In Situ Analysis of Nickel Uptake from Foliar Application in Pecan Using Instrumental µXRF Analysis
Journal of Soil Science and Plant Nutrition, 2021Nickel is an essential element as the cofactor in the enzyme urease, and pecan (Carya illinoinensis (Wangenh.) K. Koch) is known to suffer from commercially important nickel deficiency manifested in "mouse-ear" disease. Foliar application of nickel has been shown to increase foliar nickel concentrations and foliar urease activity and to cure the nickel

Using Foliar Analysis to Classify Nitrogen‐Deficient Sites
Soil Science Society of America Journal, 1984Abstract Discriminant analysis was used to evaluate the efficacy of using foliage N concentration (FN), an adjustment of the foliage N concentration based on stand age (FA), and a nitrogen/phosphorus ratio (N/P) to classify N‐deficient sites. N/P was the superior index of N deficiency.

Experimental Agriculture, 1970
SUMMARYThe literature for the past seventy years describes a variety of methods of sampling tea leaves, in some of which analytical data from samples have been suggested as capable of widespread use as a measure of the nutritional status of tea plantations.

Foliar Analysis as a Diagnostic Technique in Tropical Horticulture
1984A brief history of the development of foliar analysis as a diagnostic technique for horticultural crops is reviewed and discussed. Terminology, together with a basic discussion of the components necessary to operate a successful foliar analysis program for growers, is presented.

Foliar analysis using near infrared reflectance spectroscopy
Canadian Journal of Forest Research, 1988Near infrared reflectance spectroscopy was evaluated as a method for measuring nitrogen and lignin content in foliage of native forest and prairie species. Near infrared reflectance spectra (1590 to 2357 nm) were obtained for 163 samples of dried green leaves and leaf litter from 18 deciduous and 2 coniferous tree species.

Analysis of Foliar Samples of Healthy and Dieback Eucalyptus obliqua
Australian Forestry, 1977SUMMARY Foliar samples were collected and analysed from Eucalyptus obliqua (L'Herit.) at three localities. There were no statistically significant differences between healthy trees and dieback affected trees for foliar N, K, Ca, P, Mg, Na, Cu, Mn, Fe or Al.

Foliar nutrient concentration differences between provenances, and the relationship between foliar nutrient levels and provenance growth was examined in Douglas fir (Pseudotsugamenziesii (Mirb.) Franco) from the coastal region of British Columbia.In the first experiment differences in foliar nutrient concentrations among four provenances of 3-year old

Using Soil and Foliar Analysis to Diagnose the Nutritional Status of Urban Trees
Arboriculture & Urban Forestry, 1995During the past years, increased knowledge about the nutritional status of solitary trees has led to the development of soil and foliar analysis as a tool for the assessment of both chloride damage and nutrient deficiencies in The Netherlands. Data on threshold levels per tree species and element proportions are summarized. This enables the arborist to

The chemistry of some foliar litters and their sequential proximate analysis fractions
Biogeochemistry, 2015Proximate analysis (PA) is widely used to assess foliar, litter, and wood quality. The acid-unhydrolyzable residue (AUR) of PA, originally known as Klason lignin from wood analysis, is often assumed to be entirely lignin-derived, but the AUR of much plant material also includes contributions from condensed tannins (CT) and cutin or suberin.

Floral analysis cannot be considered as an alternative to the foliar diagnosis in the olive
Scientia Horticulturae, 2007Abstract Correlations between macro and micronutrient concentration of olive leaves and those obtained in floral buds at five development stages, were studied in order to evaluate the utility of floral analysis for the diagnosis of the nutritional status of olive orchards. Olive leaves from ‘Arbequina’, ‘Frantoio’, ‘Hojiblanca’, ‘Bella de Espana’ and
