Dear Mr. Oliviera,
there is a positive correlation between the population density of microbes
in the soil and soil fertility. Therefore, application of any biodegradable
organic material to the soil causes the microbes in the soil to multiply. In
the process of multiplication, they absorb minerals from the soil. The
textbooks say that they cannot absorb minerals from the soil, because the
soil minerals are insoluble, but that is not true. Water is a universal
solvent, and the capillary water in the soil always contains all the soil
minerals dissolved in it, albeit in a very small concentration, which can be
measured only in P.P.M. or P.P.B. If you applied pure sugar to the soil, the
soil microbes increase their numbers 500 to 1000 times within 24 hours.This
shows that the microbes can take up minerals from the capillary water in the
soil. The minerals sequestered in their cells are now in the form of
proteins, co-enzymes etc,.which are highly water soluble. When the organic
matter has been exhausted, the microbes die of starvation, and when their
cells lyse, the minerals released in the soil are taken up by plants. Thus,
even a relatively small quantity of high calorie organic matter applied to
the soil can lead to an increase in the soil fertility. Literally thousands
of farmers in Maharashtra state in India are nowadays following this tactic.
They apply to their field just 25 kg sugar per acre, once every three
months, and no other chemical fertilizer or organic manure. And yet they get
very high yield from their crops, equivalent to the yield that they used to
obtain by applying costly chemical fertilizers.
