Geotechnical engineering, also known as geotechnics, is the application of scientific methods and engineering principles to the acquisition, interpretation, and use of knowledge of materials of the Earth's crust and earth materials for the solution of engineering problems and the design of engineering works. It is the applied science of predicting the behavior of the Earth, its various. The purpose of this study was to explore the effects of biochar application on soils in the main tobacco-producing areas in China. The study was conducted in four study regions in China, where the same three experimental treatments were set up in each area, including a control (CK), a treatment involving the application of chemical fertilizer (F), and a treatment involving the application of Author: Huanhuan Wang, Tianbao Ren, Yuqing Feng, Kouzhu Liu, Huilin Feng, Guoshun Liu, Hongzhi Shi.

Tropical soils cover about 30 million km 2 of the Earth's surface, and are loosely defined as those weathering profiles that are characteristic of the non-desert low latitudes.
Such soils are defined principally by climate and stage of genetic development with particular examples dependent upon parent material and topography. The term ‘tropical soils’ is not as geographically inclusive as might be inferred from the name.
From a pedological point of view, the term traditionally does not include all soils occurring in tropical environments, soils of low‐latitude deserts typically being excluded, as are some pedogenically young (poorly developed) soils.
The Handbook of Tropical Residual Soil Engineering is intended as a complete reference source and manual for every engineer working on or interested in soil and foundation engineering in tropical areas. Almost all aspects of tropical residual soils are treated, including a range of engineering applications.

The consumption and destruction of soils, i.e., the destruction of the surface soil or of the topsoil, is one of the biggest ecological problems of the world. The soil is the basis for food. Know Soil Know Life then takes readers through a traditional sequence of soil science topics, including soil chemistry, biology, and classification, before drawing a direct line between people and soils once again.

It discusses the purposes and the current state of soil classification, as well as the following unresolved issues: what definition of soils should be the basis for a universal soil. If tropical peats were defined as being those between the tropics of Cancer and the tropics of Capricorn, it would leave out large areas of organic soils with features of tropical character.

Soil mapping, classification, and pedologic modeling have been important drivers in the advancement of our understanding of soil from the earliest days of the scientific study of soils. Early soil maps were desirable for purposes of land valuation for taxation, agronomic planning (Brevik and Hartemink, ), and even in military operations Cited by: Agricultural ecology, or agroecology, deals in general with the structure and function of agroecosystems at different levels of resolution.
In this text/reference, the authors describe in terms of agroecology the tropical environments of sub-Saharan Africa, Southeast Asia, and Latin and Central America, focusing on production and management systems unique to each region.

Mangroves are a fascinating group of plants that occur on tropical and subtropical shorelines of all continents, where they are exposed to saltwater inundation, low oxygen levels around their roots, high light and temperature conditions, and periodic tropical storms.
Despite these harsh conditions, mangroves may form luxuriant forests which are of significant economic and environmental value 5/5(1). Plant Nutrient Management in Hawaii’s Soils Approaches for Tropical and Subtropical Agriculture James A.
