Nitrogen Foliar Feeding has Advantages

An examination of the advantages and affects of nitrogen (N) foliar feeding on the quality of nursery plants. Topics include which N formulation is best, fall applications, advantages of fall foliar nitrogen, and spring applications.

Nutrient Uptake and Distribution in a Mature 'Pinot noir' Vineyard

Report on a study undertaken to investigate nutrient uptake and distribution of mature Vitis vinifera L. 'Pinot noir' vines (23 to 24 years old) grown without irrigation in a region with low summer rainfall common to western Oregon vineyards.

Put Mycorrhizae to use

A discussion about mycorrhizae, a natural fungi that can greatly improve plants' nutrient and water uptake. The authors specifically discuss why mycorrhizae are important, whether or not they are needed, necessary materials, and when and how to use mycorrhizae.

Phosphorus Supply Alters Tuber Composition, Flower Production, and Mycorrhizal Responsiveness of Container-Grown Hybrid Zandtedeschia

The purpose of this study was to determine if arbuscular mycorrhizal fungi (AMF) inoculation influences plant development, reproduction (vegetative and floral), and/ or tuber quality in calla lily (Zantedeschia spp. and hybrids).

Changes in Polyamine Content and Localization of Pinus sylvestris ADC and Suillus variegatus ODC mRNA transcripts During the Formation of Mycorrhizal Interaction in an In Vitro Cultivation System

Research report detailing a study conducted on the involvement of polyamines (PAs) in the interaction between Pinus sylvestris L. seedlings and an ectomycorrhizal fungus Suillus variegatus (Swatz: Fr.) O. Kunze in an in vitro cultivation system.

Methods of Nitrogen Application in Summer Affects Plant Growth and Nitrogen Uptake in Autumn in Young Fuji/M.26 Apple Trees

The intent of this study was to determine the (1) effect of soil versus foliar nitrogen (N) applications during the summer on tree growth, and (2) effect of soil versus foliar N applications during summer on N uptake in the autumn in young apple trees.

Timing of Urea Application Affects Leaf and Root N Uptake in Young Fuji/M.9 Apple Trees

The ambitions of the study were to compare the effects of different timings of nitrogen (N) application on leaf and root N uptake, and to determine the distribution of N absorbed by leaves and roots at different times in young Fuji/M.9 apple trees.

Inoculation with Ericoid Mycorrhizal Fungi Alters Fertilizer Use of Highbush Blueberry Cultivars

This study investigates the potential role EMF plays in container-grown blueberry production. Specifically, it was determined whether growth and nutrition of highbush blueberry is influenced by inoculation with various EMF isolates, and whether the response to EMF is altered by the type of fertilizer used.

Isolate-specific Rooting Responses of Leucothoe fontanesiana Cuttings to Inoculation with Ericoid Mycorrhizal Fungi

Nursery Crops
The intent of the study was to determine whether an EMF inoculum, added to the rooting substrate during cutting propagation, can alter root production by L. fontanesiana, and whether responses to inoculation depend on the EMF isolate used as inoculum.

Frequency and Intensity of Root Colonization by Ericoid Mycorrhizal Fungi in Nursery Production of Blueberry Plants

Nursery Crops
A report on a survey conducted on commercial nursery plants produced from tissue culture and cuttings to determine when or if ericoid mycorrhizal fungi (EMF) colonize blueberry plants under nursery cultural methods.
