Plants like sun hemp and alfa-alfa are ploughed back into the field by farmers for several reasons:

1. Nitrogen Fixation: Both sun hemp and alfa-alfa are leguminous plants, which means they have a symbiotic relationship with bacteria in the soil that allows them to convert atmospheric nitrogen into a form that plants can use. This process is known as nitrogen fixation. When these plants are ploughed back into the soil, they release this nitrogen, enriching the soil.

2. Green Manure: When these plants are ploughed and mixed with the soil, they decompose and turn into organic matter, a process known as green manuring. This improves the soil structure, making it more fertile and better at retaining water.

3. Pest Control: Sun hemp is known to have a suppressive effect on certain pests and weeds. Incorporating it into the soil can therefore help to reduce pest populations and control weed growth.

4. Crop Rotation: Growing the same crop repeatedly in the same place can lead to a build-up of pests and diseases, and deplete the soil of certain nutrients. Growing different crops, such as sun hemp and alfa-alfa, and ploughing them back into the soil, can help to break these cycles and maintain soil health.
