The river absorption capacity determination as a tool to evaluate state of surface water [PDF]

open access: yesHydrology and Earth System Sciences, 2018
In order to complete a thorough and systematic assessment of water quality, it is useful to measure the absorption capacity of a river. Absorption capacity is understood as a pollution load introduced into river water that will not cause permanent and

The Efficacy of Acidified Drip Irrigation for Reducing Soil pH in Remediating Heavy Saline Coastal Soils

open access: yesGuan'gai paishui xuebao, 2021
【Background】 Heavy saline coastal soil is a valuable land resource but its high salt content and sticky texture, along with its high sodium adsorption ratio and shallow groundwater table, makes it difficult to remediate.

Effects of Matric Potential Threhold Used for Control of Shallow Drip Irrigaion on Growth and Yield of Alfalfa

open access: yesGuan'gai paishui xuebao, 2023
【Objective】 Matric potential measured at a position below the emitter is often used as a threshold to control drip irrigation. In this paper we investigate the effect of the threshold on growth and yield of alfalfa irrigted by shallow drip irrigation ...
