Indonesia has a wide area of acid-dry land with potential food crops, especially soybeans. The study was conducted to determine the effect arbuscular mycorrhizal fungi (AMF) as seed coat soybean on ultisol, applied various doses lime. in Ultisols Kuranji Village, District, Padang City, West Sumatra, Indonesia. experiment arranged split-plot design. main plot dose CaCO3 lime two levels, namely 0...

Each factor consists 4 ...

Hawaii is the only state in the USA that grows, processes, and roasts coffee. Coffee processing, however, poses some challenges. One is the processing water, which must be treated, and should be re-used. We surveyed and collected several coffee processing water samples, both influent and effluent, from four small-scale (2-5 ha) coffee farms in Kona on Hawaii (Big Island), and from a large (1200...

A pplication of reverse micelles for the synthesis of nano-sized calcium carbonate particles in different solvents (cyclohexane, decane and heptane) has been investigated. The effect of the mole ratio of water-to-surfactant (R) and type of solvent has been studied on the size and nature of the carbonate particles. The results indicate that an increase in water-to-surfactant ratio results in a l...

The use of sintered CaO as a refractory material is not uncommon. Refractory material based on lime as the lining of the Bessemer converter was applied for the first time in 1875 in order to carry out desulphuring and dephosphoring of the molten pig iron. Due to interaction of the porous burned CaO with the atmospheric moisture during dead time followed by damage and disintegration of this case...

Soil organic carbon (SOC) forms the largest terrestrial (C) pool, which is regulated by complex connections between exogenous C input, microbial activity, and SOC conversion. Few studies have examined changes in natural abundance due to activity after inputs karst lime soils China. In this research, 13C isotope tracer technique was employed investigate priming effect of on typical soil (0~20 cm...

ule formulation are similar to those of secondary root formation (Gresshoff, 1993). Improvements in image Acidic soils can reduce the nodulation of forage legumes. Studies analysis technology allow researchers to assess the efwith a Gilpin series silt loam (fine loamy, mixed mesic, Typic Hapludult) from New, WV, were conducted to determine the effects of lime fects of soil conditions on specifi...
