| Summary: | Background. The interaction between plant nutrients can lead to antagonistic or synergistic results that affect the effectiveness of nutrient use. Knowledge of nutrient interactions can guide the development of fertilizers and optimize fertilizer application strategies to achieve high yields and high nutrient efficiency.
Purpose. To study the effect of the use of organic fertilizers alone or in combination with chemical fertilizers on the accumulation and distribution of Fe, Mn, Zn, and Cu in the organs of rapeseed plants during the green pod phase.
Materials and methods. The study was conducted in 2022-2023 at the educational and experimental site of I.A. Bunin YSU in the Lipetsk region. The soil cover of land use is represented by leached chernozem of medium loamy granulometric composition. The scheme of the experience is represented by four options: 1. Control; 2. Mushroom soil 30t/ha (28 kg N); 3. Mushroom soil 30t/ha+ N70 (80 kg N); 4. Mushroom soil 30t/ha + N140 (130 kg N). The mineralization of the samples was carried out by dry salinization according to GOST 26657-85. The mobile forms of metals were extracted using 1% HNO3. The mathematical processing and interpretation of the primary data were carried out using classical statistical methods using the Statistica software package.
Results. The rapeseed root system has become a Fe hub. Stable iron metabolism in the root system is explained by the development of effective mechanisms of iron absorption by plants and its strict regulation. It was found that increasing the incoming nitrogen is more effective for increasing the concentration of zinc in the vegetative and generative system of the plant than in the root. Copper in rapeseed is regulated by the nitrogen balance and the doses of fertilizers studied in the experiment, which are optimal and do not show ion antagonism. The values presented in the experiment indicate the plant's ability to accumulate bioavailable Mn in terrestrial plant tissues.
Conclusion. In the course of the presented study, it was revealed that the fertilizers recommended in the experiment and their doses positively affect the synergy and distribution of vital trace elements in rapeseed organs. Their concentration does not reach toxic values.
