The Non‐Limiting and Least Limiting Water Ranges for Soil Nitrogen Mineralization
Soil Science Society of America Journal, 2003A better understanding of factors controlling N mineralization would improve our ability to estimate fertilizer requirements more accurately. Net N mineralization approaches a small reaction rate at low and high water contents, giving rise to lower and upper limiting water contents and the least limiting water range (LLWR).

Effect of Soil Water Content Variation on the Least Limiting Water Range
Soil Science Society of America Journal, 1997Abstract The least limiting water range (LLWR), a proposed structural quality index, is the range in soil water content within which plant growth is least limited by water potential, aeration, and mechanical resistance.

Effect of water salinity and sodicity on soil least limiting water range
Soil Science Society of America JournalAbstract This study aimed to evaluate the effects of water salinity and sodicity on the least limiting water range (LLWR) of two clay loam and sandy loam soils. The undisturbed soil samples were subjected to different water qualities, including three levels of sodium adsorption ratio (SAR, 1, 5, and 12) and ...

The least limiting water range (LLWR) was introduced as an integrated soil water content indicator, measuring the impact of mechanical impedance, oxygen and water availability on water uptake and crop growth. However, a rigorous definition of the upper limit of the LLWR using plant physiological and soil physical concepts was not given. We introduce in

Least limiting water range for two conservation agriculture cropping systems in India
Soil and Tillage Research, 2015Abstract Deterioration of the soil physical environment is a major reason for decreasing crop productivity in the western Indo-Gangetic Plains (IGP) of India. To address this problem, the least limiting water range (LLWR) for two conservation agricultural (CA) practices was quantified.

No-till has many environmental advantages, but concerns are growing about vehicle-induced topsoil compaction limiting crop growth. We performed a wheeling experiment in a long-term no-till field on an Oxisol with sandy loam texture. The objectives were to measure changes in soil bulk density and corresponding impacts on the least limiting water range ...

Abstract The objective of this research was to identify the mechanism of how tillage methods affect maize ( Zea mays L.) production using a modified least limiting water range (LLWR) method. The LLWR is the range of soil water content within which the water and O

Least limiting water range and crop yields as affected by crop rotations and tillage
Soil Use and Management, 2010Abstract Crop rotation and the maintenance of plant residues over the soil can increase soil water storage capacity. Root access to water and nutrients depends on soil physical characteristics that may be expressed in the Least Limiting Water Range (LLWR) concept.

Least limiting water range: a potential indicator of physical quality of forest soils
Australian Journal of Soil Research, 2000The interactions of the 4 basic soil physical properties—volumetric water content, matric potential, soil strength, and air-filled porosity—were investigated over a range of contrasting textures and for 3 compaction levels of 4 forest soils in New Zealand, using linear and non-linear regression methods.
