What plants put nitrogen back in the soil?
Legumes such as peas, peanuts, beans, clover, and alfalfa are the best plants for adding nitrogen to soil. According to Wikipedia, a legume is a plant that has “symbiotic nitrogen-fixing bacteria in structures called root nodules.” (The specific type of bacteria is called Rhizobia).
Which legume fixes the most nitrogen?Grain legumes such as soybean and peanut use most of their fixed nitrogen for themselves. Forage legumes, such as alfalfa and clovers, are the best crops for companion planting as they can fix substantial amounts of surplus nitrogen under the right conditions.

Do potatoes put nitrogen in the soil?
Potatoes take up little N in the first month after planting (Growth Stage I), but take up about 60-80% of the total N needs during tuber initiation and tuber bulking (Stages III & IV) when most of the total dry matter is accumulated. Nitrogen uptake is nearly complete by the end of Stage IV.
What are the disadvantages of cover cropping?
A cover crop disadvantage for commercial farmers is cost. The crop must be planted at a time when labor as well as time is limited. Also, there is the additional cost of planting the cover crop and then tilling it back under which means more labor.
