An intensive review of the literatures was made to access the importance of crop rotation for sustainable agriculture in Nepal. Result shows that an appropriate crop sequences improves soil fertility, reduces fertilizer cost, controls soil erosion, makes environment healthy, increases crop yields and develop sustainable crop production in the long run. Based on the study, identification of loca...

This is a report on a limited evaluation of the low altitude Airborne Visible and Infrared Imaging Spectrometer (AVIRIS) data, for identifying soil salinity and organic matter concentrations in soils using specific spectral bands cited in the literature. This study is part of a larger investigation for using AVIRIS as the image data layer in developing terrain models to simulate the content and...

ISSn: 0967-0335 © IM publications llp 2010 doi: 10.1255/jnirs.883 all rights reserved the measurement of physical and chemical parameters of soil is an important step toward sustainable farming practices, landscaping management and, more generally, the understanding of terrestrial ecosystem processes. Standard soil analytical procedures are often complex, time-consuming, and expensive for many ...

Generally, the evaluation and assessment critical condition of rill formation are useful for a better understanding of soil erosion processes. The inherence characteristics of soils, which have much dynamic variations on the hill-slopes and are affected by rill formation, are the soil critical shear stress and soil erodibility factors. This study aims to assess experimental rill incision thre...

Current bioremediation techniques for petroleum-contaminated soils are designed to remove contaminants as quickly and efficiently as possible, but not necessarily with postremediation soil biological quality as a primary objective. To test a simple postbioremediation technique, we added earthworms (Eisenia fetida) or wheat (Triticum aestivum) straw to petroleum land-farm soil and measured biolo...

To identify effective regulatory methods scheduling with the compromise between the soil desalination and the improvement of tomato quality and yield, a 3-year field experiment was conducted to evaluate and compare the effect of straw mulching and soil structure conditioner and water-retaining agent on greenhouse saline soils, tomato quality, and yield. A higher salt removing rate of 80.72% in ...

Ground improvement has been used on many construction sites to densify granular material, in other word to improve soil properties and reduce potential settlement. This paper evaluates the efficiency of rapid impact compaction (RIC), which is an improvement on the process of deep dynamic compaction, in improving soil properties and controlling soil settlement. In this technique ground improveme...

Although little is known about the behavior of engineered nanomaterials after exposure to terrestrial areas, recent studies indicate that silver nanoparticles (AgNPs) can perturb the soil environment due to their biocidal and catalytic properties. The fundamental evaluation of the environmental fate of AgNPs would be a significant step toward a comprehensive understanding of the harmful effects...
