Soil science is the study of soil as a natural resource on the surface of the Earth including soil formation, classification and mapping; physical, chemical, biological, and fertility properties of soils; and these properties in relation to the use and management of soils.

Akadama is a naturally occurring, granular clay-like mineral used as soil for bonsai trees and other container-grown plants. It is surface-mined, immediately sifted and bagged, and supplied in various grades: the deeper-mined grade being somewhat harder and more useful in horticulture than the more shallow-mined grades. Akadama may also act as one component of growing medium when combined with other elements such as sand, composted bark, peat, or crushed lava. Akadama’s colour darkens when moist which can help the grower determine when to water a tree.

Barren vegetation describes an area of land where plant growth may be sparse, stunted, and/or contain limited biodiversity. Environmental conditions such as toxic or infertile soil, high winds, coastal salt-spray and climatic conditions are often key factors in poor plant growth and development. Barren vegetation can be categorized depending on the climate, geology and the geographic location of a specific area. Pine Barrens, coastal barrens and serpentine barrens are some of the more distinct ecoregions for barren vegetation and are the most commonly researched by scientists. Often referred to as "heathlands", barrens can be excellent environments for unique biological diversity and taxonomic compositions.

In soil science, agriculture and gardening, hardpan or ouklip is a dense layer of soil, usually found below the uppermost topsoil layer. There are different types of hardpan, all sharing the general characteristic of being a distinct soil layer that is largely impervious to water. Some hardpans are formed by deposits in the soil that fuse and bind the soil particles. These deposits can range from dissolved silica to matrices formed from iron oxides and calcium carbonate. Others are man-made, such as hardpan formed by compaction from repeated plowing, particularly with moldboard plows, or by heavy traffic or pollution.

An acrisol is a type of soil as classified by the Food and Agriculture Organization. It is clay-rich, and is associated with humid, tropical climates, such as those found in Brazil, and often supports forested areas. It is one of the 30 major soil groups of the World Reference Base for Soil Resources. Acrisols correspond to the aquult, humults, udults and ustults sub-orders of ultisols in the USDA soil taxonomy and also to oxisols with a candic horizons and some alfisols. The acrisols low fertility and toxic amounts of aluminium pose limitations to its agricultural use, favouring in many places its use for silviculture, low intensity pasture and protected areas. Crops that can be successfully cultivated, if climate allows, include tea, rubber tree, oil palm, coffee and sugar cane.

The Professional Soil Classifiers Association of Alabama adopted a resolution at its 1996 annual meeting recommending the Bama Soil Series as the state soil. The association is composed of a group of soil classifiers representing the Alabama Cooperative Extension System, the Alabama Agricultural Experiment Station, the USDA-Natural Resources Conservation Service, the Alabama A&M University, private soil consultants, the Board of Registration for Professional Soil Classifiers, and the Alabama Department of Public Health. The Alabama Soil and Water Conservation Committee and the Alabama Association of Conservation Districts also joined in recommending the Bama Soil Series as the official State Soil. The Bama series was designated the official state soil by the Alabama Legislature on April 22, 1997.

Acid sulfate soils are naturally occurring soils, sediments or organic substrates (e.g. peat) that are formed under waterlogged conditions. These soils contain iron sulfide minerals (predominantly as the mineral pyrite) or their oxidation products. In an undisturbed state below the water table, acid sulfate soils are benign. However, if the soils are drained, excavated or exposed to air by a lowering of the water table, the sulfides react with oxygen to form sulfuric acid.

Many people say in their CV that they are good at working cooperatively or are team players, but few say what this actually means. Think about examples from your past that demonstrate your ability to build bridges, form networks or simply get on with people. This needn’t be from your professional life. You could cite any examples from clubs or organisations to which you belong.

Answering this question well is especially important for people who want to be team leaders or to manage a department.

If you are highly qualified for the job you are applying for, then you should point this out, but don’t forget that other people being interviewed may match or exceed your suitability. In such cases, focus on what else you can bring to the job, perhaps with your soft skill set, like being able to integrate well with existing members of the team, for instance.

Don’t give up on an interview if you´re not fully qualified for the job. Appeal to the interviewer’s desire to hire someone with drive. If you are not the finished article, then point out how keen you are to learn and be mentored. Accentuate the positive aspects of what you can do now and how quickly you will be able to progress with what you don’t know if hired.

In environments containing permafrost, the active layer is the top layer of soil that thaws during the summer and freezes again during the autumn. In all climates, whether they contain permafrost or not, the temperature in the lower levels of the soil will remain more stable than that at the surface, where the influence of the ambient temperature is greatest. This means that, over many years, the influence of cooling in winter and heating in summer will decrease as depth increases.
