Responses of soil organic carbon to conservation practices including climate-smart agriculture in tropical and subtropical regions: A meta-analysis

Response of nitrate leaching to no‐tillage is dependent on soil, climate, and management factors: A global meta‐analysis

“…Although NT adoption in higher SOC soils is more likely to reduce the NO 3 − leaching risk, it remains unclear if the reduced NO 3 − leaching risk under long-term NT is attributable to an increase in SOC content (Kan et al, 2021). The inconsistent effects of NT duration on the relative changes in SOC under NT compared to tilled soils reported in previous meta-analyses (Das et al, 2022;Kan et al, 2021;Li et al, 2020;Nunes et al, 2020;Peixoto et al, 2020), and the poor correlation between NT duration and SOC in the current study (Figure S5), suggest that the influence of NT duration on the NO 3 − leaching risk may not be associated with changes in SOC content. Greater soil water content under NT relative to that under tillage was more prevalent in drier climates (De Vita et al, 2007).…”

Meta-analysis of global soil data identifies robust indicators for short-term changes in soil organic carbon stock following land use change

“…Studies that compared conventional tillage/agriculture (as control) with minimum/no tillage or other forms of conservation agriculture such as the use of cover crops and organic manure were not included in this study because there are many recent review articles (e.g., Liu et al, 2021;Topa et al, 2021;Bohoussou et al, 2022;Das et al, 2022;He et al, 2022) that addressed the impacts of such agricultural land management changes on soils. Hence, the arable control used in this study refers to cultivated lands under crop production regardless of the intensity of tillage and the presence of conservation practices.…”

Agricultural Greenhouse Crop Information System based on Big Data and Cloud Computing Technology

“…The shading net can control the intensity and duration of light and can adjust the intensity and duration of care according to the different growth stages of different crops. It can effectively ensure the healthy growth of crops, and can prolong the growth period of crops to achieve the effect of increasing production; after reading the temperature and humidity in the greenhouse, set the most suitable humidity according to the different requirements of different crops and soil moisture, and complete Automatic irrigation reduces manual labor and waste of water resources; greenhouse lighting is closely related to crop growth [4]. Capturing light energy to the maximum extent and giving full play to the potential of plant photosynthesis will be directly related to the benefits of agricultural production.…”
