Biological Soil Disinfestation

The influence of crop rotation and wheather conditions on the <i>Fusarium</i> population in soil and on <i>Fusarium</i> wilt of flax was examined in the Institute of Native Natural Fibres in 1968-1975. The experiments were carried out in various regions of flax planting in Poland during 8 years. Crop rotation had a significant influence on the process of biological soil disinfestation. <i>Fusarium</i> population in soil increased after planting flax, wheat, barley and sugar-beet, and decreased or did not change after rape, hemp, potato and leguminous plants. The crop rotation significantly influenced the composition of the <i>Fusarium</i> population as far as species are concerned. The highest wilt infection of flax was found in plantings after flax, sugarbeet and wheat and the weakest in plantings after rape. A six-year crop rotation was sufficient to eliminate the wilt pathogen from infested soil. But on flax-sick soil the process of biological disinfestation proceeded more slowly and a seven-year interval between flax crops was too short.

AbstractSoil O2 dynamics have significant influences on greenhouse gas emissions during soil management practice. In this study, we deployed O2-specific planar optodes to visualize spatiotemporal distribution of O2 in soils treated with biological soil disinfestation (BSD). This study aimed to reveal the role of anoxia development on emissions of N2O and CH4 from soil amended with crop residues during BSD period. The incorporation of crop residues includes wheat straw only, wheat straw with biochar and early straw incorporation. The anoxia in soil developed very fast within 3 days, while the O2 in headspace decreased much slower and it became anaerobic after 5 days, which was significantly affected by straw and biochar additions. The N2O emissions were positively correlated with soil hypoxic fraction. The CH4 emissions were not significant until the anoxia dominated in both soil and headspace. The co-application of biochar with straw delayed the anoxia development and extended the hypoxic area in soil, resulting in lower emissions of N2O and CH4. Those results highlight that the soil O2 dynamic was the key variable triggering the N2O and CH4 productions. Therefore, detailed information of soil O2 availability could be highly beneficial for optimizing the strategies of organic amendments incorporation in the BSD technique.

За результатами проведеного моніторингу забур’яненості посівів пшениці озимої, цукрових буряків і ячменю з підсівом багаторічних трав у ланці зернобурякової сівозміни у виробничих умовах встановлено видовий і кількісний склад бур’янів у посівах вищевказаних культур. Все це дає можливість спланувати і застосувати ефективні способи й методи боротьби із сегетальною рослинністю. В результаті проведених досліджень також встановлено, що на видовий склад поширених у посівах сільськогосподарських культур бур’янів має суттєвий вплив поєднання таких чинників, як спосіб основного обробітку ґрунту, попередник і передпопередник, система удобрення та особливості погодних умов веґетаційного періоду, а також біологічні властивості культури, що вирощується. Based on the results of the monitoring of the weediness of winter wheat, sugar beet and barley crops with the sowing of perennial grasses in the link of grain-beet crop rotation, the species and quantity composition of the weeds in the crops of the above-mentioned crops is determined under production conditions. All this makes it possible to plan and apply effective ways and methods of combating segetal vegetation. As a result of the conducted studies it was established that the combination of such factors as the method of basic tillage, the precursor and predecessor, the fertilizer system and the peculiarities of the weather conditions of the growing season, and the biological properties of the cultivated crop, have a significant influence on the species composition of weeds that are widespread in crops.

It is indicated on the role of crop rotation in increasing the productive potential of arable land. The output of products by feed and grain units from 1 ha of arable land in crop rotation with different ratios of grains and technical crops on the basis of the achieved level of yield of field crops in the conditions of a particular agrarian enterprise was established. For the conditions of Kitsman-Kelmentsy land evaluation area of Chernivtsi region, the effect of maize (corn, 1 or 2 fields) and sugar beet (1 or 2 fields) on the productivity of 7 fields rotation of cereals and row crops was studied. Humus balance is calculated and the main ways of improving humus conditions in rotation of cereals and row crops are given. The schemes of crop rotation have been established, providing the highest degree of realization of productive potential of arable land.

The purpose of this study is to analyze the role of institutional leadership, tax planning and foreign board of commissioners on firm value. The population in this study were 615 companies listed on the Indonesia Stock Exchange in 2015-2017. The sample was chosen using purposive sampling to get a total sample of 325 companies with a total of 975 observations of company data. The results of this study indicate that institutional leadership and tax planning have no role in increasing company value. While the foreign board of commissioners showed a significant influence on the value of the company. This proves that there is a need for diversity in the structure of the board that can trigger an increase in the value of the company. In addition, the presence of a foreign board is needed for the progress of the companyKeywords: Investment decisions; funding decisions; dividend policy; company value
