Synthetic (e.g. urea) and organic fertilizers (e.g. compost) differed markedly in N isotope composition and the greater the difference between organic and synthetic fertilizer the more robust will be the differentiation of crops and vegetable grown under different farming systems. The objective of this study was to compare nitrogen and carbon isotope composition of organic fertilizers and manur...

Yeasts can be enriched with microelements, including iron; however, special physicochemical conditions are required to formulate a culture media that promotes both yeast growth and iron uptake. Different iron sources do not affect biomass formation; however, considering efficacy, cost, stability, and compatibility with Saccharomyces cerevisiae metabolism, ferrous sulphate is recommended.

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...

Controlledrelease fertilizers (CRFs) offer an excellent option to improve nutrients uptake by plants and reduce the environmental hazards due to excess release of chemicals. Polymer-coated fertilizers, compared to the other types of CRF, are by far the most intensively researched topic because of their great characteristics. Polymercoated fertilizers, which are less sensitive to the soil and en...

Organic fertilizer is a source of necessary for agricultural plants macro-, microelements and carbon dioxide. Due to their gradual mineralization nutrients enter the during whole period vegetation. In production, in particular organic fertilizers, main factor determining profitability effective use energy. The aim work was carry out analysis energy efficiency production compost vermicompost fro...

Biomass is one of the most important sources renewable energy in industry. It assumed that by 2050 global deposit could be covered 33–50% biomass combustion. As with conventional fuels, combustion produces by-products, such as fly ash. Therefore, along growing interest use a source energy, production ash by-product increases every year. estimated approximately 476 million tons ashes per year ca...

The article discusses ways to convert unsuitable saline lands into suitable ones using the “Carbon Dioxide Forming Utility Model” and integrated use of desalinating biocomposites. A three-year study proved that among 10 options studied, best restoring soil fertility turned out be 10-9-8 7 options. In these options, savings in wash water, respectively, were according option: 1.46 times; amount c...

In intensive fruit production, in order to obtain high yields, it is necessary to use high fertilization rates as well as plant protection products. An alternative to that kind of production is presented by natural stimulators of plant growth and development called biofertilizers, biopreparations, biostimulators or phytostimulators. They are preparations of natural (plant or animal) origin, har...

Accumulating evidence suggests that hyperphenylalaninemia in phenylketonuria (PKU) can cause neuropsychological and psychosocial problems in diet-off adult patients, and that such symptoms improve after resumption of phenylalanine-restricted diet, indicating the need for lifetime low-phenylalanine diet. While limiting protein intake, dietary therapy should provide adequate daily intake of energ...
