Aflaj’s Irrigation Water Demand/Supply Ratio: Two Case Studies
Due to the geographical location of Oman in an arid zone, agricultural production depends fully on irrigation. The traditional irrigation systems (Aflaj, sing. falaj) supply more than one third of water for agriculture. Falaj is defined in the context of

Mixed nitrate and ammonium supply improves maize growth and leaf water status by regulating concentration ratios of phytohormones in the xylem sap [PDF]
Abstract The use of mixed nitrate and ammonium supply (mixed-N) as a nitrogen source can improve plant growth. Phytohormones in the xylem sap are involved in root-shoot signaling and regulation of plant growth and development. However, the role of xylem sap phytohormones in the shoot growth with mixed-N supply is poorly understood.

Application of stable isotope ratios in drinking water supply system of Ljubljana, Slovenia
<p>The key to understand the deterioration of the quality of urban water resources is to know the impact of urbanization on the entire waterway, which can change dramatically during the extreme climatic events. Various geochemical parameters, including stable isotope ratios of light elements (H, O, C), represent an important tool

Ecological correlation analysis was made between the source of drinking water and standardized incidence ratios (SIRs) of malignant neoplasms registered in Niigata, Japan. The purpose of this study was to find out some clues for generating a working hypothesis that the contamination of drinking water with environmental chemicals especially of endocrine

Effects of mycorrhizal inoculant, N:P supply ratio, and water depth on the growth and biomass allocation of three wetland plant species [PDF]
In the greenhouse, we investigated the growth and biomass allocation of three juvenile wetland species ( Carex tribuloides Wahl., Phalaris arundinacea L., and Rumex orbiculatus Gray) under three different water depths (–4, 0, and +2 cm relative to the soil surface), three N:P supply ratios (1:30, 1:1, 30:1), and two mycorrhizal inoculant treatments ...

On the optimal ratio of surface and groundwater in water supply of the population in Ukraine
The Law of Ukraine “On Drinking Water, Drinking Water Supply and Sewage” contains a norm regarding “observance of an optimal balance of surface and groundwater use for drinking water supply”, although it is not defined exactly what this balance should be.

Anthropogenic activities are changing global precipitation regimes and result in many middle latitude arid and semiarid regions experiencing less precipitation and more extreme weather events. However, little is known about the response of active ingredient accumulation in the medicinal herb Plantago depressa Willd.
