To ensure that the soil is as efficient as possible for plant growth, and therefore resulting in a larger crop, Seasons 19 requires you to plan several moves ahead. Crop rotation is one of the biggest and, at the same time, not quite clear changes when compared to the basic version of Farming Simulator 19.
Planting the same plant in the same field for several consecutive seasons is not a good idea (with a few exceptions). Thanks to crop rotation - planting different types of plants alternately - we will help the soil to remain fertile. However, we can't do this without proper knowledge - not every plant "gets along" with others. The positive aspect of the crop rotation is that by using it effectively, you will improve the quality of the soil, which is seen in the game as its pre-fertilization.
Use a tool called "Crop Rotation Planner", available in the mod's menu, to manage your crop rotation. Each of the "Rotation" columns represents one of the plans that you can apply to your fields. These choices are completely noncommittal and sometimes, they may even be impossible to carry out (for example, when you want to plant something different after harvesting the previous plant but the temperature is too low). Then, you can always change the rotation fields to see how the result will change with another plant and come up with a new plan.
Starting from the top or bottom, select plants you want to grow in one of the columns. Then, move on to the next row. A small number indicating a percentage value of how much you can harvest with the current strategy will appear next to the selected plan (the maximum value is 1.20 which means 120%). By default, we read the table from bottom to top: the plant selected below determines the result for the plant above - in the next rotation (next year).
The key to success is to rotate crops to get both a high score in subsequent rotations and meet your cultivation/profitability requirements for the current year. Also, there is one option called "Fallow" - you leave the soil for one year (you aren't doing anything with it) to "rest". Thanks to this option, the soil accumulates additional minerals that will allow for more effective plant growth next year. This is a very convenient option when you have several fields and you focus on their maximum performance. Remember to plan the harvest wisely - you don't want to be left without anything when some of the plants turn out to be necessary for us (for example, cereals for animal feeding).
An efficient and well-planned crop rotation, fertilization and plant care can now give you 120% yield when compared with the maximum yield from the main game.
