Optimal conditions were found for the reactions of aniline and its hydroxy-, carboxy-, methyl-, and nitro-substituted derivatives with p-dimethylaminocinnamaldehyde in the presence of sodium dodecyl sulfate micelles in the pH range 136. A correlation was revealed between the optimal pH value pK a of aromatic amines. The reaction in the model system aniline3p-dimethylaminocinnamaldehyde3sodium dodecyl sulfate in micelles formed by anionic surfactants is accelerated more than 1000-fold due to increased concentration of the reactive species in sodium dodecyl sulfate micelles.
The effectiveness of sapropel as an organic fertilizer is revealed. It was compared with the traditional organic and mineral fertilizers. So, the most noticeable softening of the soil compared to the control variant was after application of sapropel. During the study, application of sapropel maximally increased the content of nitrate nitrogen in the soil from 2.8 to 4.1 mg/kg, exceeding the indicator of ammonium nitrate by 48.8% and manure by 36.6%. Sapropel increases the content of mobile forms of potassium in the soil over an average of 2 years from 306 to 316 mg/kg, while the content of mobile phosphorus is minimal - 20.3 mg/kg. The highest yield of spring wheat was in the variant the variant after application of ammonium nitrate in a dose of N60 (1.64 t/ha) and sapropel in a dose of 6 t ha (1.57 t/ha).
At present, work is underway in Russia to expand the species diversity of plants, to provide processing enterprises of the light and food industries with domestic raw materials. The purpose of the research is to study the effect of complex mineral fertilizers containing trace elements on the yield of guar grain. The studies were carried out in the soil and climatic conditions of the Lower Don on ordinary chernozem. On average for 3 years the highest yield of 156.0 g / m2 was obtained when applied fractionally, in three terms (in the phases: steming, budding, fruit formation) of complex fertilizer Ecogrinvit legumes in an amount of 6 l / ha (2 l / ha for one feeding) with a consumption rate working solution of 200 l / ha (for one treatment). The effect of fertilizers was 183.6%. Trace elements copper, boron and molybdenum contained in the studied complex fertilizers and applied fractionally to vegetating guar plants act not only as nutrients and as elements protecting plants from pathogens.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
