Rune Factory 4: Soil Stats and Crop Stats Guide

Two "number" stats?! Speed vs growth?! Two "quality" Stats?! What is going on in the information windows?!
Once you break it down, it's actually not so bad! Ok, it's still bad, but not as bad.


Soil Stats

Grab a magnifying glass from the Flower Shop and use it on an untilled part of a plot, making sure the entire tile is highlighted in red, to see the plot's soil stats:

Targeting the entire plot shows you the stats for all of the soil in the highlighted plot.
[Overall] 16.36
[Spd.] 8.81    [Ql.] 8.93
[No.] 8.33   [Sz.] 9.11
[Grw.] 2.2x    [Ql.]+0.17
[Health] 113   [Def]. 32

All crops in a 2x2 plot share the same soil stats. These five soil stats increase with successful harvest of crops anywhere on the plot. 

In our example:

[Overall] 16.36

[Overall]Level of the soil. Increases base Speed, Quality, Number, Size, which is said to be what the plot gravitates to when left to fallow. (Will have to verify since I'm not clearly seeing this.) Increased with successful harvest. Maxes at 16 regardless of decimals following. 

[Spd.] 8.81    [Ql.] 8.93
[No.] 8.33   [Sz.] 9.11

[Spd.]Base speed at which crops grow on this plot. Multiplied by Growth Rate and added to crop progress every day.
[Ql.]Base quality points. Multiplied by crop Quality Rate and added to crop progress every day. 

If enough Quality accrues during a crop's time growing on a plot, the crop may level up.
[No.]Max number of crops that can be harvested with Bumper Crop.
[Sz.]Boosts progress towards Gigantic Crop every day when conditions are right (four fully grown same plants in single plot). Might involve other factors such as in-season, level, etc.



Soil Stat Modifiers


These stats affect the soil stats and can be temporarily manipulated by chemicals such as Formula A, B, C, Wettable Powder, and Greenifiers.

[Grw.] 2.2x   [Ql.]+0.17

[Grw.]Multiplier for soil Speed from using Formulas. Growth.

Increased by using Formula up to 5.00. Decreases when crops harvested from the plot. Normalizes to 1.0. 
[Ql./No./Sz.] +Added to daily soil Quality/Number/Size increase. 

Quality+ increases from Greenifiers up to 2.00. Size+ increases from Gigantizer, decreases from Minimizer. Unsure where Number+ stat comes from, but it's there sometimes. Decreases when crops harvested from plot. Normalizes to 0.


Ql.+ stat is particularly important when making the jump from Level 9 crops to level 10 crops.

Soil Health

Last but not least, the two numbers that keep the wheels in motion.

[Health] 113    [Def]. 32

[Health]HP of soil. Allows crops to grow healthily. 

Decreases when crops harvested and when chemicals are used. Normalizes to HP respective to soil level. Increased up to 255 by fertilizers (withered grass, corn, clover hoed onto the plot).
[Def.]Protects this plot from typhoon damage if above 32 defense. 

Increased up to 63 by Wettable Powder. Normalizes to Defense respective to soil level. Decreased by 8 points each time a typhoon's RNG selects the plot to be damaged.


Crop Stats

Then use the magnifying glass on a crop to see the crop's stats:

Don't be intimidated by all the information! The top two line are unique to the crop.
The bottom four lines are just the plot's soil stats rounded down.
[Crop Lv.] 2   [No.] 3
[Grw.] 31%   [HP] 185
[Overall] 16    [Spd.] 8
    [Ql.] 8   [No.] 9   [Sz.] 9
[Grw.] 2.2x    [Ql.]+0.17
[Health] 113   [Def]. 32

In the crop stat info box, the actual value are simply rounded down.

[Crop Lv.] 2   [No.] 3
[Grw.] 31%   [HP] 185


[Crop Lv.]Crop level. Increases sell price and effectiveness of crop as an upgrade or ingredient.
[No.]Number of crops expected upon harvest. Decreased if plant has withered, or if Poor on Harvest report. Increased if Bumper Crop.
[Grw.]How far crop is into being harvestable.
[HP]Health point of the crop itself. If HP of trees or Dungeons seed reaches 0, they will die/disappear upon next use. Increased up to 255 by fertilizers (withered grass, corn, clover hoed onto the plot).

How Much Each Crop Increases Soil Stats

This is where I must stand on the shoulder of giants and refer to someone else's research.

User Anketam posted an extensive table on the increase each crop gives to your soil. The guide discloses that some numbers may be slightly inaccurate due to plots changing after harvests, but this is the most comprehensive foray I've come across in my external research.

The amount of effort put in to obtain such extensive amount of data is impressive, and a lot of the explanations have been very helpful towards explaining what each stat means.

That said, I do disagree with some of the conclusions drawn in the guide (such as the definition of the "Overall" stat, and Speed and Growth being interchangeable), but unless someone has knowledge of or dissects the actual source code, all information regarding these stats is simply a player's interpretation of a term and conclusion drawn from theorized testing, and I thank Anketam for posting this information.
