% of a water-retention agent, 10%-50% of humus soil, 1%-10% of sheep manure, and the balance being planting soil, wherein a total mass percentage of the above components is 100%; and 200-300 grass seeds are uniformly distributed in every kilogram of the water-retention nutrient soil....
Estimating soil water retention in a selected range of soil pores using tension disc infiltrometer data This observation strongly suggests that the proposed method can be applied for the in situ measurement of water retention and pore size in field soils. ... Y Yoon,JG Kim,S Hyun - 《Soil ...

2.4Water retention The repulsion of water by the hydrophobic group of organic molecules that are present in the wastewaters or are formed during wastewater decomposition (Bisdom et al., 1993; Tarchitzky et al., 2007) temporarily reduces the ability of the soil to retain water. Thus, the avail...

The exact characterization of soil hydraulic properties is essential for various purposes, such as agricultural and groundwater management. Various laboratory methods for the determination of soil water retention characteristics are frequently applied. Standard methods comprise: (i) the hanging-water column...
The prediction of spatial and temporal variations in the soil water regime provides the basis for a proposed soil survey interpretive system. A water retention model estimates the boundary desorption curve from saturation to pF 4.2 for mineral soils in situ using limited soil physical data. -from ...
Since reported data show ambiguities due to various feedstock, pyrolysis parameters, soil characteristics, and a highly variable change in water retention capacity (WRC), robust statistical methods were applied to compare the reported data from previous studies. The results revealed that biochar ...
