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 inventory in Croatia and to find out why th...

one of the serious problems of iran’s watersheds is soil erosion and can be considered as one of the main obstacles to achieve sustainable agricultural development and natural resources. in most countries of the world, because of absence of accurate data for the sediment erosion, deposition utilizing models to estimate erosion is inevitable. in order to apply effective management in natural res...

of stereoscopic landscape analysis, and then determine the soil types that occur in each map unit by field inspecA method to enhance manual landform delineation using phototion of the soil at representative sites. A common inspecinterpretation to map a larger area is described. Conventional aerial tion density is one observation per one to four map photo-interpretation (API) maps using a geo-pe...

In this paper, the El-Hames empirical method was used to determine the peak runoff flow in Iranshahr catchment. The El-Hames method is based on morphological parameters and SCS Curve Number of the studied area. The implementing was processed by collecting the required data including soil type and vegetation cover, land use maps, digital elevation model and satellite images from the associated i...

Soil bacterial communities play an important role in nutrient recycling and storage in terrestrial ecosystems. Loess soils are one of the most important soil resources for maintaining the stability of vegetation ecosystems and are mainly distributed in northwest China. Estimating the distributions and affecting factors of soil bacterial communities associated with various types of vegetation wi...

Research about N management in corn has rapidly advanced during the last 10 years. Farmers and agronomists can use different recommendation systems such as the regional N recommendations that are based on yield response and profit optimization (Sawyer et al., 2006) or in-season N diagnostics tools such as chlorophyll meters or crop canopy sensors (Scharf and Lory, 2002; Holland and Sheperds, 20...

Accurate and detailed spatial soil information is essential for environmental modelling, risk assessment and decision making. The use of Remote Sensing data as secondary sources of information in digital soil mapping has been found to be cost effective and less time consuming compared to traditional soil mapping approaches. But the potentials of Remote Sensing data in improving knowledge of loc...
