Currently accepted pedotransfer functions show negligible effect of management-induced changes to soil organic carbon (SOC) on plant available water holding capacity (?AWHC), while some studies the ability substantially increase ?AWHC through management. The Soil Health Institute's North America Project Evaluate Measurements measured content at field using intact cores across 124 long-term rese...

in order to study of effects of deficit irrigation on morphological traits and growth indices variation of corn forage (sc. 704) in rasht region, an experiment based on randomized complete design with four treatments and three replication was conducted in 2007 growing season, at research farm of faculty of agriculture, university of guilan. experimental treatments consisted of: no-irrigation, 1...

The warming climate is rapidly changing the circumpolar region, presenting new opportunities and challenges for agricultural production in South Greenland. projected to increase frequency of drought periods, but little known about soil–water retention (SWR) plant available water (PAW) soils region. This study aimed measure SWR PAW Greenlandic evaluate effect organic carbon (OC) clay (CL) conten...

Robust assessment of crop water availability requires effective integration soil moisture data within the range field capacity (θFC) to permanent wilting point (θPWP). Emerging needs for spatiotemporally dynamic θFC and θPWP are difficult achieve with lab determinations. Therefore, we used long-term from 182 sites across United States evaluate whether extremes defined by 95th 5th percentiles re...
