“…For apple orchards grown in the climatic conditions of the Central Russian Upland, a significant effect of meteorological conditions and tree productivity on the level of mineral forms of nitrogen in the soil has been shown [11,12]. The same factors have a significant impact on the Nmin dynamics in the soil of young sour cherry orchards entering fruiting [13,14].…”

The aim of the investigation was to research the mineral nitrogen (Nmin) behavior in loamy haplic Luvisols of orchards located in the forest-steppe zone of the Central Russian Upland. The seasonal dynamics of N min (ammonium + nitrates) was studied during the growing seasons of 2018 and 2019 in field experiments with apple and sour cherry. Fertilizers were applied annually in spring at doses increasing from N30K40 to N120K160. The most important factors influencing the nitrogen dynamics were meteorological conditions, productivity of trees, peculiarities of nitrogen uptake by the studied crops. Fertilization of orchards with nitrogen contributed to an increase in Nmin content by 1.5 … 5 times, depending on the dose. The dynamics of Nmin in the soil of fertilized and unfertilized plots was similar and depended on the biological features of the crops: the lowest indicator’s level in the soil under sour cherry was in July during fruit ripening, while in the apple orchard a low nitrogen content was noted in August. Studies have shown that in the climatic conditions of the Central Russian Uplands, loamy haplic Luvisols without additional application of nitrogen fertilizers can provide a favorable level of nitrogen nutrition for apple and sour cherry trees in the first years of fruiting.

The purpose of the research was to evaluate the changes in the agrochemical properties of the sour cherry orchard soil after the permanent soil fertilization with urea and potassium sulfate. The field experiment was conducted during 2017-2021 in the soil and climatic conditions of the Central Russian Upland (Oryol region). ‘Turgenevka’ sour cherry trees grafted on the rootstock V-2-180 were planted in 2015 at a distance of 5x3 m. The soil of the orchard is loamy Haplic Luvisol with the following parameters: pHKCl - 5.8, organic matter content - 2.8%, available phosphorus - 383 mg/kg, exchange potassium -120 mg/kg, alkali-hydrolysable nitrogen - 108 mg/kg. Experimental scheme: 1. Control (no fertilizers); 2. N30К40; 3. N60К80; 4. N90K120; 5. N120K160. Fertilizers were applied once a year in early spring. The annual use of fertilizers in N90K120 dose or more contributed to an increase in the reserves of mobile phosphorus, exchange potassium, and alkali-hydrolysable nitrogen in the orchard soil, but did not have a stable effect on the tree productivity. At the same time, there was an increase of soil acidity and loss of exchange calcium under the influence of fertilizers, which indicates the beginning of degradation processes.

Sour cherry (Prunus cerasus L.) is one of the most important fruit crops in Poland and ‘Łutówka’ is the dominant cultivar in commercial orchards. The experiment was carried out in 2007–2013 in three orchards; in each of them, three levels of fertilization were applied: 0 N kg ha−1, 60 kg N ha−1, and 120 kg N ha−1. The activity of dehydrogenase and protease in the soil was studied depending on nitrogen fertilization. The abundance of soil microorganisms was assessed: bacteria, fungi, actinomycetes, and nitrogenous bacteria (Azospirillum and Azotobacter) in the years during the experiments carried out with fertilization of 60 kg N ha−1 in all orchards. The enzyme activity of dehydrogenases increased after the use of 60 kg N ha−1 from 3.8 to 6.7 (cm3 H2 24 h−1 kg−1 DW soil), but a further increase in the dose to 120 kg N ha−1 caused a decrease in activity to 5.1 (cm3 H2 24 h−1 kg−1 DW soil). The activity of proteases was dependent on nitrogen fertilization, but to a large extent it was related to the course of climatic conditions. There is no relationship between the growth and the activity of proteases. The yield and selected quality parameters of the cherry fruits were associated with both dehydrogenases and proteases. The use of lower doses of nitrogen fertilizers allows for maintaining biological balance in the soil and a more efficient use of nutrients, contributing to less environmental pollution.
