Prospects of desalination for irrigation water in the Sultanate of Oman
The most limiting factor for the agricultural sector in the Sultanate of Oman is a lack of water, and security of supply in terms of both quantity and quality. Salinization of both soils and groundwater systems along the coastal strip of Al-Batinah has placed a substantial burden on farmers regarding crop selection and, therefore, farm profitability. Desalination of brackish and seawaters ...

A time domain transmission sensor with TDR performance characteristics
Abstract Time domain reflectometry (TDR) has become a standard method for determining water content in soils and porous media. However, the cost of instrumentation and the level of user ability required often limit its application, especially for agricultural and urban soil water management. The objective of this paper is to report on a new, lower cost time domain transmission (TDT) sensor and to ...

Application of intelligent soil sensor in agricultural production
Abstract: With the rapid development of precision agriculture, the application of smart soil sensors has become an important part of modern agricultural production. Smart soil sensors can measure the physical and chemical properties of soil in real time, such as temperature, humidity, pH value, salinity, nutrient content, etc., to provide scientific and accurate data support for farmers to carry ...

Salinization/sodification of soil and physiological dynamics of sunflower irrigated with saline–sodic water amending by potassium and farm yard manure
Sunflower (Helianthus annuus L.) plants were grown with saline–sodic water (SSW) by treating with potassium (K @ 100 and 200 mg K2O kg−1 soil) and farm yard manure (FYM @ 5 and 10% of soil, w/w). Irrigation with untreated SSW caused soil salinization/sodification, leading to an increase in electrical conductivity (EC) of 165% and sodium adsorption ratio (SAR) 100% with the subsequent increase ...

Farm Dam Liners for Dam Lining Project in Kenya
Farm dam liners have the advantages of small permeability coefficient, large elongation, good environmental protection benefits (compared to concrete and clay materials anti-seepage), lightweight and softness, easy construction, strong regional adaptability, high factory production quality assurance rate, and more convenient operation and maintenance. In the field of anti-seepage, Farm dam liners ...

Regenerative agriculture and climate change
The term “regenerative agriculture” is gaining prominence in climate-related conversations. It dates back to the 1980s when Robert Rodale coined the term, “regenerative organic agriculture” as way to express that organic should be more than simply avoiding chemical inputs. The term has been defined and re-defined by many different authors, sometimes describing very ...

Solvent extraction followed by ultraviolet detection for investigation of tetramethylthiuram disulfide at soil-water interface
Tetramethylthiuram disulfide is a widely used pesticide and a soil treatment agent in the agricultural sector. Consequently, its detection in the environment and investigation of the distribution between the aqueous and soil phases would be of highly importance. In this study, the detection of tetramethylthiuram disulfide in CHCl3 was successfully achieved through absorbance measurements at 280 ...

Soil Water Sensors for Agriculture – Theory and Issues
Soil water sensors have been used for irrigation and water management in agriculture for many years, but with limited success in many cases. Nonetheless, the use of soil water sensors in increasing as water scarcity increases and, conversely, problems associated with over irrigation also increase. Common problems with soil water sensing included sensor failure, problems with wiring, lack of or ...

Nitrapyrin
Nitrapyrin is an organic compound with the formula ClC5H3NCCl3. It is a widely used nitrification inhibitor in agriculture as well as a soil bactericide and has been in use since 1974. Nitrapyrin was put up for review by the EPA and deemed safe for use in 2005. Since nitrapyrin products is an effective nitrification inhibitor to the bacteria nitrosomonas it has been shown to drastically the ...

Aviro D16 Drone: The way to respond to agricultural losses due to pests
Agriculture is the backbone of the critical industry, especially in Southeast Asia regions, and helps sustain food security worldwide. Notably, they produce prominent productions like rice and palm oil. Each region's most scenic coastline is subjected to the country's broadest range of geographical hazards. The sector currently faces some challenges, including a shortage of human ability, ...

Model forecasts long-term impacts of forest land-use decisions
The drive to develop crops for use as biofuel, continues to raise questions about additional uses of forest land. A cutting edge computer model developed at North Carolina State University offers detailed insight to predict the environmental impact – along with understanding forest ecosystem response to global climate change. “We think the model will help policy makers and forest ...

Optimizing Agricultural Water Management through Water Quality Sensors
Water is a precious resource that plays a critical role in agricultural production. As the global population increases, meeting the demand for food and fiber becomes increasingly challenging, particularly in regions facing water scarcity. The utilization of water in agriculture must be efficient, sustainable, and environmentally friendly. This article explores how water quality sensors have ...
