Two pilot plant products containing 65 and 45% NaP1 zeolite were obtained from two Spanish coal fly ashes (Narcea and Teruel Power Station, respectively). The zeolitic product obtained showed a cation exchange capacity (CEC) of 2.7 and 2.0 mequiv/g, respectively. Decontamination tests of three acid mine waters from southwestern Spain were carried out using the zeolite derived from fly ash and c...

A series of experiments was carried out at Students Farm, Sindh Agriculture University, Tandojam to evaluate the effect of NPK, micronutrients and N-placement on the growth and yield of sunflower during 2005-2006. The sunflower cv. HO-1 was studied under 7 different NPK levels and placement methods (0-0-0 NPK kg ha, 6030-30 NPK kg ha (N as broadcast), 60-30-30 NPK kg ha (N as fertigation), 90-4...

Excess nitrogen (N) caused by straw returning to paddy fields undergoing flooding irrigation deteriorates the water quality. The purpose of this research was use both simulated field and pot experiments explore a new approach using zeolite recycle excess N. results from in stagnant showed N adsorption with different applications (25, 50, 75, 100, 125, 150 g L−1). Pot revealed how reused affecte...

Metam sodium (MS) is often applied to potato fields via sprinkler irrigation systems (water-run, WR) to reduce propagules of soil-borne pathogenic fungi, particularly Verticillium dahliae, to prevent yield loss from potato early dying disease. However, this procedure has not been effective for controlling quality defects in tubers caused by Columbia root-knot nematode (Meloidogyne chitwoodi). I...

Research has documented the effects of tankmixing glyphosate with numerous insecticides on cotton growth and yield; however, no information is available concerning the addition of a residual herbicide such as an aqueous capsule suspension (ACS) formulation of pendimethalin to glyphosate plus an insecticide. Mixtures such as this are important as producers continue to search for costs savings in...

to study the effects of integration of mechanical control with herbicides on yield and yield components of soybean (glycine max) a field experiment was conducted during 2003-2004 at the research farm of agronomy department, agriculture campus of tehran university, karaj. a randomized complete block design (rcbd) of 18 treatments was applied, each treatment being replicated 3 times. treatments i...

magnesium is potentially useful for orthopedic and cardiovascular applications. magnesium and its alloys are light, biodegradable, biocompatible metals that have promising applications as biomaterials. however, the corrosion rate of this metal is so high that its degradation occurs before the end of the healing process. one of the ways to improve the corrosion rate is to compose it with ceramic...

The experiment was conducted at the agriculture field laboratory of Noakhali Science and Technology University during period from October 2021 to January 2022 observe effect various doses cowdung nitrogen on performance mustard. comprised two factors viz: nitrogen. One organic fertilizer like different level cowdung-control 0 t ha-1 (C0), 15 (C1), 30 (C2), 45 (C3) another inorganic - control kg...
