Salt-affected soil has become one of the major threats to health. However, evaluation biochar amendment effects and underlying mechanisms on physical, chemical, biological indicators used for assessing health salt-affected is lacking. This review summarized performance in improving soils. Biochar addition significantly improved physico-chemical properties by enhancing aggregate stability (15.0–34.9%), porosity (8.9%), water retention capacity (7.8–18.2%), increasing cation exchange (21.1%), organic carbon (63.1%), nutrient availability (31.3–39.9%), as well decreasing bulk density (6.0%) alleviating salt stress (4.1–40.0%). Following incorporation, can also be improved, particularly microbial biomass (7.1–25.8%), facilitating enzyme activity (20.2–68.9%), ultimately plant growth. To properly assess soil, it important select related ecological service functions including production, quality, climate change, human will improve multifunctionality enhance current assessment methods. Finally, limitations future needs research biochar-based technologies soils are discussed. first conducted a global meta-analysis illustrating indicators. Moreover, offers valuable insights developing sustainable tools remediating soil.

Abstract Biochar and organic fertilizer are widely supported to maintain crop production sustainable development of agroecosystems. However, it is unclear how biochar alone or in combination regulate soil functional microbiomes their relationships ecosystem multifunctionality (EMF). Herein, a long-term (started 2013) field experiment, containing five fertilization treatments, was employed explore the effects applications on EMF (based 18 indicators productivity, nutrient supply, element cycling, microbial biomass) bulk rhizosphere [normalizing abundances 64 genes related carbon (C), nitrogen (N), phosphorus (P), sulphur (S) cycles]. Compared with single-chemical fertilization, inputs significantly enhanced most ecosystem-single functions and, particular, increased by 18.7–30.1%; taxa C-N-P-S cycles varying degree. The combined application showed better improvement these compared using them individually. Most populations soil, especially involved C degradation, nitrification, nitrate-reduction, P mineralization, S cycling positive associations at different threshold levels, which ultimately regulated pH availability. These results highlight strong links between agroecosystem functions, as well providing scientific support for inclusion agricultural services amendments. Graphical

Hydrochars as slow-release phosphorus fertilizers for enhancing corn and soybean growth in an agricultural soil

Abstract Hydrochars as carbonaceous amendments rich in porous structures and nutrients can be used promising slow-release fertilizers soil health amendments. Yet, the performance of hydrochars derived from different feedstocks improving crop plant growth phosphorus (P) availability is not well understood. Here, a batch sewage sludge (SS) chicken manure (CM) (SSCs CMCs) were produced at 125 225 °C (SS125/225 CM125/225) to investigate their characteristics performances seedling two representative crops, soybean ( Glycine max ) corn Zea mays ), P an acidic agricultural comparison with triple super phosphate (TSP), conventional fertilizer. Compared CMCs, SSCs more rougher surfaces contained relatively lower contents carbon (C; 32.3–33.3%), hydrogen (H; 3.9–4.69%), potassium (K; 29.2–51 mg g −1 but higher (37.4–85.4%) nitrogen (N; 2.26–4.9%), O-containing N-containing functional groups. The impacts on showed distinct variations. application little effect (i.e., biomass, chlorophyl contents, number leaves), while CMCs significantly increased its total dry biomass by 23.2–66.2%. For corn, both 32.8–92.4% 21.8–69.7%, respectively, compared those un-amended soils. In addition, temperature (SS225 CM225), ones (SS125 CM125) 24.6% 34.9% for 44.8% 39.3% respectively. significant improvement was mainly due direct nutrient supply (particularly P) hydrochars, which supported shoot concentrations. Moreover, hydrochar led rise water soluble (WSP) levels. However, time progressed, these levels fell fixation adsorption via precipitation, electrostatic attraction, ion exchange hydrochars. Contrarily, TSP maintained persistently high WSP levels, increasing leaching risk through profile.
