The proper management of agricultural crop residues could produce benefits in a warmer, more drought-prone world. Field experiments were conducted in sugarcane production areas in the Southern Brazil to assess the influence of crop residues on the soil surface in short-term CO2 emissions. The study was carried out over a period of 50 days after establishing 6 plots with and without crop residues applied to the soil surface. The effects of sugarcane residues on CO2 emissions were immediate; the emissions from residue-covered plots with equivalent densities of 3 (D50) and 6 (D100) t ha-1 (dry mass) were less than those from non-covered plots (D0). Additionally, the covered fields had lower soil temperatures and higher soil moisture for most of the studied days, especially during the periods of drought. Total emissions were as high as 553.62 ± 47.20 g CO2 m-2, and as low as 384.69 ± 31.69 g CO2 m-2 in non-covered (D0) and covered plot with an equivalent density of 3 t ha-1 (D50), respectively. Our results indicate a significant reduction in CO2 emissions, indicating conservation of soil carbon over the short-term period following the application of sugarcane residues to the soil surface.

ABSTRACT Soil structure conditions the interaction between the physical-hydraulic, chemical, and biological attributes and determines the potential of soil productivity. Therefore, the objective of this study was to evaluate the structure of soils of areas subjected to soybean production and the impacts of soil structure on crop yield. In total, 28 soybean production areas were selected in the State of Mato Grosso, Brazil, and analyzed for particle size, soil organic carbon and aggregates. Data of soil attributes were subjected to descriptive analysis, Pearson’s correlation and Kruskal-Wallis test at p ≤ 0.05. In general, considering the non-irrigated soybean production areas, it was found that soils with mean sand content between 100.00 and 800.10 g kg-1 and clay content between 120.00 and 627.80 g kg-1 showed average soybean yield of 3,536.36 kg ha-1. Soils that had aggregates with mean weight diameter and mean geometric diameter above 1.50 mm showed soybean yield equal to or greater than 3,370.67 kg ha-1. Soils of similar textural groups can define different levels of soybean yield, depending on characteristics such as the type of management adopted and production technology applied in the soybean production area.

The light industry is an important inter-sectoral segment and a chain of individual production areas. The purpose of the article is to carry out a comparative assessment of the cross-sectoral linkages of light industry of Ukraine with some EU countries and to prepare relevant analytical conclusions. The research revealed that the largest consumers of light industry products in 2013-2017 in Ukraine were the industries that belonged to this type of industrial activity (textile, clothing, leather and other materials), as well as the trade, furniture industry, public administration, and defense. The key problem for the functioning of the Ukrainian light industry is its high import dependence. In particular, the share of imports in intermediate consumption of light industry of Ukraine in 2017 was almost 60%. The share of imports in the expenditures of the Ukrainian light industry was almost 49%. The production activities of light industry in Ukraine use products of many ECs, but the main suppliers of raw materials and components are: textile production, production of clothing, leather, and other materials; production of chemicals and chemical products; wholesale and retail trade; supply of electricity, gas, steam, and air conditioning. In 2017, these four sectors totaled 70.74%. The following types of industrial activity in Ukraine have a significant potential for increasing output: production of rubber and plastic products; production of motor vehicles, trailers and semi-trailers; production of other vehicles; public administration and defense; compulsory social security; health care and social assistance. The further development and improvement of the technological level of Ukrainian light industry products requires greater integration of the latter with the trade sector. However, the trade sector in Ukraine requires a thorough “unshadowing”, i.e. legalization of all operations.
