Large amounts of uranium, radium and radium products are redistributed throughout the environment owing to the use of phosphate fertilizers. Potential radiological impacts resulting from direct exposure, inhalation and ingestion of foods grown with fertilizers are discussed. This paper describes a simple method to measure exhalation rate of 222RN from phosphate fertilizers, clay and potatoes in...

Abstract Fertilization in the seedling production phase is essential to form quality seedlings. Thus, aim of this study was evaluate appropriate doses two slow-release fertilizers (SRF1 and SRF2) their nutrient leaching behavior. For this, five different were tested. 0, 2, 4, 6, 8 kg m-³. The height, stem diameter, leaf area, shoot dry mass, root system total Dickson Quality Index measured, for...

The current agricultural system faces several challenges, the most important being ability to feed increasing world population and mitigate climate change. In this context, improvement of fertilizers’ agronomic efficiency while reducing their cost environmental impact is one biggest tasks. Available literature shows that many efforts have been made develop innovative fertilizers defined as ‘sma...
