“…3). The prolonged effect of fertilizers is probably associated with the synergistic interaction of fertilizers and the microbiological component of the preparation, as well as the biosolubization of hard-to-reach forms of potassium by bacteria of the genus Bacillus, which was previously identified by researchers [11,16,17].…”

The crucial trend in the intensification of gardening is the use of agrochemicals, including the systematic application of mineral fertilizers, regulated by the production flow chart of fruit products. Technological pressure on the soil causes aggravating the ecological problem of loss of the fertility level in the conditions of the orchard monoculture. The search for sustainable and environmentally effective approaches to solving the problem of managing fertility factors is aimed at studying the effects of biological and biomodified fertilizers. The changes in the main indicators of the effective fertility of the structural-metamorphic agrosem in the conditions of the orchard monoculture with the application of biomodified organo-mineral fertilizer were studied in dynamics. The prolonged effect of organo-mineral fertilizer on increasing the content of the main indicators of effective fertility in the soil was determined six years after application. The use of biomodified organo-mineral fertilizer in the orchard fertilization system is considered as an element of an integrated strategy for the management of orchard soil fertility.

“…Potassium is needed in plants for metabolisms such as cell synthesis, enzyme production activities, protein, cellulose, and vitamins. Also, potassium can increase plant resistance to abiotic and biotic stress [26]. Potassium (K) also plays a role in regulating the transport of water and nutrients through the xylem.…”

Maize (Zea mays L.) is a functional food source in Indonesia after rice and wheat. Increasing maize productivity can be done by developing a proper environment and nutritional availability during cultivation. The use of endophytic bacteria as biofertilizers is one prospective approach in reducing the synthetic fertilizers in the soil, and improving the absorption of macronutrients, such as nitrogen, phosphate, and potassium, as well. This study aimed to obtain phosphate solubilizing bacteria (PSB) and potassium solubilizing bacteria (KSB). The samples of maize leaves, stems, and roots were isolated using a serial dilution method and selected on a Pikovskaya (PKV) and Aleksandrov medium. A total of 10 PSB isolates were obtained from PKV selective agar media. The highest density was obtained in the root (8.3x10 5 CFU.mL-1), stems (5.7x10 5 CFU.mL-1), and leaves (4.6x10 5 CFU.mL-1), respectively. Meanwhile, the diversity index of the PSB ranges from 0.7 to 0.78, indicates that the diversity index is high. Four isolates from PSB (AP1.3, AP3.1, AP1.2, and AP1.4) were selected as KSB because of the clear zone formed in Aleksandrov's medium. The highest production of phosphate and potassium was obtained by AP1.3 with value 12.11 µg.mL-1 and 8.38 µg.mL-1 at 72h and 15d, respectively. Therefore, these isolates potential to be used as an organic fertilizer (biofertilizers).

“…Potasyum çözen bakterilerin potasyumun bağlı bulunduğu minerallerden potasyumun serbest kalmasında etkili olan çeşitli asitler salgıladıkları bilinmektedir. Bashir et al (2017), tarafından bakteri strainlerinden Serratia marcescens'in sitrik ve laktik asit; Chryseobacterium türlerinin sitrik asit; Pseudomonas türlerinin glukonik, laktik, suksinik, formik ve malik asit; Enterobacter türlerinin ise malik ve glukonik asit ürettikleri tespit edilmiştir. Bu araştırmada pozitif sonuç veren strainlerin de çeşitli organik asitler üreterek besiyerinde berrak bir zon oluşumu ile ortam içerinde bulunan mica'yı çözdüğü düşünülmektedir.…”
