Assessment of soil organic carbon at local scale with spiked NIR calibrations: effects of selection and extra-weighting on the spiking subset

Guerrero, C.; Stenberg, B.; Wetterlind, J.; Viscarra Rossel, R. A.; Maestre, F. T.; Mouazen, Abdul Mounem; Zornoza, R.; Ruiz-Sinoga, J. D.; Kuang, Boyan Y. (Wiley, 2014-01-17)

Spiking is a useful approach to improve the accuracy of regional or national calibrations when they are used to predict at local scales. To do this, a small subset of local samples (spiking subset) is added to recalibrate ...
Effect of spiking strategy and ratio on calibration of on-line visible and near infrared soil sensor for measurement in European farms

Kuang, Boyan Y.; Mouazen, Abdul Mounem (Elsevier Science B.V., Amsterdam., 2013-04-02)

A previously developed on-line visible and near infrared (vis-NIR) spectroscopy-based soil measurement system was implemented for the measurement of soil organic carbon (OC), total nitrogen (TN) and moisture content (MC) ...
Influence of the number of samples on prediction error of visible and near infrared spectroscopy of selected soil properties at the farm scale.

Kuang, Boyan Y.; Mouazen, Abdul Mounem (Blackwell Publishing Ltd, 2013-01-23)

Although visible and near infrared (vis-NIR) spectroscopy has proved to be a fast, inexpensive and relatively accurate tool to measure soil properties, considerable research is required to optimise the calibration procedure ...
Methods and procedures for automatic collection and management of data acquired from on-the-go sensors with application to on-the-go soil sensors.

Peets, Sven; Mouazen, Abdul Mounem; Blackburn, Kim; Kuang, Boyan Y.; Wiebensohn, Jens (Elsevier Science B.V., Amsterdam., 2012-02-01)

Sensors for on-the-go collection of data on soil and crop have become essential for successful implementation of precision agriculture. This paper analyses the potentials and develops general procedures for onthe- go ...
Non-biased prediction of soil organic carbon and total nitrogen with vis-NIR spectroscopy, as affected by soil moisture content and texture

Kuang, Boyan Y.; Mouazen, Abdul Mounem (Elsevier Science B.V., Amsterdam, 2013-03-01)

This study was undertaken to evaluate the effects of moisture content (MC) and texture on the prediction of soil organic carbon (OC) and total nitrogen (TN) with visible and near infrared (vis-NIR) spectroscopy under ...
On-line measurement of soil properties without direct spectral response in near infrared spectral range

Marin-González, O.; Kuang, Boyan Y.; Quraishi, M. Z.; Munoz-Garcia, M. A.; Mouazen, Abdul Mounem (Elsevier Science B.V., Amsterdam., 2013-08-01)

So far, the majority of reports on on-line measurement considered soil properties with direct spectral responses in near infrared spectroscopy (NIRS). This work reports on the results of on-line measurement of soil properties ...
On-line measurement of some selected soil properties for controlled input crop management systems

Kuang, Boyan Y. (Cranfield University, 2012-02)

The evaluation of the soil spatial variability using a fast, robust and cheap tool is one of the key steps towards the implementation of Precision Agriculture (PA) successfully. Soil organic carbon (OC), soil total nitrogen ...
Potential of on-line visible and near infrared spectroscopy for measurement of pH for deriving variable rate lime recommendations

Tekin, Yücel; Kuang, Boyan Y.; Mouazen, Abdul Mounem (MDPI AG, 2013-08-08)

This paper aims at exploring the potential of visible and near infrared (vis-NIR) spectroscopy for on-line measurement of soil pH, with the intention to produce variable rate lime recommendation maps. An on-line vis-NIR ...
Prediction of soil TN and TC at a farm-scale using VIS-NIR spectroscopy

Yang, Haiqing Q.; Kuang, Boyan Y.; Mouazen, Abdul Mounem (2011-12-31)

Building cost-effective models is of academic and practical value for fast measurement of soil properties, especially at a farm-scale. The aim of this study is to build quantitative models for soil total nitrogen (TN) ...
Size estimation of tomato fruits based on spectroscopic analysis

Yang, Haiqing Q.; Kuang, Boyan Y.; Mouazen, Abdul Mounem (2011-12-31)

This study used visible and near-infrared (VIS-NIR) spectroscopy for size estimation of tomato fruits of three cultivars. A mobile, fibre-type, VIS-NIR spectrophotometer (AgroSpec, Tec 5, Germany) with spectral range of ...
