Potatoes require adequate nitrogen to produce quality tubers and high yields. Organic farming practices are designed to build soil nutrient levels
gradually. In organic systems, nitrogen (N) enters the soil in the form of crop residue and amendments (e.g., manures, composts, and specialty products).
Much of the N added to...
Marine diatoms are a class of microalgae that possess cell walls composed of silica nanoparticles. These organisms actively assimilate silicic acid Si(OH)4 from seawater, polymerize silicic acid to silica nanoparticles by a protein-mediated precipitation process, and then assemble the silica nanoparticles into intricate patterns that constitute the cell wall microarchitecture...
