Los impactos ambientales de los metales pesados en los suelos están relacionados con su carácter tóxico cuando se acumulan o interactúan con algunas propiedades específicas, se movilizan a través del perfil a la cadena trófica mediante los cuerpos de agua o los cultivos y pueden llegar a afectar la salud humana. En países desarrollados el establecimiento de valores de referencia de estos metales ha permitido el mejoramiento de la planeación y la gestión ambiental del recurso suelo, y se ha convertido en un instrumento de control para las entidades ambientales que ha permitido evaluar el impacto en diferentes actividades agrícolas. En este artículo se analizan diversos conceptos relacionados con los niveles de metales pesados en suelos agrícolas y la incidencia de las características edafológicas en su concentración. Se revisan, igualmente, algunas metodologías para derivar valores de referencia específicos aplicables a suelos agrícolas colombianos, y se plantean algunas perspectivas orientadas a la protección y recuperación de suelos en el país. En Colombia en la actualidad no se cuenta con criterios y estándares de calidad para medir la contaminación por metales pesados en suelos agrícolas; por esto se hace necesario gestionar el apoyo de entidades gubernamentales con el fin de iniciar y desarrollar investigaciones en diferentes sectores agrícolas primarios, contribuyendo de esta forma a garantizar una producción más limpia y la sostenibilidad ambiental del recurso suelo. | From an environmental perspective, the importance of heavy metals in soils is related to their toxicity either due to accumulation or to any interaction among them and some of their specific properties. In each case, heavy metals can move through the soil profile and transfer into the trofic chain by using through water bodies or crops affecting de human health. In developed countries, the establishment of baseline values has permitted improvements in the environmental management plans of soils. Baseline values are transforming in a control tool for environmental agencies to test the impact of heavy metals in a variety of agricultural activities. This article analyses different concepts related to heavy metals levels in agricultural soils and the incidents of the soil characteristics on their concentration, at the same time some methodologies to obtain specific baseline values from identification of the natural concentration are reviewed. Also included are some prospects for Colombia related to soil protection and remediation. Currently, in Colombia there are no studies related to obtain baseline values of heavy metals in agricultural soils. For this reason it is necessary to get support from government agencies such as the Ministry of Environment, housing and territorial development and Ministry of agriculture, in order to start and develop research in some primary agricultural sectors to guarantee the production and the environmental sustainability of soils.

This study targeted to elucidate the effect of seed aging on germination and emergence rates with and shoot characteristics in wheat cultivars. For this purpose, different bread wheat cultivars stored for 7 years and non-stored were compared for coleoptile length, root mass, shoot mass, root length as well as germination and seedling emergence rates. Here, the evidence suggested that seed storage over a prolonged period affected root and Shoot growth, coleoptile length, seed germination, and seedling emergence rates adversely. By linking germination and emergence rates, the data presented here indicated that a reduction in emergence rate in long-term storage was higher than that in the germination rate. It was also found that there were significant variations among the wheat cultivars about investigated traits during long-term storage. However, the emergence rates of Kate A1 and Flamura 85 were not affected substantially by long-term storage. The study suggested future studies to focus on clarification of the process controlling natural seed aging as such knowledge allows clue the eventual consequences of long-term storage.

The paper presents results of survey research conducted in Łuck (Ukraine) and Biała Podlaska (Poland) in 2014. A total of 100 people, half of them Polish and the other half Ukrainian, were interviewed in the study. They were asked twelve questions, including ten open-ended questions and two questions which had 2-3 answers to choose from. The survey was anonymous and was carried out in five age groups. Analysis of the answers demonstrated that most respondents grew their own potatoes. The majority of Polish respondents said they consumed potatoes once or twice per week, Ukrainians eating them three or four times per week. In both countries, the preferred consumption form was boiled potatoes. Tubers for consumption were produced by the respondents or were purchased, mainly at the market. The majority of Poles wanted to know the country of origin of the potatoes they wanted to buy. Also, they were interested in the label attached to the package of the potatoes. Ukrainians predominantly made their decisions based on the price, the labelling being the least important. Respondents from both countries paid the greatest attention to potato flavour; they expected potatoes to be characterised by good cooking quality and appealing external appearance. They were by far less interested in an informative label and affordable price. / Synopsis. W pracy przedstawiono wyniki badań ankietowych, przeprowadzonych metodą wywiadu bezpośredniego w 2014 roku na terenie Ukrainy, w mieście Łuck i Polski, w mieście Biała Podlaska. W badaniach uczestniczyło 100 osób pochodzących po połowie z Ukrainy i Polski. Kwestionariusz ankietowy zawierał dwanaście pytań, w tym dziesięć pytań zamkniętych i dwa, w których trzeba było wybrać 2-3 warianty odpowiedzi. Badania przeprowadzono anonimowo, uwzględniając pięć przedziałów wiekowych respondentów. Analiza udzielonych odpowiedzi wskazała, że większość ankietowanych uprawiało ziemniak w swoim gospodarstwie. W Polsce największa liczba respondentów stwierdziła, że spożywają bulwy ziemniaka 1-2 razy w tygodniu, mieszkańcy Ukrainy preferowali spożywanie 3-4 razy w tygodniu, a preferowaną formą w obu krajach były ziemniaki gotowane z wody. Bulwy do celów konsumpcyjnych pochodziły z własnej produkcji oraz kupowane były głównie na bazarze. Większość ankietowanych Polaków interesowała się krajem pochodzenia kupowanych ziemniaków oraz etykietą na opakowaniu. Na decyzje zakupowe mieszkańców Ukrainy wpływała głównie cena, a opakowanie miało najmniejsze znaczenie. Ankietowani pochodzący z obu krajów najbardziej doceniali w ziemniaku dobre walory smakowe, ponadto oczekiwali bulw o dobrej jakości kulinarnej i o dobrym wyglądzie zewnętrznym. Zdecydowanie mniejsze wymagania ankietowanych dotyczyły „bogatej” w informacje etykiety i przystępnej ceny.

Apple cultivation has been done in very large areas around the world. According to FAO, approximately 87.2 million tons of apples were produced in the world in 2019. Turkey has covered 3.6 million tons of this production and ranked third in the world. In this study, the two major apple production areas for Turkey, Isparta and Karaman annual operating results of the province apples' farms, were evaluated. Data acquired by interviewing from 132 farms selected with the stratified random sampling method constituted the study's primary material. Classical economic analysis approaches were used in determining the annual operating results of the farms. The farms' financial and economic profitability rates were 8.82% and 7.78% in Isparta province, respectively, while 7.25% and 6.15% in Karaman province. The research results showed that apple farms did not have rational capital distribution, their agricultural incomes were low, and their income varied by province.

The study presents the importance of logistics in deepening globalization, especially in the use of maritime transport. This transport industry is the most widely used in the international flow of goods. It was found that world-wide transport from the mid-1990s increased almost by half, which was due to the most increased shipment of general cargo (2.6 times) and container loads (2 times). If the current trends in the pace of globalization processes are maintained in the future, rapidly developing Asian countries will be the deciding factor, while the role of developed European countries and the United States will decline. / Synopsis. W opracowaniu przedstawiono znaczenie logistyki w pogłębianiu globalizacji, zwłaszcza w zakresie wykorzystania transportu morskiego. Ten dział transportu jest bowiem najszerzej wykorzystywany w międzynarodowych przepływach towarów. Stwierdzono, że przewozy w skali świata od połowy lat 90. wzrosły prawie o połowę, do czego przyczyniło się najbardziej zwiększone przemieszczanie ładunków drobnicowych (2,6-krotnie) i kontenerowych (2 razy). Jeśli zostaną utrzymane dotychczasowe trendy o tempie procesów globalizacji w przyszłości będą decydować szybko rozwijające się państwa azjatyckie, zaś zmaleje rola rozwiniętych państw europejskich i Stanów Zjednoczonych.
