Determination of Agricultural Sulfur Effects on the Soil Structure Using Fractal Geometery and Aggregate Stability Indices
Due to unsuitable soil physical conditions, calcareous soils, and the existence of a huge amount of sulfur in the country, the study of sulfur effects on the soil structure and other soil properties is necessary. Therefore, the effects of different rates of sulfur including: 0, 750, 1500 and 3000 kg/ha, when accompanied by Halothiobacillus neapolitanus bacteria, on the soil properties in the co...
متن کاملSustainability assessment of slash-and-burn and fire-free agriculture in Northeastern Pará, Brazil
Slash and burn agriculture, largely dependent on the duration of the fallow period to restore the productivity of the land, is extensively practiced by small landholders in Pará State, Brazil. Due to a mounting demographic pressure, fallow periods have been shortened, and signs of agronomic and ecological failure such as decreasing crop yields and structural and compositional depletion of the s...

متن کاملSoil health in agricultural systems.
Soil health is presented as an integrative property that reflects the capacity of soil to respond to agricultural intervention, so that it continues to support both the agricultural production and the provision of other ecosystem services. The major challenge within sustainable soil management is to conserve ecosystem service delivery while optimizing agricultural yields. It is proposed that so...
