In studies on root systems using the soil coring method, roots, crop residues and soil particles extracted after washing of soil samples need to be manually sorted before root quantification. If different species are present in the sample, their discrimination is based on several criteria. In order to reduce the complexity and the time needed for this tedious sorting step, near infrared hyperspectral imaging was used to discriminate all these elements. Images of washed and dried samples were acquired with a camera saving, for each pixel, a near infrared spectrum. These spectra are linked to the physicochemical nature of the elements visible on the hyperspectral images and were analyzed with discriminant algorithms allowing their discrimination and to link each pixel spectrum to the nature of the elements. According to the number of pixels classified as roots and thanks to the linear relationship between the number of pixels and the root biomass in the sample, it was possible to quantify roots in soil samples without manual sorting and weighing. This methodology was successfully tested on winter wheat roots and highlighted the tillage effect on root system development. It was also tested on wheat-pea intercropping in order to quantify separately the roots of each species. [less ▲]

Estimation of root system development is often based on the soil coring method which allows repeated measurements during the growing season in the field as well as in different soil horizons. However, this method is limited due to the time needed to extract roots from soil cores and to manually sort them from crop residues before quantification. To avoid this tedious sorting step and remove operator subjectivity, a procedure based on NIR Hyperspectral Imaging (NIR-HSI) has been developed. [less ▲]

Roots, the belowground part of plants, play a major role in plant development. Their study in field conditions is important to identify suitable soil management practices for suitable crop production but roots are hidden by soil and their study is therefore difficult. Estimation of root system development is often based on the soil coring method which allows repeated measurements during the growing season in the field as well as in different soil horizons. However, this method is limited due to the time needed to extract roots from soil cores and to manually sort them from crop residues before quantification. To avoid this tedious sorting step and remove operator subjectivity, a faster sorting method was developed. Near infrared hyperspectral imaging (NIR-HIS) was tested as a rapid method to quantify the amount of roots in soil samples. [less ▲]

Winter wheat and peas cultivated in association and harvested when grains are dry show promising results in temperate areas. This association reach a good land equivalent ratio, reduce the nitrogen fertilizer needs and obtain high quality harvest. These results are probably explained by the transfer of nitrogen from peas nodules to wheat roots. To test this hypothesis, quantification of nodules is required. Visual counting of nodules is time consuming and discrimination between the two kinds of roots is almost impossible. A new method is therefore needed. Near infrared hyperspectral imaging (NIR-HIS) was tested as a rapid method to quantify the amount of nodules and roots of each species in soil samples. [less ▲]
