Effects of Pore Fluids and Sand Particles on Electrochemical Characteristics of Sandy Soil Containing Soluble Sodium Salt

open access: yesInternational Journal of Electrochemical Science, 2020
The electrochemical impedance spectroscopy (EIS) characteristics of sandy soil and pore fluids containing different concentrations of NaCl, Na2SO4 or NaHCO3 were tested and comprehensively analysed.

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.

Engineering Characteristics and Reinforcement Approaches of Organic Sandy Soil

open access: yesAdvances in Civil Engineering, 2018
Organic sandy soil is widely distributed throughout Hainan Island. This study aimed at addressing the distribution, composition, and formation of organic sandy soil. The engineering properties of organic sandy soil were examined. The experimental results

A Rhizogenic Biostimulant Effect on Soil Fertility and Roots Growth of Turfgrass

open access: yesAgronomy, 2021
The excessive use of chemical fertilizers can lead to severe environmental damages. In recent decades, the application of biostimulants to improve soil composition and stimulate plant growth has contributed significantly to environmental preservation. In

INFLUENCE OF TEXTURE ON THE PHYSIOLOGICAL PROFILE OF SOIL ON FOREST VEGETATION [PDF]

open access: yesNatural Resources and Sustainable Development, 2022
The establishment of a wisely fertilization system in forest crops is only possible if soil characteristics are distinguished, which determine to a large extent the ability of plants to use nutrients in soil.

Experimental study on the effect of chitosan biopolymer on sandy soil stabilization

open access: yesE3S Web of Conferences, 2020
Due to the environmental impacts of conventional soil stabilization materials, such as cement, ongoing efforts have been carried out by different researchers to find alternative economical materials for substitution.

Study on the correlation of macro-fine parameters of surrounding rock in sand and cobble tunnel based on discrete element

open access: yesMaterials Research Express, 2022
As a mixture of soil and rock, the deformation of surrounding rock caused by tunnel excavation in the sandy cobble stratum is affected by the meso-structure of the stratum.

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

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 ...
