The transport of three emerging pollutants through an agricultural soil irrigated with untreated wastewater
The aim of this work was to determine the mobility of naproxen, carbamazepine, and triclosan through a wastewater-irrigated agricultural soil. Transport experiments were carried out using undisturbed soil columns taken at 10 and 40 cm depths. The mobilization of the pollutants was evaluated using two hydrological regimes transient flow for superficial columns and steady-state conditions for the ...

A simple approach to assess N load capacity of rice paddy fields in the southern Taihu Lake watershed
High nitrogen (N) leaching from irrigated agricultural soils is the result of N input exceeding soil N load capacity (NLC). A simple approach was developed in this research to assess the NLC of paddy soils in the southern Taihu Lake watershed. Paddy soils were classified into four types (Submergenic, Illuvium, Gleyed, and Percogenic) and 28 soil samples representing all four types were ...

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 ...

Is colloid-facilitated Phosphorus leaching triggered by Phosphorus accumulation in sandy soils?
The leaching of colloidal phosphorus (Pcoll) contributes to P losses from agricultural soils. In an irrigation experiment with undisturbed soil columns, we investigated whether the accumulation of P in soils due to excess P additions enhances the leaching of colloids and Pcoll from sandy soils. Furthermore, we hypothesized that large concentrations of Pcoll occur at the onset of leaching events ...

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 ...

Irrigation Systems 101: What you need to know
In the perfect scenario everyone could rely on rainwater for their farming practices, but this is not always the case. This is why employing the right choice from the different irrigation systems available is crucial for agricultural success. Irrigation systems are basically an artificial way to provide water to fertile soil for agricultural purposes. Crop irrigation is necessary to overcome ...

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 ...

Perceptions and practices of farmers towards the salinity problem: the case of Harran Plain, Turkey
The Harran region, located in the South-eastern part of Turkey, is facing an increasing salinity problem due to excessive and inefficient irrigation practices. In this paper, we survey 619 cotton producers in the region and analyse their perceptions and practices towards soil salinity. The survey results indicate that formal education and training are the central factors that determine the ...

Results from the ground up
Maintaining soil health and increasing bushels Soil health is the most important aspect of your farm fields. Without healthy soil, you face a tough challenge each year. When your soil profile is strong and not deficient in any nutrients or minerals, you increase your chance of a successful growing season. More than anything, healthy soil gives you the chance to increase your bushels. If your soil ...

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 ...

Integrating Soil Sensors for Enhanced Productivity
Modern agriculture heavily relies on technology to increase productivity and ensure sustainability. One of the most promising technological advancements in recent years is the integration of soil sensors in farming practices. Soil sensors are devices that measure various soil properties such as moisture, nutrients, temperature, and pH levels. By providing real-time data, soil sensors can help ...

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 ...

Performance of solid-state sensors for continuous, real-time measurement of soil CO2 concentrations
Recent advances in sensor technology provide a robust capability for continuous measurement of soil gases. The performance of solid-state CO2 sensors (Model GMM220 series, Vaisala, Inc., Helsinki, Finland) was evaluated in laboratory, greenhouse, and irrigated winter wheat (Triticum aestivum L.). In ambient CO2 concentration, the GMM222 sensor averaged 427 ± 8.3 µL L–1. Under variable CO2 ...

Improved Agricultural Irrigation Scheduling Using a Soil Water Content Sensor - Case Study
Abstract The key to scheduling irrigation timing and amounts is determining moisture depletion in the soil. Two common methods include tracking crop evapotranspiration (ETc) and tracking the water content with a sensor buried in the soil. In Colorado, a popular online tool that estimates the ETc for a variety of well-irrigated crops is the Colorado Agricultural Meteorological Network (CoAgMet). ...
