a three-year field experiment was conducted under conditions of luvic chernozem soil. diversified nitrogen fertilization with 0, 60, 120, and 180 kg n ha-1, and microbial preparations improving soil properties were applied to potatoes, cv. ‘satina’, cultivation. n–no3 concentration in the soil profile (0–0.9 m) in autumn after potato harvesting fluctuated from 28 kg n ha-1 in the n0 treatment t...

To effectively manage soil fertility, knowledge is needed of how a crop uses nutrients from fertilizer applied to the soil. Soil quality is a combination of biological, chemical and physical properties and is hard to assess directly because of collective and multiple functional effects. In this paper, we focus on the application of these concepts to agriculture. We define the baseline fertility...

aeolian process and subsequently soil erosion are key factors in dryland environments. such phenomena are related not only to geoecological factors (lithology, topography, and climatology) but also to land-use and plant cover changes. formation of new sand dunes in damghan explains the development of human activities over the past. the aim of this study is to explain the land use changes and th...

introduction the global climate is changing and, despite efforts to reduce greenhouse gas emissions, weather variation is inevitable. meanwhile, agriculture as a major water consumer will require adaptation to these variations, along with other challenges, to guarantee its persistence and sustainability. given the arid and semi-arid climate of iran, water, as a main limiting factor for agricult...

Fungi of the recently defined order Sebacinales (Basidiomycota) are involved in a wide spectrum of mutualistic symbioses (including mycorrhizae) with various plants, thereby exhibiting a unique potential for biocontrol strategies. The axenically cultivable root endophyte Piriformospora indica is a model organism of this fungal order. It is able to increase biomass and grain yield of crop plants...
