The article provides an overview of agrochemical studies carried out on irrigated light chestnut and brown semi-desert soils of the Saratov, Volgograd regions and the Republic of Kalmykia. It is noted that in stationary experiments carried out in these regions, the influence of long-term use of mineral fertilizers on the transformation of agrochemical properties and the productivity of crop rotations of various specializations was studied. In numerous short-term experiments, the optimal types, doses and timing of mineral fertilizers were determined for the cultivation of cereals (spring and winter wheat, corn and sorghum for grain), legumes (soybeans, chickpeas), forage crops (Sudan grass, sugar sorghum, alfalfa, cereal mixtures for estuaries), technical (camelina, mustard) and vegetable (tomatoes, onions) crops.

Abstract. The territory of the Republic of Tatarstan (RT) belongs to the region with the most developed agriculture in Russia and the Middle Volga region. However, the formation of a system of accurate farming in the Republic is just beginning. To ensure precision farming, it is necessary to precisely know cropland borders, as well as the agrochemical properties of soils (pH, humus content, potassium and phosphorus content). The present study was carried out based on aerial images analyses of the most intensively used part of the RT both with identification of soil indicators for each of the fields. The availability of information on the spatial location of various cultivated crops makes it possible to assess the role of soil characteristics in these crops.

The studies of peatlands have been conducted in Saby and Tyulyachi municipal districts of the Republic of Tatarstan for the possible use of them in the forest breeding and seed center for the cultivation of seedlings of forest trees on the technology of the Swedish company BCC AB. We conducted field studies of peat samples in these municipal districts of the Republic of Tatarstan in 2011 and 2012. During the field studies some peat samples were collected from two sites for the full agro-chemical analysis. These peat samples were taken near the village Minger of Saby district, near the village Bolshie Meteski of Tyulyachi district. An agrochemical analysis of samples were hold at the Analytical Research Center of Tatar Scientific Research Institute of Agriculture of Russian Agricultural Academy. To evaluate the results of data of agrochemical analysis of peat samples, taken near the villages Minger and Bolshieg Meteski, have been compared with the data of table 2 and 3. By comparing the studied samples, we concluded that the agrochemicals characteristics of peat corresponded to indicators of lowland peat according to the scale of L.fon Post. The studies have shown that the studied peat deposits in Saby and Tyulyachi municipal districts of the Republic of Tatarstan for its agrochemical properties belong to the lowland peat, which makes them unsuitable for use on the above-mentioned technology. Upland sphagnum peat bogs in this study area are not available, which are necessary for the cultivation of seedlings of forest trees according to the technology of the Swedish company AB BCC.

Using the example of two crop rotation fields located in the chernozem zone of the Republic of Tatarstan, the spatial variability of soils agrochemical properties was assessed in terms of the application of precision farming technologies when applying mineral fertilizers. It is shown that the use of mixed samples of polygons with an area of 5 ha as an elementary sampling site is sufficient detail for a geostatistical description of the spatial heterogeneity of the agrochemical properties of chernozem soils.

In South Africa the modern outlook towards time may be said to have started in 1948. Both the two major observatories, The Royal Observatory in Cape Town and the Union Observatory (now known as the Republic Observatory) in Johannesburg had, of course, been involved in the astronomical determination of time almost from their inception, and the Johannesburg Observatory has been responsible for the official time of South Africa since 1908. However the pendulum clocks then in use could not be relied on to provide an accuracy better than about 1/10 second, which was of the same order as that of the astronomical observations. It is doubtful if much use was made of even this limited accuracy outside the two observatories, and although there may – occasionally have been a demand for more accurate time, it was certainly not voiced.
