- Abstract:
- ... Winter rye (Secale cereale L.) cover crop (RCC) has potential to reduce NO₃–N loss from corn (Zea mays L.) and soybean [Glycine max (L.) Merr.] fields. However, RCC effects on annual crop productivity and corn optimal N fertilization requirement are unclear. The objectives were to evaluate corn and soybean yield response to RCC and corn optimal N rate. Treatments were no-RCC and RCC with six ferti ...

- Abstract:
- ... Assessment of the Freundlich sorption parameters of pesticides is an important element of their environmental risk assessment (especially leaching to groundwater), and therefore these parameters must be accurately assessed. In this work, the effect of random and systematic errors on the accuracy of the Freundlich sorption parameters was assessed for pesticide–soil sorption studies using Monte Carl ...

- Abstract:
- ... Iron and manganese oxides are common minerals in a wide range of soils, and they largely control the fate of P. It is often implicitly assumed that phosphate does not exchange O atoms with minerals and water during adsorption, desorption, and precipitation reactions, but this has not yet been fully verified. In this study, we applied an ¹⁸O stable isotope labeling technique to individually label O ...

- Abstract:
- ... Diffuse reflectance Fourier transformed mid-infrared (DRIFT-MIR) spectroscopy can predict many soil properties but extractable nutrients are often predicted poorly. This paper tested the combined DRIFT-MIR and total X-ray fluorescence (TXRF) spectroscopy analysis for prediction of soil properties related to soil fertility. A total of 700 soil samples from 44 stratified randomly located 100-km² sen ...

- Abstract:
- ... Although ammonia-oxidizing archaea (AOA) and bacteria (AOB) coexist in most non-acidic agricultural soils, the factors that influence their relative contributions to soil nitrification activity remain unclear. A 2- to 4-d whole soil microcosm assay was developed, utilizing the aliphatic C₈ alkyne 1-octyne to inactivate AOB-driven nitrification activity without impacting AOA nitrification activity. ...

In the present study, we examined the impacts of ferrihydrite surfaces on the oxidation of dissolved Mn(II) and concurrent formation of Mn(III/IV) (oxyhydr)oxides under various conditions. In the absence of ferrihydrite, the oxidation products of 24 mM Mn(II) by atmospheric O₂ are manganite ...

We currently lack critical information on how grassland soil microbial dynamics will be altered by climate change, and the seasonal dependency of microbial responses. We measured soil microbial biomass, community composition, enz ...

- Abstract:
- ... Soil conservation practices are growingly used with different aims such as reducing fuel consumption and preserving soil organic carbon (SOC). Among others, reduced tillage (RT) often replaces conventional tillage (CT). However, the compared impact of these practices on soil quality remains a matter of controversy. Moreover, the various changes expected are rarely considered all together though th ...

Knowledge of vertical patterns of soil organic C (SOC) and soil total N (STN) can improve our understanding of the dynamics of SOC and STN along a profile and the potential response of SOC and STN to climate change. However, such knowledge is limited. In this study, three common Tibetan forest types, dominated by Abies, Pinus, and Picea species, were sampled across a large altitude gradient (1700– ...

However, little is known about the same in remolded samples that resemble the field condition after plowing. Moreover, the effect of added fresh organic matter (OM) on the anisotropy has attracted little attention. In this study, rice (Oryza sativa L.) husks and rice straw were added to a Japan ...

The heat pulse (HP) method is the standard for measuring thermal properties of unfrozen soils, but its application in partially frozen soils is confounded by melting and refreezing of ice that changes the properties being measured, and the most widely used data analysis models do not account for these latent heat fluxes. This study combined time domain reflectometry (TDR) and HP methods to quantif ...

The resulting δ¹⁵N patterns may be useful for discerning ecosystem differences in N cycling. We studied two ecosystems, longleaf pine (Pinus palustris Mill.)–wiregrass (Aristida stricta Michx.) (LLP) and Appalachian hardwood (AHW) fores ...

Composts and soil conditioners may be useful soil amendments to provide organic matter as well as nutrients such as N and P, but net N mineralized and P released can vary greatly among materials. Consequently, it is important to identify the material characteristics that control these processes. Furthermore, the magnitude of these processes may be affected by particle size. We conducted two labora ...
