(Sharpley et al., 1994; Sims et al., 1998). Restoration or remediation is needed when human impacts cause the soil system to become compromised or overloaded thereby limiting a soil’s ability to filter or transform naturally occurring chemicals (e.g., N and P) or organic wastes and ...
When drained and fertilized with nitrogen and phosphorus, they can be extremely productive and are highly valued for agriculture and forestry. However, for these soils to be productive their hydrology must be altered by drainage, which results in large freshwater intrusions into adjacent saltwater ...
a sharp decrease in crop yields after continual cultivation of the same crops or frequent use of the same field. It is most pronounced after the growing of clover (clover sickness), flax (flax sickness), and sugar beets (beet sickness). The main causes of soil depletion are the accumulation...
The following are examples of suitable topics within the scope of the journal of Soil and Tillage Research: The agricultural and biosystems engineering associated with tillage (including no-tillage, reduced-tillage and direct drilling), irrigation and drainage, crops and crop rotations, fertilization, ...

(dyed with fluorescein solution of 0.01 mM) as initial condition. The upper side of each chip was open to the atmosphere, and the lower side was open for drainage. The air and water phases were monitored during the drainage process using a CCD camera (Ximea, Germany), and the ...
(2) and (3), we conducted laboratory drainage experiments using microfluidic chips with different grain sizes λc, in which we compared simulated and observed water patch properties (Methods and Supplementary Fig. 2c, d). Soil heterotrophic respiration at the patch scale Following the results of...
showed that surface flow increases with slope angle but offered little discussion on lateral soil moisture movement. initial increases in water storage are observed on steeper terrains, followed by sharp decreases, with a diminishing recharge coefficient as slope gradient increases (huang et al. 2013 ...
When she showed me her newly planted lavender bed, she said that lavender likes sandy soil with good drainage. She recommended a mix of 1 part sand, 1 part potting soil, & 1 part compost. She recommended to water daily at first & then wait a day, water, & then 2 days, water, & ...
This alternation of soil is most often observed in the chestnut and brown semidesert soil zone, where comparatively small variations in moisture, usually related to microrelief, cause sharp changes in conditions of development for soils and vegetation. The number of types of soils in the soil com...
