A Kazakh scientist has developed a method of obtaining fertilizer from rice husks

Scientists at Kyzylorda's Korkyt Ata University have developed an optimal method for using agricultural waste as an organic biofertilizer, World of NAN reports, citing the regional akimat.

The scientific news was announced by a young scientist Saken Kanzhar at a briefing at the Regional Communication Service.

As the scientist said, the study examined the problems of disposal of agricultural waste, in particular waste rice, modern methods of processing, and areas of application. To obtain amorphous silicon dioxide from rice husks, rice husks were crushed and treated with hydrochloric acid microwave irradiation. The processed product was burned in a muffle furnace at high temperature and amorphous silicon dioxide was obtained.

"Rice husks do not contain any nutrients. I am still doing research to optimize the use of this waste. The goal of the research was to obtain an effective bio-fertilizer for organic farming by rapidly decomposing these wastes. To decompose them quickly, we use cellulose microorganisms from biochar and ruminant animals for rapid growth of microorganisms in the pores. We decomposed this garbage in 3 months and got a new highly effective bio-fertilizer Terra Preta," said young researcher Saken Kanzhar.

Last year he took part in the contest of the Principal of Kyzylorda University named after Korkyt Ata for grant financing for young scientists and won the grant of 2,500,000 tenge.

It is worth noting that in Kyzylorda University named after Korkyt Ata in 2021 there was a competition for research papers of young scientists in order to attract teachers to research activities. According to the results of the competition 4 projects worth 10 million tenge received a grant of the University. Currently, the scientists continue their research.
