Grapia (Apuleia leiocarpa (Vog.) Macbride) is an important native forest species that has been in extinction process. The aim of this study was to evaluate the effect of mineral nitrogen source on growth of grapia seedlings. Five variations in the concentration of N-NO3 - and N-NH4 + (5:0, 4:1, 2,5:2,5, 1:4, and 0:5 mM of N) were tested in an entirely random statistical design with 16 replicates. The experimental unity consisted of a vessel containing 3,0 kg of a Paleudalf soil and two plants…

Crescimento e parâmetros cinéticos de absorção de amônio e nitrato por mudas de Eucalyptus spp submetidas a diferentes relações amônio/nitrato na presença e ausência de fósforo
With the objective of evaluating the effect of exclusive supply of ammonium or nitrate, or both, on the growth of eucalypt seedlings, two experiments were carried out under greenhouse conditions.
Ammonium and nitrate uptake rates and rhizosphere pH in non-mycorrhizal roots of Norway spruce [Picea abies (L.) Karst.]
SummaryRelationships between root zone temperature, concentrations and uptake rates of NH4+and NO3− were studied in non-mycorrhizal roots of 4-year-old Norway spruce under controlled environmental
Sources of N uptake by wheat (Triticum aestivum L.) and N transformations in soil treated with a nitrification inhibitor (nitrapyrin)
Rates of N uptake by spring wheat as ammonium and as nitrate, and rates of nitrification, gross N immobilization and gross N mineralization were measured in a pot experiment during 84 days of growth
Influences of different nitrate to ammonium ratios on chlorosis, cation concentrations and the binding forms of Mg and Ca in needles of Mg-deficient Norway spruce
Effects of Mg deficiency and variations of the NO3-/NH4+-ratio on chlorophyll, mineral nutrient concentrations and the binding forms of Mg and Ca were investigated in current-year, one- and
The influence of nitrogen concentration and ammonium/nitrate ratio on N-uptake, mineral composition and yield of citrus
In short-term water culture experiments with different 15N labeled ammonium or nitrate concentrations, citrus seedlings absorbed NH4+ at a higher rate than NO3−. Maximum NO3− uptake by the whole
Effects of nitrogen fertilization of grapefruit trees on soil acidification and nutrient availability in a Riviera fine sand
Nitrogen (N) fertilizer applied in the NH4+ form results in some degree of soil acidification, which could influence nutrient availability to plants and nutrient losses through leaching. Effects of
Effect of ammonium and nitrate on net photosynthesis, flower formation, growth and yield of eggplants (Solanum melongena L.)
TLDR
The results indicate that vegetative and reproductive growth of eggplants may be manipulated without causing injury to the plants by supplying ammonium nitrogen as long as the age of the plants, carbohydrate reserves of the roots, quantity of ammoniumnitrogen supplied, and pH of the growth medium are favourable.
Response of apple trees to fertigation-induced soil acidification
Summerland McIntosh apple trees (Malus domestica Borkh.)on M.9 rootstock were fertigated for the first 3 yr after planting with all combinations of two rates of N (23.5 and 47.0 g tree−1) and three
Effect of low pH of the root medium on proton release, growth, and nutrient uptake of field beans (Vicia faba)
The effect of low root medium pH on growth and proton release of field beans (Vicia faba L. cv. Kristall) was studied in soil and nutrient solution experiments. Decrease of soil pH due to proton
