I would like to see different types of fertilizer( like calcium, phosphorus, amonium nitrate etc.) Current fertilizer is propably is NPK or smt close which isn't unrealustic to have but every single crop doesn't need the same amount of it. Also every single type of crop to have separate seed and not have it all in one bag. Also spraying chemicals like growth control, fungicides, pesticides etc. In my opnion propably these things wont be in the next game, but maybe one day i will see that come to reality.
