Theory and Guidelines for the Application of the Geophysical Sensor EM38

open access: yesSensors, 2019
Characterization of spatial soil variability is key for a better understanding of soils. To arrive at such information geophysical techniques have been used in the last two decades.

Spatial aspects of applied Soil Science

open access: yesБюллетень Почвенного института им. В.В. Докучаева, 2020
The analysis of peculiarities of applied use of soil data has been carried out. It is shown that most of practical tasks require spatial information about soils and their properties. In this regard, a soil map is considered as a kind of interface between

Visible and near infrared spectroscopy in soil science [PDF]

open access: yes, 2010
This chapter provides a review on the state of soil visible–near infrared (vis–NIR) spectroscopy. Our intention is for the review to serve as a source of up-to date information on the past and current role of vis–NIR spectroscopy in soil science.

Field-scale validation of an automated soil nitrate extraction and measurement system [PDF]

open access: yes
One of the many gaps that needs to be solved by precision agriculture technologies is the availability of an economic, automated, on-the-go mapping system that can be used to obtain intensive and accurate ‘real-time’ data on the levels of nitrate ...

Data-Gap Filling to Understand the Dynamic Feedback Pattern of Soil

open access: yesRemote Sensing, 2015
Detailed and accurate information on the spatial variation of soil over low-relief areas is a critical component of environmental studies and agricultural management. Early studies show that the pattern of soil dynamics provides comprehensive information

Identification of favorable alleles from exotic Upland cotton lines for fiber quality improvement using multiple association models

open access: yesFrontiers in Plant Science
Upland cotton (Gossypium hirsutum) faces the challenge of limited genetic diversity in the elite or improved gene pool. To address this issue, we explored alleles contributed by five ‘converted’ exotic lines sampling most of the undomesticated botanical ...

Mapping soils in Ireland

open access: yes, 2014
peer-reviewed This project is jointly funded by Teagasc and EPA STRIVE funding. Harmonised soil data across Europe with a 1:250 000 geo-referenced soil database will allow for exchange of data across member states and the provide the information needed for reporting on issues re-lating to soil quality under a future Soil Framework Directive.

Vis-NIR soil spectral library of the Hungarian Soil Degradation Observation System

open access: yesScientific Data
Since soil spectroscopy is considered to be a fast, simple, accurate and non-destructive analytical method, its application can be integrated with wet analysis as an alternative. Therefore, development of national-level soil spectral libraries containing

Large scale soil survey and mapping based on the spatial variation of soil horizons

open access: yes浙江大学学报. 农业与生命科学版, 2006
This paper put forward a proposal of large-scale soil survey and mapping based on characterization of the spatial variation of soil horizons. The framework of the method can be divided into four steps: (i) positioning of observation points with Global ...

Evolutionarily divergent DUF4465 domains have a common vitamin B12‐binding function

open access: yesFEBS Open Bio, EarlyView.
We show that DUF4465 family proteins, widespread across bacteria from gut microbiomes, hydrothermal vents, and soil, share a common vitamin B12‐binding function. These augmented β‐jellyroll proteins bind vitamin B12 via extended loops. Our findings establish sequence‐diverse DUF4465 proteins as a widespread class of B12‐binding proteins, highlighting ...
