Soil on organic farms is often deficient in available phosphorus. Is this a serious problem, or are low levels simply a reflection of the way we measure the nutrient? Cathy Welsh, a recent masters of science graduate from the University of Manitoba’s soil sciences department researched this question. Working with Mario Tenuta, Welsh studied the […] Read more

Crop rotation key to increasing grain’s nutrient content – Organic Matters
A long-term study at the University of Manitoba is adding more weight to the theory that crop rotations in organic agriculture can affect nutrient content in grain. Martin Entz, Soleil Turmel and Keith Bamford of the university’s plant science department compared the concentration of 10 mineral nutrients in wheat grown organically and conventionally in two […] Read more
