Updated Guidelines for Soil Selection and Improvements for Irrigated Pecan Production: Alluvial Soils
Soil types (texture and profile configuration), soil salinity, sodicity, subsoil drainage, and fluctuating high water tables, have the pronounced effect on tree performance in pecan orchards established in alluvial soils. This paper outlines the soil types and soil properties suited or not suited for irrigated pecan production, using the decades-long experience in the El Paso Valley, Texas. Various ways to improve undesirable soils, such as chiseling, trenching, and soil profile modification are also briefly discussed. The information presented would be useful for planning orchard development in alluvial basins of the West.
