Care
Soybean (Glycine max) is a type of legume of the Fabaceae family native to east Asia. It is mainly known for its edible bean which provides good proteins and oil. The main countries growing soybeans are the United States (32% of world total), Brazil (31%) and Argentina (18%).
Soil
Healthy, fertile, workable soil is beneficial for growing soybeans. Especially loamy soil works well due to its ability to keep the soil drained but still moist. Soybean plants prefer slightly acidic soils with a pH around 6.5. The crop can be grown from sea level up to an altitude of 2000 m.
Climate
Soybeans are usually grown in cool, temperate regions like the midwestern United States and southern Canada, but tropical climates like Indonesia also give good results. This crop can grow almost anywhere with a warm growing season, ample water, and sunlight. Soybeans can be damaged by subfreezing temperatures, but they are less tender than several other crops, such as corn. Soybeans also need a growing season with temperatures between 20°C and 40°C and at least 500 mm of water. Day length plays an important role in soyabean crop production. Good yield is achieved where the length of day is less than 14 hours.
