Modelling the Effects of Soil Conditions on Olive Productivity in Mediterranean Hilly Areas

Table 5

Regressions between olive leaf primary macronutrient concentrations and soil depth . Coefficients of determination and statistical significance are also presented. Models are sorted in descending order of .

Leaf minerals vs. soil depth	Model		<
Leaf K concentration		0.12	0.019
Leaf P concentration		0.03	0.21
Leaf N concentration		0.01	0.50
