Highlights of the Recommendations of Inter Ministrial Task Force On ...

4. Processing:-
i) After controlled aerobic Composting by the specific microbes the
decomposed material is passed through mechanical rotary screen of
different sizes 40 mm, 32 mm, 25mm, 8mm and 4mm sieves.
ii) The enrichment of organic manure is conducted with different bifertilizers
, major and micronutrients (if required depending upon the
soil test value , cropping system and agro-ecological conditions)
iii) Thereafter weighing , bagging , stitching and stacking is performed
iv) For keeping the required population of beneficial microbes alive 17-20
% moisture is necessary.
All this well depicted in Flow Chart and Platform
diagram.
