Poorly drained claypan soils can increase the importance of tillage and N management for corn (Zea mays L.) production. Field research in 2008, 2009 and 2010 (high rainfall years) near Novelty, MO (40° 1' N, 92° 11' W) sought to determine the effect of polymer-coated urea (PCU) placement [strip-tillage (ST) deep banded and no-till (NT) broadcast] and application timing (fall, early preplant...

Centella asiatica is an herbal plant with many health benefits due to the content of asiaticoside compounds. Factors affecting are altitude, soil texture, and nutrient status. This research aimed identify effect zeolite, P2O5 fertilizer, media from different altitudes on C. asiatica. The was conducted in a greenhouse August 2017–June 2018. experimental design factorial, completely randomized th...

background: no2 is a poisonous gas that potential to cause major threat to human being health and the environment, as a result, removing this gas from environment seems to be essential. methods: the study aimed to remove this gas from environment using iranian natural zeolite, clinoptilolite. after crushing and preparing two sizes of 1 and 2 mm zeolite they were activated in 380 to 420 ºc for 2...

Calcareous soil suffers from deficiency in available of potassium due to its high contain CaCO3. So, it is important increase the availability potassium. Potassium release rate constant an indicator for ability supply A field experiments sulaimani governorate was conducted evaluate effect amendment with natural zeolite at (0 and 2 t ha-1), three levels Nano fertilizer (0, 5 10 kg conventional K...

A simple and versatile approach has been developed to synthesize different carbon/zeolite T functional membrane materials. The precursors of the membrane are composed of polyimide matrix and dispersed zeolite T particles. Membranes prepared by pyrolysis at 973 K showed excellent gas (H2, CO2, O2, N2, CH4) permeability and selectivity and the gas selectivity (O2/N2, CO2/CH4) of the functional me...

this study was conducted to determine the effect of cliniptilolite natural zeolite on deficit irrigation stress tolerance on maize cultivar ksc704. the experiment was laid out as a factorial design based on randomized complete block with three replications at seed and plant improvement institute, karaj in 2012. four irrigation levels, including irrigation after 70, 95, 120 and 145 mm cumulative...
