evaluation of least limiting water range by vegetative and physiological parameters of pistachio, cv. sarakhsi, seedlings
continuous availability of soil water is an important factor for plant growth. both lack of adequate access to water in soils, or adequate oxygen in saturated soils, may reduce or even stop plant growth. to study the behavior of pistachio seedling at various moisture levels and to determine non-limiting water range for its growth, a greenhouse experiment with a completely randomized design was ...
متن کاملA Simplified Excel® Algorithm for Estimating the Least Limiting Water Range of Soils
The least limiting water range (LLWR) of soils has been employed as a methodological approach for evaluation of soil physical quality in different agricultural systems, including forestry, grasslands and major crops. However, the absence of a simplified methodology for the quantification of LLWR has hampered the popularization of its use among researchers and soil managers. Taking this into acc...
متن کاملEffects of compaction and cover crops on soil least limiting water range and air permeability
Crop rotations that include tap-rooted species of cover crops may help alleviate the deleterious effects of soil compaction on plant growth by modifying soil physical properties. We studied the effects of compaction and cover crops on the least limiting water range (LLWR) and air permeability in the surface layers of a loamy (Exp. 1) and a sandy soil (Exp. 2). There were three compaction treatm...
متن کاملperformance of three models in predicting least limiting water range in soil
the range of the soil volumetric water content at which plant growth is least limited in relation to water potential, aeration, and mechanical resistance is the least limiting water range (llwr).experimentally, measurement of llwr is expensive and time consuming. using pedotransfer functions (ptfs) can facilitate its prediction. there are, however, contradictory information about the accuracy a...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
