Abstract Evapotranspiration (ET) is the main ecological and soil water consumption process in terrestrial ecosystems. Previous studies have investigated ET partitioning across sites and plants; however, direct comparisons of water consumption before and after the transition from one crop to another are scarce. The variation in and proportion of ET and its subcomponents as well as the change in soil water storage (SWS) were compared in maize ( Zea mays L.) croplands and apple ( Malus domestica auct. non Borkh. cv. Fuji) orchards in four active (approximately May to September) and three inactive growth periods on the southern Loess Plateau, China. Soil water evaporation ( E s ) accounted for 36.3 and 37.7% of the total ET for cropland and orchard, respectively, in the active growth period. The canopy interception ( I c ) significantly differed between cropland and orchard. The mean I c /ET for cropland and orchard was 23.1 and 22.7%, respectively, in the active growth period, showing that the effects of I c on ET partitioning should not be ignored. The mean ratio of transpiration ( T ) to ET for cropland was 2.8% less than that for orchard during the active growth period. The T /ET of cropland peaked twice in each active growth period. Precipitation ( P ) met the water consumption requirements of crop growth in the active growth period. The ET of cropland and orchard in the inactive growth period accounted for 29.4 and 31.8% of the ET for the hydrological year, respectively. These results help assess water consumption and soil sustainability under changes in crops in dryland agricultural ecosystems.

Many models have been constructed in an attempt to describe the dynamics of soil organic‐matter (SOM) turnover, most of which include 2 to 3 kinetically defined organic‐matter pools. Physical and chemical definition of these conceptualized SOM pools has been difficult. We describe a simple method for dispersion of soil to isolate a particulate organic‐matter (POM) fraction that may represent an important SOM pool in grassland soils. The POM fraction was isolated by dispersing the soil in 5 g L−1hexametaphosphate and passing the dispersed soil samples through a 53‐µm sieve. We compared POM and mineral‐associated C among three tillage treatments (20 yr under cultivation) and an undisturbed grassland at Sidney, NE. The POM C in the native sod represented 39% of the total soil organic C. Twenty years of bare‐fallow, stubble‐mulch, and no‐till management reduced the C content in this fraction to 18, 19, and 25%, respectively, of the total organic C. The mineral‐associated organic‐matter fraction showed no reduction in C content in the bare‐fallow treatment compared with the grassland soil but increased in the no‐till and stubble‐mulch treatments. Nitrogen dynamics generally mirrored those observed for C. Analysis of the POM fraction for lignin and cellulose content indicated that this fraction was 47% lignin and had a lignocellulose index of 0.7. The stable C‐isotope composition of the POM fraction suggests that wheat‐derived POM turns over faster than grass‐derived POM. We suggest the POM fraction closely matches the characteristics of a SOM pool variously described as slow, decomposable, or stabilized organic matter.

Particulate Soil Organic‐Matter Changes across a Grassland Cultivation Sequence

The rapid rewetting of a dry soil often yields a pulse in soil CO2 production that persists for 2 to 6 d. This phenomenon is a common occurrence in surface soils, yet the mechanism responsible for producing the CO2 pulse has not been positively identified. We studied the effects of a single drying and rewetting event on soil C pools, to identify which specific C substrates are mineralized to produce the observed pulse in respiration rates. We labeled two soils with 14C-glucose and measured the enrichment and pool sizes of the released CO2, extractable biomass C, and extractable soil organic matter (SOM-C) throughout a drying and rewetting cycle. After rewetting, respiration rates were 475 to 370% higher than the rates measured before the dry down. The enrichment of the released CO2 was 1 to 2 times higher than the enrichment of the extractable biomass C pools and 10 to 20 times higher than the enrichment of the extractable organic C, suggesting that the CO2 pulse was generated entirely from the mineralization of microbial biomass C. However, there was no evidence of substantial microbial cell lysis on rewetting. We hypothesize that the pulse of CO2 is generated by the rapid mineralization of highly enriched intracellular compounds as a response by the microbial biomass to the rapid increase in soil water potentials. The drying and rewetting process also releases physically protected SOM, increasing the amount of extractable SOM-C by up to 200%. The additional SOM-C rendered soluble by the rewetting event did not contribute substantially to the rewetting CO2 pulse. Overall, the rapid rewetting of a dry soil can influence soil C cycling in the short-term, by increasing the microbial mineralization of cytoplasmic solutes, and in the longer-term, by decreasing the total amount of SOM physically protected within microaggregates.

Abstract Monitoring CO 2 or O 2 concentrations within a closed, volume‐defined chamber is widely used to quantify soil respiration during laboratory soil incubation experiments. The standard method of using periodic manual gas sampling is costly, labor‐intensive, and frequently fails to capture the aerobic respiration process. Thus, tools that allow continuous, real‐time tracking of CO 2 and O 2 concentration changes are needed for soil respiration research. This study presents a new, portable, low‐cost (∼$700), open‐source sensor system to measure CO 2 and O 2 concentrations in four closed chambers. We provided non‐engineering end‐users with step‐by‐step instructions on how to build the system, enabling replication and customization. System performance was tested by comparing two respiration rates using the same soil—soil with and without glucose added for 1 week. Consistent CO 2 production and O 2 consumption rates were measured at 1‐min intervals, and the reliability of the system was validated by a trace gas analyzer. Two distinctive continuous apparent respiratory quotient time series between two soil treatments were observed, with higher values of CO 2 in glucose soil, demonstrating the ability of the system to capture ongoing respiration processes and sufficient sensitivity to distinguish differences among respiration substrates (i.e., glucose). The tested performance of the system highlights its capabilities for soil respiration research and the potential for further adoption in real‐time gas monitoring applications.

Abstract In the coming decades, humanity will be faced with the challenge of feeding 10 billion people and managing large quantities of solid waste. These issues can be mitigated through the development of sustainable fertilizers derived from electrochemically treated waste activated sludge (EWAS) while promoting a nitrogen circular economy. This study investigates the chemistry of novel fertilizers to determine their soil chemistry dynamics. Untreated waste activated sludge (WAS) and EWAS were applied to agricultural soil and potting mix, and the resulting aqueous samples were analyzed to determine nitrogen, phosphorous, and carbon adsorption and release behaviors. Commercial inorganic and natural fertilizers were utilized for comparison. X‐ray absorption near‐edge structure (XANES) spectroscopy was performed to characterize phosphorus speciation in the solid phases of the novel fertilizers. Results indicated that EWAS and WAS samples released less total nitrogen into solution than other treatments due to organoclay complexation of biomolecules and differences in the solubility of the nitrogen species. Samples containing EWAS released a higher percentage of organic and total carbon into solution due to the deformation of the structure of the organic matter by the alkaline electrolysis process. The solubility of nitrogen and carbon in the sludge was increased by the electrochemical process. Solid‐phase phosphorus in EWAS and WAS was characterized by XANES analysis as struvite, which is a novel finding with important implications for P management from waste‐based fertilizers. These experimental findings suggest that fertilizing with EWAS could result in reduced runoff and improved soil health while facilitating domestic fertilizer production.

Abstract Biochar as a soil amendment can increase soil carbon sequestration, soil microbial diversity, overall yields, and general soil functioning. To accelerate these effects, biochar is often activated with beneficial soil microbes such as arbuscular mycorrhizal fungi or plant growth promoting bacteria via microbial inocula. However, there has been no comprehensive review of the effects of microbial inoculum additions for biochar amendments. We conducted a meta‐analysis to quantify the crop and soil effects of adding biochar alone compared to adding biochar with a microbial inoculum. The meta‐analysis included 56 studies and examined whether the effects depended on the source of inoculum, inoculum type, or experiment type. We found that microbial inocula increased soil N and soil organic carbon concentrations and crop productivity compared to adding biochar alone. However, these effects were limited to locally sourced and research‐grade inocula, while commercial inoculum products only slightly increased soil P. Fungal inocula had stronger effects than bacterial inocula. Inoculum effects were the strongest in greenhouse studies, increasing N, plant productivity, and fungal abundance, while field studies only increased plant productivity, suggesting that biochar activation with inoculum in on‐farm settings may not provide intended positive effects, and thus alternative methods for biochar activation may be needed.

Abstract There was a long‐time debate about the validation of the convection‐dispersion equation (CDE) and its replacement with the well‐known convective lognormal transfer function model (CLT) to describe solute transport in a heterogeneous soil with uniformity at the longitudinal water flow direction and nonuniformity at the transverse direction. The objective of this study is to prove that the CDE is valid and almost identical to the CLT. Gamma probability density function (pdf) was initially assumed in this study to describe the distribution of pore‐water velocity across capillary tubes in a heterogeneous soil. The capillary bundle model was used to describe solute transport without transverse solute mixing between adjacent tubes. The inverse‐gamma function, a new mathematical solution of the CDE differential equation with scale‐dependent dispersivity, was initially derived from the capillary bundle model and the gamma pdf. The only difference between the inverse‐gamma function and the CLT is that lognormal pdf of pore‐water velocity is assumed in the CLT while the two pdfs are close to each other. The inverse‐gamma function and the CLT were tested with the published data from the miscible displacement experiments on the two repacked soils with different aggregate sizes. Results show that both the inverse‐gamma function and the CLT fit the measured breakthrough curves in the miscible displacement experiments. The estimates of the squared coefficient of variation of the pore‐water velocity in the gamma pdf were 0.314 and 0.0582 for the two soils, and they were consistent with the lognormal pdf in the CLT.

Abstract In recent decades, the determination of particle size distribution (PSD) using the laser diffraction method (LDM) has become increasingly common, supplanting traditional sedimentation techniques. Advances in everything from sample preparation to software settings have been realized globally, whether through recommendations from laser diffraction (LD) manufacturers or through user experiences. These developments seek to enhance accuracy and diminish the uncertainties associated with new methodologies. Particularly in the determination of PSD using LDM on various LD instruments and in comparison with the sieve–pipette method (SPM), discrepancies in PSD frequently arise. This article aims to mitigate these discrepancies by predefining parameters, specifically through the adjustment of LD software settings and sample preparation (employing a uniform set of dispersed samples in potassium hydroxide) on two widely used LD instruments for soil measurements: Mastersizer 3000 and Analysette 22. Additionally, these samples were analyzed using the traditional SPM (ISO 11277, 1998), with the results from LDM and SPM subsequently compared. The paper also explores the impact, range of user options, and limitations of predefined software settings on both LD instruments. Eighty soil samples were analyzed for PSD, collected from arable land in the cadastral area of Hrušky, district of Břeclav (Czech Republic), in spring 2022, from depths of 0‐ to 10‐cm and 10‐ to 20‐cm. Significant differences in PSD were confirmed, although the trends of the grain size distribution curves were very similar to those of LDM. Results from the Mastersizer underestimated the clay fraction by an average of 17% compared to SPM, at the expense of the sand fraction, whereas the silt fraction was underestimated by a maximum of 4%. Conversely, Analysette 22 overestimated the silt fraction by an average of 37% at the expense of the sand fraction, confirming only a slight difference in the clay fraction: 3%. Moreover, the quantity of sample entering the dispersion unit was identified as a significant issue when comparing LD instruments, despite the obscuration value being nearly identical, that is, 20%–30%. Therefore, it was not possible to achieve the same or similar weight when introducing suspension into circulation. The robustness of the obtained results underscores the importance of understanding input parameters when interpreting results between different methods.
