Abstract BACKGROUND The utilization of chemical fertilizers is a key measure for maintaining tea yield and quality, but excessive use has negative environmental impacts. substitution fertilizer with organic been promoted to sustain crop soil quality. However, knowledge gaps regarding the effects on quality in plantations still exist. RESULTS A field experiment was conducted investigate influence treatments (i.e. 25% partial substitution: biogas slurry + green manure formula fertilizer, BFG; sheep OFF; 100% complete manure, OG) nitrogen efficiency southwestern China. Results showed that all slightly increased pH, significantly matter by 13.22–14.88% compared conventional fertilization (CF). BFG treatment most effective enhancing index, showing increases 16.80%, 8.37% 24.87% higher than CF, OFF OG treatments, respectively. Tea under BFG, 11.97%, 13.58% 5.90% amino acid content 7.78% decreased polyphenol/amino ratio 6.87%. Additionally, greatly young sprouts 70.71%, 82.54% 34.28%, CONCLUSION Overall, could effectively improve while yield. © 2024 Society Chemical Industry.

Nitrogen (N) fertilizer application is one of the causes soil acidification at tea plantations. However, effect N on characteristics plantations with different acidities remains unclear. In this study, field experiments were conducted to investigate effects nitrogen rates pH, pH buffer capacity (pHBC), exchangeable total acidity (ETA), base cations (EBCs), and cation exchange (CEC) in topsoil non-acidified (NA), mildly acidified (MA), heavily (HA) The results showed that Al3+ (E-Al) CEC HA > MA NA all plantations, whereas EBCs saturation percentage (BSP) < NA. 4.0, EBCs, BSP decreasing trends increasing application, E-Al an trend. a small trend increase H+ (E-H), E-Al, trends.

Organic-based fertilizers have been ratified to be effective in ameliorating tea growth and the fertility of soil. However, effect integrated fertilization on quality chemical properties soil gardens are unclear. To address this, from 2020 2021, five different treatments were carried out greenhouse Tea Research Institute, Hangzhou, CAAS, including CK (control), NPK (chemical fertilizers), RC (rapeseed cake), NPK+B fertilizer + biochar), NPK+RC, investigate effects fertilizations chemistry quality. The results indicated that NPK+RC significantly improved amino acid catechin concentrations young shoots, stems, roots compared CK. plant parameters, e.g., height, no. leaves, mid-stem girth, fresh weights stems increased with (NPK+B NPK+RC) solo organic inorganic fertilizers. chlorophyll contents (Chl a, Chl b, a+b) generally higher than (37%, 35%, 36%), (14%, 26%, 18%), (9%, 13%, 11%) treatments. Integrated buffered acidic garden decreased C:N ratio. also soil’s total C (31% 16%), N (43% 31%), P (65% 40%), available 58%), K (70% 25%), nitrate (504% 188%), ammonium (267% 146%) RC. macro- (Mg Ca) micronutrients (Mn, Fe, Zn, Cu) by (100% 72%) (49%, 161%, 112%, 40%) (88% 48%) (47%, 75%, 45%, 14%) all positively correlated (amino acids contents) growth.

The Chinese Chernozems face extreme challenges of soil degradation and crop productivity decline. Biochar-based organic fertilizer (BOF) is effectively applied to improve yield quality. Nonetheless, the mechanisms involved in enhancement interaction with root traits, quality, microorganisms after BOF application remain unclear. Herein, a two-year field experiment three rates [3.0 Mg ha−1 (BOF3), 6.0 (BOF6), 9.0 (BOF9)] was conducted evaluate impact on microorganisms, no as control treatment (CK). Compared CK, increased maize by 9.1 ∼ 32.0 % second year application, highest (16.1 ha−1) obtained BOF6. plant growth index 29.7 98.9 %, mainly attributed increase volume (2.4 57.4 %), aboveground biomass (31.4 44.0 nitrogen (N) uptake (123.2 216.0 %). quality not only topsoil (27.7 31.1 %) but also subsoil (22.7 25.1 BOF, particularly two (BOF6 BOF9). This ascribed notable microbial carbon, total N, NH4+-N, N-acquiring enzyme activity (normalized leucine aminopeptidase alkaline phosphatase). Moreover, abundance Actinobacteria, Mortierellomycota at 0–40 cm, Chloroflexi 0–20 Acidobacteriota, Ascomycota 20–40 which confirmed their key roles activating nutrient subsequent enhancing stimulating growth. Overall, biochar-based rate promising regime enhance regulating keystone taxa, thereby boosting Chernozem soil.

Heavy use chemical fertilizers and cover cultivation to produce off-season shoots results in soil degradation a decline productivity. This paper introduces an amino acid fertilizer, fish protein replace portion investigating the effects different fertilizer combinations on growth, shoot yield, properties, clarifying growth-promoting mechanism fertilizer. Results showed that after replacing 45 kg compound with 10 20 kg, respectively, (1) yield increased by 23.24% 26.19%, respectively; (2) leaf root growth were enhanced, thick proportion increased, topsoil decreased; (3) pH, contents available phosphate, organic carbon, microbial biomass carbon nitrogen, enzyme activity increased; (4) nitrogen (N) phosphate (P) leaves while N/P K/P decreased. Overall, can promote through supplying sources sources, enhance activity, thus phosphorus activation increase effectiveness, then expand scale foraging ultimately improve nutrients absorption yield.
