Green bean soil cultivation for commercial small scale farmers Green bean soil cultivation for commercial small scale farmers is also applied in large commercial farms. In a well prepared loose soil, bean roots can penetrate to a depth of 1200 mm. The effective root depth is 450 - 500 mm. [...]
Inoculation of bean seed with nodule bacteria helps the plant to acquire its own nitrogen. Not recommended as a standard practice on green beans. Using nodule bacteria is tricky since there are so many different types. One of the biggest obstacles are inoculating the plant roots with the same strain [...]
Green beans are attached by various pests and because effective pest control is such an important aspect of green bean production, the bean pests must be identified before the correct control measures can be applied.
