Precision Farming Enviro Score Not Updating?

[Insert_Text_Here]

So I just got precision farming. I just adjusted the ph and nitrogen of the field to the optimal level but my environmental score isnt updating and still showing 50% for both categories. Is there a reason why the scores haven't updated? Does it only do this on harvesting or is there a bug?

I also have only just begun using the Precision Farming DLC so I'm just learning it as well. So far I have done everything you have done and my fields show "perfect" levels of PH and Nitrogen. My two fields still show environmental scores of 57 and 60 respectively. One has wheat, the other grass.

On a side note I found I had to apply solid fertiliser to my wheat field once growth had begun (even though I had applied slurry before seeding). I found the nitrogen levels had fallen. Applying solid fertiliser fixed this and brought the levels back to optimum. I also noticed that I saved a lot on fertiliser as it was applied at a rate specific to the field's needs. Pretty good I think.

I then checked my grass field (I have cows) and found the opposite. Now that grass was growing, it seemed the nitrogen levels were a bit too high for grass. Nothing much i can do about that I guess.

I'll let you know if my field environmental scores change.

Mine is currently 62 for my field (No Man's Land). Soil sample and tillage are at max, but weed control, ph, and nitrogen are at middle. PH I put down lime before I planted since PH is determined by soil composition not crop type, planted, rolled, then solid fertilizer for nitrogen since fertilizer is based off of crop type. Both are giving me perfect scores when I look at the ground and it gives me the side graph with ground info but for some reason the enviro score isn't updating which would be fantastic for the sell bonus cause of wooden planks and furniture.
This is good to know though I'll have to test this once I get cows, but it calculates the fertilizer spread based on whatever crop is underneath it. I wonder if they'll eventually add crop rotation in the way seasons did in FS19 to change fertilization requirements.

PH and Nitrogen scores only update when the crop is harvested.

@ Kipsley - I think Oilseed radish has to be plowed in to obtain the nitrogen bonus.

There are still a couple of oddities with PF:
Despite what it may say in the notes, using slurry or manure has no effect on your nitrogen score, simply reduces the amount of other fertilizer you need to use.
To get the max nitrogen score you need to have the crop sensor turned on when fertilizing a growing field.
Although grass fields do not produce weeds, you still need to use the JD Spot weeder on them to get max weed control score - just turn it on for 1 sec.
Scores at c.97-98 can be brought back to 100 by repurchasing field info, even though nothing has changed.
Just my observations.
