Active optical sensing of canopies in pasture management
(NZ Grassland Association, 2015)
Commercial units of Active Optical Sensor (AOS) systems are designed for sensing arable crops to estimate the required amount of nitrogen fertiliser and are well established in intensive arable cropping systems in ...
Optical sensors for variable rate nitrogen application in dairy pastures
(New Zealand Grassland Association, 2017)
Reducing the amount of nitrogen (N) fertiliser applied to dairy pastures down to agronomically optimised levels would have positive economic and environmental results. The ability of commercially available optical sensors ...
Sampling methods for clover species in grazed pastures to diagnose mineral deficiencies
(New Zealand Grassland Association, 2019-11-04)
Diagnosis of clover nutrient status is important for legume-based pasture systems. The protocols for sample collection and setting of nutrient guidelines are ill-defined. This research quantified how nutrient concentrations ...
