In his sped up Reclamation of Alkaline Argillaceous Soils of Azerbaijan, Professor Mukhtar Abduyev describes the tackling of a usual challenge which had huge, immense implications for Azerbaijan's safeguard of foodstuff offer. the duty was once to discover extra effective equipment of reclaiming the saline soils that lined greater than 60% of the republic's lowlands - a few 2.5 million hectares have been proof against development. present tools of reclamation concerned substantial quantities of water for leaching and the development of intensive drainage platforms; those equipment may possibly soak up to ten years to develop into potent. Prof. Abduyev as a rule followed a pragmatic medical procedure, getting to know a variety of equipment of salt removing and their impression on soils and the plants to be grown in them. He was once additionally a hugely revered instructor and used to be without delay fascinated by box investigations, whilst delivering management and priceless hands-on adventure for graduate scholars and learn staff. Prof....

Cinquante Ans de Polynômes Fifty Years of Polynomials: Proceedings of a Conference held in honour of Alain Durand at the Institut Henri Poincaré Paris, France, May 26–27, 1988

Ahead of his premature demise in 1986, Alain Durand had undertaken a scientific and in-depth learn of the mathematics views of polynomials. 4 unpublished articles of his, shaped the center piece of realization at a colloquium in Paris in 1988 and are reproduced during this quantity including eleven different papers on heavily similar themes.

Howler Monkeys: Adaptive Radiation, Systematics, and Morphology

Howler monkeys (genus Alouatta) include 12 species of leaf-eating New international monkeys that variety from southern Mexico via northern Argentina. This genus is the main frequent of any New global primate and will be stumbled on to inhabit a number of woodland kinds from undisturbed rainforest to significantly anthropogenically-impacted wooded area fragments.

Sample text

To our thinking, this may be related to the salinity of the soils. By the content of absorbed sodium, the salinity of these soils is 15-20% of the total of absorbed base in the upper zones of the plains, and 30-40% and above in the soils of border strips, where suberous solonetzes are generally developed. A distinct feature of the soils of the diluvial plains is accumulation of maximum salt at a certain (generally, not great) depth depending on the gradient of the locality. 5%, whilst the figure for the border zone part of the slopes is 2-3%.

Leaching of soils without application of chemical reclamation agents: the usual leaching. II. Leaching of soils with application of gypsum: 1) Leaching with application of gypsum at 5 tonnes/ha, 2) Leaching with application of gypsum at 10 tonnes/ha, 3) Leaching with application of gypsum at 20 tonnes/ha, 4) Leaching with application of gypsum at 40 tonnes/ha. III. Leaching of soils with application of gypsum and manure: 5) Leaching with application of gypsum at 5 tonnes/ha and manure at 40 tonnes/ha, 6) Leaching with application of gypsum at 10 tonnes/ha and manure at 40 tonnes/ha, 7) Leaching with application of gypsum at 20 tonnes/ha and manure at 40 tonnes/ha.

The data for total alkalinity and CO3 ion content are analogous. CO3 that appeared in the first half-metre layer after the first leaching disappeared [in the second leaching], whilst the content of HCO3 was insignificantly reduced, but its content in the lower horizons increased substantially. All this was reflected in the differentiation of the individual salts. As is seen from Table 7, sodium carbonate was absent in the soils after the second leaching. It was leached out like any other water-soluble salt in the subsequent leaching.
