land use may be regarded as one of the most important factors affecting theenvironment with respect to human activities. so far, destroying the rangelands andchanging them into the waste lands and poor rangelands has been proposed as the mostsignificant variations of land use done by human beings. this paper has been conducted toevaluate the variations of vegetation percentage and land uses in ...
Abstract Background Soil quality, which can be inferred using indicators that interact synergistically, is affected by land use types and agricultural management practices. This study assessed the status of soil quality under three adjacent uses (cultivated, grazing, fallow) in Kersa subwatershed (622 ha). samples were collected from surface (0–20 cm depth) identified with replications paramete...
Micro-organism populations on the leaf surface can be an indicator of environmental health in orchards. A method was developed to detect changes in these populations in apple orchards. Firstly, the variation within orchards was investigated by sampling leaves from seven locations within four trees in spring and autumn. The population density and species richness of micro-organisms when grown on...
The fallow agricultural soils of Northwest Russia represent an evolutionary model the development ecosystem components in time and space with multidirectional dynamics agrogenic impact during long history land development. There has been both large-scale uncontrolled conversion arable lands to a state along their removal recent times. All this led formation chrono-series different-age varying d...
In the Congo Basin, smallholder farmers practice slash-and-burn shifting cultivation. Yet, deliberate burning might no longer be sustainable under reduced fallow scenarios. We synthesized data from the Forest Margins Benchmark Area (FMBA), comprising 1.54 million hectares (ha), in southern Cameroon and assessed the impact of fire exclusion on yield, labor inputs, soil fertility, ecosystem carbo...
An analysis of the species composition vegetation on fallow plots different duration and virgin lands made it possible to conclude that succession state with increasing age. Comparison zootechnical parameters hay from experimental agrocenoses average content fat, ash fiber for variants is 17.0%, 9.8% 7.7%, respectively, higher than in variant. Analysis chemical showed concentrations nitrogen, c...
The flora of willow (Salix viminalis L.) plantations consists various plant groups, including plants related to arable land, called segetal plants. Knowledge this is important for maintaining biodiversity in agroecosystems. aim the study was assess central Poland, depending on land use before establishment (arable or fallow) and age plantations. Moreover, also check presence invasive, medicinal...
This study explores the influence of land-use and land cover (LULC) changes on temperature over North India (NI) North-Eastern (NEI) during 1981–2006 by subtracting reanalysis from observed (observation minus (OMR) method). The normalized difference vegetation index (NDVI) data AVHRR satellite for period were analyzed to understand type LULC this their linkage with change two regions. results O...
The seedlings and saplings plant stage determines the successional stages in secondary forest establishment process. estimation on aboveground biomass (AGB) of seedling sapling plants is needed to describe undergrowth's contribution forest. This study's objective was develop allometric equations for accurate AGB for seedlings-saplings 10 20 years old forests. study carried out at sites with ...
Many studies have investigated the benefits of agri-environmental schemes, such as organic farming, on biodiversity conservation in annual systems, but their effectiveness in perennial systems is less well understood, particularly in bird communities in temperate regions of Asia. This study examined the effects of organic farming practices on species richness and abundance of breeding birds in ...
