Agroecosystem nitrogen (N) loss produces greenhouse gases, induces eutrophication, and is costly for farmers; therefore, conservation agricultural management practices aimed at reducing N loss are increasingly adopted. However, the ecosystem consequences of these practices have not been well-studied. We quantified N loss via leaching, NH3 volatilization, N2O emissions, and N retention in plant ...

Nitrogen-mineralization rates are needed to accurately determine N fertilization requirements to meet plant needs while minimizing environmental contamination. A spring wheat (Triticum aestivum L.)-fallow (SW-F) system was compared with a spring wheat-winter wheat-sunflower (Helianthus annuus L.) (SW-WW-SF) system on a Temvik-Wilton silt loam (finc-silty, mixed Tj pic and Pachic Haploborolls) a...

BACKGROUND Survivorship care plans (SCPs) are intended to facilitate communication and coordination between patients, oncologists, and primary care providers. Most SCP initiatives have focused on oncology providers initiating the SCP process, but time and resource barriers have limited uptake. OBJECTIVE This trial compares the feasibility and value of 2 Web-based SCP tools: provider-initiated...

Objective: The main purpose of this research is review of principles, concepts, problems and solutions of soil ethic. Methods: 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 popu...

A double hurdle statistical analysis of 250 farms in the Tigray region of Ethiopia reveals different causal factors for soil conservation adoption versus intensity of use. Farmers’ reasons for adopting soil conservation measures vary sharply between stone terraces and soil bunds. Long-term investments in stone terraces were associated with secure land tenure, labour availability, proximity to t...

The knowledge and characterization of aggregate stability are relevant to select adequate management avoid its degradation. Thus, this study aimed characterize the spatial variability in cohesive soils under crop conservation systems. experiment was performed two different areas soybean production: no-tillage System (NTS) livestock farming integration system (LFI), In each production area, a sa...

Intensive agriculture causes land degradation and other environmental problems, such as pollution, soil erosion, fertility loss, biodiversity decline, greenhouse gas (GHG) emissions, which exacerbate climate change. Sustainable agricultural practices, reduced tillage, growing cover crops, implementing crop residue retention measures, have been proposed cost-effective solutions that can address ...

Soil erosion is one of several major deterioration processes which result in soil degradation and declining agricultural productivity Ethiopia due to the dense population, high livestock density, intensive crop production area. water conservation practices are mechanisms used reduce associated nutrient loss, reducing risk production. Therefore, review focuses on importance properties Ethiopia. ...
