An article about the development published in the journal of Agricultural and Food Chemistry. "The advantage of slow release of the active substance that acts a fertilizer for the first three months of plant growth with no supplements", the article says.

Scientists have made compressed tablets from a mixture of traditional fertilizers - ammonium nitrate, adding a biodegradable polymer, poly-3-hydroxybutyrate (П3ГБ). In this part of the tablets optionally coated with a shell polymer for even more slow dissolution in the soil. After that, the researchers tested the new fertilizer in experiments with wheat (Triticum aestivum L.). Samples of wheat were grown using ammonium nitrate in its pure form and with the use of these two types of tablets.

The results of the experiment showed the highest efficiency of coated tablets. Biomass grown with their use of wheat was 25% larger than that grown using conventional fertilizers. Scientists say that the Supplement, a biodegradable polymer allowed the effective substance is released into the soil much longer than usual - up to three months. It can be placed in the soil during sowing of seeds and not processing plants. This approach allows also to reduce emissions of harmful substances into the environment.
