Forests affect regional climates, livelihoods and global cycles of water, carbon nitrogen. Anthropogenic activities climatic change forest health national growth. Therefore, developing effective management plans requires understanding the drivers The primary objective this study was to understand long-term effect abiotic factors on growth forests in region. This used Moderate Resolution Imaging Spectroradiometer (MODIS) data for vegetation indices like NDVI EVI NASA's Land Assimilation...
An exponential increase in the human population has drastically reduced length of fallow period (<5 years) widely spread shifting cultivation (Jhum). This increased invasion weeds and decreased soil fertility crop productivity, consequently raised concern food security for local farming communities. The present study was conducted two jhum fallows (FL-10 FL-15) to understand response applications indigenous microbes rock phosphate on levels productivity. results showed greater...
Data are presented for net productivity and nutrient (N, P, Ca, K Na) dynamics in mature (5-year-old, harvested 1982) more recently (in 1986) dry tropical bamboo savannas, on the Vindhyan plateau India.

Abstract Landscape transformation and atmospheric nutrient depositions, important global change drivers, are affecting the vegetation soil properties of natural dry tropical forest derived savanna ecosystems in India. This study assessed effect continuous N P additions for 6 years on size distribution aggregates forest–ecotone–savanna gradient. Addition significantly increased proportion macroaggregates ecotone, whereas same input decreased their savanna. Consequently, stability it The...
Anthropogenic activities are altering the structure and functioning of forests their services to society. However, we know little about degree which such changing health through edge effects in fragmented different regions world. The present study was carried out Minkong Community Reserve Forest Nagaland (North-east India) with aim determine anthropogenic on floristic composition diversity, population structure, biomass carbon (C) stocks core zone (CZ) buffer (BZ) forest. We established 15...
Changes in land use and improper soil management have led to severe degradation around the globe through modification physicochemical biological processes. This study aimed assess properties of different system types. Soil samples (0-15 cm depth) were collected from five uses; Rubber Plantation (RP), Oil Palm (OPP), Bamboo Forest (BF), Fallow Land (FL) Natural (NF) analyzed for bulk density, texture, pH, moisture, carbon, total nitrogen, ammonium, nitrate, microbial biomass respiration. pH...
The study investigates the effect of various existing hill land-use practices on soil quality. types selected for analysis was based common practice in area. Soil samples were collected from different and analysed bulk density (BD), clay, sand, silt content, organic carbon, total nitrogen, available phosphorus, microbial biomass carbon nitrogen (MBC MBN), exchangeable cations. Further, fertility index, evaluation factor Principal Component (PC) Analysis suggested that PC1 accounts maximum...
In the present study we investigated production and decomposition of leaves, branches roots in two moist regenerating tropical forests (5 15 years old; RF-5 RF-15 respectively) a natural forest (NF) north-east India. Total litter input increased during vegetation succession (759, 1089 1284 g m–2 year–1 RF-5, NF respectively), whereas contribution soft decreased sharply. Decomposition over 450 days indicated significant seasonal (P < 0.001) patterns mass loss components, with greater rates...

Nitrogen (N) dynamics during changes in land use patterns tropical forests may profoundly affect fine root and nutrient cycling processes. Variations biomass soil N were assessed developing stands of increasing ages following shifting agriculture Mizoram, Northeast India, comparisons made with a natural forest stand. Concentrations available (NH4-N NO3-N) the proportion NH4-N total increased stand age. The N-mineralization rate also age whilst nitrification relative to ammonification...
This study showed changing patterns in the plant species composition, diversity, and carbon storage potential of different forests along altitudinal gradients (i.e. 100 – 1900 m) Eastern Himalayan India. Different tree, shrub herb were sampled ranging from tropical to temperate through Nested Plot design. In each forest, vegetation sampling was made by establishing a permanent plot 250 m × as per ISRO-GBP/NCP-VCP protocol. Individuals trees ≥10 cm girth at breast height (GBH), shrubs herbs...
ABSTRACT Environmental pollution caused by urbanization, agricultural intensification, and industrialization has led to an increase in the disposal of toxic effluents aquatic environments. Most ecosystems world receive a variety metals (TMs) that exceed capacity water bodies absorb or recycle them, thereby threatening human life. Physicochemical remediation methods encounter problems because high cost, labor input, use chemicals with long residence times later add by‐products. However,...
