The results of many years of original research based on soil-ecological monitoring showed the development of degradation processes of previously drained peat soils of the Ryazan Meshchera. Structural amelioration (sanding) of peat soils had some positive effect. The aim of the research was to study the properties of the dried peat soil at reclamation site Tinki-II in the settlement of Polkovo, Ryazan District of Ryazan Region, as a result of sanding. The most common type of German mixed-layer sanding was used in investigations. The methodology was based on the principle of comparing the state of dried peat soil before and after sanding. The content of the less than 0.01 mm fractions was 4.3 %, the rest consisted of particles from 0.25 to 0.05 mm; the pH of the salt extract was 5.7. Mineral fertilizers were applied in the experiment in small quantities: ammonium nitrate -180 g, superphosphate -185 g and potassium sulfate -260 g. The water supply was atmospheric-ground. Variant 2 was more effectivesanding with a dose of 1200 t/ha for sluicing and maintaining GWL = 90 cm, as evidenced by improved water-physical properties of the soil: the total porosity increased by 5 %; the total water capacity decreased from 270 to 70%, that was almost 4 times.

Developments in selection and emergence of new varieties and hybrids of oilseeds, which have a better ratio of the fatty acid composition of the oil, make is possible to promote such types of crops as camelina, colza, rapeseed and others. The paper presents an analysis of the quality of new and promising varieties and hybrids of oilseeds, which, according to their morphological and biological characteristics, are successfully cultivated in conditions of the Non-Chernozem Zone of Russia. It is confirmed that oil quality is due to genetic characteristics of the variety and hybrid. The quality of seeds of spring rapeseed Ratnik, Cyclus KL, Curry KL, Salsa KL, Cultus KL, Ozorno, Cebra and other studied varieties and hybrids of the 00 type are close to olive oil in their fatty acid composition and are not inferior to the quality of sunflower oil. There is a high content of important C18:1 oleic acid in oil of rapeseed (59-65 %), and a low content of the total of C16:0 palmitic + C18:0 stearic (5.5-6.0 %). The data on the high quality of camelina oil are presented, which allows the use of varieties Yubilyar and Veles for production of vegetable oil with a high content of unsaturated acids for food purposes. The work discusses the current restrictive norms for the supply of oilseeds and determining the standard weight for oil refining enterprises.

The article proposes the results of investigations on agroecological assessment of oil flax varieties depending on the sowing time in the southern part of the Nonchernozem belt of Russia. The experiments took place at the agrotechnological experimental station of Ryazan State Agrotechnological University Named after P.A. Kostychev on gray forest soil typical of the region. It should be noted that the introduction of new varieties into the zone requires a more detailed study of the technology of their cultivation, including the determination of the optimal seeding rate and sowing date for specific weather conditions. The objects of investigations were domestic varieties of flax: Istok, VNIIMK 620, Sunlin and LM 98. Sowing was carried out in two terms - the third decade of April and the first decade of May. According to the results of experiments, it can be concluded that the yield was formed due to the density of planting, largely due to better survival in the second term of sowing. Despite significantly lower yield parameters of the second crop, such as the number of bolls per plant, the mass of 1,000 seeds, the number of seeds per boll, the yield of Sunlin and LM-98 varieties was higher than in the first term of sowing. On average, the maximum productivity was shown by Istok variety when the first sowing period (21.2 dt/ha) and Sunlin variety when the second period of sowing (20.6 dt/ha). During the years of studying varieties, flax oil content was 36.3-46.3 %. There was a decrease in this parameter in all experimental varieties by 1-3.5 % in the second period of sowing.
