Combining deep soil tillage systems with lime application is a potential strategy for improving the sugarcane production in acidic soils. The authors evaluated influence of and on performance attributes, including acidity. A field study clayey-textured Rhodic Hapludox was conducted two growing seasons utilizing 3 × 2 factorial scheme comprising three without lime: conventional system (CT), stri...
Many hydrogenotrophic methanogens use either H2 or formate as the major electron donor to reduce CO2 for methane production. The conventional cultivation of these organisms uses H2 and CO2 as the substrate with frequent replenishment of gas during growth. H2 is explosive and requires an expensive gassing system to handle safely. Formate is as an ideal alternative substrate from the standpoints ...
The Gram-negative bacterium Klebsiella planticola represents an interesting host organism for the production of biotechnological products. Microbial processes – especially those of aerobic cultivation – lead to the generation of considerable amounts of biomass, thus lowering the product yield. These are the reasons for studying methods for the recycling of biomass from K. planticola. It will be...
The usage amount of medicinal plant rapidly increased along with the development of traditional Chinese medicine industry. The higher market demand and the shortage of wild herbal resources enforce us to carry out large-scale introduction and cultivation. Herbal cultivation can ease current contradiction between medicinal resources supply and demand while they bring new problems such as pestici...
Soil cultivation is commonly used to manage organic matter (OM) accumulation in golf course putting greens. Our objectives were to determine: (i) if hollow-tine cultivation is more effective than solidtine cultivation at managing OM and water infiltration, (ii) if venting methods are effective at managing OM and water infiltration, and (iii) if venting alters or interacts with effects of earlyo...
During the sudden decrease in RNA synthesis in Streptomyces aureofaciens, i.e. around the 6th hour of cultivation, synthesis of adenosine and guanosine tetraphosphates and pentaphosphates begins. The synthesis of these nucleotides is highest during the onset of chlortetracycline production, around the 20th hour of cultivation and continues. During this phase of growth of S. aureofaciens, RNA an...
Levels of opium poppy cultivation in Afghanistan’s provinces and districts rise and fall depending on a range of factors that are not well understood. Declines in cultivation are often attributed to the political commitment of the provincial and local authorities and the role of information campaigns, while the underlying power and economic dynamics that drive these changes receive little atten...
This paper takes a comparative approach to early farming, arguing that bioarchaeological work on Neolithic Europe can inform understanding of earlier cultivation and herding in the Near East, where the ‘package’ of crops and livestock emerged in the PPNB period. Evidence for intensive cultivation (‘garden agriculture’) integrated with small-scale herding is outlined for south-east and central E...
