Accordingly, the study evaluated the influence of oil palm cultivation on soil quality in a coastal plain sands area of Akwa Ibom State, Nigeria. Four oil palm blocks of varying ages: 57 years (B-57), 39 years (B-39), 17 years (B-17) and a no oil palm block (B-0), which served as the control was used for the study. A total of 12 pits were dug. The soils were described according to horizon designation as observed in the soil profile, sampled at both dry and wet seasons, air dried, sieved and taken to the laboratory for analysis. The data obtained were subjected to laboratory analysis. The soil quality evaluation using principal component analysis method, showed that oil palm improved the soil quality in the dry season with the best quality in B-17 (2.34) followed by B-57 (2.14), B-0 (2.0) and B-39 (1.85). After initial improvement in soil quality by oil palm plantation, up to 17 years of age, the soil quality degraded as the oil palm advanced in age up to 39 years, before it improved again such that soil quality was better at 57 years than when it was assessed at 39 years. Irrespective of the age of oil palm plantation, soil quality was degraded by the wet season. The trend (for wet season) was as follows: B-39 ><em>B</em>-17 ><em>B</em>-57= B<em>-</em>0. The study has revealed that oil palm cultivation can serve as a good soil management and conservation practice in the coastal plain sands area, since it has the potential of improving soil quality (physical, chemical and biological) the longer it stays on the soil.</p></div>","PeriodicalId":74839,"journal":{"name":"Soil security","volume":"10 ","pages":"Article 100087"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44698384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These challenges have been previously addressed by a myriad of concepts such as soil conservation, soil quality, and soil health. Yet, of these, only soil security attempts to integrate the six existential challenges concurrently through the five biophysical and socio-economic dimensions of capacity, condition, capital, connectivity and codification. In this paper, we highlight past and existing concepts, and make a proposal for a provisional assessment of soil security. The proposal addresses three roles of soil: soil functions, soil services and threats to soil. For each identified role, we indicate a potential, but not exhaustive, list of indicators that characterise the five dimensions of soil security. We also raise issues of quantification and combination of indicators briefly. We found that capacity and condition are theoretically easier to measure and quantify than connectivity and codification. The dimension capital might be conveniently assessed using indicators that relate to the economic value of soils. The next step is to test this proposal for which we make recommendations on potential study cases and examples. We conclude that the five dimensions of soil security can potentially be assessed quantitatively and comprehensively using indicators that characterise each role, but also found that there is need for further work to devise an operational measurement methodology to estimate connectivity of people to soil.</p></div>","PeriodicalId":74839,"journal":{"name":"Soil security","volume":"10 ","pages":"Article 100086"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49753684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Non-expert participation in soil research and management is diverse and applied variously, ranging from data collection to inform large-scale monitoring schemes in citizen science projects to projects in which the participants define the object of study and the questions to be answered. The growth of participatory projects to tackle complex environmental and soil-related issues has generated literature that describes both the way the projects are initiated, implemented and the outcomes they achieve. We review the existing literature on participatory soil research and management. Existing studies are classified into three categories based on the degree of participation in the different phases of research. The quality of participation is further evaluated systematically through the five elements that participatory projects usually include: inputs, activities, outputs, outcomes and impacts. We found that the majority of existing participatory projects were contributory in nature, where participants contribute to generating data. Co-created projects which involve a greater level of participation are less frequent. We also found large disparities in the context in which these types of participation occurred: contributory projects were mostly documented in more economically developed countries, whereas projects that suggest greater involvement of participants were mostly formulated in developing countries in relation to soil management and conservation issues. The long-term sustained outcomes of participatory projects on human well-being and socio-ecological systems are seldom reported. We conclude that participatory approaches are opportunities for education, communication and scientific progress and that participation is being facilitated by digital convergence. Participatory projects should, however, also be evaluated in terms of their long-term impact on the participants, to be sure that the expectations of the various parties align with the outcomes. All in all, such participation adds to the quantum of soil connectivity and in this sense makes the soil more secure globally.</p></div>","PeriodicalId":74839,"journal":{"name":"Soil security","volume":"10 ","pages":"Article 100085"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49753941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To test the extent of their agreement, Land Capability Classification (LCC), Fertility Capability Classification (FCC), and Suitability Rating were combined in physically evaluating soils of Coastal plains sand, Imo State, Nigeria, using data from 20 pedons. With respect to LCC, soils of inland valleys were limited mainly by wetness, which had 2 out of 6 profiles of the unit classified beyond the arable. The well-drained upland soils, all of which fell within the arable classes, were subject to sheet and rill erosion. By standards of FCC, soils were limited by ‘g’ - water logging; e - low ability to retain nutrients; i - potential fe - toxicity; k - low nutrient capital reserves. Based on suitability rating, soils potentials for agriculture varied from poor to good. Results of LCC and FCC correlated significantly (r = 0.771), but none of these correlated with suitability ratings of the soils. Use of the international systems should be augmented with further soil tests some of which may be got from other comparable systems so as to capture other locally important environmental details. Subjecting factors identified by FCC to suitability rating improved evaluation procedure. Land use in the location did not strictly consider the capability of the land.

With this interest, there is growing need to verify and monitor changes in soil health that result from how agricultural soil is managed. There are many indicators of soil health and, although this benefits the scientific community, it complicates interpretation across studies. The North American Project to Evaluate Soil Health Measurements (NAPESHM) assessed over 30 available measurements on 124 long-term agricultural research sites with replicated soil health treatments and created new pedotransfer functions. This analysis draws on findings from NAPESHM to identify a minimum suite of effective indicators of soil health for the North American Continent. The criteria for a minimum suite of effective indicators are that they (1) primarily reflect soil health rather than inherent soil properties or fertility, (2) are responsive to agricultural management practices that exemplify soil health principles, (3) are conducive to measuring soil health at scale in terms of cost and availability, and (4) are not redundant with regard to linking different soil functions to ecosystem services. Many indicators were determined effective for use in soil health studies and based on this analysis, soil organic C concentration, aggregate stability, and 24 h C mineralization potential were selected for the minimum suite of indicators. Using this minimum suite, as few as three laboratory measurements can be made to assess and track improvement in soil functioning as a result of soil management changes. These indicators may be supplemented with new pedotransfer functions to also estimate changes in available water holding capacity. This minimal suite of soil health measurements is recommended for scaling up soil health assessments across North America, and possibly beyond.</p></div>","PeriodicalId":74839,"journal":{"name":"Soil security","volume":"10 ","pages":"Article 100084"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49754153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Following these criteria, we present three strands of research on soil-related issues: (1) Literature bearing on the politics of soil knowledge investigates how soil becomes an object of knowledge and management; (2) Soil new materialism addresses practices and ethics of caring for the living soil; (3) Soil decolonial studies unravel soils’ powers and the intertwined agencies of soils and societies. By examining these research agendas, we suggest that social and human thinkers have, in the past two decades, tended to shift from a focus on the socially constructed nature of soils, to a growing emphasis on soils’ own biophysical agency in shaping societies, also in line with soil sciences insights and works. We argue that the increasing uptake of soil in human and social sciences contributes to an increasing concern for achieving better theoretical and empirical accounts of the co-constitution of society and the material world.</p></div>","PeriodicalId":74839,"journal":{"name":"Soil security","volume":"10 ","pages":"Article 100082"},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41342958","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
