The measurements of chemical components in water of Wieprza River showed that water of this river in 2002-2003 was characterised by the high purity. The average values of most indexes were contained in the ranges of standards for the first purity class. Nevertheless considerable increase of investigation parameters was observed in zone of sewage-treatment plant and uncontrolled waste dump. The part...
The study of heavy metals concentration in the estuarine lake Gardno water and bottom sediments showed that the river Łupawa and periodic inputs of sea water exert decisive influence on forming of the water stores and bottom sediments quality in this lake. The largest concentrations of Cd, Cu, Mn, Pb and Zn were observed at river mouth into the lake region (Cd – 0.26, Cu – 3.71, Mn – 94.3, Pb – 10...
In Poland winter wheat is grown on the area of 1.600.000 ha. Most of the plant protection treatments are being done without thorough analysis of real threats from pests and diseases. The aim of the research is to develop the optimal program of wheat protection against pests and diseases based on integration of various methods of plant protection. Two programs: conventional and integrated were compared...
The content of heavy metals in peat soils of north part of Słupsk Region was low. Enrichment factors for Cd, Zn and Mn indicates on their anthropogenic origin in studied peat soils, and for Cr and Ni - natural origin. However copper may be of anthropogenic or natural origin depending on location. The farther from sea peat soils are situated the higher concentration of those metals is.
Рассматриваются результаты исследований проводимых в 1983-1985 гг. по оценке эффективности фунгицидов из группы триазолей, применяемых в виде семенной протравы и препарата для опрыскивания полей ячменя и пшеницы. Для протравливания использовался Байтан (4 вида), а для опрысков Байлетон 25 ВП, Импакт, Суми 8 и Тильт 250 ЕС. Оценивали эффективность указанных фунгицидов в борьбе с важнейшими грибными...
