In the basic version of the game, you can do everything in one phase of growth. Let's assume that the field requires lime. Will describe step by step.
We spread lime, then we use fertilizer. Now we sow using the Rapid A 600S. After sowing, fertilize a second time (100% fertilization). Now we use herbicides. The field texture will change from dark to light so it's easy to see. Until the harvest time, you do not have to do anything on it. The weeds will not grow. This method does not work with a weeder. I hope that the growth of weeds will also depend on the season and weather. Not only like in a vanilla game, from the activities we do on the field
Edit
There are more ways to "cheat"
harvesting>sowing> or sowing with fertilize>herbicide>fertilize
In my opinion, the use of herbicide should affect the condition of the soil (for example, plowing or lime after every harvest where the herbicide was used). Herbicides also have a negative impact (not all) for rape and sugar beet
