This experiment was performed at the Rajiv Gandhi South Campus, Barkachha (BHU) Mirzapur, as a pot culture study, from November 2018 to March 2019–20. is completely randomised design, taking three replications with six treatments, i.e., T1: Control, T2: 5 g kg-1 Hydrogel, T3: 10 T4: 15 T5: 20 and T6: 25 Hydrogel. The soil incubated different doses of hydrogel for 120 days. samples were collecte...

Soil microbial properties are known to exhibit high spatial and temporal variability, which can hinder our understanding of the effects of agricultural management on soil microbial activities, populations and communities. However, if this variability is explicitly considered in soil sampling schemes, experimental results can help us better understand soil microbial properties. In this initial a...

rainfed wheat is the main source of staple food for people in the developing countries. various factors contribute to and affect the production of this crop. the aim followed in the present study was to develop a model to estimate rainfed wheat grain yield as based on physico-chemical properties of the soil. therefore, wheat grain yield and soil physico-chemical properties were separately deter...

some of arid regions problems of iran are saline and sodic soils. in improvement and reclamation of iranian arid rangelands, some foreign species of atriplex had been imported and adapted for many years ago. the most adapted species was atriplex canescens. at the present research, some environmental factors, vegetative characteristics (na, ca, mg and k), soil properties (moisture, ec, ph, solut...

this paper presents a survey on soil pb concentration around sepahanshahr town located in vicinity of isfahan. due to the lack of regulation and environmental education and awareness, sepahanshahr is now a rapid growing residential area suffering from the considerable consequences of poorly regulated mining activities operating in its vicinity. the aim of this study is to explore the spatial st...

Introduction Biogeography describes spatial patterns of diversity and explains why organisms occur in given conditions. While it is well established that the soil microbes largely controlled by edaphic environmental variables, microbiome community prediction from properties has received less attention. In this study, we specifically investigated whether possible to predict composition fungal co...

ground skidding on skid trails affects the physical properties of soil. the objective of this study was to evaluate changes in soil physical properties on skid trails formed due to traffic of metal-tracked skidders with regard to soil bulk density, total porosity, water content and penetration resistance. the studies were implemented on two levels of slope – 20% (sc2) – and three levels of traf...

1. A considerable advance has been made in the study of the fulvic extract of soil organic matter. A new method has been introduced whereby the fulvic extract is separated by a selective adsorption technique into four distinct fractions. 2. These fractions have been obtained from the fulvic extracts from four widely diverse types of soil. 3. A preliminary examination of the chemical properties ...
