The idea of eliminating the use of fertilizers which are sometimes environmentally unsafe is slowly becoming a reality because of the emergence of microorganisms that can serve the same purpose or even do better. Depletion of soil nutrients through leaching into the waterways and causing contamination are some of the negative effects of these chemical fertilizers that prompted the need for suit...

the aim of this study was to determine the effects of ensiling and using of fertilizers nitrogen and phosphorus on chemical composition and ruminal dm degradability of safflower plant (carthamustinctorius l.). the safflower plant was cultivated at december 2009, and harvested at june 2010 in flowering stage, chopped to 3-5 cm particles and then ensiled in the laboratory silos for 60 days. the e...

The title of the paper purports to discuss the feasibility of 100% RDF firing for power generation. It is implied that it is possible to fire 100% RDF in a single boiler. However, for the case study cited, the author suggests a much more elaborate system for a 16 MW system. The flow sheet suggests 80% heat input from RDF and 20% from coal. He also suggests that three boilers handle the RDF. Thi...

Present agricultural systems in Myanmar follow the traditional methods which utilize the available natural resources combined with improved cultural practices. Although the use of synthetic chemicals such as fertilizers and pesticides have been well established in Myanmar’s agriculture, the quantity actually used is much lower than the recommended optimum rates. Hence, there is no evidence so f...

The objective of this project is to compare growth and survival rate in Chinese carps reared under traditional culture conditions versus those reared in ponds treated with slurry (anaerobic fermented of cow manure). This experiment was conducted using two treatments one treatment using slurry and the other using cow manure plus chemical fertilizer as the control with three replicates for each....

nowadays, with population growth in urban areas, providing safe water and health is considered basic needs of human, alongside the various pollutants due to urban activities, agriculture and industrial areas on adjacent ranges into urban water resources around the environment is such that study necessary to prevent the pollution of water resources and identification of pollution sources shows. ...

This experiment was conducted in 2012 at the research field of Alborz Research Station, Research Institute of Forests and Rangelands, Karaj, Iran, to study the effect of chemical and biological fertilizers on Sage (Salvia officinalis L.) and replacing biofertilizers instead of high doses of chemical fertilizers. The experiment was conducted in factorial in the form of a randomized complete bloc...

carbonatic origin of most arable land in the country, caused to decrease phosphatic fertilizer use efficiency and because of this phenomenon, farmers annually add a large amount of these chemical compounds to their field to get proper results. international shortage and increasing prices create some problems for importing phosphorus fertilizers to the country. on the other hand using more and m...
