The present study an attempt has been made to investigate the effect of Seaweed Liquid Fertilizer of Rosenvigea intricata with or without chemical fertilizer on seed germination, growth, yield, pigment content and soil profile of Abelmoschus esculentus was analyzed. The seed germination, shoot length, root length, number of lateral roots, number of leaves, number of vegetables, length of vegeta...

Subsoil compaction can result in unfavourable soil physical conditions and hinder the root growth of maize. The effects of deep tillage and conventional tillage on soil physical properties and root growth of maize were studied during 2010–2011 at two sites (loam at Hebi and clay at Luohe) in central China. The results showed that soil penetration resistance, bulk density, water content and root...

Woody plant encroachment in savannas may alter carbon (C) and nitrogen (N) pools over the longterm, which could have regional or global biogeochemical implications given the widespread encroachment observed in the vast savanna biome. Soil and litter %C and %N were surveyed across four soil types in two encroached, semiarid savanna landscapes in northern South Africa. Litter at sampling points w...

Because a large fraction of the world’s carbon exists in the soil of boreal forests, understanding how soil temperature and moisture affect soil respiration is vital for predicting soil response to climate change. We measured soil respiration and CO2 concentrations within soils of floodplain and upland forests in interior Alaska from 1996 to 1997. At each site, a 0.10-ha-area shelter was constr...

In this paper three transport models are applied to describe the vertical migration process of 137Cs in undisturbed soil. The same experimental data set is used for the calibration of each model. These data were obtained from areas in northeast Italy, where the 137Cs deposition following the Chernobyl accident ranged from 20 to 40 kBq m-2. A diffusion model (called DSF) is presented, which take...

Salt accumulation within the root zone significantly effects plant growth and development in arid semi-arid regions. Today, use of low-quality irrigation water agricultural production is increasing rapidly, because continuous depletion pollution resources. This means more salt transferred to soil profile. It great importance predetermine practices for sustainable crop production. For this purpo...

These differences in temperature and moisture content of the soil profile arising from different types of vegetation cover may have immediate effects on the availability of nutrients (Mitchell 1957) and, on a longer term, on the balance between various directions of soil type development. BANGE,G. G. J., 1953. On the quantitative explanation of stomatal transpiration. Acta Bot. Neerlandica 2: 2...

Soil degradation, including rocky desertification, of the karst regions in China is severe. Karst landscapes are especially sensitive to soil degradation as carbonate rocks are nutrient-poor and easily eroded. Understanding the balance between soil formation and soil erosion is critical for long-term soil sustainability, yet little is known about the initial soil forming processes on karst terr...
