Influence of Different Salinities of Groundwater on Salt Rising and Evaporation of the Soil Surface [PDF]

open access: yesعلوم و مهندسی آبیاری, 2016
Shallow groundwater with different quality could be replaced of irrigation water for crop as a cheap water resource in some semi-arid region of world. But salt rising to the root zone due to capillary flow from shallow groundwater is a limiting factor ...

GEOCHEMICAL MONITORING OF INDUSTRIAL CENTER FOR DEVELOPMENT OF RECREATIONAL AREAS (ON THE EXAMPLE OF KHROMTAU-DON INDUSTRIAL HUB, KAZAKHSTAN) [PDF]

open access: yesGeo Journal of Tourism and Geosites, 2019
Landscape-geochemical assessment of the industrial areas is of particular interest. This paper describes the microelement composition of soils, investigates hydrochemical composition of surface waters and vegetation of the territory.

Application of the Coupled Markov Chain in Soil Liquefaction Potential Evaluation

open access: yesBuildings, 2022
The evaluation of localized soil-liquefaction potential is based primarily on the individual evaluation of the liquefaction potential in each borehole, followed by calculating the liquefaction-potential index between boreholes through Kriging ...

Soil penetration resistance in a rhodic eutrudox affected by machinery traffic and soil water content [PDF]

open access: yesEngenharia Agrícola, 2013
Soil compaction caused by machinery traffic reduces crop yields. This study aimed to evaluate the effects of intensive traffic, and the soil water content, on the soil penetration resistance (PR) of a Rhodic Eutrudox (Distroferric Red Latosol, Brazilian ...

Natural 15N abundance of ammonium and nitrate in soil profiles: New insights into forest ecosystem nitrogen saturation

open access: yesEcosphere, 2022
Assessment of nitrogen (N) saturation of forests is critical to the evaluation of the manner in which ecosystems will respond to current and future global changes such as N deposition. However, quantifying N saturation remains a challenge. We developed a

Long-Term Effects of the Use of Organic Amendments and Crop Rotation on Soil Properties in Southeast Spain

open access: yesAgronomy, 2021
The evolution of soil chemical properties over 20 years was monitored to assess the effects of the change in soil management from a rainfed to an irrigated model and the use of organic amendments and crop rotation.

Yield, nitrogen-use efficiency, and distribution of nitrate-nitrogen in the soil profile as influenced by irrigation and fertilizer nitrogen levels under zero-till wheat in the eastern Indo-Gangetic plains of India

open access: yesFrontiers in Environmental Science, 2022
Due to the introduction of zero-till wheat in the Indo-Gangetic plains (IGP) in India, irrigation and fertilizer nitrogen (N) management needs to be modified from that followed under conventionally tilled fields. A field experiment was conducted to study

Long-Term Organic Substitution Promotes Carbon and Nitrogen Sequestration and Benefit Crop Production in Upland Field

open access: yesAgronomy, 2023
Partial substitution of synthetic nitrogen fertilizer with manure (organic substitution) is highly recommended to minimize environmental risks without compromising crop productivity in intensive agricultural systems.

Conservation tillage for 17 years alters the molecular composition of organic matter in soil profile.

open access: yesScience of the Total Environment, 2020
Conservation tillage is considered as a potential measure to mitigate climate change by sequestering soil organic matter (SOM), however its stabilization mechanisms remain elusive.

CHANGES IN MICROMORPHOMETRIC PARAMETERS OF VOIDS ALONG THE PROFILE OF ZONAL SOILS IN EUROPEAN RUSSIA

open access: yesБюллетень Почвенного института им. В.В. Докучаева, 2015
The soils are distinguished by the presence and the profile distribution pattern of such pedogenic parameters as the organic matter content, available pedofeatures, structural state of the soil mass, etc. They differ in the organization of the pore space
