Morphology of rain water channelization in systematically varied model sandy soils [PDF]

open access: yes, 2014
We visualize the formation of fingered flow in dry model sandy soils under different raining conditions using a quasi-2d experimental set-up, and systematically determine the impact of soil grain diameter and surface wetting property on water ...

Multiple benefits of manure: the key to maintenance of soil fertility and restoration of depleted sandy soils on African smallholder farms [PDF]

open access: yes, 2008
Manure is a key nutrient resource on smallholder farms in the tropics, especially on poorly buffered sandy soils, due to its multiple benefits for soil fertility. Farmers preferentially apply manure to fields closest to homesteads (homefields), which are

Characterizing and Modeling Tropical Sandy Soils through VisNIR-SWIR, MIR Spectroscopy, and X-ray Fluorescence

open access: yesRemote Sensing, 2022
Despite occupying a large area of the globe and being the next agricultural frontier, sandy soils are seldom explored in scientific studies. Considering the high capacity of remote sensing in soil characterization, this work aimed to: (i) characterize ...

Impact of mechanized harvesting on compaction of sandy and clayey forest soils : results of a meta-analysis [PDF]

open access: yes, 2012
Nowadays, harvest operations are predominantly performed fully mechanized using heavy tractors or forestry machines. The resulting soil compaction may negatively affect the soil ecosystem.

Effect of Cohesive and Non-Cohesive Soils on Equilibrium Scour Depth

open access: yesTikrit Journal of Engineering Sciences, 2007
In this research ,the effect of cohesive soils ( clay ) and non –cohesive soils sand on equilibrium scour depth was studied .Experiments were carried out on two types of clay and two types of sand as a bed material using an obstruction ( pier ) to create

Soil organic matter influences the agronomic efficiency of boron fertilizers in sandy Oxisol cultivated with soybean [PDF]

open access: yesScientia Agricola
Boron (B) is readily leached from the soil, depending on the soil texture, soil organic matter (OM) content, and the fertilizer source used. This can restrict B uptake by plants. Therefore, we investigated the most adequate B source for soybeans grown in

Influence of drainage status on soil and water chemistry, litter decomposition and soil respiration in central Amazonian forests on sandy soils [PDF]

open access: yes, 2011
Central Amazonian rainforest landscape supports a mosaic of tall terra firme rainforest and ecotone campinarana, riparian and campina forests, reflecting topography-induced variations in soil, nutrient and drainage conditions.

Interactions between metals and soil organic matter in various particle size fractions of soil contaminated with waste water [PDF]

open access: yes, 2009
Only scarce field studies concern the consequences of natural soil organic matter (SOM) and metal interactions on SOM dynamics in soils. We investigated the interactions of four metals (Pb, Zn, Cu and Cd) with the SOM associated to five different size ...

Water Movement and Finger Flow Characterization in Homogeneous Water-Repellent Soils

open access: yesVadose Zone Journal, 2018
Soil water repellency (SWR) is a widespread property in soils around the world. It influences soil water movement and causes unstable flow. The mechanics of finger flow occurrence in water-repellent soils are not clearly understood.
