Nanobubble Technology Revolutionizes Indoor Farming in New Jersey
The EPA P2 project that Dr. Zhang’s team is leading at NJIT has enabled collaborations with local New Jersey farms and his commercial partners as well as a new spin-off company, PureNanoTech Inc. (PNT), which licensed the patented nanobubble generation technology from NJIT. Supported by NJEDA, this collaborative team evaluated the PNT's nanobubble generator in the field at the Edible Garden, as depicted in Figure 1, which demonstrated the power of air nanobubbles in water irrigation to optimize the growth of staple vegetables such as Basil and Parsley. After a meticulous growth period from seed, both Basil and Parsley underwent a transformative irrigation process utilizing nanobubble-infused water for three consecutive weeks before reaching maturity. The results, as illustrated in Figure 2, are nothing short of extraordinary. Following the nanobubble irrigation regimen, Parsley exhibited a remarkable enhancement in stem diameter and height by over 22%, accompanied by a staggering increase of over 14% in the number of stems. Furthermore, the dry weight of Parsley experienced an unprecedented surge of over 68%. Similarly, Basil experienced a phenomenal growth spurt, with nanobubbles boosting stem diameter and height by over 26%, coupled with a remarkable increase of over 34% in the number of leaves. Notably, the dry weight of Basil witnessed an impressive escalation of over 58%.
These field data underscore the immense potential of nanobubble technology in revolutionizing agricultural productivity and sustainability. As we continue to delve deeper into its applications, we anticipate a paradigm shift in sustainable farming practices that will reduce water and chemical consumption and increase farm productivity
