The quality of acidic soil is determined by organic C content produced from rice straw biochar in agriculture. In this context, liquid extract Kappapychus alvarezii (K-sap) used as a enrichment agent. Therefore, research aimed to (i) analyze the character K-sap enriched with different volumes, well (ii) evaluate impact on water holding capacity, size class distribution, aggregate stability index, respiration rate, and chemical characters. treatment tested was volume kg-1 biochar, namely without 0 mL, (iii) 500 (iv) 1,000 (v) 1,500 mL. Each repeated three times placed according randomized block design procedure. area covered K-sap, pore size, amorphous degree increased while surface decreased. addition mL released new peak number associated aliphatic aromatic groups. proportion 1-2 mm, carbon storage, pH, total N, available P K, exchangeable base cations saturation. Meanwhile, concentration Al3+ H+ were decreased solution. results showed that performance quality, ability store improved adding volume.

Abstract Industrial‐scale coffee ground waste has the potential to serve as a nutrient‐rich soil amendment, which would offer growers an opportunity reduce applications of traditional fertilizers. Composted spent grounds (CSCGs) and noncomposted (NCSCGs) were evaluated for their organic N Nitrogen mineralization NCSCGs CSCGs was compared commonly used synthetic fertilizers: urea Milorganite. Net microbial activity measured in fine sandy loam field at 25°C 60% water holding capacity weekly 100 days. Despite C:N 13:1, appeared have slow mineralization. Total inorganic lower both than control throughout 100‐day incubation with no additional system. Greater CO 2 ─C respiration recorded SCGs, suggesting is required breakdown SCGs relative other treatments. may long‐term fertilizer due time it takes mineralize; however, over shorter period, increase nutrient‐ water‐holding soil, can improve plant growth.

Lignin, an organic compound with a complex structure, is formed through the polymerization of structural units linked by carbon–carbon bonds and ether bonds. The question whether lignin labile or resistant to biological chemical degradation in soil, particularly alpine ecosystems, remains unresolved. To address this knowledge gap, we analyzed relationship between phospholipid fatty acid biomarkers abundance components grassland soils from North Tibet, China. Soil samples were collected grasslands, including meadows steppes. relative these before after 210-day incubation period was measured. Our results indicate that decreased during period. Significant relationships found bacteria, fungi, Gram-positive Gram-negative bacteria components. This research conducted under laboratory conditions are optimal for development microorganisms but significantly different Tibet. Furthermore, study contributes understanding soil matter dynamics microbial communities context future global warming.

Abstract Family farming practices are subject to modification as new technologies become available. The act of weeding remove weeds can require a significant investment time from the farmer and thus has been supplanted by use herbicides. Such cause health issues for disrupt soil's biological community, which could ultimately lead reduction in soil fertility over time. present study aimed evaluate consequences applying different concentrations herbicide Reglone® on microbial activity. Experiments were conducted with samples containing varying Reglone®. moisture was adjusted 60% its water holding capacity, microcosms incubated 28 days at 25°C. results demonstrated that concentration 1.3 mg/kg, is Predicted Environmental Concentration active ingredient (diquat), did not impact respiration comparison control. However, two three times higher resulted activity, may negatively nutrient cycling agricultural efficiency soils exposed these concentrations, widely used controlling weeds. It be concluded application exerts influence activity dosages above predicted concentration, 2.6 mg/kg 3.9 ingredient. A decline quality productivity have adverse farmers, potentially leading reduced income an exodus rural areas.
