Abstract Soil microbial communities directly affect soil functionality through their roles in the cycling of nutrients and carbon storage. Microbial vary substantially space time, between types under different land management. The mechanisms that control spatial distributions microbes are largely unknown as we have not been able to adequately upscale a detailed analysis microbiome few grams catchment, region or continent. Here reveal along 1000 km transect unique structures governed mainly...

Abstract. Soil aggregate stability is a useful indicator of soil physical health and can be used to monitor condition through time. A novel method quantifying stability, based on the relative increase in footprint area aggregates as they disintegrate when immersed water, has been developed performed using smartphone application – SLAKES. In this study SLAKES was obtain slaking index (SI) values topsoil samples (0 10 cm) at 158 sites assess mixed agricultural landscape. large range SI 0 7.3...

A fifty-four per cent of the global population is estimated to live disconnected from natural environment. Furthermore, a large majority our community unknown how significant soil in their life, e.g. provider food, energy and medicine, etc. Strengthening this connection one relevant action toward Soil Security, referred as "Soil Connectivity". Citizen Science (CS) improves connectivity by increasing citizens awareness making them collect scientific data. Unfortunately, an indicator increases...

Abstract Microorganisms play pivotal roles in soil processes. Metabolically related microorganisms constitute functional groups, and diverse microbial groups control nutrient cycling soils. This study explored environmental (i.e., rainfall, temperature) factors driving the distribution of bacterial involved carbon (C) paired natural agricultural ecosystems. Soil samples were collected at a regional scale covering gradients temperature rainfall across two orthogonal transects (~1000 km) New...

Declines in soil multifunctionality (e.gsoil capacity to provide food and energy) are closely related changes the microbiome (e.g., diversity) Determining ecological drivers promoting such is critical knowledge for protecting functions. However, soil-microbe interactions highly variable within environmental gradients may not be consistent across studies. Here we propose that analysis of community dissimilarity (β-diversity) a valuable tool overviewing spatiotemporal changes. Indeed,...

The application of Si or K has proven to be beneficial for the growth plants under saline-alkali stress. However, synergistic effect and in improving growth, ion distribution, partitioning Lolium perenne L. stress remains unclear. In this study, characteristics ion-selective absorption ryegrass (Lolium L.) exposed different levels were evaluated. parameters significantly improved when was applied by itself coupled with low Under a high level, only simultaneous could improve ryegrass. When...

Citizen science is becoming a significant contribution to large scale soil surveys. TeaComposition citizen project introducing the Tea Bag Index (TBI) method students in Australia support research on decomposition using tea bags (green and rooibos). Soil microbial driven an essential function that releases organic matter (SOM) nutrients, i.e., ecosystem services. The TBI experiments enable citizens understand this process (increasing connectivity) information valuable for assessing urban...

The continuum of soil organic carbon is currently not well represented by any single metric. Permanganate oxidizable (POXC) has been widely utilized as a condition indicator due to its correlation with biological indicators and sensitivity management effects over relatively short time periods. However, the ability POXC represent carbon, how this could improve characterization effects, sufficiently explored. This study investigated relationship between permanganate concentration across nine...

Context The Tea Bag Index (TBI) evaluates the rate of organic matter decomposition using Lipton tea bags. However, this bag cannot be easily found in Australia, having to imported from Europe. 90-day incubation period also poses problems for school and citizen science projects, such as missing bags organism-induced damage. Aims study aims to: (1) investigate suitable alternative Australian brands studies; (2) assess potential reducing period; (3) evaluate priming effects different substrates...

Fresh water is an increasingly scarce resource in both urban and rural development. As a response to this challenge, non-potable reuse on the rise. This research explored potential off-grid system for purification, consisting of staircase wetland with terracotta pot plants working as filter greywater. study further investigated physicochemical properties greywater soil before after purification. The removal total suspended solids, coliforms, fecal etc., was always between 90 99%. Results...

Environmental awareness has sparked increasing interest in changing the way humans interact with their environment. This includes change paradigm of considering human manure (humanure) not as a waste but valuable bioproduct instead. In this regard, composting is an age-old technique for nutrient recovery that gained renewed interest, it may be sanitary and financially viable solution to closing loop human–nature interactions. work investigates environmental solutions toilet systems are...
