Within-stand nutrient cycling is dependent on many factors, including primary productivity, nutrient-use efficiency, nutrient resorption, sclerophylly, decomposition, nutritional quality of plant tissue, and allocation to defense. The efficiency of these plantmediated processes depends on nutrient availability in the environment and inherent functional properties of plants. However, little is k...

India is the largest producer of rice (Oryza sativa L.) next to China in the world. Rice cultivation is a huge water demanding enterprise. In recent years, water table has depleted at a very rapid rate throughout the globe, thus, posing alarming threats and limiting the scope for cultivation of high water consuming crops especially rice. Challenges in maintaining the sustainability of rice farm...

abstract- as the world's population has grown and become more urban and affluent, waste production has raised drastically. wastewater reuse has been identified as a way to alleviate water scarcity and improve crop productivity and environmental sustainability. to address the issue, a soil column experiment was carried out in a 3 × 3 factorial randomized block design including three treatments o...

The microelectronics industry is focused on increasing chip complexity, improving the density of electron carriers, and decreasing the dimensions of the interconnects into the sub-0.25 mum regime while maintaining high aspect ratios. Water-based chemical mechanical planarization or polishing (CMP) faces several technical and environmental challenges. Condensed CO2 has significant potential for ...

the main objective in production of any rainfed crop, including barley farming is to increase water productivity along with stability in the production of the rainfed crop through improvement of the agronomic management including limited single irrigation (si) and sowing date (sd). in order to determine optimal si management and limited water allocation scenarios, a field experiment was conduct...

The importance of the choice well exploitation methods is analyzed. Mechanical applicable in carbonate reservoirs are discussed. To maintain efficiency field development, it important to productivity wells at planned level throughout entire production period by increasing their productivity. Productivity increase, skin effect reduction achieved with help acid treatment, main principle which roc...

Introduction: This study aimed to evaluate the most important public environmental issues and concerns, the public knowledge about these issues, as well as the quality of environmental issues in Rafsanjan, Iran. Materials and Methods: In this descriptive-analytical study, 384 people were randomly selected from Rafsanjan City and their public environmental issues and concerns were evaluated. Th...

Nutritional and environmental factors have been shown to cause epigenetic changes that influence characteristics of the offspring throughout life. In livestock, small differences in nutrition during gestation may alter lifetime production efficiency of offspring. Therefore, the potential for fetal programing should be considered when determining supplemental feeding strategies during gestation....

Abstract The use of inorganic nitrogen (N) fertilizers has increased drastically to meet the food requirements world's growing population. However, excessive chemical fertilizer caused a series soil and environmental problems, such as hardening, lower efficiency (NUE), nitrate pollution water sources, nitrous oxide emissions, etc. In this review, we aimed elaborate discuss role engineered bioch...
