A recently emerged desalinization method is achieved by modifying clays using biochar. However, unsaturated soil responses of biochar‐engineered clays in saline environments under drought conditions remain unknown. This study aims to investigate soil shrinkage and water retention characteristics of biochar‐amended kaolin and bentonite under saline conditions. Soil shrinkage and water retention tests were conducted on clays (with and without biochar addition) with various porewater salinity (i.e., 0%–10%). Physiochemical properties (including zeta potential and porewater pH) were measured to interpret particle–fluid interactions. Shrinkage characteristics of kaolin and bentonite exhibited sensitivity and insensitivity to the porewater salinity, respectively. This phenomenon was explained by hydrogen‐sodium ion exchange and deprotonation phenomenon occurring on kaolin and bentonite, respectively. Biochar significantly alleviated the salinity‐induced shrinkage of clays by increasing the shrinkage limit of kaolin and bentonite by 6%–14% and 50%–107%, respectively ( p < 0.05). This was attributed to the porous structure and hydrophilic functionality of biochar that immobilized sodium ions through ion exchange and protonation reactions. The air entry value of clays significantly increased with porewater salinity and biochar addition due to the reduction of void ratio and enhanced capillarity, respectively. An empirical equation was proposed to predict the shrinkage limit of clay in various saline conditions. It highlighted that the application of biochar‐engineered clays could contribute to the desalination and the improvement of resistance to shrinkage damage in hydro‐chemical barriers.","PeriodicalId":22142,"journal":{"name":"Soil Science Society of America Journal","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135944298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is especially true in coarse‐textured media used in geotechnical engineering, greenhouse, and landscape industries, where subtle changes in water status may lead to plant stress. However, based on the traditional hanging water column method, water retention measurements are laborious and time consuming because of the stepwise manual water potential adjustments and wait‐time requirements for equilibrium conditions to develop. Therefore, we designed and fabricated an automated system to collect wetting‐ and drying‐water retention data from coarse porous media. The basic system consisted of (1) a compound pressure transducer (± 70‐cm range) providing both the porous medium's volumetric water content ( θ ) and matric potential ( h ) determinations, (2) a 70‐cm linear actuator to vertically position a 50‐mL burette, and (3) a diffuse laser distance sensor positioned by a 10‐cm linear actuator to monitor the burette's vertical position relative to the sample position. This automated system determined the initial drying process beginning with a fully saturated sample ( h = 0 cm) and determined subsequent wetting‐ and drying‐water retention curves. Our automated water retention measurements in quartz sand (ASTM C778‐21) exhibited maximum‐ and minimum‐standard deviation in θ of 0.013 and 0.00044 cm 3 cm −3 , respectively. Parameters of the hysteretic water retention model of quartz sand were characterized using repeated measurements. Results of this research included the creation of an automated water retention system and the well‐characterized hydraulic parameters for the original well‐graded and narrowly sieved particle sizes of quartz sand.","PeriodicalId":22142,"journal":{"name":"Soil Science Society of America Journal","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135944287","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Micronutrients can be added as coated P fertilizers, creating multi‐nutrient fertilizers for crops to address this issue. The objective of this study was to quantify the diffusion and availability of P, B, Cu, Mn, and Zn in coated P fertilizers. Another objective was to evaluate the nutrient uptake, partitioning, and yield of soybeans. Treatments were monoammonium phosphate and NPS (nitrogen, phosphorus, sulfur) fertilizer coated with Maxxi‐Phós and either Wolftrax, Microsol, or MIB Precise. Applied concentrations of B and Cu varied between 0.15% and 0.05%. The Mn and Zn ranged from 0.45% to 0.15%. Nutrient accumulation and recovery were assessed in the greenhouse and field trials. P diffusion ranged from 5.58 to 18.88 mm in 336 h. Micronutrient use efficiencies varied according to the soybean ( Glycine max ) phenological stages, with emphasis on the V4 stage, which resulted in the following values: B (0.65% to 13.89%), Cu (6.73% to 62.84%), Mn (0.73% to 3.36%), and Zn (0.01% to 2.34%). Nutrient exports were: 55.7 kg of P 2 O 5 ha −1 , 209.6 g of B ha −1 , 109 g of Mn ha −1 , 216.7 g of Zn ha −1 , and 64.3 g of Cu ha −1 . There was significant absorption ( p ≤ 0.05) of B, Mn, and Zn at stages R1–R5.1 in the field trial, whereas it was from V4 to R1 for Cu.

We evaluated the impact of corn ( Zea may s L.) stover removal level (SRL) on soil microbial biomass (MB) and extracellular enzyme activities (EEAs) in irrigated, continuous corn located in eastern Nebraska. Soil fatty acid‐methyl esters (FAMEs) and EEA of eight soil enzymes were measured over 2 years, 0‐ to 20‐cm soil depth, under conventional disk tillage (CT) and no‐till (NT) under three SRLs. Soil chemical properties were measured as explanatory variables for changes in soil microbial communities and their enzymatic potential. Potential EEA of all enzymes decreased with stover removal and tillage. Soil bacterial biomass (BB) and fungal biomass (FB) decreased with SRL, while mycorrhizal biomass was unresponsive. Impacts of tillage on MB groups varied by year; however, FB was consistently higher under CT. At all growth stages, NT with all stover retained, a “soil conservation target” had distinct soil enzyme and bacterial FAME profiles compared to CT across all SRLs and to NT under high and sometimes moderate SRLs. Principal component analysis of soil properties was dominated by SRL with EEAs, BB, soil organic matter (SOM), water‐extractable carbon, and H 3 A‐extractable potassium being positively correlated to stover retention. Reduced input of microbial substrates also led to a loss of fine particulate organic matter, an indicator correlated to stable macroaggregation. Because NT partially ameliorated the negative impact of stover removal on BB, SOM fractions, and soil enzymes critical to nutrient cycling, pairing NT with stover removal may be more sustainable in the long term.","PeriodicalId":22142,"journal":{"name":"Soil Science Society of America Journal","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135923593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These soils exhibit low organic matter, poor soil aggregate stability, and ultimately low infiltration rates that decrease rainfed crop productivity and increase irrigation water demand. This research quantified the effects of soil management practices on rainfed maize ( Zea mays L.) yield, furrow water infiltration, and soil moisture in Commerce very fine sandy loam and silt loam near Stoneville, Mississippi, USA. The six treatments included conventional tillage (CT), cereal rye (CR; Secale cereale ), furrow diking (FD), no‐till (NT), polyacrylamide (PAM), and subsoiling (SS). No other treatment achieved a significantly higher maize grain yield than the CT control treatment in both years consistently. Single‐ring infiltrometer results indicated no significant differences between CT, CR, PAM, and SS in 2022 and between CT and NT in 2021. Neutron attenuation found that total soil water within the top 1 m was not significantly different among CT, FD, and SS on any of the eight measurement dates throughout the 2022 maize reproductive period. However, soil moisture was numerically lower for FD in the late reproductive stages. These findings suggest that environmental factors and other agronomic operations may counteract conservation practices, limiting their effectiveness at reducing irrigation requirements to mitigate groundwater depletion in the Mississippi River Valley Alluvial Aquifer.

Using a multi‐wave particle size analyzer, fibric and sapric soil samples were circulated in deionized water through a closed aqueous loop at 9.6 L min−1 and the following methodological parameters were investigated: pre‐treatment, circulation time, and refractive index. Our results show that pre‐treatment for organic soil samples is dependent upon the degree of decomposition; the intact and dispersed PSDs for fibrous samples were not different, whereas the PSDs for sapric samples showed a shift from 500 to 2000 (intact) μm to 5 to 100 (dispersed) μm. Circulation time was investigated using mean particle diameter and specific surface area. We demonstrated that as circulation time increased, the mean particle diameter decreased and the specific surface area increased out to 30 minutes as mechanical dispersion and/or the fragmentation of organic particles occurred. However, circulation time after 5 minutes is not significantly different in terms of mean particle diameter. To investigate refractive index, 12 optical models were created. When determined across all intact samples, uncertainty was low within individual bins, with a maximum value of 0.07 ± 0.04% v/v. For dispersed samples, uncertainty increased within the silt sized region and had a maximum value of 0.17 ± 0.07% v/v. This study demonstrates that the particle diameter of organic soil material can be measured by LD with comparable certainty as mineral soil material using the methodological approach in this study.This article is protected by copyright.

We quantified the change in soil chemical properties 12 years after cattle manure and swine effluent applications had ceased. Data was collected in 2008 (termination of applications) and 2020 on a long‐term animal waste study at the Kansas State University, Southwest Research‐Extension Center near Tribune, KS. Treatments were three levels of cattle manure and swine effluent (P, N, 2N) and an untreated control. Soil profile NO3‐N declined 78–95%, 70–82%, and 58% from the initial amount in 2008 compared to the amount remaining in 2020 in the swine effluent, cattle manure, and an untreated check, respectively. Profile NO3‐N levels were greatly elevated by the P based swine effluent treatment and the 2N rate of both cattle manure and swine effluent and remained high (>250 kg ha−1) after 12 years. Total nitrogen in the surface soil decreased by 11–27% for cattle manure treatments with little change in the swine effluent and check treatments. Total carbon concentration in the surface soil decreased from 22–31% for cattle manure treatments and from 7–14% for swine effluent and check treatments. Mehlich‐3 P decreased significantly for the cattle manure treatments (41‐53%) but still remained very high (> 100 mg kg−1). Soil test P levels in the swine treatments were similar to the check treatment. Application of cattle manure and swine effluent has lasting effects on many soil chemical properties long after ceasing applications.This article is protected by copyright.
