Development of on-the-go soil nitrogen mapping system for site specific management [PDF]

, 2013
Site specific management can potentially improve both economic and ecological outcomes in agriculture. Effective site specific management requires strong and temporally consistent relationship among identified management zones; underlying soil physical ...

Biodiversity and ecosystem function in soil [PDF]

, 2005
1. Soils are one of the last great frontiers for biodiversity research and are home to an extraordinary range of microbial and animal groups. Biological activities in soils drive many of the key ecosystem processes that govern the global system ...

Divergent Responses of Bacterial Communities to Permafrost Degradation and Their Associations With Carbon Across Vertical Profiles

Advanced Science, EarlyView.
Bacterial α‐diversity decreases, but stochasticity and community stability increase across the 15 m‐depth vertical profiles and along the degraded gradient within the active layer. The abundance and interaction of core taxa mainly control community stability in the active and permafrost layers, respectively.

Preprocessing procedures and supervised classification applied to a database of systematic soil survey

Scientia Agricola, 2019
: Data Mining techniques play an important role in the prediction of soil spatial distribution in systematic soil surveying, though existing methodologies still lack standardization and a full understanding of their capabilities. The aim of this work was

Mapping Statewide Flash Flood Potential Index (FFPI) in Indiana [PDF]

, 2011
National Weather Service (NWS) employees must make forecasting decisions on a daily basis. These forecasts are important to save people’s lives and property. One area where the NWS has very little guidance is flash flood prediction.

Integrated Single‐Cell and Spatial Transcriptomics Reveal Cell‐Type‐Specific Immune Regulatory Networks in Maize Responding to Southern Corn Rust

Advanced Science, EarlyView.
By integrating single‐nuclei and spatial transcriptomics, this study presents a stereoscopic landscape of maize leaf to Puccinia polysora infection. Epidermal and mesophyll cells initiate primary defenses via RLPs/RLKs and jasmonic acid signaling. Cell‐cell communication analyses further reveal the underlying the dynamics of the underlying immune ...

Remote sensing data applied to the evaluation of soil erosion caused by land-use. Ribeirao Anhumas Basin Area: A case study [PDF]

Formerly covered by a tropical forest, the study area was deforested in the early 40's for coffee plantation and cattle raising, which caused intense gully erosion problems.

Divergent Regulatory Effects of Jasmonic Acid on Tomato Lycopene Biosynthesis Under Light and Dark Conditions

Advanced Science, EarlyView.
This study reveals the mechanism by which jasmonic acid (JA) regulates lycopene synthesis under light and dark conditions. In light, JA activates SlMYC2, which suppresses SlPIF1a and promotes SlPSY1 expression. In darkness, JA induces the acetyltransferase SlNATA1, which acetylates the dark‐accumulated SlPIF1a, thereby repressing SlPSY1 expression ...

Leaching of Mycobacterium avium subsp. paratuberculosis in Soil under In Vitro Conditions

Veterinary Medicine International, 2011
Mycobacterium avium subsp paratuberculosis (Map), the causative agent of Johne's disease, has a robust ability to survive in the environment. However, the ability of Map to migrate through soil to drainage tiles or ground water, leave the farm, and leak ...

STATE SOIL MAP AND ITS CREATORS

Бюллетень Почвенного института им. В.В. Докучаева, 2015
The State Soil Map (SSM) on a scale of 1 : 1 M is the greatest product of Russian small-scale soil cartography that accumulates data on soils of the Former Soviet Union for the entire period of the development of Dokuchaev's pedology. The work on the SSM
