GardenWise on Plant Nutrients

We found this great story from Feb. and wanted to share some of these tips on plant nutrients. 

When it comes down to it, most old-fashioned gardeners have plant care imprinted on their fingers. We  add water as needed and allow oxygen to enter the soil by not compacting it. Certain natural soil amendments address specific needs: dried blood or cottonseed meal produce quick, nitrogen-fueled growth, for example, and bone meal provides phosphorus for healthy roots.

If you buy fertilizer labeled with the letters N, P, and K, in percentage amounts, you know how much nitrogen, phosphorus and potassium that fertilizer contains. Those are the three soil elements that plants need the most for growth. It is also good to know that calcium (Ca), sulfur (S) and magnesium (Mg) must be present in significant quantities. Required in trace amounts are certain micronutrients such as iron (Fe). And of course, in order to survive, plants need oxygen (O), hydrogen (H) and carbon (C), which they get from water (H2O) and from carbon dioxide (CO2) in the air.
