The aim of this study was to assess soil C sequestration in representative tropical (Caribbean) MCLS in the Guadeloupe Archipelago. We designed a modeling approach at the scale of the farm and cropping system, based on a data-driven model of soil organic C (SOC) balance coupled to three databases. The variables included soil properties, manure properties (fresh and stored-composted), and farm characteristics of the eight MCLS. The results indicated that land use (i.e., relative area occupied by perennial crops) was the main factor controlling soil C sequestration at the farm scale and that pasture and sugarcane systems were crucial for maintaining or increasing SOC stocks. Under the current MCLS management, only 16 % of manure production is used to fertilize croplands. This mode of fertilization was found to be ineffective at the farm scale, given that it resulted in low (average + 0.03 % yr⁻¹) or negative (up to −0.3 % yr⁻¹) soil C sequestration; manure C inputs did not compensate for SOC outputs by mineralization in annual systems. It is estimated that increasing manure use to near 100 % would increase the level of soil C sequestration 3.5-fold (average + 0.11 % yr⁻¹) and could compensate for up to 20 % of the reduction in C inputs from crop residues used as animal feed. These effects were 50 % higher for fresh manure than for stored-composted manure because of mass and C losses during storage, which reduced the level of manure C inputs to the soil. Overall, the results indicate that increasing manure use and shortening the storage period through, for example, more frequent split applications would be suitable to boost soil C sequestration and sustainability in tropical MCLS by decreasing soil C losses and increasing C retention in soil. However, trade-offs must be made between managing the frequency of applications, the cost and degree of manual labor required, and optimizing the overall health of the MCLS.</div></div>","PeriodicalId":56001,"journal":{"name":"Geoderma Regional","volume":"41 ","pages":"Article e00968"},"PeriodicalIF":3.1,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144131135","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, we investigated a toposequence of buried soils near the Serra do Brigadeiro – Minas Gerais State, aiming to comprehend the environmental conditions under which these soils were formed. To this end, we described, classified and analyzed eight pedocomplexes constituted of buried and overlying soils, focusing on their chemical, physical and mineralogical attributes.

We also dated the Ab horizons using Optically Stimulated Luminescence, aiming to obtain the timing of soil burial. Soils were, in general, acidic, clayey to very clayey, nutrient-poor, and with mineralogy dominated by kaolinite, gibbsite and goethite, typical of tropical soils. Past soils, found in the lower slopes, were buried by colluvial deposits derived from mass movements, mainly triggered during the Mid-Holocene (7500 to 5000 yr BP), possibly under dry and seasonal climates. The slope colluvium consists of highly pedogenized material with a degree of weathering similar to that of the buried soils, which justifies the absence of lithological discontinuities. The δ¹³C signal, indicating a mixture of C3 and C4 plants, suggests that the colluvial processes were intensified by the presence of more open vegetation, presumably a wooded savanna. The abundant presence of charcoal suggests the frequent occurrence of paleofires, either climate-induced or anthropogenic.</div></div>","PeriodicalId":56001,"journal":{"name":"Geoderma Regional","volume":"41 ","pages":"Article e00967"},"PeriodicalIF":3.1,"publicationDate":"2025-05-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144114853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Assessing and identifying saline land as having advantages for improvement is of great significance for improving the efficiency of saline croplands improvement. Taking the western Songnen Plain as the study area, an evaluation framework for identifying saline-alkali croplands for improvement was proposed. Compared with traditional research models that evaluate the degree of saline-alkali land suitable for farming, the purpose of this study is to identify land that is easier to improve and has more or more value for farming. On the basis of evaluating the suitability of saline-alkali land using the Analytic Hierarchy Process-Geographic Information System (AHP-GIS) model, this framework incorporates the degree of soil salinisation, quantified by electrical conductivity and exchangeable sodium percentage, and hydrological connectivity, calculated based on terrain factors and vegetation cover., constructs a saline-alkali land improvement index, and divides suitable improvement areas at different levels. The results indicate that the northern part of the study area exhibits low cropland suitability value, primarily due to higher pH values, unfavorable topography, and lower temperatures. Extreme salinity area are concentrated in the central part of the study area, mainly due to elevated soil conductivity and exchangeable sodium percentages. Areas with high hydrological connectivity value are distributed in the northern, southern, and eastern parts, owing to the presence of numerous lakes and dense vegetation cover. Using the Suitable Improvement Index (SII), 39.42 % of the croplands were identified as suitable for improvement. Among these, low-value, moderate-value, and high-value accounted for approximately 5.43 %, 33.36 %, and 61.21 % of SII subareas. The low SII values are found in Qianan and Tongyu in the southern and central parts of the study area, while high SII values are distributed in Tongyu, Daan, and Taobei in the central part of the study area.

Fertiliser advice is generally accessible via blanket recommendations at a national scale. Hence, an alternative approach is needed to estimate soil nutrient content across the diverse landscapes of Ethiopia. In this study, we propose using diagnostic features to estimate soil nutrient content, which could contribute to the development of fertiliser recommendations. To achieve this the following objectives were defined: (i) to estimate soil nutrient content as influenced by soil diagnostic features; and (ii) to elucidate the influence of environmental covariates and diagnostic features on the estimation of soil nutrient levels in the Ethiopian context. Data from 550 soil profiles, distributed across Ethiopia, were collected from a range of published sources, collated and harmonised. The data were cleaned, and 496 soil profiles were prepared for modelling. To identify which diagnostic characteristics were present across these soils we applied a presence/absence scoring method to identify dominant diagnostic features. Multiple linear regression analyses were used to predict soil chemical properties from the diagnostic features and diagnostic features along with environmental covariates. The performance of the models was evaluated by applying a 10-fold cross-validation using mean error (ME), Lin's concordance correlation coefficient (LCCC), root mean square error (RMSE) and model efficiency coefficient (MEC). The MEC values for pH, TN, and CEC derived from a combination of diagnostic features and environmental covariates were 0.38, 0.33, and 0.38. The corresponding RMSE values were 0.78, 0.07 %, and 13 cmol kg⁻¹. Additionally, the LCCC values for pH, TN, and CEC were 0.62, 0.58, and 0.62, respectively. The cross-validation results for soil chemical properties showed that the model's performance improved when environmental covariates were added. Precipitation, temperature, geology and land cover were the most important environmental covariates for estimating nutrient content, along with diagnostic features of Ethiopian soils. In conclusion, the diagnostic approach offers a useful starting point for estimating soil nutrient content. However, the variation in nutrient content across the six diagnostic features was not adequately quantified, and the model's predictive performance remains insufficient for practical application at the local scale. Further expansion of the dataset is required to fully exploit the potential of these models for underpinning nutrient management decisions across Ethiopia and in other regions where access to soil test information is limited.</div></div>","PeriodicalId":56001,"journal":{"name":"Geoderma Regional","volume":"41 ","pages":"Article e00962"},"PeriodicalIF":3.1,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143891769","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
