Colonization of life on Surtsey has been observed systematically since the formation of the island 50 years ago. Although the first colonisers were prokaryotes, such as bacteria and blue–green algae, most studies have been focused on the settlement of plants and animals but less on microbial succession. To explore microbial colonization in diverse soils and the influence of associated vegetatio...

The effects of soil continuous cultivation and texture on some its properties, electrical conductivity, total porosity, calcium carbonate content penetration resistance. Six samples material for a layer 0-30 cm were collected from three different sites are Clay, Loam Loamy Sand in Basra Governorate Abi al-Khasib, Karma Zubair. Three these represented the treatment cultivation, planted with alfa...

knowledge of the phosphorus (p) forms is essential for understanding the behavior of phosphorus. the aim of this study was to investigate the effect of wheat cultivation on different inorganic p forms of soil. a greenhouse factorial experiment in a completely randomized design was carried out with three replications in 20 soil types and plantation at two levels (with and without plantation). th...

Lolium perenne L. commonly known as “ray grass” is a temperate grass species used pasture for livestock. perennen belongs to family Poaceae and perennial herb. It has great economic importance owing its suitability forage grass. cultivated in fields feed However, current study focuses on uncultivated Ray widely distributed fields, mostly found moist places, banks of stream, pastures etc. Farmer...

Alterations of soil characteristics frequently accompany adaptations pristine areas to different land uses, and these shifts have an impact on the overall ecosystem. Soil carbon stores atmospheric CO2 emissions are directly affected by those in farming management usage. To comprehend mechanisms involved pool, this study was conducted a subtropical region considering six contiguous uses; pasture...

Background- Soil organic carbon serves as potential indicator of the soil quality which is influenced by changes in management practices. The conversion natural ecosystem anthropogenic activities resulted decline SOC. So, this study was conducted to assess indices and understand dynamics develop strategies for enhancing C pool soil. Methods- present major land use systems Mayiladuthurai distric...
