The rate at which soil changes under the influence of man's activities are so fast and often negative that this degradation needs urgent attention. Healthy soil includes not only the physical particles making up the soil, but also adequate pore space between the particles for the movement and storage of air and water. This is necessary for plant growth and for a favourable environment for soil organisms to live. Compaction occurs when soil particles are pressed together, thereby reducing the amount of pore space. Most farmers are aware of compaction problems, but the significance is often underestimated. Compaction effects on crop yield can be a significant factor in today's farm economy with a specific reference to tobacco. Thus in order to understand the causes, effects and impacts of soil compaction, ITC limited - Agri Business Division –ILTD undertook a comprehensive study in Mysore region (India) to diagnose the extent of soil compaction in farms and evaluate the impact of subsoiling in breaking the compaction layers.</p></div>","PeriodicalId":8107,"journal":{"name":"APCBEE Procedia","volume":"8 ","pages":"Pages 287-292"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.apcbee.2014.03.042","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82146957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results indicated that all liming materials tested could be classified as supplemental source of calcium and magnesium and caused an increase in soil pH, soil Ca and Mg, and base saturation levels, whereas aluminum saturation decreased. Dolomite, calcite and quartz are major minerals. Cu, Fe, Mn, and Zn were found in trace-amounts in all waste limestones, which was considered typical for such products.

In this study, steam gasification with sodium hydroxide was applied for recovery of tantalum sintered compact by destroying mold resin and stabilization of halogenated compounds in sodium hydroxide to prevent exhausting halogenated gas. Mold resin can be decomposed by steam gasification with NaOH to recover the sintered compact of tantalum. Furthermore, most halogen gas generated from decomposition of mold resin can be trapped in sodium hydroxide not to exhaust halogen gas.

Oxygen and carbon dioxide transmission rates (O2TR and CO2TR) of mango (<em>Mangifera indica</em>, L.) peel at different stages of maturity and ripeness which were stored under two temperature regimes were measured using gas diffusion chamber. Nitrogen gas was flushed inside the chamber to decrease the oxygen level.
