Quantitative description of the spatial variability of soil hydraulic characteristics is crucial for planning, management and the optimum application. Field measurement of infiltration is very expensive, time-consuming and laborious. Soil structure also important effects on water infiltration in the soil. The objectives of this study were to determine the spatial variability of water infiltrati...
Landslides caused many ecological processes at landscape to local scales, including the ecological succession processes. The landslides geological characteristics and their management as physical risks are truly documented but the ecological processes that are caused by landslides and their relations to efforts to restore stability to unstable slopes, have not been well studied. In this study, ...
soil productivity is generally associated with poor nutrient status and the physical condition of the soil, but the effect of soil mineralogy on soil productivity has received little attention. in this qualitative study, interactions between mineralogy and physico-chemistry and their role on the productivity of two luvisols, an arenosol and a vertisol are investigated. minerals identified in th...
Iron oxide-coated strips (Pi) can serve as a sink to continuously remove P from solution. In this way, probably, P extraction is analogous to P absorption by plant root. The objective of this study was to evaluate the iron oxide-coated paper strips to estimate the availability of soil P of corn (Zea mays) grown under greenhouse conditions in some soils of Hamadan Province. Sixteen soil samples ...
The effect of soil properties like adsorption, desorption, movement and distribution of endosulfan (1, 2, 3, 4, 7, 7-hexachlorobicyclo (2, 2, 1)-2-heptene-5, 6-bisoxymethlene sulfite) in two tropical soils, sandy loam and sandy clay soil from Mysore, Karnataka state were studied respectively. The results indicated that soils with different physico-chemical properties have different effects on t...
A study of physico-chemical properties, the instrumental measurement of colour and texture was carried out on ten di erent brands of traditional Croatian dry fermented sausage known as Slavonian Kulen. Basic physico-chemical properties showed large variability (p < 0.05), especially the collagen content. This can be related to di erent recipes used by di erent producers, and di erent stages of ...
Arbuscular mycorrhizal fungi (AMF) colonize land plants in every ecosystem, even extreme conditions such as saline soils. In the present work we report for the first time the mycorrhizal status and the vertical fungal distribution of AMF spores present in the rhizospheric soil samples of four species of Chenopodiaceae (Allenrolfea patagonica, Atriplex argentina, Heterostachys ritteriana and Sua...
