Field experiments were conducted for up to three years on two different Nova Scotia soils. Tomatoes and cabbage or cauliflower were grown in rotation on the same plots. Crops were amended with either inorganic fertilizer or two sources of three different types of animal manures. Red clover, sweet clover or common vetch were seeded as intercrops with the vegetables. Tomato and brassica yields and plant tissue were analysed for Cu, Mn and Zn; DTPA extractable soil Cu, Mn, and Zn were assessed concurrently. Legume intercrops were analyzed for yield and nutrient content.
