Prediction by near infrared spectroscopy of the biochemical composition of various raw materials used in the organic fertiliser industry

چکیده
Added organic materials [1], composts and organic fertilisers are involved in building soil organic matter. They are a factor in soil property improvement, and can represent an important source of nutrients for both plants and soil organisms. Even a century ago [2], the composition of added organic materials was thought to have a direct influence on organic matter transformation. Intense work is still devoted to investigating the relationships between the characteristics and the transformations of added organic materials [3]. The fibre content, estimated by Van Soest fractions [4], proved to be a good indicator of the potential capacity of carbon and nitrogen transformations [5 11].

Potential of Near-Infrared Reflectance Spectroscopy (NIRS) to Predict Nutrient Composition of Bromus tomentellus
Determination of forage quality of available species is one of the fundamentalfactors for the management of rangelands. Near-Infrared Reflectance Spectroscopy (NIRS)was used to analysis the Nitrogen (N), Acid Detergent Fiber (ADF), Dry MatterDigestibility (DMD) and Metabolizable Energy (ME) content of three phenological stages(vegetative, flowering and seeding) of Bromus tomentellus samples in ...

Chemical assessments of forage clearly determine the forage quality; however, traditional methods of analysis are somehow time consuming, costly, and technically demanding. Near Infrared Reflectance Spectroscopy (NIRS) has been reported as a method for evaluating chemical composition of agriculture products, food, and forage and has several advantages over chemical analyses such as conducting c...
