“…This behavior documented before in the application of vermicompost, zeolite, and a combination of both to release potassium and in another study about the release of potassium from soil amended with clinoptilolite zeolite and corn stalk charcoal. , Furthermore, the release of potassium from zeolite F was derived from feldspar powder . Limestone soils (chloritic and kaolinitic) also exhibit this mechanism …”

“…92 Limestone soils (chloritic and kaolinitic) also exhibit this mechanism. 93 A similar pattern was observed in previous studies with soils. 94 According to the literature, in soils, the faster release at the beginning of the process is normally related to the exit of the cations from the surface sites.…”

“…The evaluation of K kinetics is based on the extraction of K at different times. Based on previous research, the CaCl 2 method is recommended for determining the rate of K release in calcareous soils [29][30][31]. In the current study, K was extracted by 0.01 mol L −1 CaCl 2 after incubation (25 ± 1 • C) periods of 1, 3, 7, 14, 21, 30, 50, and 80 days [30].…”

Arid degraded soils have a coarse texture and poor organic matter content, which reduces the activity of microorganisms and soil enzymes, and thus the soil quality, plant yield and quality decrease. Potassium solubilizing bacteria (KSB) have been suggested to increase the activity of soil enzymes and increase the release of potassium from natural K-feldspar in the arid degraded soil, and thus potentially reduce the rates of the application of chemical fertilizers. Field studies were conducted for three successive growing seasons in an organic farming system to investigate the effects of K-feldspar and KSB (Bacillus cereus) on K release, soil fertility, and fruit yield of mango plants (Mangifera indica L.). The maximum growth of mango plants was found in the treatments inoculated with KSB. KSB increased soil available N, P, K, and the activity of dehydrogenase and alkaline phosphatase enzymes by 10, 7, 18, 54, and 52%, respectively. KSB increased the fruit yield of mango by 23, 27, and 23% in the first, second, and third growing seasons, respectively. The partial (up to 50%) substitution of chemical K-fertilizer with K-feldspar gave fruit yield and quality very close to that fertilized with the full chemical K-fertilizer. The release rate of K (over all the treatments) varied between 0.18 and 0.64 mg kg−1 of soil per day. KSB significantly increased the K release rate. The application of chemical K-fertilizer gave the highest K release, while substitution with K-feldspar reduced the release of K. Natural K-feldspar contains 8.2% K but is poorly soluble when applied alone. KSB increased the soil quality parameters and enhanced the growth and quality of mango fruit. The fruit yield of mango, under KSB inoculation and fertilization with different K sources, ranged between 9.14 to 17.14 t ha−1. The replacement of 50% of chemical K-fertilizer with natural K-feldspar caused a decrease in the fruit yield by 17, 8, and 2.7% in the first, second, and third years, respectively. The substitution of chemical K-fertilizer with K-feldspar up to 50% with KSB is a good strategy to reduce the excessive use of chemical K-fertilizer. B. cereus and natural K-feldspar have the potential to improve soil health and mango plant productivity in low fertile arid soils.

“…For all soils, the slope derived from the power function was less than one, indicating that the K-release rate decreased over time [ 110 , 111 ]. The variabilities in K release among the soils could be ascribed to the differences in types of clay minerals, contents of clay and silt, and climate conditions [ 115 ]. Besides [ 116 ], revealed that soil available K is primarily regulated by the rate of K released into forms suitable to be taken up by plants.…”
