The major problems that soybean small-holders face are the lack of drying facilities, inadequate storage facilities and inadequate drying and lack of cleaning equipment. These problems are present mainly in rural areas of tropical and subtropical regions. On the other hand, the major problems that medium-scale soybean farmers face are pests, diseases and weeds, labour shortage, especially in Asia where most of the operations of soybean cropping are manually done, lack of high quality seed, lack of cultivars resistant to diseases or insects, lack of economical resources to buy the required inputs (fertilizer, herbicides, chemicals), poor control of pests and diseases and drought.
