Abstract— Drug delivery systems are developed to provide a necessary concentration and prolonged effect of the active substance in organism. Orally administered protein preparations require protection from proteolysis gastrointestinal tract. Biocompatible hydrophilic polysaccharides composition matrix especially promising, since they do not irritate intestine gradually cleaved by specific glyco...

ABSTRACT No-till planting and the use of organomineral fertilizers are crop management practices that increase soil organic matter, thereby mitigating leaching cycling a considerable amount nutrients, with potential to improve yield. This study aimed assess agronomic performance cabbage grown under no-till system, using different cover crops phosphorus sources. A randomized block design was use...

Microbial biomass nitrogen and carbon were studied in long-term field experiments with continuous cultivation of silage maize and with crop rotation. a positive effect of organic fertilizers on the microbial biomass nitrogen and the carbon content in soil was observed. Statistically significant effect of organic fertilizers on the higher content of microbial biomass C and n was established in t...

There seems to be conflicting information about foliar fertilizers and their timing of application to cotton. Much of the confusion lies in the variety of fertilizer products available. A cotton fanner now has a choice of applying foliar fertilizers (according to fertilizer labels) beginning at the first true leaf stage and continuing until defoliation. This newsletter will focus on available i...

Nitrogen is the most important essential nutrient that plays a major role in achieving maximum crop yield in agriculture. Therefore, nitrogen fertilizers such as ammonium sulfate and urea have been extensively used in modern agriculture. These fertilizers are generally oxidized to nitrate via nitrite by nitrifying microorganisms in the agricultural field (4, 10, 11). The serious environmental p...

Bu çalışmanın amacı, uygun koşullar altında katı organomineral gübre ile gübrelemenin toprağın azot prosesleri üzerindeki etkilerini belirlemektir. Organomineral dozlarının süreçlerine etkisini değerlendirmek için, 100 g toprak örneği farklı miktarlarda (20 ve 40 kg–1) muamele edilmiştir. Örnekler daha sonra 15 30 gün süreyle kontrollü karanlıkta 28° C'de inkübe Alınan örneklerde NH4-N, NO3-N, ...

Urban agriculture has been recently highlighted with the increased importance for recreation in modern society; however, soil quality and public health may not be guaranteed because of continuous exposure to various pollutants. The objective of this study was to evaluate the soil quality of urban agriculture by soil microbial assessments. Two independent variables, organic and inorganic fertili...

The absorption spectra of dye-doped polymer thin films made from a variety of five dyes and six matrices, either organic or organomineral, are analyzed to evaluate the residual absorption in the red wavelength tail and in particular at amplified spontaneous emission (ASE) wavelengths. An absorption cutoff wavelength is defined as the extrapolated wavelength at which the absorption losses are ex...
