These elements are sometimes called minor elements or trace elements, but use of the term micronutrient is encouraged by the American Society of Agronomy and the Soil Science Society of America. The micronutrients are boron (B), copper (Cu), iron (Fe), chloride (Cl), manganese (Mn), molybdenum (Mo) and zinc (Zn). Recycling organic matter such as grass clippings and tree leaves is an excellent way of providing micronutrients (as well as macronutrients) to growing plants., <a href='http://delicious.com/tag/manganese+%28mn%29'>delicious.com</a></p> http://www.miningweekly.com/article.php?a_id=147047 http://www.miningweekly.com/article.php?a_id=146120 http://www.businessday.co.za/articles/topstories.aspx?ID=BD4A872128 http://www.miningweekly.com/article.php?a_id=148882
