The issues of soil fertility reproduction are usually considered as a system of specific measures. This article presents a slightly different approach, the essence of which is to substantiate the methodology for constructing the concept of fertility reproduction, to formulate goals, tasks, to determine the method of forming indicative indicators and to assess effectiveness. The data for the Rostov region on the dynamics of nutrients balance in the soil and the assessment of the effectiveness of changing the structure of sown areas are presented.

Рассмотрены биологические особенности баклажана с белой окраской плодов, их пищевые и лечебные свойства. Сорта баклажана с белой окраской плодов отличаются высокими вкусовыми качествами и гипоаллергенностью. Они могут использоваться в детском и диетическом питании. Их используют в домашней кулинарии, в лечебном и профилактическом питании. Исследования проводили в центральной части Ростовской области. Климат зоны континентальный, засушливый. Изучение велось в необогреваемых весенних пленочных теплицах и открытом грунте. В исследованиях руководствовались общепринятыми методиками. Материалом для исследований служили образцы мировой коллекции с белой окраской плодов, современные сорта и гибриды отечественной и зарубежной селекции, собственный селекционный материал. Получен ряд образцом с комплексом хозяйственно ценных признаков и представлена характеристика перспективных сортов с белой окраской плодов Умка и Альбион. Новые сорта баклажана с белой окраской плода отличаются высокими вкусовыми и питательными качествами и обладают устойчивостью к болезням увядания. Приведены технологические особенности выращивания белоплодных форм баклажана в условиях юга России, включающие необходимость использовать качественную рассаду. Сортообразцы с белой окраской плодов наиболее требовательны к теплу, почвенному плодородию и нуждаются в тщательном систематическом контроле вредителей и возбудителей болезни. В период выращивания следует применять биопрепараты для защиты от вредных объектов. Рекомендуется заменить обрезку растений на прищипку с подвязкой побегов к шпалере.Biological features of an eggplant with white coloring of fruits, their food and medicinal properties are considered. Eggplant grades with white coloring of fruits differ in high tastes and hypoallergenicity. They can be used in baby and dietary food. They are used in house cookery, in clinical and preventive foods. Researches were conducted in the central part of the Rostov region. Climate of a zone continental, droughty. Studying was conducted in not warmed spring film greenhouses and the open ground. In researches were guided by the standard techniques. As material for researches served samples of a world collection with white coloring of fruits, modern grades and hybrids of domestic and foreign selection, own selection material. A row by a sample with a complex utility of valuable signs is received and the characteristic of perspective grades with white coloring of fruits of Umkа and Albion is submitted. New grades of an eggplant with white coloring of a fruit differ in high flavoring and nutritious qualities and have resistance to withering diseases. The technological features of cultivation of white-fruit forms of an eggplant in the conditions of the South of Russia including need to use qualitative seedling are given. Varieties with white coloring of fruits we are most exacting to heat, soil fertility and need careful systematic control of wreckers and infecting agents. During cultivation it is necessary to apply biological products to protection against harmful objects. It is recommended to replace cutting of plants with a nipping with a garter of escapes to a lane.

The tasks of agrotechnical and land-reclamation techniques in creating favorable conditions for the agricultural crops growth are determined. Maintaining high soil fertility and good land-reclamation. Soil fertility model with optimal indicators providing a combined expanded reproduction of soil fertility is proposed. Main indicators of potential soil fertility are considered. Indicators and properties of soils are captured, the relationship between plant productivity and soils quality is made. The adverse soil properties of the North Caucasus that include alkalescency and alkalinity are determined. Complex of agrotechnical and land-reclamation techniques for improving adverse soils is proposed.

Soil fertility determines a plant's development process that guarantees food sufficiency and the security of lives and properties through bumper harvests. The fertility of soil varies according to regions, thereby determining the type of crops to be planted. However, there is no repository or any source of information about the fertility of the soil in any region in Nigeria especially the Northwest of the country. The only available information is soil samples with their attributes which gives little or no information to the average farmer. This has affected crop yield in all the regions, more particularly the Northwest region, thus resulting in lower food production.  Therefore, this study is aimed at classifying soil data based on their fertility in the Northwest region of Nigeria using R programming. Data were obtained from the department of soil science from Ahmadu Bello University, Zaria. The data contain 400 soil samples containing 13 attributes. The relationship between soil attributes was observed based on the data. K-means clustering algorithm was employed in analyzing soil fertility clusters. Four clusters were identified with cluster 1 having the highest fertility, followed by 2 and the fertility decreases with an increasing number of clusters. The identification of the most fertile clusters will guide farmers on where best to concentrate on when planting their crops in order to improve productivity and crop yield.

The soil fertility aspect is characterized by the good biological properties of the soil. One important element of the soil biological properties is the bacterial population present in it. This research was conducted in the laboratory of Microbiology University of Malikussaleh in the May until June 2016. This study aims to determine the number of bacterial populations in soil organic and inorganic so that can be used as an indicator to know the level of soil fertility. Data analysis was done by T-Test that is by comparing the mean of observation parameter to each soil sample. The sampling method used is a composite method, which combines 9 of soil samples taken from 9 sample points on the same plot diagonally both on organic soil and inorganic soil. The results showed the highest bacterial population was found in total organic soil cfu 180500000 and total inorganic soil cfu 62.500.000
