Sodic soils have low organic carbon content, microbial load and their activities which were the biological indicators of soil health. Soil organic carbon is the kay factor which derives the soil functions. A field experiment was conducted to study the effect of different amendments and micronutrient mixture on soil biological properties. Gypsum+GM, DSW (distillery spent wash) and GLM (Glyricidi...

Sulphur status of some soils in Edo Central, Nigeria was evaluated in five different locations; Ekpoma, Irrua, Uromi, Ubiaja and Agbede. The area lies within the derived savanna-forest transitional zone. Surface soil samples (0 – 15 cm) collected from the five localities wasanalyzed for their physico-chemical properties, inorganic, organic and total sulphur contents. Results showed that inorgan...

In this study, the natural Cu background concentration and Cu natural and anthropogenic contamination in soil, water and crop were investigated systematically in Huangshi area. The results show that regional geology is the dominant factor controlling the natural Cu background concentration in soil and water, and that pH is important to control the vertical distribution of Cu in soil under the s...

Background and Objective:  Polltion of food chain components such as vegetables to heavy metals is one of the important environmental problems. Remediation management of these metals especially Cd is very important. Thus, this research was done to investigate the effect of Arak municipal waste compost enriched with tire rubber ash on decreasing spinach Cd concentration in a Cd polluted soil. M...

Plant diversity and vegetation distribution in an area are related to the soil physical and chemical properties. The knowledge of relationships between species diversityand soil parameteris essential for sustainable ecosystem management. This study was conducted to investigate the relationships between soil factors and species diversity indices in the protected rangelands of Lashgardar, Malayer...

Terraces are old geomorphic surfaces that are not related to present streams and are best places to study the effect of time on soil formation (chronosequence). This research was carried out to study some physico-chemical parameters especially different forms of iron as soil development indices on terraces of Karaj River in Hassan-Abad, southern Tehran. To determine soil development indices in ...

The response of soil properties to vegetation types is still not well understood and the relationship between vegetation types and soil properties has not been quantified in highland grasslands. A field experiment was conducted in highland grassland of the Loess Plateau in China to study the distribution of soil properties under different vegetation. 22 plant communities totaling 17 species tha...

A set of countermeasures aimed at reducing Cs uptake by plant products includes agrochemical measures based on changes in the soil properties after the application of ameliorants. The dynamic models for studying the effect of the application of potassium fertilizers and dolomite powder on Cs accumulation in plants are presented. Conceptual approaches to the development of models are based on th...
