The nutritional value of edible mushrooms is due to their high protein, fiber, vitamin and mineral contents, and low-fat levels [8, 10].They are very useful for vegetarian diets because they provide all the essential amino acids for adult requirements; also, mushrooms have higher protein content than most vegetables. elements (the so-called major plant nutrients): ions of. The series discusses the role of nutrients in plant metabolism, their reactions in soil, and solutions to overcoming deficiency. These 14 elements, along with carbon, hydrogen, and oxygen, are called the 17 essential inorganic nutrients, or elements. Macronutrients: used in large quantities by the plant. We find that restoration of plant biodiversity on a nutrient-poor, unfertilized soil led to greater increases in soil fertility than occurred when these same plant species grew in monocultures. 17. Sulfur (S) Plant process: Sulfur is a constituent of amino acids in plant proteins and is involved in energy-producing processes in plants. These nutrients are sometimes broken into two categories: macronutrients and micronutrients. In many cases, plants suffer a nutrient deficiency not because there isn’t enough in the soil but because the condition of the soil prevents it from being taken up readily. • Major function in photosynthesis • An essential part of enzymes in plants • Increased fertility (number of grains per head) • Increased grain quality • High pH inhibits Cu uptake • Inhibited by excessive N and high pH Deficiencies made worse by: • High soil pH • Excess potassium, phosphorus or other micronutrients can All the 17 elements mentioned above are essential elements.
