| Title : | THE INFLUENCE OF UNCONVENTIONAL MINERAL FERTILIZERS BASED ON THE PROCESSING OF K-MG ORES ON YIELD AND QUALITY OF SEED POTATO, AS WELL AS SOIL FERTILITY PARAMETERS |
| Abstract : | The results of the field study with traditional mineral fertilizers and unconventional one, based on the processing of K-Mg ores, on seed potato planting are presented in this paper. The efficiency and aftereffect of potassium fertilizers (KCl and the processing product from clay-salt sludge) on the NP background were studied. The technology for the production of new fertilizer from clay-salt waste (sludge) remaining as a result of potassium fertilizers production from natural K-Mg ores, was elaborated in Mining Institute, the division of Perm Federal Research Center. The resulting product, containing K, Ca, Mg and trace elements, which has the properties of fertilizer and ameliorant, has received the name the cinder of clay-salt sludge. The main processes in the technology are waste enrichment and subsequent high-temperature calcination of the enriched concentrate. As a result, the product, with the properties of multiple slow-release fertilizer was formed on a chloride-free basis. It is undesirable to use for potato fertilizers containing chlorine, so it is useful to expand the range of potassium fertilizers. The field trials with cinder were fulfilled on the experimental plots of Perm Agricultural Scientific Research Institute, the division of Perm Federal Research Center, in 2018-2020 years. The experimental scheme included treatments: control (without fertilizers), NP - background; NP + KCl and NP + cinder. Potassium fertilizers were used in autumn (basic application) and in spring (pre-planting application). No fertilizers were used in 2020. The influence of mineral fertilizers on yield and quality of seed potato, as well as soil fertility parameters were studied. The obtained results showed that the direct effect of unconventional fertilizer (cinder) with its pre-planting application was approximately equal to the effect of traditional potassium chloride fertilization, provided that the rates in the active substance were equal (yield in 2019 – 46.0 and 47.1 t-1 ha, respectively). The use of cinder did not have a significant effect on the quality indicators of potato tubers both directly in the year of fertilization and after the storage period. Cinder, in contrast to the standard KCl fertilizer, had a positive effect on the content of exchangeable potassium in the soil. Research with unconventional mineral fertilizers based on K-Mg ore processing wastes should be continued with an emphasis on the study of long-term action as a complex ameliorant |
