Maintaining good soil quality is crucial for the sustainability of agriculture. This study aimed to evaluate the effectiveness of the visual soil assessment (VSA) method by testing it on two soil types and two agricultural management practices (AMP) (organic and integrated) that are considered to protect soil quality. We selected two farms with plots on two river terraces with different soil properties. The test was based on the modified method Annual Crops Visual Quality Assessment developed by the Food and Agriculture Organization of the United Nations and supported by a standardized soil physical and chemical analysis. This study showed that the assessed score is highly dependent on the type of farming practice and how soils are managed. The soil type also plays an important role. The results for Calcaric Fluvisol showed that the effects of selected agricultural management practices on the visual assessment of soil quality could be almost undetectable. The time of assessment also plays a significant role in VSA scoring. Different crops and agricultural activities with significant impacts on the soil occur throughout the year (especially in vegetable production). It was observed that a higher score for the soil cover indicator had a beneficial effect on the total VSA rating.

Abstract Background The soil quality and health of the tea plantations are dependent on the agriculture management practices, and long-term chemical fertilizer use is implicated in soil decline. Hence, several sustainable practices are used to improve and maintain the soil quality. Here, in this study, changes in soil properties, enzymatic activity, and dysbiosis in bacterial community composition were compared using three agricultural management practices, namely conventional (CA), sustainable (SA) and transformational agriculture (TA) in the tea plantation during 2016 and 2017 period. Soil samples at two-months intervals were collected and analyzed. Results The results of the enzyme activities revealed that acid phosphatase, arylsulfatase, β-glucosidase, and urease activities differed considerably among the soils representing the three management practices. Combining the redundancy and multiple regression analysis, the change in the arylsulfatase activity was explained by soil pH as a significant predictor in the SA soils. The soil bacterial community was predominated by the phyla Proteobacteria, Acidobacteria, Actinobacteria, Chloroflexi, and Bacteroidetes in the soil throughout the sampling period. Higher Alpha diversity scores indicated increased bacterial abundance and diversity in the SA soils. A significant relationship between bacterial richness indices (SOBS, Chao and ACE) and soil pH, K and P was observed in the SA soils. The diversity indices namely Shannon and Simpson also showed variations, suggesting the shift in the diversity of less abundant and more common species. Furthermore, the agricultural management practices, soil pH fluctuation and the extractable elements had a greater influence on bacterial structure than that of temporal change. Conclusions Based on the cross-over analysis of bacterial composition, enzymatic activity and the soil properties, the relationship between bacterial composition and biologically-driven ecological processes can identified as indicators of sustainability for the tea plantation.

<p>Potential changes in soil quality as result of intensive agriculture are increasingly raising concerns about associated impacts and the need to implement more sustainable agricultural practices. Among several intensive crops, maize, an important human food source, is one of the most intensely produced around the world, representing harmful consequences for soil quality. Therefore, it is fundamental to understand how different agricultural management practices can influence soil quality. Hence, the main objective of this study was to compare the implications of the conventional tillage versus non-tillage in soil quality. Additionally, it was also an objective to evaluate how the implementation of herbage strips, non-irrigated and fallow areas, contribute to soil sustainability and biodiversity preservation, compensating the impacts of intensive maize cultivation. For this purpose, an integrative approach was adopted including physical-chemical parameters (e.g. bulk density, pH, electrical conductivity, field capacity, organic matter, nutrients) and biological parameters (e.g. phosphatase activity, urease activity, ecotoxicological tests with soil organisms).</p><p>The obtained results revealed the existence of differences between the analyzed practices, mainly associated with chemical parameters and nutrients. When comparing no-till and conventional sowing, higher mean values for no-till were observed for the following parameters: organic matter, cation exchange capacity, nitrogen, phosphorus, nitrates, calcium, copper, zinc, iron, manganese, urease activity and invertase activity. Hence, this study highlights the importance of the implementation of nonconventional agricultural practices, as is the case of no-till, as promoters of productivity and soil sustainability. Additionally, different management practices as herbage strip, non-irrigated and fallow areas around conventional areas play an additional role in soil quality and biodiversity preservation.</p>

Policy Scenarios

<p>Aiming to evaluate the effect of agricultural management practices in the environmental footprint, this study develops scenarios of future farm and soil management systems for improved productivity and enhanced soil quality. The analysis is at the continental scale in Europe and China. The evaluation has two components: (1) A multi-actor approach is used to develop the policy scenarios; and (2) An upscalling model is used to evaluate the effect of the scenarios at the continental scale. The results are presented in a series of maps with a 10 x 10 km resolutions, that allow comparison of strategies relevant to agricultural policy development. Three scenarios are evaluated: The Expected scenario maintains the observed tendency in the implementation of beneficial agricultural management practices. The Regional Targets assumes the same rate of implementation of agricultural management practices, but considers that policy efforts are focused on areas where soil threats are more active and soil quality indicators are poorer. The emphasis, therefore, is place on targeting the regions that where the practices would be more beneficial. The Towards 2050 scenario assumes an intensification on the rate of implementation of agricultural management practices as a result of public policies. The scenarios are necessarily a simplification of the complex policy processes that influences farmer choices at the local and regional levels. The content of the study is based on the results of the iSQAPER (http://www.isqaper-project.eu/) H2020 project.</p>
