introduction: spatial variation of soil properties is significantly influenced by numerous environmental factors such as landscape features, including position, topography, slope gradient and aspect, parent material, climate and vegetation. soil properties vary spatially in south- and north-facing hill slopes. this factor (different slope aspects) can affect the distribution of soil organic mat...

The objective of this work was to compare two different methods concerning their efficiency in a selection of soybean genotypes for Al tolerance. Selection for aluminium tolerance is necessary to the full adaptation of the soybean crop in the acid soils of the Brazilian Savannahs (Cerrados). Field techniques, however, are laborious and time consuming. The present results indicate that hill plot...

Introduction The hill environment is characterized by high rainfall and wind speeds and a short growing season of sparse pastures. For the purposes of this paper, land classified for statutory purposes as hill land but which is strictly improved upland or upland capable of improvement is excluded from the discussion. The objective here is to examine the effects of nutrition on performance with ...

Following the accident at the nuclear power plant in Chernobyl in 1986, great volumes of Cs were distributed over large parts of the former Soviet Union and Europe. Over Scotland, radiocaesium was deposited as wet deposition. Due to the relatively long physical half-life of 30 years, there are still measurable activity concentrations in the natural environment. This study was made on two organi...

The impact and cost of synthetic fertilizers as well as their associated risks on the environmental safety was becoming unaffordable. To alleviate these problems, integrating this synthetic fertilizers with easily available and an environment friendly compound like bio-char is of very high significance towards meeting our goal of increasing agricultural production and ensuring food security. Th...
