    Abstract: A method for determining a weed percentage in a viewing section (10) of a field (20) is described. Actual spectral information is acquired by means of at least one optical viewing section sensor (12a, b) which is directed to the viewing section (10). Furthermore, reference spectral information is acquired by means of an optical reference sensor (32), which is directed to a reference section (30) of the same soil surface (22). A difference between the actual spectral information and the reference spectral information is determined. Finally, the difference is applied to the weed percentage by means of a predefined image. Furthermore, an agricultural control device (100) is described which is suitable for the implementation of the method.

    Abstract: The invention relates to a method for detecting at least one chemical compound V that is contained in a medium (312). Said method has a verification step (420), in which the presence of the compound V in the medium (312) is determined. In addition, the method has an analysis step (424), in which a concentration c of the chemical compound or compounds V is determined. The verification step comprises the following sub-steps: (a1) the medium (312) is irradiated with first analysis radiation (316) of a variable wavelength λ, said wavelength λ having at least two different values; (a2) a spectral response function A(λ) is generated using the radiation (324) that has been absorbed and/or emitted and/or reflected and/or scattered by the medium (312), in response to the first analysis radiation (316); (a3) at least one spectral correlation function K(δλ) is formed by comparing the spectral response function(s) A(λ) with at least one model function R(λ + δλ), in which said model function(s) R(λ) represent(s) a spectral measured function of a medium (312) that contains the chemical compound V and δλ is a co-ordinate shift; (a4) the spectral correlation function(s) K(δλ) is examined in a model identification step (418) and conclusions are drawn as to whether the chemical compound(s) V is or are contained in the medium (312). The analysis step (424) has the following sub-steps: (b1) the medium (312) is irradiated with at least second analysis radiation (318) that has at least one excitation wavelength λEX; (b2) at least one spectral analysis function B(λEX, λRES) is generated using the radiation (326) of the response wavelength λRES that has been absorbed and/or emitted and/or reflected and/or scattered by the medium (312), in response to the second analysis radiation (318) of wavelength λEX and conclusions concerning the concentration c are drawn.
