Abstract Vegetable production in Subtropical China is distinguished by excessive nitrogen (N) fertilization, frequent irrigation, and multiple crop rotations a single year, making it one of China’s most severely impacted agro-ecosystems. The aforementioned variables are closely related to soil nitrous oxide (N 2 O) methane (CH 4 ) emissions. However, not much research has been conducted on the emission characteristics N O CH from local farmers’ practices, impacts chicken manure biochar emissions multiple-cropping vegetable fields south subtropical China. Hence, we field trial measure using static chamber-gas chromatography. Four treatments were used: control (CK) with no fertilizer, 100% chemical fertilization (CN), conventional 30% plus 70%CN (CMN+CN), (CMBN+CN).

Continuous and excessive use of synthetic fertilizers in food production generates strong pressure on agroecosystems. Therefore, it is necessary to study standardize alternatives that promote environmental health, such as biochar. Biochar (a blackish solid obtained from the pyrolysis vegetable waste, industry animal or water processing waste) characterized by its high content mineral carbon, presence functional groups, richness nutrients potassium (K+). Its soils improves organic matter cation exchange capacity (CEC), which promotes crop nutrition. In addition describing biochar manufacturing processes, this chapter aims emphasize role a fertilizer, stimulating effects soil microbiome enzymatic activity, positive plant health. Understanding biofertilizer can be considered an ecological strategy for production. However, agricultural sector must consider limitations fertilizer.

The soil quality of Ultisol, which is indicated by its chemical properties, arbuscular mycorrhizal fungi (AMF), and root nodules, important for soybean growth. Cogongrass biochar enriched with N fertilizer solution using solvent from seaweed extract can change the quality. Using various solvents, this study sought to (i) test impact cogongrass on (ii) examine effects changes AMF, tissue nutrient content, yield. treatments consisted without (B0), enrichment (BN0), (iii) urea Kappapychus alvarezii (BNK), (iv) Sargassum sp. (BNS), (v) Ulva lactuca (BNU). In a randomized block design, each treatment was carried out three times. With or fertilization, improves fertility soil. increase in NH4+-N nitrate-N content greater than unenriched. AMF spores density nodules were reduced following enrichment. When added, there more pods, pod dry weight, total seeds, regular seeds per plant. conclusion, increasing ammonium led decreased spores, infections, nodules. level available P greatly affected components yield Ultisol.

Biochar, an alkaline material derived from agricultural and forestry waste, can ameliorate soil quality by adjusting pH. However, various types of biochar have distinct effects on pH due to diversity in feedstock type, pyrolysis temperature, application rate. Therefore, a meta-analysis was conducted with 598 paired comparisons obtained 104 published studies (January 2010-July 2022) comprehensively depict the response farmland systems across China. The results showed that adding significantly increased acid soils' Still, its neutral soils varied depending biochar's soil's initial raised 5-10% straw (600-800 °C 400-600 °C, respectively). In soils, other (200-400 °C) pH, while 1-5% reduced it. findings underscore importance divergent consequences systems, both factors should be considered choose optimal type for acid, neutral, soils.

Abstract Role of varying C:N ratios biochar to enhance soil health and impacts across types remain inadequately understood. Therefore, this study aimed elucidate the mechanisms change in organic carbon (SOC) fractions greenhouse gas (GHG) emissions under nitrogen‐enriched (NB) application sandy loamy soil. A control (CK; without biochar) four types, including one pristine (PB) three NB (NB1, NB2, NB3), were applied at two rates (20 t ha −1 [L1] 40 [L2]). Biochar levels significantly influenced CH₄ CO₂ emissions. effectively reduced while increased both types. enhanced SOC pools, which is primarily attributed mineral‐associated particulate soils. β‐glucosidase, cellobiohydrolase, β‐xylosidase by NB, particularly a higher rate (L2) compared CK, with more pronounced increases Structural equation modeling showed that SOC. The results provide valuable insights for guiding applications reducing improving fertility, potential benefits diverse agroecosystems farming communities worldwide.
