| Se-supplemented fertilization is the main factor affecting the selenium (Se) contents of cereals in Finland. Soil and climatic conditions determine the activity of selenate added to soils and bioavailability to plants. In the present study the Se contents and its variation in Finnish oats, the differences between oat cultivars and cultivation techniques were examined. The selenium (Se) contents of oats (Avena sativa L.) in Finland were examined during 1997-1999 in 3 types of trial: official variety, organic cultivation variety and organic vs. conventional cultivation trials. Farm samples were also examined. The mean Se contents of oats in official variety trials were 0.110, 0.120 and 0.160 mg kg-1 dry weight (dw) range 0.016-0.460 mg kg-1dw in 1997-1999,... |

| Lignans are phytoestrogens found ubiquitously throughout the plant kingdom and thus are also present in our diet. After ingestion lignans go through various transformations and in the end they form mammalian lignans by microbial conversion. The amount of these mammalian lignans in human body is linked to the reduced risk of various hormonal dependent cancers such as breast cancer. Flaxseed (Linum usitatissimum L.) is one of the richest sources of lignans used in the human diet. Unfortunately, flaxseed also picks up cadmium very efficiently from the soil, which has to be kept in mind when choosing what regions to cultivate it in. SDG-lignan, cadmium and lead contents were studied in linseed, flax and oil hemp variety samples. Oil hemp samples were... |

| ß-Glucan is a beneficial chemical compound in the diet of humans by decreasing the levels of serum cholesterol and blood glucose. The ß-glucan contents of oat groats were studied in official variety trials (1997-1999), nitrogen fertilization trials (1997-1999) and organic variety trials (1997-1998) in Finland. Eight cultivars were studied in the organic variety trials. Two of them, cultivars Puhti and Veli, were cultivated also with a conventional method at the same fields. The years 1997 and 1999 were very warm and dry and 1998 very cool and rainy. The effects of year and cultivar on ß-glucan content were significant in all three trial series. The Kolbu oat cultivar had a significantly lower ß- glucan content than other cultivars in all trials. N... |

| The main aim of this investigation was to study trace element contents in the Finnish arable land on crop and dairy farms. The crop farms were located on clay soils and the dairy farms on finesand soils. The agua regia extractable trace elements in the top- and subsoil of the clay soils at the crop farms were two to three times those of the finesand soils at the dairy farms. Most of the elements were significantly correlated with the clay content. Quantitatively more Cd, Pb and Hg enriched in the clay soils on the crop farms in southwestern Finland than in the finesand soils on the dairy farms in Ostrobothnia. However, dairy farming seemed to enrich the topsoil with more Cr, Cu, Se, V and Zn than crop farming, on average. |

| Natural toxins, such as mycotoxins, have emerged as a significant factor affecting the safety image of cereal grains as a raw material for the food and feed industry. The aim of the present study was to investigate the contents of trichothecenes in representative samples of oats during official variety, nitrogen fertilization and organic farming trials in Finland, 1997–1999. Further objectives were to promote industry and commerce by selection of high-quality oat varieties for various applications. The official variety trials conducted at 8–10 locations were managed following standard protocol. There were 2 types of agronomy trial, the first included comparison of oat cultivars grown in conventional and organic farming systems at 6 locations, and the... |

| This study was part of a three-year (2004-2007) project entitled "Assessment and reduction of heavy metal inputs into Finnish agro-ecosystems" that was funded by the Ministry of Agriculture and Forestry in Finland. The main aim of this study was to estimate field balances of trace elements at the farm level on typical crop and dairy farms in Finland in 2004. Field balances estimated at the farm level showed that the balances of the harmful heavy metals, Cd and Hg, were often slightly positive leading in accumulation of these metals into the soil on the crop and dairy farms. Selenium indicated a highly positive balance resulting in enrichment of this element in the soil in both farming systems. Also, the Cu and Zn balances were positive on the dairy... |

| In Finland compound fertilizers have been supplemented with selenium (Se) since 1984. In 1998, the Finnish Ministry of Agriculture and Forestry raised the Se supplementation level in fertilizers from 6 to 10 mg Se/kg fertilizer. The most important sources of Se are milk, meat, and milk and meat products, which together cover nearly 70 % of the total Se intake. |

| The main aim of this study was to produce internationally comparable knowledge on the status of cultivated soils in Finland. From the soil material collected during the latest sampling process under the national monitoring programme in 1998, 338 samples were selected for this investigation. The sampling sites were situated evenly over the whole cultivated area in Finland. Samples taken as four sub-samples from the plough layer were analysed for arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), lead (Pb), mercury (Hg), nickel (Ni), selenium (Se), vanadium (V) and zinc (Zn) using aqua regia extraction according to an international standard method (ISO 11466). General statistical indicators of the analytical results of trace element concentrations are... |
