a number of researches have been performed in the field of elemental analysis of fruitsfrom different areas of iran and there is a vast unstudied area in this field. in this study, seven mineral elements such as na, k, ca, mg, fe, zn and cu in the tree soil, citrus limunum juice of gorgan and iranshahr gardens and citrus limetta juice of gorgan and bandarabas gardens were determined by flame ph...

Fertility is a very old concept and many definitions are available in literature. The first edition of the Dictionnaire de l’Académie Française in 1694 defines fertility as: “quality of that which is fertile; good farming is that which contributes most to the fertility of the soil” (the capacity of a soil to produce a large harvest). A more accurate definition appeared in the 18th century in th...

the aim of this research was to determine the effects of camphorosma monspeliaca species on soil nutrient elements in its habitat. for rangeland, ecological positive or negative effects of plant species on environment must carefully be examined before allowing their plantation in vast areas; on the other hand this species with their special characteristics have special effects on their surround...

In low-nutrient ecosystems such as forests developed on acidic soil, the main limiting factor for plant growth is the availability of soil nutrients. The aim of this study was to investigate in a temperate forest: 1) the influence of the rhizosphere processes on the availability of nutrients and trace elements during one year period and 2) the seasonal evolution of this rhizosphere effect. Bulk...

†Background Plants require at least 14 mineral elements for their nutrition. These include the macronutrients nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg) and sulphur (S) and the micronutrients chlorine (Cl), boron (B), iron (Fe), manganese (Mn), copper (Cu), zinc (Zn), nickel (Ni) and molybdenum (Mo). These are generally obtained from the soil. Crop production is o...

this study was conducted to determine the effects of arbuscular mycorrhizal fungi (glomus mosseae and glomus intraradices) symbiosis on mineral uptake of two pistachio cultivars (pistacia vera cv. qazvini and pistacia vera cv. badami-riz-zarand) grown in the greenhouse under different drought stress levels. drought stress (ds) reduced the mycorrhizal colonization in both cultivars as well as nu...
