Spatial Characteristics of Claypan Soil Properties in an Agricultural Field

Spatial variability in soil properties has long been observed within uniformly managed fields. Understanding the spatial characteristics of soil properties would be helpful in understanding soil–landscape relationships and in the development of site-specific management. The primary objective of this research was to quantify the spatial characteristics of claypan soil properties for a 4-ha agric...

Soil Phosphorus and Agricultural Development in the Leeward Kohala Field System, Island of Hawai‘i

The leeward Kohala Field System on the island of Hawai‘i was one of the most intensive pre–European contact dryland agricultural systems. Archaeological and soil analysis has documented changes in soil nutrients over time. Soils were collected under agricultural field walls of different relative ages within the Kohala Field System. These field walls preserved soil from the time of their constru...

Assessment of ASTER Data for Soils Investigation Using Field Data and GIS in Damghan Playa

In order to assess the satellite data for soil investigation, ASTER digital data 20 June 2006, field study and phisiochemical properties of soil, were analyzed. All landcover classes including soils are classified based onmorphological and physico-chemical characteristics. Images were geocorrected and photomorphic units were selected based upon visual interpretation and sampling in study area. ...

Automatic Guidance of Agricultural Field Machinery

Systems developed to automatically guide agricultural field machinery were previously restricted to special applications because no universal sensor system could be provided. Recently this has changed due to the tremendous progress in electronics performance and performance/price ratio. Machine vision as well as satellite positioning systems promise to serve as an appropriate and universal sens...
