Soil fertility

Abstract
The article presents the results of three years of research (2013-2015) for fine alfalfa irrigation technology in Apsheron. In this respect, studies have been conducted in the three messages: I variant - alfalfa irrigation with irrigation (control); II variant - irrigation of alfalfa particulate moisture combined with irrigation; III variant - irrigation of alfalfa particulate moisture. The study revealed that the application of irrigation melkodispersnaja humidification combined with improved irrigation phytoclimate alfalfa plants in hot, sunny days is reduced to 100°C air temperature and the relative humidity is increased by 30-40 %. Ultimately, eliminating depression photosynthesis and thereby expended irrigation compared to the control one (I variant), in the II- th version 1,25, and the variant- III at 1,85 times less irrigation water. Accordingly, when variations of experiment II variant yield increases by 1.4 times, while conversely embodiment III decreases 0,93 times, i.e. 7,3%.

Abstract
The article presents data on the influence of physiologically active preparations -adaptogens C-1-1, PA-2-1 on maize yields in saline soils Otrar district of South Kazakhstan region. Showed a positive effect of the preparations - adaptogens on growth, development and yield of maize. The use of preparations - adaptogens provide reliable corn yield increase over 36 c/ha.

The ecological structure of nematodes complex based on their belonging to the certain trophic groups by the nature feeds have studied. The quantitative and quality analysis of nematodes trophic groups in chernozems at No-Till and minimum treatments presented in the article.

Soil ecology

Abstract
As a result of research have revealed that the main source of pollution of a skilled site is the zinc plant. The area of distribution of emissions of plant in circles makes 2 km, with special influence on a wind rose in east direction from plant towards the city. In the territory in a radius of 2 km strong influence of emissions of plant on a soil and vegetable cover which is subjected to strong erosive processes is revealed. Analyses of water physical properties have shown that humidity of soils increases with depth (20 - 30 cm). Increase in volume weight in soils near zinc plant is explained by significant influence of TM. They destroy composition of organic acids that respectively influences an aggregate state, there is an increase in thin fractions, from PPK the absorbed calcium is forced out, units collapse and there is a consolidation, especially top horizons. The low maintenance of a humus is explained by the fact that on a surface of chernozems practically all vegetable communities have disappeared. Security of soils with absorbing forms of nitrogen and mobile phosphorus is low. Content of mobile potassium is high.

Abstract
It was found that mineral fertilizers are major factors which significantly improves plant growth and development of highly productive corn hybrids Kazakh-Serbian selection - "SKIF-619" and "Sunkar - 779" under conditions of irrigation. The high responsiveness of these hybrids on fertilizers additional allows to get up to 219-436 centners of green mass per hectare. Hybrid "Sunkar - 779" has a higher responsiveness to fertilizers than hybrids "Skif-619." Adding each kg of active substance fertilizers (NPK) provided on fertilized variants, obtaining additional 150 - 90 kg / ha of green mass, respectively.

Abstract
The characteristic of micromorphological properties of two desert soils - brown and gray-brown have given. It has shown that brown desert soils have fragile structure of aggregates, the compact microtexture and high content of primary minerals and fragments of dense rocks. Stages of transformation of the plant residues and pronounced biological activity in a middle part of a profile have noted that it have explained by more favorable habitat of conditions: temperature and moist regime. The special attention have paid to accumulation of carbonates, its various forms and the sizes. Micromorphological researches of gray-brown soils have shown that in the top part of the horizon A existence of a bubbly (vesicular) pores of the different sizes characteristic of desert pedogenesis, the compact microtexture of a middle part of a profile connected with accumulation of fine clay material in the form of coatings (kutana) and infilling in voids and also iron compounds.

Review

Abstract
Kazakhstan has significant scientists, among which are especially allocated pioneers - soil scientists. The names of people form the real story. The memory of the prominent soil scientist is fixed in their works, embodied in place-names. Intellectual history - is to popularize of science and disclosure of hidden, unknown to a wider audience of scientists' life aspects, which poses a lot. The old history of science, intellectual history, the history of ideas and place-names in honor of soil scientists will help to understand the origins and importance of soil science, to overestimate the old. The aim of the article is to awaken respect for the pioneers of science through interest in the past.
