Описание: Phosphate is the "P" in N-P-K; one of three macronutrients that plants need to thrive. Complete with sweeping shots of reclamation land, up-close footage of a dragline in action, and colorful animation of ancient sea life, the Foundation's new Phosphate Mining video shows students the amazing process of mining phosphate and its importance for global food security. For instance, did you know the largest phosphate deposits in North America lie in the Bone Valley Region of central Florida? Furthermore, Georgia, Idaho, Montana, North Carolina, Tennessee, South Carolina, Utah, and Wyoming also have significant phosphate deposits. Scientists believe these large phosphate deposits formed from the skeletons and decomposition of sea creatures that lived during the Miocene period more than 20 million years ago. http://www.nutrientsforlife.org/
