Microwave device for soil heating

Slowinski, K., University of Agriculture [2009]

There are numerous applications for soil heating. Thawing soil prior to excavation, chemical decontamination, land mine clearance and soil sterilization are just a few potential uses. Microwave heating has been applied to various agricultural problems since the 1960s. In particular, treatment of soils as a method of weed and pathogen control has been proposed for some time. In Europe, microwav ...

Sustainable landscape management of the Tatry Biosphere Reserve of UNESCO

Izakovičová, Z., Slovak Academy of Sciences et al. [2009]

The paper is aimed at the presentation of the proposal of sustainable landscape management of the Tatry BR in consideration of landscape and ecological properties of the area. On November 19, 2004 a massive windstorm swept through the area of the transboundary Tatry Biosphere Reserve (Tatry BR) shared by Slovakia and Poland. The windstorm strongly harmed and locally completely damaged 14% of t ...

Effects of land use types on soil chemical properties in smallholder farmers of central highland Ethiopia

Duguma, L. A., University of Natural Resources and Applied Life Sciences et al. [2010]

A study was conducted in Suba area, central highland Ethiopia to assess the variability in soil chemical properties between homesteads, small-scale woodlots, pasturelands, and cereal farms and see the relative soil improvement effects of the first three land uses under farmers management compared to the dominantly practiced cereal farming. Soil samples collected from four land uses at two dept ...

The contribution is focused upon detail production-ecological analysis of the total herb layer biomass (above-belowground) in the different age stages of the willow stands (soft-wood floodplain forest of the Salici-Populetum association) in the Danube river inundation. The basic results vary between 1.3 to 3.1 t per ha according to the age structure and herb layer cover. At all studied forest ...

Mercury contamination of tissues and organs of pike

Żarski, T. P., Warsaw University of Life Science et al. [2010]

The work aimed at determining in which predatory fish tissue mercury is cumulating to the highest degree. Mercury content was investigated in particular tissues and organs of pike. Fishes bought at random in Warsaw fish wholesale company in November 2005 comprised the experimental material. Before sampling fishes were weighed and measured. The samples of the following tissues were collected fo ...

Effects of liming and NPK-fertilization on the soil and fine roots in a Norway spruce stand

Konôpka, B., National Forest Centre - Forest Research Institute Zvolen et al. [2010]

The main objective of the paper is the quantification of liming (CaO + MgO) and/or NPK-fertilization effects on soil chemical properties and fine root parameters in an 85-year-old Norway spruce (Picea abies L. Karst.) stand in the Nízke Tatry Mts, Central Slovakia. The analyses of pH and soil solution Ca/Al molar ratio were carried out two and six years after applying the amelioration material ...

Distribution of bacterivorous nematodes along the distance gradient from a thermal power station

Vijay Vikram Singh Tomar, Aligarh Muslim University et al. [2010]

The distribution of bacterivorous nematode genera along a distance gradient from a 50 years old Thermal power station was studied. Sampling distances were 500m (A), 1000m (B), 2000m (C) and 4000m (D) from the station. Soil chemical properties were analyzed and the abundance of nematode genera were studied in relation to pH, available carbon, available potash and available phosphates in the soi ...

Investigation on the influence of fertilization on enlargement of leaf dimensions and seed production of Moehringia trinervia was carried out in July 2006 on Vistula spit, within the largest European breeding colony of cormorant Phalacrocorax carbo, where multiple enhancement of NPK in the soil due to deposition of guano was noted. The control sample was taken from place located ca. 500 m away ...
