Agricultural residues are the largest potential near term source of biomass for bioenergy production. Sustainable use of agricultural residues for bioenergy production requires consideration of the important role that residues play in maintaining soil health and productivity. Innovation equipment designs for residue harvesting systems can help economically collect agricultural residues while mi...

The field-scale application of apparent soil electrical conductivity (ECa) to agriculture has its origin in the measurement of soil salinity, which is an arid-zone problem associated with irrigated agricultural land and with areas having shallow water tables. Apparent soil electrical conductivity is influenced by a combination of physico-chemical properties including soluble salts, clay content...

  The main purpose of this research is review of principles, concepts, problems and solutions of soil ethic. In this research by descriptive method and Delphi technique was used for identifying soil ethical concepts, soil ethical principles, problems and difficulties of soil ethics in Iran and al around the world and suggestions for improvement of soil ethics in Iran. The population of this re...

Different agricultural practices may have substantial impacts on crop physiology and yield. However, it is still not entirely clear how multiple agricultural practices such as tillage, biochar and different nutrient applications could influence corn physiology and yield. We conducted a three-year field experiment to study the responses of corn physiology, yield, and soil respiration to six diff...

C. Alister, M. Araya, and M. Kogan. 2011. Effects of physicochemical soil properties of five agricultural soils on herbicide soil adsorption and leaching. Cien. Inv. Agr. 38(2): 243-251. Once pesticides reach the soil, there are several factors that affect their soil behavior. To identify the principal soil and herbicide properties that control their adsorption and leaching, a study of five Chi...

The state of soil Being the largest country in the world as to its territory, Russia has not managed to escape the problem of land loss in the face of challenges connected with modern social development. One such problem relates to the loss of the fertile layer of the land surface known as soil. The causes of these negative processes seem to be widely known and similar in many countries. Howeve...

abstract in this study the effects of land use changes from pasturelands to croplands on soil microbiological and biochemical properties were studied in kangaver, dehno and soltanye regions. composite soil samples from 0-20 and 20-40 cm depths of pasture and cultivated lands were taken from kangaver, dehno and soltanye regions, and soil microbial respiration, microbial biomass c and n, and urea...

soil quality is the most suitable index to an assessment of the stability of terrestrial ecosystems, especially agro-ecosystems. to determine the effects of agricultural practices on soil organic matter, species richness and abundance of soil invertebrates, a study was conducted in three regions of razavi and northern khorasan provinces, iran. soil were taken from in each winter wheat field of ...

Agricultural soil is typically an important component of urban ecosystems, contributing directly or indirectly to the general quality of human life. To understand which factors influence metal accumulation in agricultural soils in urban ecosystems is becoming increasingly important. Land use, soil type and urbanization indicators all account for considerable differences in metal accumulation in...
