Integrated pest management (IPM) programs have been developed for almost all agricultural and ornamental crop production systems over the past two decades. But only recently have IPM and organic management systems been considered a truly primary approach in professional turfgrass management. The reasons for the dramatic increase in organic approaches are centered on public concern for the envir...

The kinetics of phosphorus (P) desorption in soils is important from plant nutrition and environmental perspectives. An experiment was conducted on the field plots that received 100 t ha of solid dairy manure 1 (DM), sewage sludge (SS), or urban solid waste compost (UC) and one rate of chemical fertilizer (CF) for 1, 3 or 5 consecutive years to investigate the residual and cumulative effects of...

An experiment was conducted as randomized complete block design with three replications and 14 fertilizer treatments in year 2014. The treatments were including the control, application of chemical fertilizers according the soil analysis, application of 15, 30 and 45 tons of municipal  waste compost per ha as simple and with 25, 50 and 75% of chemical fertilizers. The results revealed that the ...

in order to develop the high intensive agriculture, more chemical fertilizers are applied to the soil that resulting in soil degradation and environment deterioration. application of organic manure is an important approach for maintaining and improving the soil fertility and increasing fertilizer use efficiency. therefore, in order to evaluate the effect of organic manures and chemical fertiliz...
