abstract efficient use and management of organic matter are important aspects of sustainable agricultural. organic matter is relatively low in majority of soils in iran, and continuous use of n fertilizer would create environmental hazards. therefore, the combined use of n fertilizer and organic wastes is an effective strategy. the purpose of this study was investigating of residual effects of ...

This work presents the dynamics of E. fetida (Sav.) earthworm populations during vermicomposting of duckweed (Lemna minor L.) biomass in small containers, and provides properties of the vermicomposts produced. An experiment was conducted under laboratory conditions (in darkness, at an average temperature 25±5oC, with substrate moisture 70-75%). Test pots (3 replications for each duckweed treatm...

this study aimed to investigate the effects of tow nanoparticles (nps) on the absorption,accumulation, reproduction of the eisenia fetida. a 4×2×2 factorial experiment in a randomized completeblock design with three replications was conducted. the factors included in the experiment are the content ofnps at four levels (0, 0.4, 0.8, and 1.2gr/kg weight of substrate), the type of nps at two level...

Manure from swine treated with antimicrobials as feed additives is a major source for the expansion of the antibiotic resistance gene (ARG) reservoir in the environment. Vermicomposting via housefly larvae (Musca domestica) can be efficiently used to treat manure and regenerate biofertilizer, but few studies have investigated its effect on ARG attenuation. Here, we tracked the abundances of 9 A...

Hemp, Cannabis sativa is certainly a mul­tifunctional as well niche crop, due to great po­ten­tial for innovative use of its different products. Aspects hemp mineral nutrition are very important in the cultivation these plants, particular make cul­ti­vation environmentally friendly by replacing synthetic fertilizers with organic ones. Among fertilizers, vermicompost has gained attention within ...

The mung bean (Vigna radiata L.) is a member of the Fabaceae family. It major grain legume widely farmed in tropical and subtropical regions worldwide. Mung versatile crop that responds well to fertilizers low nitrogen requirements due its leguminous nature. present experiment evaluated effects different types organic manure on growth, yield, physicochemical properties identify best integrated ...

Aims: The combination of various sources organic manures along with liquid is important to maintain nutrient availability crop and sustain higher level soil fertility. aim meet the demand parching sorghum as per requirement at different stages through solid which can give greater productivity crops.
 Study Design: experiment was laid in Randomized Complete Block Design 9 treatments replica...

An on-farm study of 54 representative Wisconsin dairy farms was conducted to evaluate the influence of biophysical and socioeconomic factors on overall feed, fertilizer, and manure nutrient use. This report validates 1) how well data on cow diets, feed analyses, and milk production reflected established feed-milk-manure relationships; and 2) how well farmer-recorded data on manure land applicat...

Alternaria solani Sor. is one of destructive pathogens in solanaceous plants including tomato. Bacteria and yeast isolated from water extract organic matters are potential as biological control agents plant pathogenic fungi. Mechanisms antagonism bacteria can be through antibiosis. This study was conducted to examine the abilities culture filtrate volatile compounds produced by antagonistic com...
