Human urine was used as a fertilizer in cabbage cultivation and compared with industrial fertilizer and nonfertilizer treatments. Urine achieved equal fertilizer value to industrial fertilizer when both were used at a dose of 180 kg N/ha. Growth, biomass, and levels of chloride were slightly higher in urine-fertilized cabbage than with industrial-fertilized cabbage but clearly differed from non...

There have been several recent developments in slow-release fertilizers. These materials supply nutrients continuously over an extended period in contrast to water soluble fertilizers which are immediately available after incorporation in moist soil. Slow-release fertilizers are not subject to rapid leaching loss and do not easily burn plants from over-application. The major need for slow relea...

ABSTRACT Kale is a vegetable that has high nutrition content, and balanced fertilization essential to ensure yield quality of agricultural products. Curly kale, less known than regular leaf new possibility for consumption. However, little about the influence type on nutritional characteristics. This study aims evaluate using organic fertilizers productivity, microbiological, physico-chemical ch...

We studied the effects of applying different composts (urban organic waste, green waste, manure and sewage sludge), mineral fertilizer and compost plus mineral fertilizer on chemical, biological and soil microbiological parameters over a 12-year period. The organic C and total N levels in soils were increased by all compost and compost + N treatments. Microbial biomass C was significantly (P £ ...

due to uncontrolled dump of dried municipal sludge and its use by farmers as soil conditioner and/or fertilizer, an extensive research was conducted in order to determine the microbiological characteristics of municipal sludges produced at three major cities, namely, qateef, dammam and khobar in the eastern province of saudi arabia. sludge samples were collected, from sand drying beds, twice a ...

Diverse land use activities can elevate risk of microbiological contamination entering stream headwaters. Spatially distributed water quality monitoring carried out across a 17 km(2) agricultural catchment aimed to characterize microbiological contamination reaching surface water and investigate whether winter agricultural land use restrictions proved effective in addressing water quality degra...

Slow-release fertilizers are gaining acceptance to increase fertilizer use efficiency and reduce environmental impact. The release of nitrogen from methylene urea, a common slow release N fertilizer, is controlled by microbial decomposition. An enzyme hydrolyzing slowrelease nitrogen fertilizer, methylene urea, was purified from Rhizobium radiobacter (Agrobacterium tumefaciens) to homogeneity u...

in order to investigate the microbiological safety of sanitary tissues made of recycled scrap papers in iran, random samples were taken for one year with the cooperation of the iranian standard and industrial research institute (karaj unit), of 44 types of sanitary tissues, two samples of each type including tissues, toilet papers and dippers as well as a control sample and their probable conta...

background and objectives: the microbiological monitoring of the water used for haemodialysis is important especially for legionella and non-fermentative bacteria since patients with end stage renal disease (esrd) are suffering from deteriorated function of immune system. materials and methods: a total 50 water and dialysate samples were weekly collected over a period of 10 weeks from 5 sites. ...
