Soil dataset from poplar cultivation sites in northern Italy plains
<p>The soil sampling activities conducted in the plains of northern Italy adhered to the methodology outlined in the poplar inventory dataset by Rizza et al. (2023). The dataset consisted of 2,322 clusters that were georeferenced on a three-kilometre UTM grid, systematically distributed across an area spanning 4,179,600 hectares. Each cluster comprised nine subunits aligned with the points on a 500-meter square grid. </p> <p>The soil sampling took place between 1994 and 1996 and focused on locations with poplar plantations that were at least five years old in 1994. To obtain the samples, a pedological profile was manually excavated, and each layer was identified. One kilogram of soil was collected from each layer.</p> <p>Each soil sample was labelled with the region's sampling letter, cluster number, and element number. A maximum of five depths were examined for each sample. The texture characteristics (fine sand, coarse sand, fine silt, coarse silt, and clay) and certain chemical properties (limited to the first horizon) were documented, including NH4+, NO3-, CaCO3, P2O5, pH, organic matter, and soil carbon. </p> <p>Moreover, the presence of irrigation was recorded, and for the first layer, the depth of the temporary and permanent water table was reported. It is important to note that for certain samples, only the surface soil layers were evaluated, omitting depths exceeding 60 centimetres.</p> <p>Additionally, the soil samples were air dried, sieved to two millimetres and then scanned using an ASD Fieldspec instrument, particularly the LabSpec Pro Spectrophotometer LSP 350-2500P Analytical Spectral Devices, Inc. The reflectance at wavelength range 350–2500 nm was acquired with an interval of 1 nm. The resulting Vis-Nir soil spectral library was integrated with the soil data and entered in two excel worksheets joined by a sampleID.</p> <p>The coordinates of the samples are in WGS 84 - EPSG 4326.</p>
SDM current and future projections for alternate CAM-based cultivation in SSA
<p class="MsoNormal">Globally we are facing an emerging climate crisis, with impacts to be notably felt in semi-arid regions across the world. Cultivation of drought-adapted succulent plants has been suggested as a nature-based solution that could: (i) reduce land degradation, (ii) increase agricultural diversification and provide both economic and environmentally sustainable income through derived bioproducts and bioenergy, (iii) help mitigate atmospheric CO<sub>2</sub> emissions, and (iv) increase soil sequestration of CO<sub>2</sub>. Identifying where succulents can grow and thrive is an important pre-requisite for the advent of a sustainable alternative 'bio-economy'. Here we first explore the viability of succulent cultivation in Africa under future climate projections to 2100 using species distribution modelling to identify climatic parameters of greatest importance and regions of environmental suitability. Minimum temperatures and temperature variability are shown to be key controls in defining the theoretical distribution of three succulent species explored, and <span>under both current and future SSP5 8.5 projections, the conditions required for growth of at least one of the species is met in most parts of sub-Saharan Africa. </span>These results are supplemented with an analysis of potentially <em>available</em> land for alternative succulent crop cultivation. <span>In total</span>, <span>up to 1.5 billion hectares could be considered ecophysiologically suitable and available for succulent cultivation due to projected declines in rangeland biomass and yields of traditional crops. These </span>findings may serve to highlight new opportunities for farmers, governments, and key stakeholders in the agriculture and energy sectors to invest in sustainable bioeconomic alternatives that deliver on environmental, social and economic goals.<span> </span></p>
Effect of climate-change-induced increases on the range of rice-barley double cultivation on the intermediate egret
<p><span>Intensification of cultivation methods and land use types, particularly in the face of climate change, has steadily weakened the habitat function of rice fields for waterbirds.</span></p> <p><span>Intermediate egrets (<em>Ardea intermedia</em>) are highly dependent on rice field habitats. Here, we examine the effect of a shift from rice monoculture to rice–barley double cultivation on the use of rice fields by intermediate egrets in South Korea. Rice</span><span>-</span><span>barley double cultivation has been increasing steadily in the southern region of South Korea due to changes in the rice growth period under climate change and maximization of economic benefits.</span></p> <p><span>We studied rice fields to determine the effect of the rice-barely double cultivation area on the abundance of intermediate egrets on the regional scale and their potential distribution pattern in response to double cultivation in relation to climate change using national-scale climate, altitude, and land cover data from May 1 to June 23, 2018.</span></p> <p><span>Compared to the irrigation practices used for rice monoculture, irrigation was stopped for some time in rice-barley double cultivation prior to planting, compromising the role of rice fields as a food ground for intermediate egrets. The potential abundance of intermediate egrets rapidly decreased by half when the double cultivation area increased to >40% of the total rice-field area, and was less than one individual if the area increased to >80%. Furthermore, according to climate change projections, by 2100, the double cultivation area would account for 75.74% of the predicted range of intermediate egret foraging ground.</span></p> <p><em><strong><span>Synthesis and applications.</span></strong></em><span> Double cultivation areas should be <40% of existing rice fields to minimize the impact of the change in cultivation practices. This approach can also convert rice fields to other types of land use. Consequently, appropriate conservation and management measures may be developed to maintain suitable habitats despite rapidly changing cultivation practices resulting from climate change.</span></p>
Data for: Potential of root acid phosphatase activity to reduce phosphorus fertilization in maize cultivated in Brazil
<p><strong>Potential of root acid phosphatase activity to reduce phosphorus fertilization in maize cultivated in Brazil</strong></p> <p class="Texto"><span>It is urgent to mitigate the environmental impacts resulting from agriculture, especially in highly biodiverse and threatened areas, as the Brazilian Cerrado. We aim to investigate whether root acid phosphatase activity is an alternative plant strategy for nutrient acquisition in maize genotypes cultivated under fertilized and unfertilized conditions in Brazil, potentially contributing to reducing the use of phosphate fertilizers needed for production. Three experiments were performed: the first was conducted in a glasshouse, with 17 experimental maize inbred lines and two phosphorus (P) treatments; the second in the field, with three maize inbred lines and two treatments, one without fertilization and another with NPK fertilization; and the third was also carried out in the field, with 13 commercial hybrids, grown either under NK or under NPK treatment. Plant variables were measured and tested for the response to fertilization, differences amongst genotypes and response to root acid phosphatase activity. The activity of root acid phosphatase was modulated by the availability of P and nitrogen (N) in the soil and promoted grain filling of commercial hybrids in soils with low P availability. These results demonstrate that it is possible to select genotypes that are more adapted to low soil P availability aiming at organic production or to use genotypes that have high phosphatase activity under P fertilization to reduce the amount of added P needed for maize production in Brazil. </span></p>
