Two different soils

Ebook "The bearing capacity of building foundations" describes the different ways of ultimate bearing capacity determination of building foundations. This four-chapter book considers the effect of a horizontal force acting on a foundation. It also examines a situation where, beneath the foundation level in the zone of influence of the foundation there are two layers of soil, including the case where the second, lower layer is formed by incompressible rock.

Ebook "Phytoremediation and biofortification: Two sides of one coin" is a valuable resource to students, technicians, and academics who are interested in the treatment of environmental problems (bioremediation) through the use of plants, and in the field of biofortification. This book shows how, despite having different goals, both phytoremediation and biofortification technologies can be closely connected as they are both based on the phytoextraction process that involves plant uptake, accumulation, and transformation of nutrient elements from soil.

Vietnam and Cambodia have same significant strategic benefits in the Mekong Delta. And, the trans-boundary dimension and respective management issues are highline agenda of them. Although, the economic development of each country is different in the boundary region of Mekong Delta, two countries have a same problems as from the natural hazard (including flood, drought, acid sulphate soils, and saltwater intrusion) to the impact of upstream development, a myriad of flood controlling infrastructure, and the implications of climate change.

The total bacterial population in the rhizosphere of ten melon and two snake melon genotypes was significantly 59 to 68% higher than control soil. For most tested genotypes, a significant increase in the culturable rhizospheric actinomycetes, about 28.5 to 92.6%, was recorded comparatively to control soil. Fungal population counts in the rhizosphere of tested genotypes were significantly comparable to control.

Polymer blending as an efficient method for blending at least two polymers is usually used to create new materials with desirable physical properties. This article focuses on the biodegradability evaluation of polypropylene (PP) fibers modified with disposable recycled poly(lactic acid) (r-PLA) plastic flakes. Biodegradable modified PP fibers containing 30% r-PLA were prepared by melt spinning process and evaluated with different methods of biodegradation assays.

In this study, with the aim of determining and assessing the influence of several culture conditions on the ligninolytic enzyme (LiP, MnP, and Lac) activity of bacteria, five lignin-degrading bacteria strains were isolated from two different soil samples and cultured on minimum salt medium agar containing alkaline lignin (MSML agar). Among the five isolated strains, DL1 and X3 expressed strong and stable ligninase enzyme activity at various temperature levels (30C, 37C, 50C, and 60C) and were selected for further study.

Biochar is a carbon rich substance obtained from thermal decomposition plant biomass through the process of pyrolysis. The special characteristics of the biochar are its effectiveness in retaining most of the nutrients and maintaining them available to plants. The present field experiment was therefore conducted to investigate the effect of biochar application on nutrients concentration and uptake by soybean in acidic soils. Biochar produced from coconut shell was applied at the rates of 5, 7.5 and 10 t ha-1with two rates of recommended lime (100 and 50%).

The phenomenon of stay-green and root traits are most important in drought tolerance breeding. The present investigation was conducted to identify the drought resistant staygreen genotypes with desirable root traits which are essential to extract moisture from deeper layers of the soil under drought conditions. Seven stay-green genotypes along with three non-staygreen checks were evaluated for root traits in PVP pipes with different soil moisture regimes under Factorial RBD design with two replications.

Two consecutive field experiments after rice crop were conducted during 2011-12 and 2012-13 in the Crop Research Centre, of Sardar Vallabhbhai Patel University of Agriculture and Technology, Uttar Pradesh. Ten different treatments were implied to evaluate the residual effect of vermicompost and applied inorganic fertilizers on wheat crop. Significantly taller plants than T2 during both the years were measured in those treatments where 4 ton vermicompost was applied in rice.

The literal meaning of Hysteresis is to be lagged behind. In soil system, it is evident that the two soil moisture characteristic curves do not follow the exact same reversible path. As a result a hysteretic behaviour is experienced. Several causes may be attributed like non uniformity of pores, contact angle difference, entrapped air in pore space and the swelling and shrinking property of soil. To predict the hysteretic behaviour, several models defining the character were also suggested like Conceptual models and Empirical models.

In India, area under cultivation is about 159.7 million ha. 68% of the total net sown area comes under dry land cultivation, spread over 177 districts. As farmers turn increasingly to multiple cropping systems to boost their incomes and meet increased demand for their produce, the time available for seedbed preparation has decreased considerably.

This article describes the difference of morphological and structural characteristics of the roots of Calamus plants growing in those two relatively distinct environments. The result showed that the roots of Calamus express the general characteristics of monocots; there was no secondary growth; the vasculation of the pillar demonstrated many differences to that of a general monocot.
