| Abstract | ||||
| Soil use influence principally on physic-chemical properties through plant cover in that soil, tillage, fertilization and crop rotation. Plant cover is considered as one of the main sources of soil formation as it contribute in humus substances formation. The parts of the dead plant forms the source of the main energy and diet of the micro-organisms and animals present in the soil. These micro-organisms, in return, contribute in formation of humus. The process of humus formation is associated with the role of plant cover and its quantity and quality and also the way its accumulation and decomposition in the soil. The present research paper aimed to study the optimum utilization of the agricultural soils of the Baddia and the plant cover (forestry trees, pastoral plants and field crops) and the influence on humus accumulation and their reflection on certain physical and chemical properties of the soil .The present research revealed that there was a positive effect of the forestry trees and pastoral in the quality and quantity of the humus in the soils studied. There was also appositive effect on certain physical and chemical properties in comparison with the soils cultivated with wheat crop, in which there was an increase in humus quantity with higher concentration of humic acids compared with fulvic acids in the soils cultivated with postural and forestry plants. These lead to an improvements in mechanical composition and an increase in degree aggregation and decrease in percentage of disintegration and increase in porosity. While there was a decrease in humus quantity with predominance of fulvic acids on the humic acids in the soils cultivated with wheat resulted negatively on studied physical properties. | ||||
