a greenhouse experiment was conducted during the growing seasons (2008/2009 and 2009/2010) to investigate the effects of water quality and soil amendments, irrigation methods and rates on tomato (solanum lycopersicon l. cv. red gold) yield and water use efficiency (wue). irrigation management treatments were fresh (0.86 ds m-1) and saline waters (3.6 ds m-1), surface and subsurface irrigation m...

redbud (cercis griffithii) is an iranian native species that plays a crucial role in protecting soil and water in zagros forestsareas. although many reforestation projects of this species in this area were unsuccessful, the restoration of redbud must continue using new applied studies to help conserve this precious resource. this can be achieved through increasing the quality and quantity of se...

We analyzed during two garlic crop cycles, the effects of chicken manure and vermicompost on soil chemical and biological properties in an agricultural farm irrigated with municipal wastewater of central-western Argentina. Also we evaluate garlic yield and possible health risks as resulting from the organic amendments and the wastewater use. We found that: a) different doses and types of amendm...

Population densities of nematodes in field soil without plants were monitored for 10 months following application of organic amendments to pots in a greenhouse. The four treatments consisted of three different kinds of organic amendments: homogeneous crop residues of maize (Zea mays, C:N = 48.0:1), Texas panicum (Panicum texanum, C:N = 32.9:1), or velvetbean (Mucuna pruriens, C:N = 18.6:1), plu...

Leaching of inorganic arsenic (As) from chromated copper arsenate (CCA)-treated wood may elevate soil As levels. Thus, an environmental concern arises regarding As accumulation in vegetables grown in these soils. In this study, a greenhouse experiment was conducted to investigate the ability of As-hyperaccumulator P. vittata and organic amendments in reducing As uptake by lettuce (Lactuca sativ...

Mycorrhizal fungi have substantial potential to influence plant distribution, especially in specialized orchids and mycoheterotrophic plants. However, little is known about environmental factors that influence the distribution of mycorrhizal fungi. Previous studies using seed packets have been unable to distinguish whether germination patterns resulted from the distribution of appropriate edaph...

The use of organic matter such as animal manures, human waste, food wastes, yard wastes, sewage sludges and composts has long been recognized in agriculture as beneficial for plant growth and yield and the maintenance of soil fertility. The new approaches to the use of organic amendments in farming have proven to be effective means of improving soil structure, enhancing soil fertility and incre...

Abstract Soil amended with rice straw compost significantly reduced sheath blight severity. The disease caused by the fungus Rhizoctonia solani Kühn is a severe disturbance to cultivation in Indonesia. R. soil borne fungi and highly competitive as saprophyte. In mature compost, propagules form of sclerotia germination were suppressed hyperparasites other biological control agents. Compost matur...

Pot and field experiments were conducted to evaluate bioavailability of Cu in contaminated paddy soil (PS) and phytoremediation potential by Elsholtzia splendens as affected by soil amendments. The results from pot experiment showed that organic manure (M) applied to the PS not only remarkably raised the H2O exchangeable Cu, which were mainly due to the increased exchangeable and organic fracti...
