I am working on a dataset to derive optimum and sufficiency ranges of leaf nutrient concentrations in olive. I am searching for a reliable reference to compare it with the ranges generated by me.
Ali Mohamed not so clear about what do you mean by " optimum and sufficiency ranges of leaf nutrient concentrations ". Please elaborate?
Yuan-Yeu Yau Sufficiency range of a given nutrient lies between critical deficiency value and an excess or toxic concentration to diagnose plant's nutritional status.
olive tree nutritional status remains based on knowledge gleamed from rain-fed orchards. In the present study, the effect of irrigation level on olive tree nutritional status was investigated in Israel over 4 years on two cultivars and in two locations characterized by differences in soil, tree age, management history, fertilizer application and irrigation water quality. Diagnostic leaves, sampled in July, were evaluated as indicators of nutritional status. Leaf nitrogen concentration was not affected by irrigation level. Leaf phosphorous and potassium concentrations increased with increasing irrigation level. Leaf calcium, manganese and iron tended to decrease with irrigation, while magnesium, sodium and zinc concentrations were not generally affected by irrigation level. Leaf boron and chloride concentrations increased with increasing irrigation when their concentration in irrigation water was relatively high. Leaf nutrient concentration was influenced by cultivar. The results presented in this study emphasize a strong link between irrigation level and the nutritional status of olives for some nutrients and no association for others. These findings should aid in developing distinct fertilization recommendations for fully irrigated olives, different from those developed and used for rain-fed or supplemental-irrigated orchards.
Bryson et al 2014 Plant Analysis Handbook edn 3. lists olives on page 348.
You didn't say which elements you were interested in, but this reference shows the 12 main macro and micro nutrients.
Did you try googling "olive leaf nutrient sufficient" ? I got a number of agricultural extension website with references in them, for example: https://edis.ifas.ufl.edu/ag405 which states: "Olive leaf tissue sufficiency ranges have been determined for locations outside of Florida (Beutel et al. 1983; Sibbett et al. 2005; Vossen 2006; Connell and Vossen 2007; Bryson and Mills 2014)."

Thank you so much Dr. Matthew Wheal
May you please share the page contains the sufficiency ranges in olive in Bryson et al. (2014) as I don't have this book.
Best regards,
50 mature leaves from new growth, production orchard, sampled in Summer. Sufficiency range only given, not deficiency. Location not specified. Variety, fertilizer history, soil type, yield, rainfall, and analytical methods not specified. If, after all those caveats and you trust my transcription abilities:
N% 1.5-2.5
P% 0.1-0.3
K% 0.9-1.2
Ca% 1-2
Mg% 0.2-0.6
S% 0.16-0.23
Fe ppm 35-66
Mn ppm 25-200
B ppm 20-75
Cu ppm 4-9
Zn ppm 25-100
Mo ppm 0.04-0.09
NB some of these values are similar to those in the references suggested by Arvind Singh while others are quite different.
