Spatial variability in pH and key soil nutrients: is this an opportunity to increase fertiliser and lime-use efficiency in grazing systems?
Abstract. Nutrient-use efficiency is a key issue for grazing systems in Australia. Spatial variability in soil pH and nutrients at the sub-paddock scale may affect the efficiency of utilisation of,… Expand

Discrimination of species composition types of a grazed pasture landscape using Sentinel-1 and Sentinel-2 data
TLDR
The combination of S1 and S2 features elicited the highest accuracy estimates of the classifiers in that the KNN classifier recorded 0.96 and 0.89 while RF and SVM produced 0.93 and0.89, respectively. Expand
