In 1904, the German scientist Lorenz Hiltner introduced the term “ rhizosphere ”, based on Beijerinck’s findings and the discovery of several other nitrogen fixing, soil-dwelling bacteria. WebPeas respond best to a low nitrogen fertilizer, such as 5-10-10 fertilizer, applied just as the sprouts begin to emerge from the soil. This will fuel yours peas’ growth and encourage a good harvest. Avoid high-nitrogen fertilizers, since this will encourage leafy growth but decrease the amount of pea pods the plant produces.
