THE SOIL PROBIOTICS FOR AQUACULTURE

A unique combnation of microbes at work


Aquaculture suffers from bad soil conditions and lead to the higher
mortality, disease incidence and decrease in yield. Soil deterioration in
aquaculture ponds is mainly due to the excess feed, fecal matter of the
cultured organism such as shrimp and fish, dead animals. Two major
gases cause problems namely hydrogen sulphide and ammonia. Unless
we understand the nitrogen cycle and sulphur cycle in the bond
ecosystem, solution is impossible. Nitrogen from aminoacids, proteins,
nucleic acid and minerals from feed supplements, etc., from organic
matter accumulated as mentioned from the sources above is converted
to ammonia by group of bacteria called nitrogen reducers. Sulphur from
sulphur containing amino acids, proteins and minerals are converted to
hydrogen sulphide by sulphur reducing bacteria. Nature has both
oxidizing and reducing bacteria and in perfect harmony. In a man-made
system one overtakes the other. This is where a soil probiotics work.
Unlike some commercial products which use bacteria that work only in
presence of light or bacteria that can thrive only in anaerobic conditions,
our product has consortium of bacteria that work with different
mechanisms without need for light as well as grow well at both aerated
and anoxic conditions.

 

Product


It is a yellowish brown powder with characteristic smell but not
unacceptable. This has a consortium of bacteria capable of converting
hydrogen sulphide to sulphate and ammonia to nitrate and subsequently
into atmospheric nitrogen. The enzymes produced by them degrade
starch, cellulose and protein into simpler material to be used by the
probiotic bacteria.

Application


There are two suggested ways of application. You can apply it by mixing
it with soil during the pond preparation. Use 5 Kg for 1 hectare pond
evenly distributed. Second one is a periodic application of 2 Kg mixed in
garden soil or zeolite properly moistened. Unlike other products since
the bacteria are immobilized no to worry about getting dissolved in
water without reaching the bottom. Use discretion in dosage based on
condition of pond. Doses up to 10 Kg / hectare were found to be
harmless.
