Scientists developed "smart fertilizer"

According to the head of the works Tatiana Volova, Professor of SibFU and the Head of Laboratory in the Institute of Biophysics KSC of SB RAS, development of a new generation of drugs with the use of bio-decomposable materials which decompose under the influence of the microflora to innocuous products and provide a gradual release of the active principle into the soil, is the newest area of research in the field of agriculture. For example, nitrogen is one of the elements, which is often lacking for the growth and development of plants. Plant-available nitrogen in the soil is usually small. Moreover, its compounds are chemically very mobile and easily leached from the soil. In this connection there is the task of developing such forms of nitrogen fertilizers that provide slow release nitrogen and the constancy of its concentration in the soil.

"The key point for the development of such drugs is the presence of environmentally safe and bio-decomposable material. We have developed and implemented the technology for the synthesis of bio-decomposable polyesters of microbiological origin, is effective as a material for products for biomedical applications, and also explored patterns of their decomposition in soil and other environments" — says Tatiana Volova.

To create a slowly decaying structures, the researchers used a biodegradable polymer called poly-3-hydroxybutyrate. Scientists mixed powder of the biopolymer with wood flour and ammonium nitrate. The resulting mass was pressed into tablets and used in the experiments with wheat. Disintegration of biodegradable tablets with the addition of ammonium nitrate.
