Soil Organic Matter and Aerobic Respiration,n energy source to reduce inorganic carbon of CO. to organic carbon of simple sugars. Solar energy is transformed by photochemical reactions in plant cells to chemical energy of chemical compounds. Oxygen is released as a by-product. The summary reaction is . Chemoautotrophic bacteria also reduce ca

,Soil Organic Matter, Anaerobic Respiration, and Oxidation—Reduction,ic animal production are biologically mediated oxidations and reductions. Photosynthesis is a well-known reduction reaction; inorganic carbon in carbon dioxide is reduced to organic carbon in carbohydrate with the capture of energy. Aerobic respiration is an oxidation reaction in which carbon in org

Relationships to Aquatic Animal Production,ch, in turn, influence plant productivity. In extensive pond culture, aquatic animal production is the culmination of the food web that has its base in plant production (Fig. 5.1). Plants also are the primary source of dissolved oxygen in most ponds, but plant respiration and plant residues also exe

Pond Bottom Management,l condition in new ponds sometimes is unsatisfactory, and the condition of pond soils may deteriorate over time in response to demands imposed on them by aquaculture. Some pond management schemes cause less degradation of soil condition than others, and a few treatments are available for improving s

Pond Bottom Soil Analyses,an be found in most countries. Analyses usually are done on a fee basis. Although analyses can be made in soil testing laboratories, aquaculturists must know how to collect and prepare samples for delivery to laboratories. Some aquacultural workers may want to make their own soil analyses. Researche

Relationships to Aquatic Animal Production,e light transmission through the water and adversely impact plant productivity and photosynthetic oxygen production. Sedimentation can smother aquatic organisms and destroy fish nesting sites. Suboptimal soil texture and pH may limit production of benthos, which is the food of many aquatic animals.
