Optimal cellular function is dependent on maintenance of a normal serum phosphorus concentration. Serum phosphorus concentration is affected by several determinants, the most important of which is ...
Phosphorus has five electrons in its outer energy level ... This creates an area around the junction, called the depletion zone, in which the electrons fill the holes (Fig. 1, closeup). When all the ...
But even so, there wasn’t enough phosphorus to go around. Meanwhile, failed or even faltering crop cycles carried the risk of widespread famine. Soil depletion became an urgent problem.
