With Increasing Energy Demand in the World and to keep Environment Friendly, biogas technology has attained a notable position for the future scope. This paper tells about a comprehension review on anaerobic digestion of cow dung and food waste with Water hyacinths to enhance biogas productions. Water hyacinths are treated as waste in rivers, ponds, but they have high potential in biogas produc...

A prerequisite to use organic fertilizers in a sustainable way is to quantify the amount of phosphorus and potassium available for plants that could be taken up by a crop. The objective of this study was to evaluate direct and subsequent influence of organic fertilizers addition (poultry manure and two types of composts) on the changes of bioavailability of phosphorus and potassium in soil and ...

The objective of this study was to evaluate the influence of organic (cattle manure) and inorganic fertilizers [composite NPK (15:15:15)] and natural zeolites on soil properties, vegetative growth and yield of apple plants grown on vertisol under Cacak conditions (Western Serbia). The results showed that the combined fertilization induced a decrease in acidity, an increase in humus content, a p...

Nitrogen (N) is a macronutrient which required for growth of plants. The most common way providing nitrogen to the plants through urea fertilizers. With increasing demand crops, usage and as fertilizer has also been increasing. A lot that supplied in form fertilizers actually gets wasted. Almost 40–70 % not utilized by plants, generating environmental problems like eutrophication, therefore the...

agricultural activities have always been partly responsible for the emission of greenhouse gases and other environmental contaminants in the atmosphere. thus, studying on the environmental effects of agricultural activities and proposing appropriate strategies to mitigate these adverse effects can be paramount importance. in this study, in order to determine the environmental impacts of peanut ...

This research was conducted to evaluate effect of potassium and iron fertilizers on agro-physiological traits affected different irrigation regime of corn in Shahryar (Tehran province, central of Iran) via a split-split plots arrangement based on randomized complete blocks design with three replications during 2015. The main plot included different irrigation regime (Normal irrigation and stop ...

The purpose of the research is to obtain micronutrient fertilizers by applying salts and their complex forms phosphorus obtained in incomplete standards nitric acid or salt mixtures. Central Kyzylkum phosphorites (low-grade P 2 O 5 -12.38%, CaO-43.68%, CO -13.48%, non-enriched -16.38%, CaO-45.93%, -18, 15%, SO 3 -1.86%, thermoconcentrate -27.40%; CaO-54.68%; - 4.52%) were decomposed with at dif...
