CNTs AGRICULTURE Carbon nanotubes Great for agriculture That tomato seeds exposed to carbon nanotubes (CNTs) germinated faster and grew into larger, heavier seedlings than other seeds. That growth-enhancing effect could be a boon for biomass production for plant-based biofuels and other agricultural products, they suggest. Considerable scientific research is underway to use nanoparticles wisps 1/50,000th the width of a human hair in agriculture. The goals of “nano-agriculture” include improving the productivity of plants for food, fuel, and other uses. Nanotechnology permits broad advances in agriculture. The impact of multi-walled carbon nanotubes (MWCNTs) on the accumulation/depuration behaviors of contaminants in crop, mustard (Brassica juncea), and the permeability and transportability of MWCNTs in intact mature mustard plants.
