Mature forest ecosystems are the most considerable reservoir of organic carbon (OC) among terrestrial ecosystems. The effect of soil type on aboveground OC stocks and their annual increases (AI) of ov...
This study evaluated the influence of the arbuscular mycorrhizal fungi (AMF) inoculation of leek (Allium porrum L.) on the leaching of ammonia and nitrate nitrogen from the experimental pots filled wi...
The study analyses the chemical properties of the soil in open-canopy beech stands in relation to the predominant species of ground vegetation. A hypothesis is examined whether the predominant ground ...
Three hundred and seventy-three steers (approximately 7 mo of age and 24719.4 kg) were utilized to determine the effects of trace mineral (TM) source and growth implants on trace mineral statu...
The objective of this work is to evaluate the effect of alginite on the growth parameters of seedlings of Douglas-fir, Scots pine and line mixture of pedunculate oak, red oak and Norway maple (broad...
The aim of the study was to evaluate egg shell quality characteristics, mineral content in the egg shell, and serum mineral concentration during the egg formation process as influenced by oviposition ...
The results showed that the concentration of IgG was increased in the plasma of pigs fed the PPEs supplemented diets being significantly higher (P < 0.05) in the case of dietary sodium alginate su...
Changes in the volumetric bone mineral density (vBMD) and bone mineral content (BMC) of tibiotarsal bones of growing turkeys as affected by birds’ age, sex, and within-the-bone location, respectivel...
A model of postmenopausal osteoporosis was used in the study. 107 days after ovariectomy the animals were subcutaneously applied 1.0 IU PRL/kg BM or 1.0 IU calcitonin/kg BM for 7 days in single doses....
During pregnancy, the maternal body undergoes significant physiological changes. The present study assessed the changes on calcium (Ca), phosphorus (P), magnesium (Mg), sodium (Na) and potassium (K) m...
Relic karstic soils in nine localities in the Dinaric Karst in Slovenia, five localities in the Moravian Karst and four localities in the Bohemian Karst were sampled for soil scientific, mineralogical...
The present study investigated the effect of a moderate substitution of inorganic mineral sources with chelated mineral sources from four weeks prior to parturition throughout lactation on sow and lit...
Based on a greenhouse experiment, we evaluated nitrogen availability in the surface mineral layer of soil under various deciduous forest stands by analysing the following soil characteristics: total o...
Simultaneous salinity and boron (B) excess often occur due to irrigation with water containing high levels of salts, including B. The effects of excess of NaCl and B in the nutrient solution on some a...
Mineral nutrition represents the uptake, transport, metabolism and utilization of nutrients by the forest stand. These processes influence all physiological functions of trees. A specific minimum amou...
