The use of covers may improve establishment seeded turfgrass but their in combination with drip irrigation techniques has not been evaluated. We investigated the effects two cover types and three methods on tall fescue turfgrass. For spring seeding [Schedonorus arundinaceus (Schreb.) Dumort.], turf was successful subsurface (SDI) aboveground (AGD) fine textured soil transition zone. With SDI, A...

Continuous application of P fertilizers under different irrigation patterns can change soil phosphorus (P) chemical behavior and increase soil P levels that are of environmental concern. To assess the effect of long-term different irrigation patterns on soil P fractions and availability, this study examined sequential changes in soil organic P and inorganic P from furrow irrigation (FI), surfac...

Introduction This study aimed to compare the effectiveness of two activated irrigation techniques in removing the smear layer after single-file reciprocating instrumentation in curved canals. Materials and Methods Sixty distobuccal roots of maxillary molars were standardized to create a closed system, and then instrumented using WaveOne Primary (Dentsply Maillefer, Ballaigues, Switzerland) in...

PURPOSE Denitrification is an important biochemical process in global nitrogen cycle, with a potent greenhouse gas product N(2)O. Wastewater irrigation can result in the changes of soil properties and microbial communities of agricultural soils. The purpose of this study was to examine how the soil denitrification genes responded to different irrigation regimes. MATERIALS AND METHODS Soil sam...

in the present experiment, the effects of nitrogen and phosphor fertilizer application in two methods of furrow and trickle irrigation on the yield and quality of sugar beet seed cultivar 7233 were studied. the experiment was conducted as a split factorial in a completely randomized block design with three replications during 2003 and 2004 in hamedan province. main plots were allocated to irrig...
