Soil salinization refers to the salinity of the level affecting agricultural and environmental health. Soil salinization usually occurs in arid areas. In these areas, soluble salt ions accumulate in the soil. In these areas where plant growth requires irrigation, the Evaporation and transpiration process leaves salt in the soil.

The purpose of this investigation is to determine whether there is a difference in the effect on the soil microbiology between solarization and occultation, particularly in their application for the termination of a cover crop within a no-till system, and to characterize this difference over a growing season.

Soil salinization is negatively impacting the productivity of coastal forests in parts of the southeastern U.S. To build resilience to this threat, the USDA Southeast Climate Hub developed a manual to help coastal landowners and technical service providers identify potential salinity issues on their forestland and mitigate impacts or adapt management practices, when possible, to keep their ...

Soil salinity is a measure of the minerals and salts that can be dissolved in water. In most cases, the following mineral ions are found in soil-water extract listed in order of importance: Na +, Cl −, Ca + +, SO 4 =, HCO 3 −, K +, Mg + +, NO 3 −. Increased soil salinity has progressive and often profound effects on the structure, water ...

Under drought and soil salinity, plants usually respond to accumulate inorganic and organic osmolytes for adaptation, that would induce changes in energy consumption strategy of plants. Moderate soil salinity would enable plants to lower energy consumption for osmotic adjustment by passively absorbi …

As an alternative, expensive engineering and soil rehabilitation solutions have been proposed, but have generally been considered uneconomical. As of the year 2000, 5,658,000 ha of land (an area larger than The Netherlands) in Australia is saline, and salinity in streams is a growing concern.

Soil Salinity: Causes and Rehabilitation. Where does the salt come from? •Fossil (connate) salt was deposited when sedimentary rocks formed in ancient seas. Where does the salt come from? •Aeolian salt is blown inland from sea spray or salt-bearing sedimentary rock deposits.

Introduction. Salinity has plagued crop production in irrigated regions of the world since the beginning of recorded history. It is particularly common in arid and semi-arid areas where evapotranspiration — evaporation of water from soil combined with transpiration of water from plants — exceeds annual precipitation, and where irrigation is therefore necessary to meet crop water needs.

Soil solarization (SS) was carried out on a glasshouse (0.5 ha area) and a fiber-house (0.25 ha area) during the summer season (2003) at Shahania farm, Arab–Qatari Agricultural Production Company (AQAPCo), Doha, Qatar. Another two identical houses were left without SS as control.

Soil salinity imposes ion toxicity, osmotic stress, nutrient (N, Ca, K, P, Fe, Zn) deficiency and oxidative stress on plants, and thus limits water uptake from soil. Soil salinity significantly reduces plant phosphorus (P) uptake because phosphate ions precipitate with Ca ions (Bano and Fatima, 2009). Some elements, such as sodium, chlorine ...

We conclude the overall approach allows for generations of a digital soil maps (DSMs) of EC e which serve as baseline data that will allow the monitoring of any rehabilitation effort of salt-affected soils according to their actual degree of salinity.

Jakob's and Matia's study, which was finally concluded in 2019, revealed that soil salinity indeed constitutes a major constraint to Maputo's agricultural system. The local causes for salinization are complex; including hydrological mismanagement, urbanisation, sea-level rise and climate change aspects. Farmers are struggling with ...

Resulting issues such as soil crusting, water and wind erosion, soil salinization and soil acidity therefore constitute a major threat. The authors of this book present the main processes and factors of soil degradation, different ways to prevent it and methods of rehabilitation.

ABSTRACT: Soil salinization is one of the major causes of land degradation. In Senegal, this phenomenon continues to grow, making soils unsuitable for agriculture. To rehabilitate salty lands, one of the recommended strategies is the use of salt-tolerant plants.

Soil salinity control relates to controlling the problem of soil salinity and reclaiming salinized agricultural land.. The aim of soil salinity control is to prevent soil degradation by salination and reclaim already salty (saline) soils. Soil reclamation is also called soil improvement, rehabilitation, remediation, recuperation, or amelioration.

We examined soil rehabilitation techniques in the context of improving tree growth, rooting depth, stormwater capture, and carbon sequestration in soils damaged by land development. There's a lot that's known about soil restoration, but little …

Soil and groundwater salinity has emerged as the most significant agricultural problem facing the Sultanate of Oman. Scant rainfall, coupled with high temperature, is always conducive to the accumulation of salts in soils. These conditions are predominant in Oman. Secondary soil salinity has increased at a very rapid rate due to the persistent use of saline groundwater, which, over time, has ...

Soil Quality and Soil Productivity in Africa Introduction. More than four decades of research and development work in Africa have not resulted in the 3-5 % annual increase in agricultural growth (Badiane and Delgado, 1995) that is necessary for most African countries to ensure sustainability of agriculture and the promise of food security in the next decade.

Salinization of Soils Paper Having food that is accessible to humans in everyday life is something that gets overlooked of how fortunate we are to have different options of food. Many places in the world have people suffering and starving for food. Food is grown from soil and the importance of soil health is critical to growing healthy foods. Something that many don't know is that soil ...

The Soil Quality Test Kit Guide (prepared by NRCS and ARS) is an 82-page booklet containing procedures for 12 on-farm tests, an interpretive section for each test, data recording sheets, and a section on how to build the kit. Chapter 5 includes an electrical conductivity test for salinity. See Section II for salt tolerance of selected crops.

Land rehabilitation as a part of environmental remediation is the process of returning the land in a given area to some degree of its former state, after some process (industry, natural disasters, etc.) has resulted in its damage.Many projects and developments will result in the land becoming degraded, for example mining, farming and forestry

Increasing soil salinization is the major cause of reduced natural biodiversity as well as farm and livestock productivity in Ethiopia and South Sudan. With 11 million hectares of salt-affected soils, Ethiopia stands first in Africa in the extent of area of salt-affected soils due to human-induced and natural causes. These areas are mainly concentrated in the Rift Valley, Awash and Wabi ...

The impact from soil salinization has been of primary concern to our country. The Land Development Department has been operating the Prevention of Soil Salinization and Rehabilitation Plan. The Reforestation Project was implemented in an area of 2000 ha of Nakhon Ratchasima province in the north-east region from 1996-1999. The

Conductivity values (for a soil saturation extract) may vary from 0.1dS/m (low salinity hazard) to 9.0dS/m (very high). The conversions in table 1 are based on the estimate that 670mg of a mixture of salts in 1L of water will have a conductivity of approximately 1dS/m.

"Rehabilitation efforts should not attempt to restore the ecosystem to some particular condition; they should rather be aimed at "kick-starting" the process of natural succession and healing." 1. A PREAMBLE TO SOIL EROSION CONTROL Ecological rehabilitation is a great deal more than a technical management challenge.

Rehabilitation and Management of Salt-affected Soils to Improve Agricultural Productivity (RAMSAP) in Ethiopia and South Sudan. Increasing salinity remains a challenge to sustainability of irrigated agriculture in Ethiopia and South Sudan as it reduces natural biodiversity as …

Climate-driven soil salinization, driven by a combination of altered rainfall patterns, precipitation rates, and rising sea-level, is a major problem for both natural and agricultural systems and exacerbates salinity issues from intensive land-usage (for example, irrigation water and the groundwater table) (Eswar et al., 2021).

accumulate in the soil. Salinization is a resource concern because excess salts hinder the growth of crops by limiting their ability to take up water. Salinization may occur naturally or because of conditions resulting from management practices. Any process that affects the soil-water balance may affect the

As a result of rising water tables in irrigated and non-irrigated areas or the use of saline water supplies—salinity can have significant impacts on the following aspects.. Agricultural production. Water moves into plant roots by a process known as osmosis, which is controlled by the level of salts in the soil water and in the water contained in the plant.
