The problem of soil fertility imbalance in hilly agriculture is prominent, and accurate estimation potassium balance key to achieving precision fertilization at the regional level. Crop distribution has a significant impact on balance, but studies with focus crop cultivation types are scarce, especially regard areas. In this study, spatial characteristics under different cropping conditions its influencing factors were analyzed for region. results showed that (1) rapidly available (RAK) slowly (SAK) content 0–20 cm layer ranged from 29.37 122.07 mg kg−1 472.31 772.77 kg−1, respectively. (2) equilibrium status varied considerably among systems deficit was greatest rapeseed–maize rotation, reaching −129.50 kg K ha−1 yr−1. difference deficits between rice–rapeseed wheat–maize rotations not significant, −46.79 yr−1 −44.07 yr−1, respectively, only rice–wheat rotation surplus. Due low absorption crops, value higher than rice wheat can achieve degrees Rapeseed planting generally under-applied potassium, could reach −70 (3) Climate, topography, anthropogenic activity, explained 20.8% variance balance. Anthropogenic activity such as roads population density had influence, 0.797. Topography average annual precipitation weakest influences. These findings emphasize importance also provide evidence formulating efficient measures resources management.

Analysis of Consumer Preferences for Green Tea Products: A Randomized Conjoint Analysis in Thai Nguyen, Vietnam

Sustainability, Год журнала: 2024, Номер 16(11), С. 4521 - 4521

How local economies can successfully develop remains an important issue for any developing country. One mechanism promotion of economic development is government-driven policy. The problem that it not clear whether public-led attracts consumers and which factors are relatively significant boosting particular goods. This paper examines attributes green tea products likely influencing consumer preferences, focusing on the Thai Nguyen area in Vietnam as example. In this area, “One Commune, Product” (OCOP) project has been implemented by government. study employs randomized conjoint analysis based data collected from 450 randomly selected several supermarkets. Interestingly, results show online style sales have a negative preference purchase products, while transparency, such traceability product information, reliability, certification, enhance these consumers. However, finding necessarily robust because our indicate approximately 90% tend to choose default pair, means they do actively prefer product, possibly implying kind yet broadly familiar all people.

Long-term mulched drip irrigation facilitates soil organic carbon stabilization and the dominance of microbial stochastic assembly processes

Agricultural Water Management, Год журнала: 2024, Номер 302, С. 109008 - 109008

Mulched drip irrigation (MDI) is generally accepted as a method to decrease soil salinization and improve crop yields in arid semi-arid regions. However, there remain gaps how MDI drives organic carbon (SOC) dynamic microbial assembly processes with time, the mediating role of microorganisms remains unclear. In this study, we investigated aforementioned issues across profiles cotton fields different years MDI. The results showed that did not cause differences SOC, particular (POC), mineral-associated (MOC) layers. POC MOC contents had parabola relationship an opposite trend soil. After 15 MDI, ratio MOC/SOC increased peak value 50 % 52 topsoil subsoil, respectively; POC/SOC decreased valley values 48 %, respectively (P < 0.05). Long-term reduced oxidase between layers but accelerated SOC loss by increasing polyphenol activity Compared other years, 10 bacterial Shannon diversity value, fungal reached top subsoil general, stochastic were mainly controlled dispersal limitation, undominated dominated assembly; however, was close communities fractions. high percentage positive linkages among indicated long-term beneficial for fixation. Additionally, oligotroph/copiotroph ratio, relative abundance Ascomycota Basidiomycota accumulation conclusion, useful fixation via improving content strengthening within community assemblies.
