Karst ecosystems are fragile and are in many regions degraded by anthropogenic activities. Current management of degraded karst areas focuses on aboveground vegetation succession or recovery and aims at establishing a forest ecosystem. Whether progressive succession of vegetation in karst areas is accompanied by establishment of soil biota is poorly understood. In the present study, soil microb...
Iron oxide-coated strips (Pi) can serve as a sink to continuously remove P from solution. In this way, probably, P extraction is analogous to P absorption by plant root. The objective of this study was to evaluate the iron oxide-coated paper strips to estimate the availability of soil P of corn (Zea mays) grown under greenhouse conditions in some soils of Hamadan Province. Sixteen soil samples ...
The Present Study was undertaken to assess Depth Wise Studies of Physico-Chemical Properties Soil under Different Land Use System main campus university at Acharya Narendra Deva University Agriculture and Technology, Kumarganj, Ayodhya (U.P.) during 2018-2019.
 samples were collected RWCS (Rice-Wheat cropping system), LBCS (Legume based VBCS (Vegetable System).The land use systems selected...
Co-composting of raw manure with other organic sources has recently gained the attention scientific community. In present study, and manures enriched humic substances (Humac) or biochar were co-composted to improve their physico-chemical properties. We conducted an experiment including variants consisting soil amended (M), + Humac (M H), B), unamended (control). Soil physico-chemical, biologica...
Urban green spaces provide ecosystem properties fundamental to the provision of ecosystem services, such as the sequestration of carbon and nutrients and serving as a reservoir for organic matter. Although, urban vegetation influences soil physico-chemical properties, it remains unknown whether ecosystem properties depend on plant species portfolios. We tested the influence of three common func...
Although numerous studies have demonstrated the key role of bacterial diversity in soil functions and ecosystem services, little is known about the variations and determinants of such diversity on a nationwide scale. The overall objectives of this study were i) to describe the bacterial taxonomic richness variations across France, ii) to identify the ecological processes (i.e. selection by the ...
Very few studies have addressed the phylogenetic diversity of fungi from Northeast India under the Eastern Himalayan range. In the present study, an attempt has been made to study the phylogenetic diversity of culturable soil fungi along the altitudinal gradients of eastern Himalayas. Soil samples from 24 m above sea level to 2,000 m above sea level altitudes of North-East India were collected ...
Studies to the feasibility to characterize soil types by soil microbiological and biochemical analysis focus on the existence of microbial and biochemical characteristics distinctive to individual soil types. Many authors have attempted to elucidate relationships between microbiological and physico-chemical properties of different soil types (DUTZLER-FRANZ, 1977a, b; KHAZIYEV and KHABIROV, 1983...
