The southeastern United States is characterized as humid subtropical and is subject to extended periods of high ambient temperature and relative humidity. Because the primary nonevaporative means of cooling for the cow (radiation, conduction, convection) become less effective with rising ambient temperature, the cow becomes increasingly reliant upon evaporative cooling in the form of sweating a...

712 Soil physical conditions can aff ect diff usion, environmental fate, and effi cacy of fumigants in soil disinfestation treatments. Water seals (applying water using sprinklers to soil following fumigation) can eff ectively reduce fumigant emissions from sandy loam soils. Soil column studies compared the eff ectiveness of water seals in reducing cis-1,3-dichloropropene (1,3-D) emissions from...

A distinctive feature of the irrigated systems Russian Federation is a large area areas and significant length irrigation canals. With massif on small canals, use electricity to regulate throughput network hydraulic structures economically ineffective. Preference given means automation water supply. Regulation structure based laws fluid flow within it. On canals in Russia, as world practice, wa...

Heat stress (HS) and water (WS) pose severe threats to viticulture, effective management solutions counter their effects on grapevine performance must be examined. In this study, we evaluated the physiological spectral responses of Vitis vinifera L. cv. Sauvignon blanc individual combined (HS + WS) under four different cooling irrigation strategies. The treatments were: standard drip (SI), extr...

To supply water to the fields, an irrigation system is built, which includes a source of supply, intake structure with pumping unit, transport, distribution and working channels or pipes. Closed open networks are built on fields. In closed network, under pressure supplied through pipes hydrants machines installations. The network laid in form temporary pipelines, trays, from by pumps sprinklers...

• Development of experimental datasets for validation spray dispersion simulations. Experimental characterisation butterfly and hollow-cone sprinklers sprays. Sprays measured using single-camera, back-lit, high-speed videography technique. Outdoor experiments involving each sprinkler operating near a 2.4 m cube in wind. Measured wind characteristics deposition on surfaces ground. Processes arou...

Abstract - Green house must be able to control the environment with temperature and humidity parameters that are suitable for plant growth. However, manual watering always done at any time, which is time-consuming farmers. Greenhouses modern technology create automatic controls such as sprinklers. Thus, time spent on plants less than system. In addition, farmers can save water has been wasted a...

Assistance in the application of IoT-based monitoring and watering system technology cultivation family medicinal plants (Toga) for PKK group managing Tosabu garden, Kramas Sub-district, Tembalang District, Semarang, aims to assist park managers, namely Village administrator, caring cultivating various types a mini greenhouse with an area 40 m2. Watering is significant problem during dry season...

use of the double ring infiltrometer to measure soil water infiltration in center pivot irrigation systems is not an accurate approach; because the real conditions of infiltration under center pivot sprinklers is different from what happens in the double ring. in this study, the infiltration parameters were determined under real conditions of a center pivot system. for this purpose, a single ri...
