“…Soluble Potassium This potassium represents the dissolved ion in soil solution at any time and under conditions of field moisture and is not adsorbed on the surface of colloids and its percentage increases in the soil solution due to the conditions of hydrolysis or substitution by other cations, as the results Showed (0.005 to 0.272) Cmol.Kg-1.soil, In (table 4). It may be due to the increase in its organic matter content and the repeated succession of hydration and drying processes during cultivation, which affects the release of potassium From K-bearing minerals soluble potassium these results were in with (Shakeri and Abtahi, 2019) and Odyuo et al (2015) which showed that the values of potassium dissolved in the soil ranged between (0.023-0.0317) Cmol.Kg-1.soil for the surface and subsurface horizons of the soil. Siddiqua et al (2018) indicated in their study of (20) selected soil samples from different locations of nalgonda district of Telangana state chosen based on their difference in soil type and depth, practices management soil, and the nature of their use (0.173-0.031)…”

Quantity intensity parameters were used to evaluate the dynamics of potassium in soils under the management of different agricultural use. Sixteen soil samples were collected from Nineveh Governorate to study the forms of potassium relationship of different forms of in these soils, i.e., available, watersoluble, exchangeable, were ranged from (0.005-0.272),(0.486 to 1.252) and (0.749 to 2.355), respectively. In general, the quantity/intensity (Q/I) of K may serve as an index for the intensity and quantity of effective K supply to plants in soils. the quantity-Intensity relationship of Potassium was studied to quantify potassium release for the studied soils. results showed, potassium activity ratio (AR e K) is related to changes with labile potassium (±ΔK) at equilibrium and increased together with increasing potassium concentrations, and it is ranged between (3.91 and 24.21) 10-3 (mol.L-1) 1/2. The range of labile K + (K L) values is equal to (0.18-0.61) cmol. kg-1 , respectively, while the K + (PBC K) was from 21.78 to 45.93 cmol. kg-1 (mol.L −1) −1/2 , The Free energy in the (−ΔG) ranged from-0.79 to-0.53 kJ.mol-1 .and Gapon Selectivity Coefficient (k G) ranged from 0.93 to 1.65 (mol.L-1) 1/2. Therefore, this information may be used as references for potassium soil fertilization. The study provided more accurate information about the potassium dynamics of the soils and play a significant role in the behavior of potassium. The results of the statistical analysis showed a positive and significant correlation between potassium forms and some thermodynamic parameters of potassium and some soil properties, while the correlation was negative between these forms and CaCO 3 .

“…The high concentration of Ca 2+ for all the water bearing units can probably be due to water-rock interaction as most of the rocks contain mineral species such as calcite, gypsum, and anhydrite (Dhital, 2015). The low level of K + relative to Ca 2+ , Mg 2+ , and Na + may be due to the fact that it can easily be fixed by clay minerals (Shakeri and Abtahi, 2020). Dominance of HCO 3 − indicates chemical weathering inferred from silicate and carbonate weathering rocks present in the river basin (Nisha et al, 2021).…”

Inter Basin Water Transfer (IBWT) is a water resource stressor globally with negative environmental impacts. This study describes the major ions and hydrochemistry of the first ever ongoing IBWT from snow-fed Bheri River to rain-fed Babai River in Western Nepal. Water samples from 10 sites, five from each river system, were collected in HDPE bottles for major ions (Ca^(2+), Mg^(2+), Na^+, K^+, HCO_3^-, Cl^-, SO_4^(2-), NO_3^-, CO_3^(2-)) along with the estimation of pH, temperature and conductivity encompassing winter, spring, summer, and autumn in 2018. Ca^(2+)and HCO_3^- were the most dominant cation and anion, respectively, with 〖Ca-Mg-HCO〗_3 water type in both the river systems. Mann Whitney test revealed significant variation (p<0.05) between the two river systems with regard to Ca^(2+), Mg^(2+), HCO_3^- , and SO_4^(2-). Kruskall Wallis test revealed significant variations between seasons in pH, temperature, Na^+, K^+, and Cl^- in Bheri River system, and in pH, TDS, temperature, Na^+, K^+ , Cl^- and SO_4^(2-) in Babai River system. Carbonate weathering was the main mechanism of ionic sources with insignificant contribution from silicate weathering. Relatively higher concentrations of the major ions during the dry seasons probably indicate the dilution effect of monsoon. Higher concentrations of the ions in the Babai River system reflect the latter’s bedrock geology with susceptibility to erosion. With Nepal’s future plans of IBWTs and their environmental implications, this finding could be helpful in mitigating the negative consequences of IBWTs in the impact assessment and management of IBWT projects because of their implications on management of aquatic resources.

“…Rendahnya kandungan K dalam tanah yang dihadapkan dengan kebutuhan K oleh tanaman vanili yang relatif besar tanpa diikuti oleh pemupukan yang cukup dapat menyebabkan defisiensi dan mengganggu proses pembungaan vanili (La et al, 1998;Osorio et al, 2012;Diez et al, 2015). Kondisi ini diperparah oleh fiksasi K oleh mineral liat tipe 2:1 (Florence et al, 2017;Shakeri & Abtahi, 2019) serta kompetisinya dengan kation lain seperti Ca dan Mg pada kompleks jerapan tanah dan akar tanaman (Mitsui dan Ueda, 1963;Jacobsen 1993). Pemupukan K yang dikombinasikan dengan penambahan bahan organik dalam dosis yang cukup dapat meningkatkan pertumbuhan, pembungaan dan pembentukan buah pada vanili (Osorio et al, 2014)…”

Soil physical and chemical properties are the main factors that significantlyinfluence vanilla production. This study aimed to identify the soil’s physicaland chemical properties, determine the soil fertility status, and evaluate the soilsuitability for vanilla plants cultivated at three villages in Tinangkung UtaraDistrict. This research has been carried out at the long-term monoculture of thevanilla plantation. The soil fertility properties have determined based onphysical properties such as texture (pipete method) and chemical propertiessuch as pH, organic C content (Walkey and Black), P2O5 (olsen) and K2O(HCL25%), base saturation/KB dan cation exchange capacity/CEC ) NH4OAcpH7). The data then matched to PPT soil fertility and BBSDLP land evaluationcriteria for the vanilla plant. The result showed that the soil in the study sitehas clayey texture, neutral soil reaction, moderate KB and P2O5, and moderateto high CEC. On the other hand, the soil exhibited lower content of organic Cand K2O. Despite soil fertility status determined as low, the evaluation analysisresulted marginally suitable, which could be optimised to highly suitable.
