These two processes are called the carbon cycle "Biomass Energy Resources ". 2.b What are the types of plants used in Biomass? Many types of plants can be used in biomass. There are two main approaches to convert plants to energy: we can either grow plants for especially for energy uses, or using the waste of plants that are used for other things like making paper. Energy crops: The first type of plants used in Biomass is energy crops.
Soil – Lime Reactions The addition of lime to a soil initiates a two stage reaction. Short-term reactions show their effect right after the addition of lime, while long term reactions are accompanied by a period of time. The short-term effect of the addition of lime to a clay soil is to cause flocculation and agglomeration of the clay particles, as explained in Section 3.1 on fly ash stabilization, for cation exchange takes place between the metallic ions of the clay particles and the
Co is given to soybean (Glycine max) plants in pot culture by soil drenching method. Amount of Co in soil On average 1kg of soil contains 8mg of cobalt & by this amount it varies widely around the Earth from 0.1-70mg/kg. For healthy & productive soil amount of Co must be 1-2mg/kg. How does Co get into the soil It is not present on earth freely because of oxygen on atmosphere and chlorine in ocean. It occurs in soil naturally through two major sources 1.
The actual digestion started by H2O2 and in this step most of the organic matter were oxidized. After decomposition of the excess H2O2 and evaporation of water, the digestion was completed by concentrated H2SO4 at elevated temperature (330°C) under the influence of Se as a catalyst. In these digests total N was measured spectrophotometrically with a segmented-flow system (Auto-analyzer II, Technicon). Salicylicacid was added purposely to prevent loss of nitrate-N by coupling the nitrate to salicylic acid, a reaction which proceeds easily in the acid
Methylation is a product of complex processes that move and transform mercury. Atmospheric deposition contains the three principal forms of mercury, although inorganic divalent mercury (HgII) is the dominant form. Once in surface water, mercury enters a complex cycle in which one form can be converted to another. Mercury attached to particles can settle onto the sediments where it can diffuse into the water column, be resuspended, be buried by other sediments, or be methylated. Methylmercury can enter the food chain, or it can be released back to the atmosphere by volatilization.
Parameters such as pH, temperature are identified in situ. The amount of carbon storage and the humidity of soil are identified through laboratory test. The main focus of the study is on the carbon sequestration of soil. Other parameters such as pH, temperature is needed just to adjust the carbon reading. High value of carbon value indicates that the ecosystem can store large amount of carbon under the soil or
Summary The present study is concern with the assessing the effect of different mineral salts and varying urea concentration on Aspergillus sp. growth and enzyme production under solid-state fermentation (SSF). Aspergillus versicolor was screened for the production of enzyme by SSF method. The fungus was placed on potato-dextrose agar (PDA) medium, subcultured them once in a week and then incubates at temperature of 30⁰C. The role agro-wastes in the solid-state fermentation (SSF) method are as substrate.
It is believed that between two and four billion years ago, the first ancient and microorganisms came about in Earth's primitive seas. These bacteria could fix nitrogen, in time multiplied and as a result released oxygen into the atmosphere (Willey, 2011). This release of oxygen led to more advanced microorganisms (Lynch, 1983). Microorganisms in soil are important because they affect the structure and fertility of different soils. Soil microorganisms can be classified as bacteria, actinomycetes, fungi, algae, and protozoa.
Growth & Development of Plants The biogeochemical cycles include the uptake of nutrients of inorganic elements by the plants through their roots in solution from the soil where these inorganic elements derived from sedimentary phase, are stored. The decomposition of leaves, plants & animals & their conversion into soluble inorganic form are stored into soil, which helps in the growth & development of plants. Decomposition are converged into such elements which are easily used in development of plant tissues & plants growth by biochemical processes, mainly photosynthesis. 5. Ecosystem productivity It refers to the rate of growth of energy or organic matter per unit time by autoharps at tropic level are through the process of photosynthesis with the help of solar energy.
Soil formation Soil is produced through the disintegration of parent rock by the process of weathering i.e. physical and chemical weathering which therefore lead to the decomposition and disintegration of rock into soil (Chen et al., 2000).Soil forming factors may later combine with the weathered material and transform it to produce a wide range of soil types. Soil produced may thereafter combine with organic matter to give an ideal soil type. Soil formation is an outcome of a wide range of conditions (Van Breemen and Buurman 2002) Factors affecting soil formation Soils are formed through the interaction of five major factors. Nature of the parent material/parent rock Climate Living organisms Relief Time Nature of the parent material
