New Cotton Fertilization Method Developed in China

Aug 07, 2019     Email"> PrintText Size

Researchers have devised a new method of efficient fertilization of cotton with lower nitrogen leaching in sandy soil in northwest China's Xinjiang Uygur Autonomous Region, according to the Chinese Academy of Sciences (CAS).

Fertilizers like nitrogen are necessary for the plant's growth, however the ease with which they leach into sandy soil through traditional flood irrigation methods results in low nitrogen uptake efficiency and cotton productivity.

A research team from the Xinjiang Institute of Ecology and Geography of the CAS conducted research in the oasis zone around the Taklimakan Desert, an important cotton growth area.

The researchers reversed the order of the traditional irrigation and fertilization. When the water was drained after irrigation, the urea with high nitrogen was added into the wet soil and was found to be dissolved in mud, said the study paper published in the journal Agricultural Water Management.

The nitrogen can remain in the cotton roots for a long time, which contributes to a high nitrogen recovery efficiency, said the paper.

"This new fertilization method contributes to higher cotton productivity. We can also use 20 percent to 30 percent less water to maintain the yield compared with the traditional methods," said the researcher Zeng Fanjiang.

This result is also of great significance for the scientific management of the nitrogen leaching of cotton as well as other crops grown on sandy soil under traditional flood irrigation conditions, according to the CAS. (Xinhua)
