Arid Zones - an overview | ScienceDirect Topics

Drylands are classified as rangelands, croplands, or urban (Figure 5).Drylands tend to have low amounts of soil organic matter and low soil fertility. In spite of this, and the xeric nature of drylands, more than 44% of all cultivated land in the world is found within drylands (EMG, 2011).Most of the cropping systems are concentrated on the more mesic range of the gradient …

Effects of combination of tillage with olive mill ...

In arid regions, the low soil fertility and the need for water scarcity lead farmers to use olive mill wastewater (OMW) as an adopted management strategy that enhances soil quality. Indeed, more than 30 million m 3 of OMW are produced annually in Mediterranean basin (D'Annibale et al. 2004 ) by three phases olive oil extraction plant.

Most of these mills performed mainly service dehulling and milling for neighboring farmers. Small quantities of sorghum meal were sold from the mill or in nearby retail shops. By the late 1980s, only one medium-scale commercial sorghum mill had been established in the country.

The agricultural potential of selected C4 plants in arid ...

Due to the increasing amount of dry lands in the world, C 4 plants which are highly efficient in water use need to be investigated as potential crop species. This study examined the arid-land agricultural potential of several specific C 4 species: Amaranthus hypochondriacus, Amaranthus retroflexus, and Portulaca oleracea. Germination responses of each species to …

The Mills - Oregon History Project

The mill at Camp Watson shipped its lumber through Prineville and added facilities there in 1938 and 1940. In 1946, they built the first of several Hudspeth mills in Prineville. John M. Hudspeth became a major force in the lumber business of Oregon and the West during the middle decades of the century.

Tellurium biogeochemical transformation and cycling in a ...

Tellurium biogeochemistry has not been widely studied for three main reasons: (1) cycling of rare trace elements was not widely analysed until recently (Vriens et al., 2014, Liu et al., 2020a); (2) Te was a little used element in the 20th century (Goldfarb et al., 2017); and (3) the unusual chemical behaviour and low abundance of Te make it difficult to analyse (Schirmer et …

10 great films set in the desert | BFI

The list of westerns to have made great use of desert locations is as long and endless as a distant horizon: think of James Stewart being ambushed on desolate salt flats in Anthony Mann's The Man from Laramie (1955), or the arid vistas in John Ford's The Searchers (1956), which David Lean reportedly watched over and over in preparation for ...

C. Wright Mills' The Sociological Imagination and the ...

C. Wright Mills was one of the most important critics of Talcott Parsons who succeeded in establishing the image of Parsons as a conservative "grand theorist" out of touch with the real world and its real problems, as passed on in sociological textbooks. In this essay, it is argued that Mills' "translation of Parsons into English" is a one-sided interpretation based on …

Recovering Australia's arid‐zone ecosystems: learning from ...

The native arid-zone mammals that have generally benefitted from the biological control of rabbits, apart from mulgaras, appear to be either too large (kangaroos, wallabies, and wombats) or too small (rodents and smaller dasyurids) to fall within the critical weight range of animals most heavily preyed upon by cats and foxes.

Journal of Arid Land

Journal of Arid Land. 2022, 14 (1): 1-13. DOI: 10.1007/s40333-022-0001-4. As an important natural resource, forest land plays a key role in the maintenance of ecological security. However, variations of forest land in the agropastoral ecotone of northern China (AENC) have attracted little attention.
