Computational analysis of the effects of light gradients and neighbouring species on foliar nitrogen

open access: yesEcological Informatics, 2018
Abstract Foliar nitrogen is one of the key traits determining the photosynthetic capacity of trees. It is influenced by many environmental factors that are often confounded with the photosynthetic photon flux density (PPFD), which alone strongly modifies the nitrogen content and other foliar traits.

IMPACT OF CULTIVAR ON THE NUTRITIONAL STATUS OF THE YOUNG APRICOT TREES (Prunus armeniaca L.)

open access: yesActa Scientiarum Polonorum: Hortorum Cultus, 2012
Mineral nutrition of apricot is very specific and depends on different factors such as soil fertility, soil pH, weather conditions, cultivars, rootstocks, fertilizers, age of trees etc. For these reasons, during 2008 and 2009 we evaluate nutrient status

DRIS: concepts and applications on nutritional diagnosis in fruit crops

open access: yesScientia Agricola, 2004
Nutrition and fertilization are important factors in determining fruit yield and fruit quality. There are several methods for plant nutritional status diagnosis, among them, two are relevant and named as Sufficiency Range Approach (SRA) and Diagnosis and
