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 ...
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...
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...

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...
the effect of different fertilizing systems and drought stress during grain development on grain minerals of barley (hordeum vulgare l.) was studied in field experiments on a clay-loamy soil during 2007 and 2008 growing seasons. the treatments consisted of three irrigation regimes (main plots) of: non-stressed (ns, normal irrigation continued until the end of plant physiological maturity), ...
Soil biochemical properties and microbial communities are usually considered as important indicators of soil health because of their association with plant nutrition. In this study, we investigated the impact of long-term application of bioorganic fertilizer (BOF) on soil biochemical properties and microbial communities in the apple orchard soil of the Loess Plateau. The experiment included thr...
A study using 51 wheat, 56 barley and 34 oat grain samples was conducted to investigate the feasibility of predicting the apparent metabolizable energy (AME) value of these cereals for poultry. Stepwise regression analyses were performed to evaluate the relationship of AME with starch, ether extract (EE), crude fiber (CF), soluble sugar (SS), ash and crude protein (CP) (for wheat and barley gra...
