SR24012Spatial variability of soil carbon across a hillslope restoration planting in New Zealand

Molly Katharine D’Ath, Katarzyna Sila-Nowicka and Luitgard Schwendenmann

 

As part of global efforts to restore forests and combat climate change, our study investigates young forest restoration plantings in northern New Zealand. Spatial variation in soil, vegetation, and carbon storage across a small hillslope area showed that several topographical, soil- and vegetation-related characteristics significantly influenced soil carbon stocks. This discovery underscores the crucial role of landscape characteristics in shaping the success of forest restoration initiatives, emphasising the need for thoughtful planning that incorporates the unique features of each terrain.

SR22257Impact of green manure crop species on rhizosphere soil phosphorus

P. V. Nguyen , R. W. McDowell and L. M. Condron

 

Enhancing the mobilisation of soil legacy phosphorus to increase phosphorus use efficiency in agroecosystems may be very important, while phosphorus reserves will be depleted within 100 years. The studied green manures have rapidly mobilised different soil phosphorus pools. Therefore, the green manures may convert less labile soil phosphorus into more labile forms for the main crops, leading to a reduction of phosphorus inputs.

SR24034Organic carbon and short-range order minerals responsible for cementation of the spodic horizon (ortstein): a new proposal of chemical extractions in undisturbed samples

Mateus Roveda Pilar, Vander Freitas Melo , Luis Fernando Roveda, Marcelo Ricardo Lima and Jairo Calderari de Oliveira Junior

 

Oststein in Spodosols limits the drainage of these sandy soils (normally sand content >95%) and increases nutrient retention in the profile, increasing plant production. We used more reliable undisturbed samples of ortstein horizon and a new chemical extraction protocol, differing from the use of powdered samples in the literature. The destruction of soil structure in disturbed samples results in the loss of mineral and organic phase that could be clogging the sample pores. We believe that our work encourages worldwide orststein horizon studies.

We evaluated the influence of intercropping maize with forage grasses of the genus Megathyrsus and Urochloa on soil properties and on yield of succeeding soybean (Glycine max) in the Cerrado of north-east Brazil. Intercropping maize with forage grasses of the genus Urochloa increased soil humic substances and carbon concentrations, whereas intercropping maize with species of the genus Megathyrsus improved the soil chemical and biological attributes. Average soybean yield was 15% higher when cultivated following maize + forage grasses, compared to monoculture maize.

SR23257Functional annotation of paclobutrazol-treated mango rhizospheric soil reveals the recruitment of plant growth-promoting and xenobiotic compound-degrading bacterial species

V. K. Singh , Sumit K. Soni , Pradeep K. Shukla and Anju Bajpai

 

Mango cultivation is a profitable proposition for growers. However, mango yields vary considerably, with years of optimum or heavy fruiting (‘on year’) followed by little or no fruiting (‘off year’). Application of paclobutrazol (PBZ) is often used to address this alternate bearing problem. However, PBZ has a detrimental effect on soil health by impacting the microbial community and related functions. This study examines the impact of PBZ on soil microorganisms using a high-throughput sequencing technique.

SR22252Organic amendments improved soil properties and native plants’ performance in an Australian degraded land

Jonas Larsen, Mehran Rezaei Rashti , Maryam Esfandbod and Chengrong Chen

 

Land degradation has impacted the environment significantly, where soil fertility, food production, water, and an array of ecosystem services have been compromised. Research in this paper investigates the potential for compost and biochar amendments to improve native plant growth in land remediation, for which most benefits were revealed from a mixture of compost and biochar. Land remediation projects may wish to utilise the unique benefits of a compost-biochar mixture in establishing plants used in this study.

SR23133Alpine meadow degradation decreases soil P availability by altering phoD-harbouring bacterial diversity

Yanuo Zou, Xiangtao Wang, Jie Wang, Lu Zhang, Lirong Liao, Guobin Liu, Zilin Song and Chao Zhang

 

Understanding how the phosphorus (P) availability changes with meadow degradation is essential for the restoration of the alpine ecosystem. We investigated the phoD-harbouring bacterial community in four alpine meadows along a degradation gradient on the Tibetan Plateau and found alpine meadow degradation decreases soil P availability by regulating phoD-harbouring bacterial community diversity and alkaline phosphates, with soil water supply and plant biomass being the main driving factors. This study revealed the mechanisms of decreased P availability during alpine meadow degradation.

SR23253Determining the depth and rate of soil movement down the soil profile using an environmental tracer: a hillslope scale assessment

G. R. Hancock , A. Gibson, I. P. Senanayake and Tristan Cox

 

Soil materials can be delivered to depth from both in situ and ex situ materials. Results demonstrate that soil material from the surface can reach depths of up to 80 cm near the hillslope crest and 2.2 m at the base of the hillslope and a relatively rapid (decadal time scale) translocation.

SR23205Physical properties and organic carbon in no-tilled agricultural systems in silty Pampas soils of Argentina

Guillermo Ezequiel Peralta , Rodolfo Cesáreo Gil, María Belén Agosti, Carina Rosa Álvarez and Miguel Ángel Taboada

 

In the Argentine Pampas, continuous no-till farming has led to deterioration in soil structure, affecting crop yields. We investigated production situations with different cropping intensification to improve soil health. While increased cropping intensity resulted in higher carbon inputs, improvements in soil physical properties were absent. It is important to design management strategies that not only allow for increased yields but also improve the physical quality of the soil.

SR23192Polymer-coated urea applied at one-time mechanical topdressing increases nitrogen use efficiency and rice yield in the cold area

Cailian Yu , Yuchen Lin , Bolin Li, Xiaolun Liu, Zhilei Liu and Xianlong Peng

 

Urea applied to agricultural fields volatilises as ammonia, which results in huge wastage. This study showed that polymer-coated urea can reduce ammonia volatilisation from urea, lower the pH of paddy water, improve urea utilisation, and ultimately increase rice yield. This helps to reduce labour as well as environmental pollution from over-application of fertilisers.

SR23174Soil aluminum saturation threshold for subtropical crops in no-tillage system

Danilo dos Santos Rheinheimer , Alexandre Troian , Marília Camotti Bastos , Gustavo Pesini and Tales Tiecher

 

Agricultural production models in subtropical regions should involve the use of Al-tolerant plant varieties that respond well to the application of lime. We have been monitoring soil reacidification and its impact on crop yields for more than 3 decades following the conversion from conventional to no-tillage cultivation. The tolerance of the varieties to Al³⁺ made it possible to obtain high and stable yields only with superficial reapplications of lime, because the natural potential acidity had been amended when adopting no-tillage.

SR23061Chemical and mineralogical factors affecting the kinetics of acid drainage in different geomaterials

Walter A. P. Abrahão, Isabela C. F. Vasques , José D. Fabris and Jaime W. V. de Mello

 

The environmental impacts that the use of sulfides containing soils can cause are worrisome, being the acid drainage (AD) one of them. This problem has some chemical aspects that are not well understood, such as the rate of AD production. This study shows that the size and structure of the mineral that promotes acid drainage (sulfides) are the main aspects of this process.

SR24009Evaluating effects of physical soil and water conservation measures using farmers’ perception and soil analysis in southern Ethiopia

Habtamu Ermias, Kebede Wolka and Birhanu Biazin

 

Evidence on the effects of soil and water conservation (SWC) measures is inadequate. Examining the effects of variously aged SWC measures is important. Laboratory analysis of 59 soil samples and the opinion of 122 farmers were used in this study. Approximately 40% of respondents perceived severe soil erosion, and 96% of the farmers were interested in repairing it. The soil organic carbon, total nitrogen, and available phosphorous were significantly greater in the fields with older soil bunds. Farmers are advised to retain bunds.

SR23160Vertical distribution of edaphic oribatid mites (Acari: Oribatida) in two artificial forests planted on temperate grasslands

Eugenia Levy , M. Fernanda Alvarez and Natalia A. Fredes

 

Oribatids are the most abundant mites in the soil fauna of woodlands, where they inhabit spaces between soil particles. We studied their distribution in artificial woodlands of Eucalyptus and Pinus trees planted in soils that were originally grasslands, and found that they depend on the 3D configuration of litter layers determined by the availability of the organic remains present. This information has applications on the assessment and management of woodlands, being relevant for better assessment of soils diversity.

SR23248Comparison of laser-induced breakdown spectroscopy (LIBS) and ICP analysis results for measuring Pb and Zn in soil

Hyeon Yang , Young-Tae Jo , Jihyo Chong , Yonggwan Won and Jeong-Hun Park

 

Laser-induced breakdown spectroscopy (LIBS) is a rapid, multielement analytical technique, suitable for the qualitative and quantitative analyses of heavy metals in soil. The LIBS data were compared with the data obtained via conventional inductively coupled plasma (ICP) spectroscopy to validate the technique. The concentration coefficient of determination between LIBS and ICP analysis were >0.86 and >0.89 for Pb and Zn, respectively. The total analysis time for the LIBS method was 310 min, which was 54.40% shorter than that for the ICP method.
