Environmental aspects of the application of mineral fertilizers

To increase crop production, it is practically important to study the influence of micro fertilizers in the context of organic fertilizers (compost). The effect of micro fertilizers on the yield, quality, and chemical composition of the fruit of the pepper variety was studied in a compost-based cropping trial. It was found that the combined use of organic and micro fertilizer increased pepper yield by 6.67-19.37%. The sugar content in the optimum varieties increased by 1.07-1.31 times, vitamin C by 1.01-1.14 times, ash by 1.02-1.17 times, and cellulose by 1.06-1.44 times compared to the background. The influence of different concentrations of trace element salts on the chemical composition of pepper fruits was also studied. The concentration and chemical properties of micro fertilizing salt solutions were found to influence both the content and accumulation of TE in pepper fruits. © The Authors, published by EDP Sciences.
