Two Methods of Near Infrared Reflectance Spectroscopy for Determining the Digestibility and Energy Value of Feeds [PDF]

, 1997
Two groups of rations with known in vivo digestibility and energy values were used in this study. These rations were composed of Italian ryegrass only (lRO. n = 45), and combination of Italian ryegrass and concentrates (lRC, n = 58).

The use of near infrared (NIR) spectroscopy to improve soil mapping at the farm scale [PDF]

, 2008
The creation of fine resolution soil maps is hampered by the increasing costs associated with conventional laboratory analyses of soil. In this study, near infrared (NIR) reflectance spectroscopy was used to reduce the number of conventional soil ...

Near infrared reflectance spectroscopy compared with soil clay and organic matter content for estimating within-field variation in N uptake in cereals [PDF]

, 2008
Adjusting fertiliser applications to within-field variations in nitrogen (N) mineralisation during the growing season can increase yields, improve crop quality, reduce costs and decrease nutrient losses to the environment. Predicting such variations at a
