Corn-Soybean Intercropping Improved the Nutritional Quality of Forage Cultivated on Podzols in Boreal Climate

Intercropping systems could be a potential source of nutrient-rich forage production in cool climates on podzolic soils common boreal ecosystems. In this study, we evaluated the effects corn–soybean intercropping (IC) nutritional quality forage. Two silage corn varieties were cultivated as monocropping (MC) or intercropped with three soybean using randomized complete block design. IC significantly increased crude protein (22%) and decreased acid detergent (14%) neutral (6%) fibers. Forage net energy, total digestible nutrients, ash, dry matter intake, relative feed value also (p ≤ 0.05) treatments compared to MC. The macro micro nutrients higher than omega 3 fatty (FA) contents (67%) active microbial community plant root zone, which may contribute improvement because soil composition showed significant correlations soluble sugars, proteins potassium These results demonstrate that suitable cropping system increase podzols climates. resultant has high-value animal for livestock climate regions world.
