“…Keberadaan mineral liat tipe 2:1 (kelompok mineral monmorilonit, smektit, vermikulit) yang berada dalam jumah relatif banyak dapat dideteksi secara parsial melalui nilai KTK liat (Tabel 3;Tabel 5;RePPPRoT 1983;Schulze 1989;Brown dan Nadeau, 1984;Supandjono & Haryono 1993). Kondisi serupa juga dilaporkan oleh peneliti lain pada tanah yang berkembang dari formasi geologi yang sama (Rezaei et al, 2012;Moghimi et al, 2013;Santos et al, 2017;Mesrar et al, 2020).…”

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.

Total viable counts of bacteria and bacterial diversity of the different soil samples from three different localities in Sharq EL-Neel region: Soba, AL-Aelafoon and Um Dawan Ban sub-regions were carried out. Soil physical and chemical characteristics (pH, EC,SP,solublecations: Na, K, Ca, Mg and anion P, organic carbon, total nitrogen and soil texture)in each studied sub-regions were measured. Qualitative analysis of microorganisms isolated from the studied soil samples reveal a total of thirteendifferent species of bacteria, of which two are unidentified. The ten species are classified under Bacillus genus. In Sharq EL-Neel regionsoil samples, total bacterial counts ranged from 9.5 × 10 4 cfu g -1 to 1×10 3 with a mean of 4×10 3 cfu g -1 . The quantitative data on microbial population recorded in the present study was analysed using two diversity indices. High Shannon-Weiner diversity Index value for bacteria was obtained in ALAelfoon sub-region (1.79361), whereas high Simpson's index value was obtained in Um Dawan Ban sub-region (2.80).ActinomycesActinomyces spp. and Streptomyces spp. Where the most abundant microorganisms identified in the three subregions. Total bacterial count in Soba soil was positively correlated with pH (r= 0.0194) and sand (r= 0.3205); the total bacterial count in AL-Aelafoon soilwas positively correlated with EC (r= 0.1062), clay (r= 0.3816), silt (r= 0.1936), SP (r= 0.9302), K (r= 0.6252), Ca (r= 0.0015) and Mg (r= 0.1556), whereas the total bacterial count in Um Dawan Ban soil was positively correlated with clay (r= 0.2614), silt (r= 0.0216), SP (r= 0.565), K (r= 0.9645), P (r= 0.0197), Ca (r= 0.7377), Mg (r= 0.0267), N (r= 0.5215) and O.C (r= 0.3214). There were obvious differences in correlation coefficients among the selected criteria (46 % from the total number of correlation coefficients were positively correlated between bacterial counts and soil physico-chemical properties whereas 54% from the total number were positively correlated between plant type and bacterial counts).

Bacterial diversity and total viable counts of bacteria of the different soil samples from two different localities in Omdurman north region-Karary and Khor Omer sub-regions-were carried out. Soil physical and chemical characteristics (pH, EC, SP, solublecations: Na, K, Ca, Mg and anion P, organic carbon, total nitrogen and soil texture) in each studied sub-regions were measured. Qualitative analysis of microorganisms isolated from the studied soil samples reveals a total of more than eight different species of bacteria, of which two are unidentified. The six species are classified under Bacillus genera. In Omdurman north region soil samples, total bacterial counts ranged from 7.5 × 10 3 cfu•g −1 to 1 × 10 4 with a mean of 4 × 10 4 cfu•g −1 . The quantitative data on microbial population recorded in the present study were analysed using two diversity indices. High Shannon-Weiner diversity index value for bacteria was obtained in Khor Omer sub-region (1.71261). Actinomyces spp. and Streptomyces spp. were the most abundant microorganisms identified in the two sub-regions. Total bacterial count in Karary soil was positively correlated with EC (r = 0.3868), clay (r = 0.1412), sand (r = 0.5891) and K (r = 0.0265) and negatively correlated with pH, silt, SP, Na, P, Ca, Mg, N and OC whereas the total bacterial count in Khor Omer soil was positively correlated with EC (r = 0.3973), clay (r = 0.1966), silt (r = 0.2116), Ca (r = 0.6733), Mg (r = 0.586) and OC (r = 0.2368) and negatively correlated with pH, sand, SP, Na, K, P and N. There were obvious differences in correlation coefficients among the selected criteria (37% of the total number of correlation coefficients were positively correlated between bacterial counts and soil physico-chemical properties whereas 63% of the total number were positively correlated between plant type and bacterial counts). The formulation of an appropriate national strategy in biotechnology should constitute an important, initial step towards the utilization and industrialization of microorganisms. The development of molecular techniques of microbial identification, coupled with traditional methods is promising areas for continued research.
