Accessing\u00a0spatial variability of soil properties\u00a0often require high-density and repetitious sampling, which is costly, time-consuming, and labor-intensive. One of the challenges facing the adoption of precision agriculture technology is the identification of productivity-related variability of soil properties accurately and cost-effectively.<\/p>\n<p><img decoding=\"async\" src=\"http:\/\/www.landviser.net\/webfm_send\/171\" alt=\"Low ER indicates low cranberry yield\" \/><\/p>\n<p class=\"rtejustify\">The application of the geophysical methods of electrical resistivity makes it possible to define areas of electrically contrasting soils, which have distinct properties and, therefore, should be used in agriculture in different ways. Electrical resistivity is a composite characteristic of soils, which generally related to soil\u00a0texture,\u00a0stone,\u00a0salt, and\u00a0humus contents, and arrangement of the genetic soil horizons. This is the complex of the factors, which directly influence yield of the most of the crops. The advantage of measuring electrical resistivity is that it can be measured directly in the field without actually taking of soil samples and analyzing them in the laboratory. Thus, the implication of the electrical resistivity techniques of soil characterization can tremendously decrease time and labor, required to delineate management zones within the fields.<\/p>\n<p class=\"rtejustify\"><img decoding=\"async\" src=\"http:\/\/www.landviser.net\/webfm_send\/172\" alt=\"improving drainage on cranberry beds\" \/>Figure above on the right shows that lower soil electrical resistivity generally corresponds to the decrease in cranberry yield. The data were obtained at 216 sampling locations with\u00a0<a href=\"http:\/\/landviser.biz\/dotcomsandbox\/landmapper-erm-01-simple-handheld-resistivity-meter\/\">LandMapper ERM-03<\/a>\u00a0and interpolated into the map with commercial software, such as ArcView (ESRI, Inc.) and GS+ (Gamma Design Software, Inc.). Low electrical resistivity outlines the low-lying areas within the field with reduced conditions (toxic iron Fe+2) and prone to Phytophthora root rot disease, which caused a decrease in cranberry yield. Remediations including removing clogged drainage pipes, digging extra trenches and re-filling them with coarse gravel to improve drainage.<\/p>\n<p>\u00a0<\/p>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>One of the\u00a0most important issues in precision agriculture\u00a0is to develop site-specific principles of crop management based on the variability of soil and hydrological properties.
