The use of fast growing trees could be an alternative in trace element contaminated soils to stabilize these elements and improve soil quality. In this study we investigate the effect of Paulownia fortunei growth on trace element contaminated soils amended with two organic composts under semi-field conditions for a period of 18 months. The experiment was carried out in containers filled with tr...

On the examination of soil around the roots of Mustard in Kashmir Valley, two species of Nematodes were met, namely Aphelenchus radicicolus Steiner,1931 and Psilenchus haki Handoo, 1977. The species were identified under Stereoscopic microscope with the little intraspecific variations from the original in terms of the dimensions. The effect of organic amendments including poultry manure, pigeon...

The application of organic amendments can be an appropriate solution to reclaim and improve physical propertiesof saline-sodic soils. In this research, an experiment was performed under greenhouse conditions to study the effect ofamendments to the physical properties of loamy saline-sodic soil. The five treatments were control (withoutamendment), municipal solid waste compost (MC), vermicompost...

abstract soil salinity in huge parts of the world, especially in arid and semi-arid regions, is a factor limiting growth of plant and other organisms. earthworm can be considered as an indicator of soil quality in agroecosystems, because of a positive correlation between earthworm abundance and the productivity of cropped plants. the main objective of this study was to realize the interaction b...

Poultry litter is a valuable nutrient source for crop production. Successful management to reduce ammonia and its harmful side-effects on poultry and the environment can be aided by the use of litter amendments. In this study, three acidifiers, two biological treatments, one chemical urease inhibitor and two adsorber amendments were added to poultry litter. Chemical, physical and microbiologica...

Recent adoption of national rules for organic crop production have stimulated greater interest in meeting crop N needs using manures, composts, and other organic materials. This study was designed to provide data to support Extension recommendations for organic amendments. Specifically, our objectives were to (i) measure decomposition and N released from fresh and composted amendments and (ii) ...

Two independent trials were established during the years of 2009 and 2010 with M.26 apple rootstocks and Prunus mahaleb L. seedlings in three different locations to evaluate the effect of seven organic fertilizers and amendments on the growth of rootstocks in an organic nursery in the first year of an operation. The products tested were a microbial consortium, two kinds of vermicomposts extract...

Field experiments were conducted to determine the effects of organic andinorganic amendments on weed suppression in sweet maize cultivation (Zea maysL.). A randomized complete block design was employed with four replicates pertreatment with each organic amendment used at half (x/2), single (x=10 t ha-1) anddouble (2x) rates (organic fertilization: cow manure, poultry manure and barleymulch; syn...

Large fraction of mineral nutrients in natural soil environments is recycled from complex and heterogeneously distributed organic sources. These sources are explored by both roots and associated mycorrhizal fungi. However, the mechanisms behind the responses of arbuscular mycorrhizal (AM) hyphal networks to soil organic patches of different qualities remain little understood. Therefore, we cond...
