- Abstract
- The rational use of farmyard manure is a crucial issue for the future of agriculture. Farmyard manure enable substantial savings on chemical fertilizers and improve soil quality by adding organic matter, stimulating biological activity and improving soil structure. To optimize their effectiveness while ensuring that there is no risk to the environment (leaching of nitrogen and/or phosphorus), it is essential that farmers analyze their manures to determine their actual chemical composition. Standard laboratory analysis can be time-consuming and costly. Near infrared spectroscopy (NIRS) is an attractive alternative as it is a fast, non-destructive, reproducible and cost-effective method. However, to develop robust and accurate predictive models, accurate reference and spectral data are required. For a given farmyard manure, the composition can vary enormously depending on animal species, feed type, housing and storage conditions.
