Sustainable management practices are crucial for the longevity of a monoculture vineyard, especially in the context of a changing climate. Therefore, soil management practices in a vineyard (T: tillage, T+FYM: tillage + farmyard manure, G: grass strips, G+NPK1: grass strips + rational rates of NPK, and G+NPK2: grass strips + higher rates of NPK) were tested in a temperate climate of Slovakia (Central Europe) under specific soil conditions (Rendzic Leptosol). We investigated the influence of continuous cropping on soil chemical properties and microbial communities during the dry and warm year of 2022. The results showed that the soil pH was higher by 19%, 21%, 24% and 13% in T, T+FYM, G and G+NPK1, respectively, compared to G+NPK2. The lowest soil organic matter (SOM) content was found in T, and it increased in the following order: T < T+FYM < G+NPK2 < G+NPK1 < G. Similarly, the lowest abundance of soil culturable bacteriota was found in T and it increased in the following order: T < T+FYM = G+NPK2 < G+NPK1< G. Culturable bacteriota was identified using mass spectrometry (MALDI-TOF MS Biotyper). The most numerous species group was Bacillus, followed by Lactobacillus > Staphylococcus > Pseudomonas. The most frequently isolated species were Bacillus megaterium (16.55%), Bacillus cereus (5.80%), Bacillus thuringiensis (4.87%), and Bacillus simplex (4.37%). Positive relationships between SOM and soil culturable bacteriota were found in the G and G+NPK1 treatments. Temperature also affected soil culturable bacteriota in all soil management practices, most significantly in G+NPK1. Overall, the best scenario for the sustainable management of a productive vineyard is the use of grass strips.

Boswellia carterii, known as frankincense, is a fragrant medicinal plant. The essential oil from this plant is often used in traditional medicine or aromatherapy. Due to its positive properties, it has potential applications as an antimicrobial agent in medicine and the food industry. The aim of this study was to evaluate the antimicrobial, anti-insect, and antioxidant activities of frankincense essential oil (FEO). The composition of volatile compounds was determined by GC/MS, and the main components were found to be α-pinene (37.0%), α-limonene (19.8%), and p-cymene (6.3%). The antioxidant activity was evaluated with DPPH and ABTS methods with the resulting inhibition of 73.88 ± 0.35% of DPPH radical (6.27 ± 0.17 TEAC) and 97.09 ± 0.48% of ABTS radical cation (5.21 ± 0.07 TEAC). The antimicrobial activity was the strongest against Candida species with inhibition zones in the range of 38.00–44.00 mm and MIC 50 and MIC 90 values of 11.72 and 12.58 μL/mL, respectively. The inhibition activity of the vapor phase was the highest against G+ and G− bacteria growing on a carrot with inhibition ranging from 65.14 to 93.67%. The anti-insect activity against O. lavaterae was determined as 100% at 100% concentration and 50% at 25% concentration. The degradation of biofilm was tested with MALDI-TOF MS, and changes in the protein profile were observed.
