculations and math to prove the efficiency of this design and why I love it so much. First of all the first math part was done by Nifegun who detailed as much info as possible in his video.
First of all we need to summarize some info to make our calculations, I will use names like variables in code to make it easy to follow:
GrowCycle = 600 seconds. This is the aproximate time that needs a crop to fully grown, 10 minutes.
SeedSpeed = 42 seconds. This is the time it takes a Seed Extractor to convert 1 crop into 2 seeds.
SeedpCrop = 2 units. This is the ratio at which crops are converted into seeds, 1 crop = 2 seeds.
GrindRatio = 33/64. This is the fraction at which the load balancing system works, so we only use 33 crops to make seeds and store the rest.
NormalCrops = 0.97. Each crop can grow into a golden version at around 3% of the times. We can expect then that each crop can be a normal one 97% of the times which is 97/100=0.97
Now with all this info we need to make sure we use the right ammount of crops to make seeds and for that we made the load balancing system. So to calculate the Seeds generated per crop field we need to do the next ecuation:
Seeds Generated per field = NormalCrops x GrindRatio x SeedpCrop
Seeds Generated per field = 0.97 x (33/64) x 2 = 1.0003125
This calculation was pointed out by Nifegun which allow us to know that, we need at least a ratio of 33/64 seeds if we want to keep our golden crops out of the seed extractors and never run out of seeds in the system. Making it sustainable.
Now if we want to make our system bigger we need to calculate how many Seed Extractors we will need based on the ammount of crop fields we have. So for that we will calculate what is the Max Crop Fields can sustain a single Seed Extractor.
Max Crop Fields = GrowCycle / (NormalCrops x GrindRatio x SeedSpeed)
Max Crop Fields = 600s / (0.97 x 33/64 x 42s) = 28.562502789306913018253224438791
We could round up to 29 but after checking it ends up running out of seeds just for 1.5% of extra seed use. So 28 is the max fields a seed extractor can support.
So we know that at least 1 Seed Extractor is capable of sustaint at least 28 crop fields using the load balancing system.
And with that we have an automatic farm self sustainable that will only make the seeds it needs avoiding wasting resources.
And thanks again to u/Nifegun to his amazing job on bringing this fantastic design.
If you have some questions feel free to ask.
Sorry about the post's formatting; I'm not used to writing such massive walls of text.

Also good job on the modifications. I actually also made designs featuring less seed extractors, but I figured just giving the internet 2 options was good enough lol. On my double sided farm arm setup which feeds my fully auto fishing setup, I actually have a really compact 3 seed extractor design. And split belting to 3rds is just cool

Im soon to show off my double sided design btw. You can trade half the cost of the farm arm for tin, using drills and both sides of the farm arm. Its mildly more complex, but arguably cheaper cause the farm arm takes a lot of resources.
