The paper suggests a methodology to represent overall soil pollution in a sampled area using continuous limitation scores. The interpolated heavy metal concentrations are first transformed to limitation scores using the exponential transfer function determined by using two threshold values: permissible concentration (0 limitation points) and seriously(More)
Th e paper describes the suitability of soil and weather conditions for oilseed rape production in the agricultural region of the Pannonian Plain in the Republic of Croatia. Soil suitability was estimated on the basis of the existing soil properties. Th ere are 1,169,626 ha of soils suitable for oilseed rape production in the Pannonian agricultural region(More)
It is a well known fact that nowadays planning of sustainable development and land use requires a lot of reliable and good quality information, which serves as the basis for timely and adequate decision-making. One of the most important forms of information is presented in various maps. Until recently, preparing of such data was, no doubt, a rather complex(More)
Aft er becoming self-standing state one of new needs of Croatia important for agricultural profession, farmers, policy makers and public needs was regionalization of agriculture. It is the analyse of state of agroecological conditions in agrosphere and based on results identifi cation and territorial separation of agricultural regions as parts of agrosphere(More)
Background and Purpose: Soil microorganisms participate in major processes associated with sustainable soil management and ensure cycling of nutrients required for plant production. Their role is of special importance for the dynamics of generation and decomposition of soil organic matter, and they also take part in other processes that provide soil(More)
The paper suggests a methodological framework for evaluating adequacy and usability of soil maps by analyzing the following 10 aspects: lineage, consistency, completeness, effective scale, attribute accuracy, thematic contrast, accuracy of legends, integrity, popularity, and accessibility. This framework was used to evaluate the national soil resource(More)
Pseudogleys (Stagnosols according to WRB-2014) represent the second most widespread soil type in Croatia, developed almost exclusively in its Pannonian region. Although most Croatian Pseudogleys are found on agricultural land or in agroecosystems, they usually have numerous constraints for agricultural production. Primarily, this is due to their unfavorable(More)
