Researchers Develop Slow-release Fertilizers to Promote Rice Production Without Topdressing

Oct 29, 2019

A research team with Hefei Institutes of Physical Science developed slow-release fertilizers to realize rice growing without topdressing.

Rice production has great demands for fertilizer inputs. However, fertilizers are easily to get loss since the rainfall is very rich at the early stage of rice growing, making rice growers keep adding fertilizers to the end of the plant growth. Naturally, the labor and cost for rice growing goes increasing.

To tackle the problem, the team developed slow-release fertilizers based on natural minerals and modified functional materials.

As the slow-release fertilizers have much lower nutrient loss risks than common fertilizers, rice growers do not need to conduct topdressing during rice growth.

And in the rice productivity test, the rice grain yield with slow-release fertilizers (applied only one time) increased by 1,560-2,790 kg/ha (> 19%) compared with that with common fertilizer (applied two times).

So it was very clear that slow-release fertilizers developed by the team could be a promising approach for better rice production with high efficiency but low labor cost.

The work was supported by the National Key R&D Program of China.
