Harvey et al. (1) recently presented detailed vertical profiles for groundwater arsenic and a suite of other water and sediment properties from a study site in southern Bangladesh. This information, supplemented with carbon isotopic data (C and C) for dissolved organic carbon (DOC) and dissolved inorganic carbon (DIC), was used to support the notion that the DOC introduced into subsurface aquif...

Cotton (Gossypium hirsutum L.) yield and quality responses to irrigation have not been described for conservation management systems that growers are rapidly adopting. We conducted a field experiment from 2001–2003 in the Tennessee Valley near Belle Mina, AL on a Decatur silt loam (fine, kaolinitic, thermic Rhodic Paleudults) to examine how irrigation regimes and tillage systems affect ginning ...

Recently, water scarcity has become a serious social problem caused by global climate change. In agricultural usage, subsurface irrigation techniques can be an alternative method to save and improve the productivity quality of crops. The technique supplies burying hose 30 cm underground rather than placing it on ground (topsoil), effectively preventing evaporation loss at soil surface. this stu...

Potatoes are a high-value crop with shallow root system and high fertilizer requirements. The primary emphasis in potato production is minimizing nitrogen-leaching losses from the zone through fertigation. Therefore, field experiment was conducted for two consecutive years, 2018–2019 2019–2020 to assess effect of nitrogen irrigation amount frequency on tuber yield, water balance components prod...
