“…Humic acid, a pool of humic substances (HS), is prone to form complexes with Zn. However, the stability and solubility of complexes formed depend on the Zn–HA stoichiometry, plant type, HA rate added to soil, growing medium properties, and soil type [ 7 , 8 , 9 , 10 , 11 ]. Therefore, depending on the combination of the factors mentioned above and soil management practices adopted, Zn uptake by crops may be improved or diminished [ 8 , 9 , 11 ].…”

In combination with Zn, HA addition to soil improves nutrient uptake and plant growth through direct and indirect effects of HS [ 9 , 11 ]. Direct effects occur when HA is in contact with the plant cell membrane and tissues, stimulating several plant chemical, physiological, and biochemical processes [ 11 , 12 , 13 , 14 ].…”

“…Direct effects occur when HA is in contact with the plant cell membrane and tissues, stimulating several plant chemical, physiological, and biochemical processes [ 11 , 12 , 13 , 14 ]. The action of HS on plant tissues includes the stimulation of root proliferation, enhancement of H + -ATPase activity in the cell membrane, and changes in the magnitude of nutrient uptake, assimilation, and use efficiency [ 8 , 9 , 11 , 12 , 13 , 15 , 16 ].…”

“…The direct and indirect effects of HA occur simultaneously [ 9 , 11 ], and are linked to the type and concentration of oxygen-, nitrogen-, and sulfur-containing functional groups in the HA structure [ 14 , 15 , 20 ]. Infrared spectroscopy is a suitable technique to reveal the functional groups and specific bonds formed between the metals and HA [ 6 , 7 , 14 ].…”

Zinc (Zn) is an essential micronutrient for plant growth, and Zn deficiency is a global issue, especially in tropical soils. This study aimed to investigate the effects of humic acid (HA) and the Zn addition (Zn sulfate + HA) on the growth of maize and brachiaria in two contrasting Oxisols. The potential complexation of Zn sulfate by HA was evaluated by Fourier-transform infrared (FTIR) spectroscopy analysis. Zinc content and its availability in solution and the shoot and root biomass of maize and brachiaria were determined. FTIR spectroscopy revealed the complexation of Zn sulfate by HA through its S and C functional groups. In both Oxisols, solution Zn increased due to the combined use of Zn and HA. In a soil type-dependent manner, maize biomass and Zn in its shoots were affected only by the exclusive use of Zn fertilization. In the Yellow Oxisol, brachiaria growth and Zn accumulated in its shoot were positively affected by the combined use of Zn fertilization with HA. In the Oxisol with lower organic matter content, HA can assure adequate supplying of residual Zn, while increasing growth of brachiaria cultivated in sequence to maize.

The rise of the energy consumption of developing countries increases the carbon dioxide emission through to the atmosphere that causes global warming. The releasing of the carbon dioxide into theatmosphere is needed to be under control and sustainable because of the natural disaster appearing depending on the global warming that affects human life negatively. Therefore, the investigation of alternative resources is an under obligation instead of fossil-based fuels. The biogas production is one of the methods in alternative fuel manufacturing such as biodiesel, wind power and etc. The mixture of gases %35-45 CO2, %55-65 CH4 are produced with trace amount of other gases CO, H2S, NH3 by using suitable organic wastes after digestion. In this study, the amount of phenolic compound, nitrogen (N), phosphorus (P2O5), potassium (K2O), pH, Humic and Fulvic acid, conductivity properties were investigated in liquid phase before and after digestion. According to obtained results, there are any differences for the amount of N, P, K, while the value of the pH increases after digestion and the amount of the total carbon, Humic and Fulvic acid, the phenolic compounds and conductivity increases after digestion.
