Hello crop rotators,
Crop rotation isn't just about the nutrients the plants take up. It's also very helpful in the fight against pests and diseases, it keeps your soil in good condition and helps with weed control. Because some pests and diseases remain in the soil for years after their hosts have departed, the only option is to grow another crop in the same place.
However, on the subject of plant nutrients, beans love fertile ground, that is why cottage gardeners have made bean trenches for centuries. It's true that beans fix nitrogen into the soil but they still need other nutrition.
There are fewer and fewer chemicals available on the market for amateur gardeners so good husbandry, including crop rotation will become even more important in years to come.
