deposition and drift of pydrin in cottonseed oil and water under arid conditions applied with a dual spray system aircraft

a dual spraying system fitted to a cessna ag husky has been used to apply pydrin in cottonseed oil and pydrin in water under arid conditions. a comprehensive sampling array of ground plates, masts and suction air samples was used to determine the deposition and drift of these materials.

nitrogen fertilizer management of cotton grown under drip irrigation in a grumusol

a field experiment was carried out for two years on a grumusol (typic chromoxerert) soil at merhavya, israel, to study the influence of different concentrations of n in soil solution on the growth and yield of drip-irrigated cotton. the soil was analyzed for moisture and no//3-n every two weeks and the concentration of no//3-n in the soil..

electrolyte effects on a nearly second order nematic-isotropic phase transition in a micellar liquid crystal

the phase diagram and results from magnetic susceptibility measurements in the isotropic phase are presented for the lyotropic liquid crystal cesium perfluoro octanoate $plus$ water in the presence of an added salt cscl. based upon the evolution of the cotton-mouton coefficient and in the context of an onsager-type calculation we speculat..

four technological model systems of the sewage-treatment plant of the cotton industry have been dealt with as far as the economic aspect is concerned. flow capacities of the sewage-treatment plant have been analysed. the aim of analysis was to choose a solution which would result in the maximum effects possible at the lowest outlay. (edit..

exploration 3d survey techniques in the gulf

marine 3d seismic survey techniques have in fact separated into two types. the traditional way of conducting marine 3d surveys by traversing a very large number of closely spaced parallel lines is still popular. the newer method on the scene is known as exploration 3d surveying and is basically the same technique but with a much wider lin..

effect of organic acids on aluminum toxicity in subsoils

aluminum has long been recognized as a major limiting factor for root growth in acid subsoils, but little has been done to delineate toxic and nontoxic forms of soil-solution al. in an effort to determine if the presence of organic acids in soil solutions affected al phytotoxicity, short-term, split-root experiments were conducted with co..

canopy temperature response to water stress under partial canopy

unstressed baselines of the crop water stress index for cotton under full ground cover have slopes about twice those under partial canopy cover. these results were consistent between four strains and one commercial variety and were caused by a more aerodynamically rough canopy under partial ground cover. the roughness length and displacem..
