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.

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.

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.

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).

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.

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.

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.

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.

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.

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.
