“…At the beginning of the maize cultivation, the solution P in RO increased by 14% for BNA and BNAMg over TSP. Two hypotheses may be related to the higher solution P values observed in the BNA and BNAMg-treated soils: the first includes the formation in BNA and BNAMg of compounds such as calcium nitrate with higher hygroscopicity and solubility because nitrate-containing compounds are generally more soluble and hygroscopic than other P salts [62]. A higher hygroscopicity may have increased water absorption (hydration) by BBFs.…”

The agronomic efficiency of biochar-based fertilizers (BBFs) relies on the synthesis routes, properties, and interaction with the soil–plant system. In our study, BBFs were produced from coffee husk, low-grade acidulated phosphate rock with and without the addition of magnesium (Mg). BBFs were characterized for infrared analysis and the kinetics of phosphorus (P) release in water or citric acid (CA). The agronomic performance of BBFs was tested by growing maize and, in sequence, brachiaria grass in pots filled with two Oxisols with contrasting soil organic matter (SOM) content. Using the same chemical stoichiometric ratio, nitric acid was more effective than hydrochloric and sulfuric acids, creating BBFs with enhanced agronomic performance. The use of Mg in the BBFs synthesis reduced the P released in water. Phosphorus released in CA leachates positively correlated with the P in the shoot of both plants. BBFs produced using nitric acid had higher residual effect on brachiaria grass grown in the Oxisol with the highest SOM. Our outcomes show that the P rate for maize and brachiaria grass should be considered based on P soluble in neutral ammonium citrate plus water in BBFs. BBFs is an alternative to improve the use efficiency of P in Oxisols.

“…[ 135 ] Composite films generally encompass metallic particles, [ 136 ] carbon additives, [ 137 ] and so on which leads to significant changes in the final matrix structure and morphology. [ 138 ] For instance, depending on the metal nature and the polymer structure, the resulted configurations may form as organometallic units incorporated into polymer chains, metal–polymer complexes, metal clusters, or as physically connected nanoparticles to the polymer matrix. [ 139 ] These films are widely applied in such different fields as membrane preparation targets.…”

This review provides a comprehensive overview on applications, preparation methods, and most notably the performance efficiency of polyvinyl alcohol (PVA)-based membranes for filtration of aqueous environments. Incorporation of PVA into the membrane matrix significantly enhances such characteristics as antifouling and antibacterial properties as well as hydrophilicity and permeability in the water and wastewater filtrations. Contribution of different PVAbased modular membranes for water purification targets via a comparative review on previous researches is the main theme in this work. Alongside with the focused topic, some basic theories and principals of blend and composite polymer films as well as polymer fibers are debated before the main discussions. This review will ultimately facilitate further development of PVA membranes for the future investigations.
