this paper deals with the suitability of agricultural and municipal organic wastes as growing media components for ornamental plants. nine growing media prepared by mixing the main components of peat (p), hazelnut husk (h) and maize straw (m) with the fertilizer sources of municipal solid waste compost (c), bio-solid (b) and poultry manure (pm) were compared against soil-based (c1) and peat-bas...

Our previous work demonstrated that application of a bio-organic fertilizer (BIO) to a banana mono-culture orchard with serious Fusarium wilt disease effectively decreased the number of soil Fusarium sp. and controlled the soil-borne disease. Because bacteria are an abundant and diverse group of soil organisms that responds to soil health, deep 16 S rRNA pyrosequencing was employed to character...

recently, biological fertilizers extensively recommended because of over application of chemical fertilizer and their effects on environment and production resources. in order to study the effect of inoculate phosphate solubilization microorganisms (psm) and plant growth promoting rhizobacteria (pgpr) on nutrient use efficiency in corn [zea mays (l.) cv. sc 604] an experiment was conducted in 2...

Biogas and bio-methane that are based on energy crops are renewable energy carriers and therefore potentially contribute to climate protection. However, significant greenhouse gas emissions resulting from agricultural production processes must be considered. Among those, the production and use of fertilizer, and the resulting leaching of nitrous oxide (N2O) are crucial factors. This paper provi...

To ensure long-term food production in a changing world, it is critical to identify field management practices that increase crop yields and maintain soil health. Additionally, sustainable agriculture needs provide experimental evidence support the use of traditional agricultural practices. In this study, 20-year investigation effects different combinations fertilizer types (control, chemical f...

The effect of seed inoculation by phosphate solubilizing microorganisms and different levels of phosphorus chemical fertilizer on yield and yield components of barley (Karoon x Kavir cultivar) was studied in Experimental Farm of College of Agronomy and Animal Sciences, University of Tehran during 2006-2007 growing seasons. The experimental treatments were arranged in split plot factorial based ...

A new manure treatment technology developed as an alternative to anaerobic lagoons on swine (Sus scrofa domesticus) farms includes solid-liquid separation and subsequent recovery of soluble P as calcium phosphate from the wastewater. The objective was to determine the agronomic effectiveness of this calcium phosphate material. A greenhouse study was conducted with annual ryegrass (Lolium multif...
