Soybeans
About This Crop
Soybeans (Glycine max) originated in East Asia and are now cultivated worldwide as a premier protein crop. This legume thrives in temperate climates with warm summers (20-30°C) and requires 100-130 frost-free days with adequate rainfall (500-800mm) during the growing season. Soybeans prefer well-drained, fertile soils with good organic matter content and perform best in areas with hot, humid summers and moderate rainfall. The beans are nutritionally exceptional, containing all essential amino acids and are rich in protein (35-40%), healthy fats, fiber, and isoflavones. As a nitrogen-fixing legume, soybeans form symbiotic relationships with rhizobia bacteria, reducing nitrogen fertilizer requirements while improving soil fertility for subsequent crops.
