Mapping Detailed Soil Property Using Small Scale Soil Type Maps and Sparse Typical Samples
Soil type maps at the scale of 1..1 000 000 are used extensively to provide soil spatial distribution information for soil erosion assessment and watershed management models in China. However, the soil property maps produced through conventional direct linking method usually suffer low accuracy as well as the lack of spatial details within a soil type polygon. This paper presents an effective m...
متن کاملSoil property mapping over large areas using sparse ad-hoc samples
This paper presents a new approach to predict soil properties and quantify uncertainty in the derived soil property maps over large areas using sparse and ad-hoc samples. According to the soil-landscape model, each soil sample contains corresponding relationships between soil and environment conditions. Under the assumption that the more similar the environment conditions between two locations ...

متن کاملAssessing Relation of Soil Hydrophobicity and Soil Water Content and Determining Threshold Moisture of Organic Soil Samples
Soil water content is the most effective factor associated with the hydrophobic and hydrophilic changes in a soil. Water repellency in soils, is not a permanent feature; it can be reached in the dry season and reduced or eliminated in the wet season It can be said that in terms of moisture, there is a critical region that is defined as the threshold moisture content, where in lower moisture, th...
