A strategy for sustainable livestock husbandry wastewater treatment in China
A strategy for sustainable treatment of the livestock husbandry wastewater is proposed, which is to recycle anaerobic treatment effluent as irrigation water. The existing treatment system was modified by deleting the treatment units after the anaerobic digestion. Chinese cabbage and Korean radish were selected as seeding plants in two sets of field irrigation experiments with various portions of ...

Long-term Polyacrylamide formulation effects on soil erosion, water infiltration, and yields of furrow-irrigated crops
Two formulations of water-soluble anionic polyacrylamide (WSPAM) are used in agriculture to reduce erosion and manage infiltration in furrow irrigations, although few if any reports have compared their effectiveness. A control and two WSPAMs, a granular form and the inverse emulsion, or oil-based liquid form, were applied to irrigation water supplied to furrows formed in a silt loam soil with ...

Key Challenges for UK Irrigation in Agriculture
Irrigated agriculture is an integral part of the rural economy, but increasing water use creates several challenges, not least meeting the food demands of a growing population while using as little water as possible to save energy. In this article, we’ll look at the key challenges for UK irrigation in agriculture, to shed light on what the industry must do to preserve itself. ...

Enhancing Agricultural Practices with Ozone for Farm Water Systems
Farmers constantly pursue innovative technologies to improve crop quality and yield in today’s ever-evolving agricultural landscape. Ozone systems have emerged as a game-changing solution in agriculture, offering myriad benefits. The ozone process not only purifies water and improves yield but also prevents mineral deposits from forming in pipes, leaving no chemical residue. This ...

Microbial quality and suitability of roof-harvested rainwater in rural villages for crop irrigation and domestic use
The study aimed at assessing the microbiological quality and suitability of roof-harvested rainwater (RHRW) for crop irrigation and domestic use. In total, 80 rainwater tanks (246 samples) across three rural villages (Ga-Molepane, Jericho and Luthngele) were visited. Culture-based techniques were used to isolate bacterial microbes and identities were confirmed using matrix-assisted laser ...

Magnetic particle treatment for irrigation water greener, better, cheaper, faster
The wells of central California are the main water source to sustain agriculture in the region, but the brackish water contains high concentrations of total dissolved solids (TDS) in general, and geologically occurring recalcitrant elements - like boron - in particular. Boron is hard to remove using membrane technology such as Reverse Osmosis, and Ion Exchange is quite burdensome in cost, ...

The effect of winter flood irrigation with saline water on groundwater in a typical irrigation area
Flood irrigation in the winter has been widely applied in northwest China for several years, but little attention has been paid to the flood irrigation program to date. In order to seek a reasonable irrigation quota, a flood irrigation experiment using two common quotas (1,800 and 1,200 m3 ha−1) was conducted in an area irrigated by saline water in the Nanjiang basin with shallow ...

Irrigation and Nitrogen Best Management Practices Under Drip Irrigated Vegetable Production
Abstract Plastic mulch and drip irrigation are commonly used in high intensity vegetable production regions such as Florida. Drip irrigation can be much more efficient than sprinkler irrigation since only the root zone of the cropped area is irrigated. However, improper irrigation management can lead to wasted water and leaching of soluble chemicals such as nitrate. In this project, several ...

Canopy gas exchange measurements of cotton in an open system
A portable, open transparent chamber system for measuring canopy gas exchanges was developed and tested. Differentials between incoming and outgoing atmospheric H2O and CO2 concentrations were used to calculate canopy transpiration (E) and net assimilation (A) at 10-s intervals using solenoid valve actuated sample lines connected to an infrared gas analyzer. A programmable data logger controlled ...
