Waste milk humification product can be used as a slow release nano-fertilizer

Y. Zhu, Y. Cao, et al.

The rising demand for milk has resulted in significant waste, but innovative research by Yanping Zhu, Yuxuan Cao, Bingbing Fu, Chengjin Wang, Shihu Shu, Pengjin Zhu, Dongfang Wang, He Xu, Naiqin Zhong, and Dongqing Cai reveals a solution. They developed an artificial humification technology that transforms waste milk into a slow-release nano-fertilizer, showcasing its potential to boost agricultural yield and root growth in plants like chickweed.

Abstract
The increasing global demand for milk has led to a rise in waste milk disposal. This study presents an artificial humification technology to convert waste milk into a slow-release nano-fertilizer. KOH-activated persulfate is used to transform waste milk into fulvic-like and humic-like acids, which are then combined with attapulgite to create a slow-release nano-fertilizer. Pot experiments using chickweed showed improved yield and root elongation with the nano-fertilizer, suggesting its potential for agricultural applications. Further field experiments are needed to validate these findings.
