Question

crop rotation for the following crops: lettuce, beans , corn and sweet potato.

Answer 1

Answer:

1. Compared to other crops, corn needs lots of nutrients, especially nitrogen. This makes soybeans a good crop to alternate with corn, because soybeans have nodules on their roots that host bacteria that fix atmospheric nitrogen.
2. Beans and Peas fit into a rotation of 3 or 4 or 5 years. Beans and Peas are legumes, that is, they are members of the Leguminosae plant family. These plants are able to make use of atmospheric nitrogen as a food. They can therefore grow in soils that lack the nitrogenous salts which most plants need.
3. For most gardeners, the best vegetables to plant after lettuce are bush beans, which germinate fast in warm soil and produce heavily in late summer. Other good veggies to plant after lettuce include carrots, cucumbers, squash or a second sowing of basil to carry you through the summer.
4. Crop Rotation: Sweet potatoes should be easy to fit into a crop rotation, while potatoes may be quite difficult. Potatoes should be rotated by 3-4 years with nightshade crops, while sweet potatoes only need to be rotated with themselves. Planting potato seeds is not that difficult, you just need to take good care.
