to compare potential of two organic materials including sewage sludge (ss) and municipal solid wastecompost (msw) on micronutrients entry to soil, a research was conducted as split-plot arrangement basedon randomized complete block design with three replications in research field of sari agriculturaluniversity. main-plot (fertilizer treatments) included 20 and 40 ton/ha ss, 20 and 40 ton/ha ss ...
in order to investigate distribution status of heavy metals in cropping systems of water logging and dry farming, an experiment was conducted as split-plot arrangement based on randomized complete block design with three replications in research field of sari agricultural science and natural resources university. a paddy-soil considered for water logging system and the planted field with vegeta...
Sewage sludge (SS) as a source of macro- and micro nutrients has been utilized in many countries for crop and vegetable production. To compare the influence of SS with chemical fertilizer on macro- and micro nutrients bioavailability in three textural classes of a calcareous soil after harvesting spinach (Spinacia oleracea L.), a factorial experiment was carried out in a completely randomize...
Abstract Addition of sewage sludge (SS) in soil causes increasing soil organic matter, which in turn improves soil physical properties, and could supply part of the nutrients required by plants. For comparison of SS application and chemical fertilizer treatment (CFT) on yield and concentration of some macro and micro nutrients in spinach, a greenhouse factorial experiment, arranged in a comple...
sewage sludge with having the organic matter is considered as a source of micro and macro elements. in order to investigate the effect of different levels and period of application of sewage sludge (ss) on organic matter, respiration, and acid and alkaline phosphatase activity, factorial design were studied, in 3 replications. sewage sludge at five levels, (20 and 40 tons of sewage sludge, 20 a...
in order to study the effect of vermicompost individually and enriched with chemical fertilizer on soil micronutrient content and micronutrient concentration of lettuce (lactuca sativa l.), athree year experiment was conducted with randomized complete block design in two factors and three replications at the experimental farm of sari agricultural sciences and natural resources university in 200...
background & aim: thymus daenensis is recognized as aromatic herbs, which used in food, flavoring, pharmaceutical, and perfumery industries. this study was conducted to investigate the response of t.daenensis to different fertilizers (chemical and organic) along with chitosan. experimental: treatments consisted of different fertilizers including: f1 =c (control without manure and fertil...
Biological indicators are considered soil quality elements, due to their dependence on soil organisms. In order to investigate The effect of compost and vermicompost enriched by chemical fertilizers and manure on soil organic carbon, microbial respiration, and enzymes activity in basil plant's rhizosphere, a field experiment was conducted as a split-plot design with randomized complete blocks a...
in order to study the influence of municipal waste compost and chemical fertilizer on yield and yield components in maize (zea mays l.) an experiment was conducted at research farm of sari agricultural sciences and natural resources university during 2007. the experiment was arranged in split plots based on complete randomized block design with two factors and three replications. main plot incl...
In order to investigate the effect of vermicompost on physical and chemical properties of soil, an experiment was carried out in split plot based on complete randomized block design in three replications in Sari Agricultural Sciences and Natural Resources University. The physical and chemical properties of soil included bulk density, particle density, total porosity, water holding capacity, fie...
