These nutrients are not from fossil source like many inorganic fertilizers. So I suggest the best means is that organic materials having a high percentage of nutrients are better used to grow more woody plants to be used as fuel. Charring these materials and we make many nutrients, like P, unavailable and some like K and N go off into the air. Composting these materials further increases the amount of available nutrients by better holding on to the nitrogen and planting may take place immediately -compared to green manures. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Reducing fossil fuels (and inorganic fertilizers) and it becomes more important to make best use of our nutrients.
