Development of near infrared (NIR) spectroscopic methods to predict carbon, nitrogen, silicon, phosphorus and potassium levels in mill by-products* [Full subscriber]

Mill by-products have been utilised on cane farms as a nutrient source and soil ameliorant for many years; however, the nutrient content is not usually measured on a regular basis. Concerns exist over the long term application of mill mud and ash without appropriate product monitoring, but these can be at least partially addressed by developing simple, rapid measurement techniques that can be employed at the sugar mill. This paper presents near infrared (NIR) spectroscopic methods for the prediction of nutrient elements: carbon (C), nitrogen (N), silicon (Si), phosphorus (P) and potassium (K) levels in mill mud and mixed mill…
