Soil moisture is an important parameter for agricultural production. Efficient and accurate monitoring of soil moisture is an important link to ensure the safety of agricultural production. Remote sen...
The article 3.4 of the Kyoto Protocol acknowledges agriculture soils as a potential sink for soil organic carbon (SOC). To estimate current and potential SOC on a broad scale for these potential sin...
The hand ling of exo-atmospheric TM bidate (march and September 1989) reflectance data was used for cartographying the land, using multispectral classification algorithms of the type supervised (Lik...
North Bohemia belongs to one of the most heavily industrialized and polluted regions in Europe. The enormous acid deposition which culminated in the 1970s has largely contributed to the accelerated ac...
The development of Podzols is conditioned by many factors. One of them is vegetation cover. The aim of this study was to examine in detail special chemical properties, micromorphological features and ...
One peculiar feature of the inland valleys abundant in West Africa is their site-specific hydrology, underlain mainly by the prevailing landforms and topography. Development and management of these la...
The Hruby Jeseník Natural Forest Region (NFR) is a border mountain territory which belongs to the areas most heavily impacted by air pollution in the Czech Republic. This paper compares results for so...
Erosion, which is one of the most important exogenous processes forming the landscape, has become a main degradation factor affecting agroecosystems. One of the direct erosion effects is a change in t...
This paper is focused on the Jizera Mountains as a region strongly influenced by man in the past. The structure of the natural forest was changed. Species monocultures with similar tree ages were plan...
Anthropogenic soils are formed by human activities. The contents of potentially risk elements are one of the most important criteria of the exploitability of such soils for the agricultural production...
A comparative survey of the weed species present in field plots and edges was performed in fields at Zavalla (Santa Fe) Argentina in the soybean central region of the country in order to determine cha...
Recently soils have gained more attention within the global change debate as the largest terrestrial carbon (C) pool. Different soils and vegetation types have substantial impacts on many of the proce...
The P-fixing capacity of a soil governs the P-nutrition of crop plants. P-nutrition of the crop plant is more a soil problem and a higher dose of phosphatic fertilizer is necessary for soils having hi...
In irrigation schemes under rotational water supply in semiarid region, the water allocation and irrigation scheduling are often based on a fixed-area proportionate water depth with every irrigation c...
Human induced pressures on the natural resources are still in progress and the conservation efforts, too. The need for sufficient knowledge and data for the decision makers is obvious. This study is a...
