Optimisation of a PCR reaction is often a compromise between the competing demands for precision, efficiency and yield. Although the specific effects may vary, generally, increasing the annealing temperature will increase non-specific primer binding and reduce precision. Increasing the length of the elongation phase will reduce the proportion of incomplete newly-synthesised strands and therefore increase yield. In this case, the potential effect on efficiency is unclear. Increasing the elongation phase would increase the reaction time, but the time taken to ramp down to a lower annealing temperature would be reduced.

Mengel and Kirkby  have proposed that the essential elements be classified instead according to their biochemical role and physiological function, It shows such a classification, in which plant nutrients have been divided into some basic groups these are;

a.) The first group is nutrients that are part of carbon compounds

b.) The second group is important in energy storage reactions or in maintaining structural integrity

c.) The third group has important roles in reactions involving electron transfer or redox reaction

d.) The fourth group is present in plant tissue as either free ions or ions bound
