Beneficial microorganisms play a key role in the availability of ions minerals in the soil and use Randomized Complete Block Desing ( R.C.B.D ). The objective of this paper to the study effect of the of biofertilizer and miniral treatments on availability of NPK for crop corn zea mays L.Two types of biofertilizer are Bacterial Bacillus subtilis and Fungal Trichoderma harianum. Three levels of potassium fertilizer are (2.9533, 0.4000 and 2.9533). A field experiment in fall season of 2018 Has been conducted in silty clay loam soil. The experimental Results indicated that Bacillus and Trichoderma inoculation separately or together Have made a significant effect to increase in the availability of N P K in the soil compare to other treatments. The grain yield is where (2.9533, 0.4000 and 2.9533) of bacterial and fungal bio-fertilizer and potassium fertilizers respectively as compared to the control.

This research carried out in Huong Vinh commune, Huong Tra town, Thua Thien Hue province aimed to identify types of land use and soil characteristics. Results showed that five crops are found in Huong Vinh commune including rice, peanut, sweet potato, cassava and vegetable. There are two major soil orders with four soil suborders classified by FAO in Huong Vinh commune including Fluvisols (Dystric Fluvisols, Gleyic Fluvisols and Cambic Fluvisols) and Arenosols (Haplic Arenosols). The results from soil analysis showed that three soil suborders including Dystric Fluvisols, Gleyic Fluvisols and Cambic Fluvisols belonging to Fluvisols were clay loam in texture, low pH, low in OC, total N, total P2O5 and total K2O. Meanwhile, the Haplic Arenosols was loamy sand in texture, poor capacity to hold OC, total N, total P2O5 and total K2O

Gempa bumi adalah suatu peristiwa bergetarnya bumi akibat pelepasan energy di dalam bumi yang di tandai dengan adanya patahan lapisan batuan pada kerak bumi. Energy yang di hasilkan di pancarkan ke segalah arah berupa gelombang gempa bumi sehingga efeknya dapat di rasakan sampai ke permukanaan bumi, serta seringkali menimbulkan kerugian dan kerusakan pada bangunan. Penelitian ini dilakukan di desa Erie yang terletak di kecamatan nusaniwe kota ambon, penelitian ini dilakukan bertujuan untuk mengetahui fase – fase gelombang dan indeks kerentanan seismik. Pengambilan data dilakukan dengan menggunakan seismograf TDL 303S pada 6 titik pengukuran. Hasil pengukuran mikrotremor di analisis menggunakan metode Horizontal to Vertical Spectar Ratio ( HVSR) untuk memperoleh nilai frekuensi dominan (f0) factor amplikasi (Ao), sehingga nilai kerentangan seismic (Kg) dapat di tentukan. Dari hasil penelitian ini menunjukan bahwa nilai frekuensi dominan (f0) 0.646 Hz sampai 9.531 Hz, nilai amplikasi (Ao) 0.977 sampai 1.559, dan nilai indeks kerentanan seismik diperoleh 0.233 (Kg) samapai 2.113 (Kg), dan dari hasil pengolahaan data juga di peroleh nilai priode dominan dari setiap titik pengukuran, sehingga dari nilai priode dominan tersebut menunjukan bahawa pada titik pengukuran 1,5 dan 6 dapat di kategorikan sebagai sendimen yang lunak dan tersusun atas batuan Alluvial, yang terbentuk dari sendimen delta, toposoil, lumpur dengan kedalaman 30 m atau lebih dan pada titik pengukuran 2,3 dan 4 dapat di kategorikan tersusun atas batuan alluvial dengan kedalaman 5 m. terdiri dari sandy-gravel, sandy-hard clay,loam. Dengan demikian desa Erie tidak tergolong daerah yang rawan merusak bangunan.

Negative Effect

This study used laboratory experiments to compare the effects of coal tar creosote on the activity of oxidoreductive enzymes in sandy loam, loamy sand and sandy clay loam soils. Different amounts of coal tar creosote were added to soil samples as follows: 0 (control), 2, 10 or 50 g kg–1 dry matter. The activity of soil dehydrogenases (DHAs), o-diphenol oxidase (o-DPO), catalase (CAT), nitrate reductase (NR) and peroxidases (POX) was determined. Contamination of soil with coal tar creosote affected oxidoreductase activity. Oxidoreductive enzyme activity following soil contamination with coal tar creosote was in the following order: DHAs > CAT > NR > POX > o-DPO in loamy sand and in sandy loam; and DHAs > POX > CAT > NR > o-DPO in sandy clay loam. The index of soil oxidoreductive activity (IOx) introduced in this study confirms the negative effect of coal tar creosote on oxidoreductase activity in soil. DHAs were the most sensitive to the contamination of soil with coal tar creosote. Moreover, the greatest changes in oxidoreductase activities were observed in loamy sand. Knowledge of the mechanism underlying the effects of coal tar creosote on oxidoreductive processes may enable development of a method for the bioremediation of polycyclic aromatic hydrocarbon-contaminated soils.

This study was aimed to determine the changes in kefir samples (CK and GK) made from cow’s and goat’s milk during frozen storage. The CK and GK samples were first stored at +4 °C for 14 and 21 days. Thereafter, all the samples were frozen at –35 °C for 24 h and kept at –18 °C for 45 days. There was no significant change in the fat, protein, acidity and pH values in both samples during the storage. The values of viscosity, WI and C* were higher in the CK samples while the syneresis value was higher in the GK samples throughout the frozen storage. The microorganisms ( Lactococcus spp., Lactobacillus spp., Leuconostoc spp., total mesophilic aerobic bacteria and yeasts) found in kefir made from goat's milk were more affected from the frozen storage. In both samples, the changes in organic acids and volatile flavor components were not significant during frozen storage, except acetic, citric and oxalic acids and acetaldehyde in GK sample. In addition, CK samples were preferred sensorially more by the panellists during frozen storage.
