Livestock farming produces high volumes of animal slurry that can be sanitized using low-cost treatments by pH adjustment, reducing pathogen contamination, and promoting valorization as a safe fertilizer. This work aims to evaluate the impact sandy soil amendment with dairy treated adjustment on potential release nutrients coliforms into groundwater. A laboratory column leaching experiment was ...

Currently the world is moving towards organic production of crops for the discovered and envisaged advantages. Despite this, farmers are faced with the challenges of the bulkiness of organic fertilizer to be used and further gains that could be accrued from it even if sacrifice of using it is made. To be quite sure of the appropriate fertilizer type to be used in improving quality as well as th...

Fertilizer application is a common anthropogenic alteration to terrestrial systems. Increased nutrient input can impact soil microbial diversity or function directly through altered soil environments, or indirectly through plant-microbe feedbacks, with potentially important effects on ecologically-important plant-associated mutualists. We investigated the impacts of plant fertilizer, containing...

1 Why don’t farmers use fertilizers: 2 Evidence from Field Experiments in Western Kenya 3 (PRELIMINARY AND INCOMPLETE) 4 April 29, 2006 5 6 Esther Duflo, Michael Kremer and Jonathan Robinson 7 8 9 Abstract 10 11 This paper reports on randomized field experiments set up to investigate 12 various reasons for the low usage of fertilizer in Western Kenya. 13 Demonstration plots set up on farmer’s f...

Vegetable organic waste can cause an unpleasant odour and pollute the environment without proper management. One alternative to handling this is process it into liquid fertilizer. Liquid fertilizer (POC) a solution resulting from decomposition of plant residues animal manure that contains more than one nutrient needed by plants. The purpose holding counselling provide knowledge homemakers in RT...

A field-scale plot study was conducted at Virginia Tech’s Prices Fork Research Farm, to evaluate the transport of nutrients in runoff from manure and fertilizer applied at P-based agronomic rates to cropland planted to corn. Simulated rainfall events representing 2to 10-year storms in southwest Virginia, occurring 1 and 2 days following manure and fertilizer application were used to generate ru...

Both organic and conventional farming processes require energy input in the form of diesel fuel for farming equipment, animal feed, and fertilizer compounds. The most significant difference between the two methods is the use in conventional farming of mineral fertilizers and pesticides that are minimally employed in organic management. It is argued that organic farming is more environmentally f...

A Bulgarian project at Maritsa East power station demonstrated the proper transformation of air pollutants (SOx and NOx) into nitrogen fertilizer. Although this technology has not been put into practice in Bulgaria, it seems feasible on an industrial scale and so it may help to ease Portugal’s reliance on imports of nitrogen fertilizer and thereby contain the outfl ow of Portuguese funds. The d...

Increased fertilizer input in agricultural systems during the last few decades has resulted in large yield increases, but also in environmental problems. We used data from published papers and a soil testing and fertilization project in Shaanxi province during the years 2005 to 2009 to analyze chemical fertilizer inputs and yields of wheat (Triticum aestivum L.) and maize (Zea mays L.) on the f...
