“…According to Mikhak et al an increase in availability and longevity due to the slow release of phosphate by the application of surfactant-modified zeolites [ 39 ]. A nanoscale formation of such nutrients as copper in the form of CuO (s) , and iron as Fe(OOH) 3(s) can be applied directly to the plants for enhancing plant growth [ 11 , 40 ]. The advantages of using these nanoscale fertilizers have been discussed extensively in the literature; for example, use of nanoscale micronutrients is also associated indirectly with the enhancement of macronutrient uptake [ 41 , 42 ].…”
