While it is well known that soil moisture directly affects microbial activity and soil organic matter (SOM) decomposition, it is unclear if the presence of plants alters these effects through rhizosphere processes. We studied soil moisture effects on SOM decomposition with and without sunflower and soybean. Plants were grown in two different soil types with soil moisture contents of 45% and 85%...

in this study, the pattern of changes in the values of soil electrical conductivity (ec) and soil temperature (t) under full irrigation treatment (fi) as compared with prd75 and prd55 treatments (partial root-zone drying which received 75 % and 55% water of fi at each irrigation event) was investigated in 1389 on a maize filed in sari university of agricultural sciences and natural resources. r...

soil compaction has become a widespread problem in the world and it is considered as one of the main factors affecting land degradation in arid and semi-arid agricultural land. the aim of this study was to investigate the effects of soil compaction on soil carbon and nitrogen sequestration, physical (aggregate stability, saturated soil moisture content, bulk density, and porosity) and chemical ...

application of soil conditioners for remediation of saline- sodic soils is one of the common methods for improving soil properties in arid and semi-arid regions. in order to study the effect of soil conditioners on retention of soil moisture content, an experiment was carried out based on randomized complete block design with three replications in a saline-sodic sandy clay loam soil. the treatm...

effect of different application rates of municipal solid waste compost (mswc) and biochars derived from rice straw (rsb) and sugarcane straw (ssb) on the nutrients concentration of rice plant leaves was studied. the mswc application rates were 0, 10, 20 and 30 g mswc per kg soil and the applied levels of the biochars treatments were 0, 3 and 6 g biochars per kg soil. the experiment was conducte...

The hydrogen peroxide treatment was able to remediate chlorophenols, polycyclic aromatic hydrocarbons, diesel and transformer oil contaminated soil. Chemical treatment of contaminants adsorbed in peat resulted in lower contaminants’ removal and required higher addition of chemicals than the treatment of contaminants in sand. The hydrogen peroxide treatment was found to be feasible for soil reme...

In order to understanding of the VAM effects on functions and nutrition of the corn, a research was conducted in Agricultural Research Center of Safi Abad, Khouzestan. The experiment was carried out based randomized complete block design at four replications. The treatments contain Mycorrhiza Fungi and phosphorous includes: A: Phosphorus according to soil test. B: VAM + Phosphorus according to ...
