The spatial dispersal of acid and alkaline phosphates activity in forest soils appears to be controlled by position in the landscape and its soil microbial density. Soil bacteria expressively produced significant level of acid phosphatase in the investigation.The variety of acid phosphatase activity (8.25-37.55 />-nitrophenol.g"soil.h") noted higher and followed by alkaline (0.78-7.15 p-nitrophenol.g-soil.h" ), correspondingly. Acid and alkaline phosphates were exist in both of soil of natural as well as for non-natural forest soil landscape, with the value (po/o=0.6210) of correlation are 0.6889 and 0.6532, respectively. Phosphate Solubilizing Bacteria (PSB) average density in natural forest soil equivalent to 0.61xl0Ã colony forming unit (cfu) and total bacteria is 160xl0 cfu, while the PSB in non-natural forest soil is 7.75xl0 cfu and total bacteria is 48.25x10 cfu. Concerning to the forest environment as soil bacteria inhabitants of PSB, there were significantly difference of PSB population in natural and non-natural landscape forest. Forest environment is negatively affect the soil enzymes activities under Pinus maritima and Caliandra calothyrsus as the lowest activities, and to the highest ones under the Schima wallichii and Eucalyptus saligna vegetation.

Pesticide Residue was Affect Bacterial and Fungal Population in the Greenhouse Soil Condition. Bacterial and fungal inhabitants were examined through agriculture soil samples. Survival of microorganism in soil was important to evaluate the mineralize process. In the greenhouse experiment, bacterial and fungal population noticed as essential assessment in soil healing with long lasting pesticide (A-soil) after the soil treated with powdered rice straw as organic matter amendment, toxic degrading bacterial as inoculants, and the both of those mixed treatments. That residue implication also assessed to B-soil (as free pesticide soil) then revised with pesticides, and also treated as followed for A-soil. Potential degradation of indigenous microorganism examined all through as setting of control (B-soil) to recognize of its original population.Those of treatments evaluated through microbial survival along 12 weeks incubation in green house environment. Bacterial and fungal populations was affect to become fluctuated along with incubation period as due to the treatments. Bacterial inhabitant was considerably higher compared to fungal population. Correlations were significantly difference with bacterial (p = 0.6654) as well as fungal (p = 0.9029) population in A-soil evaluated to B-soil habitats since the mixed treatments present to both of the soil (p0.005 = 0.6310). Organic matter alteration and certain microbe input was needed in soil contain pesticide, because at the same time the survival of microbes possibly mineralized organic matter, as well as the pesticide residue.

Organic farming basically work on improving organic soil substrate which give impact to plant growth promoting bacteria. On the other hand, the use of agrochemicals leave chemical residues in the soil. In an effort to get the quality of organic matter and selected microbes as a biofertilizer material, this research had been done. Half ripe composting (HRC) process of organic substrate was utilized to enrich soil containing agrochemical residue, while ripe compost (RC) substance amended to soil free residue. That compost was used in broccoli cultivation. Microbial degrading pesticide was added to compost as biofertilizer formula. Even though plant biomass and the yield of flower was unclearly affected, but moreover the HRC application as due to â??semi-on-site-compostingâ? practices in soil containing agrochemical residue would cut off compost processing time. Soil microbial activity measured through soil respiration, urease and phosphomonoesterase indicated that the value was lower in samples collected from the soil free residue compared with soils containing residues. Utilization of chicken manure resulted in the availability of high nitrogen compounds and causing imbalance absorption by plants, compared with the use of HRC and RC in this study.Â Keywords: soil respiration, phosphatase, urease, Brassica oleracea L.Â

Growth Capacity of Soil Bacteria Isolates Obtained from Estate Area from Media Containing Propoxur and Carbaryl. Isolation actions have been carried out with three soil samples derived from soil estate of pine apple, sugar cane, and banana in Lampung area, Southern Sumatra. The isolates were grown in the selected media containing carbaryl insecticide, and herbicide of diuron and bromocyl. The highest and vigorous growth isolates have gathered from threedifferent soil samples, and subsequently named GGPC, GM, and NTF isolates. Furthermore, those isolates were studied through the growth rate in the media containing propoxur and carbaryl in the nutrient rich liquid (NB) and compared to limited mineral (MM). All of the isolates grew faster against pesticides in the liquid medium of NB compared to MM. High correlated value among parameters nurtured as due to bacterial population and those processes were not affected by media composition. The GM isolate showed similar pattern during propoxur decrease along with incubation even though the rate of pesticide elimination from the media was higher in the rich nutrient liquid media (NB) compared to MM.Keywords: microbe isolate, pesticide, propoxur, carbaryl
