Best Management Practices for Saline and Sodic Turfgrass by Robert N. Carrow

By Robert N. Carrow

The complicated concerns desirous about the administration of saline and sodic turfgrass soils are sufficient to perplex even the main skilled website supervisor — there is not any "silver bullet" modification, therapy, or grass for salinity administration. most sensible administration Practices for Saline and Sodic Turfgrass Soils: review and Reclamation offers entire clinical rules and exact, functional administration and review thoughts for turfgrass and panorama websites. The authors use the simplest administration Practices (BMPs) thought, thought of the gold-standard administration procedure for anyone environmental factor, because it is a complete environment (holistic), science-based salinity administration method that permits all attainable administration suggestions to be thought of and applied on a site-specific foundation. They establish BMP ideas, together with irrigation procedure layout; irrigation scheduling and salinity leaching; chemical, actual, and organic amendments; cultivation; topdressing; soil amendment; sand-capping; floor and subsurface drainage recommendations; dietary practices; extra cultural practices; and ongoing tracking. The publication offers rising demanding situations, know-how, and ideas that tackle integration of salinity administration into entire website environmental or sustainable administration platforms, use of halophytic turfgrasses for non-traditional reasons, integration of geospatial and geostatistical thoughts and know-how, and integration of latest sensor expertise into day-by-day administration paradigms. Outlining a holistic BMP procedure, the publication contains medical ideas and sensible administration concepts and info particular salinity demanding situations and the good judgment in the back of each one BMP process for salinity administration, with an emphasis on real box difficulties. The publication is formatted for versatile use, with stand-alone chapters that come with outlines for fast assessment of a subject for these requiring just a simple figuring out in addition to in-depth discussions of the technology and sensible elements for these looking a extra rigorous therapy. It offers a unmarried resource for the entire info required to spot and deal with assorted forms of salinity stresses.

Sample text

It is based on a whole-systems science-based approach; intensive spatial mapping of key soil and plant characteristics using mobile sensor platforms; site-specific precision management on inputs; basic management strategies for implementation (salinity is the most complex environmental stress); and the integration of GIS + GPS + new moisture and salinity sensor technology with proactive monitoring. This concept removes a lot of the subjective decisions in management and utilizes sciencespecific technology to implement maintenance programs with salinity challenges.

Each of the primary problems present on a site requires intensive site-specific management attention on an individual basis to each stress. These four “salinity” stresses are: 1. Nutritional levels and imbalances caused by nutrient interactions and other ions in the water or soil (Chapters 4, 5, and 6) It is the mix and severity of these four salinity issues on a specific site that require a BMP plan to prevent, alleviate, or manage those stresses that are present. At the same time, any secondary problems that arise from these primary salinity stresses must be managed.

A. Soil Physical Aspects • Construction and renovation considerations: impediments to infiltration, percolation, or drainage such as calcic, clay, or rock layers; deep ripping or deep cultivation requirements prior to establishment; future cultivation equipment requirements; surface and subsurface drainage improvements; drainage outlets and salt disposal options; irrigation system requirements; presence of fluctuating or high water tables; sand-capping needs; and pre-plant physical and chemical amendments to improve soil physical condition • Identifying all salt additions: irrigation water; water table; capillary rise from salt-rich subsurface horizon; mixing of salt-laden soil during construction or dredging; fertilizers; and drainage onto the site • Other: soil texture; clay type; and soil physical analyses of rootzone media, including water-holding capacity b.
