It has been observed in the present study that when spores of Trichoderma harzianum (Th-2) isolate were applied in the sandy clay loam soil and continuously incubated for 4 months at 25C and 35C and at three water potentials, -0.03 MPa, -0.3 MPa and <-50 MPa, it has resulted in significantly reduced (P<0.05), growth of Fusarium oxysporum ciceri (Foc) on branches of chickpea plant. The pathogen ...

Regional development in Panimbang District, Banten Province, Indonesia, is executed so that the tourism area not centered solely on west coast of Pandeglang but also surrounding area. The carried out stages from government offices, education facilities, and public facilities. One facilities to be built a garden. This study aimed evaluate condition soil layers fertility for garden construction. ...

Sodic soil is one of the most common problems of limiting agricultural production that related on irrigation. Saturated hydraulic conductivity is one of hydrodynamic characteristics in evaluating transmission flow through underground levels. To investigate the role of increment of exchangeable sodium in hydraulic conductivity changes (as characterized by the mobility of water in soil) an experi...

The roles of NH.-N diffusion, NH.-N oxidation, NO3-N diffusion, and NO3-N reduction in controlling N loss from continuously flooded soil were evaluated in independent experiments. Applied NH,-N moved from zones of high NH4-N concentration to the zones of low NH4-N concentration. The average diffusion coefficient (D) for NH.-N in flooded soil ranged from 0.059 to 0.216 cm" day for different soil...

in this study, hydrus2d/3d software was used to estimate the hydraulic parameters of van genuchten-mualem model via inverse modeling using double-ring infiltrometers data in 3 different soil textures. nine scenarios of inverse modeling (divided in three groups) were considered with different number (5, 4 and 3) of fitted hydraulic parameters for optimization. in the first group, simulation was ...

a r t i c l e i n f o Lamellae are thin, often discontinuous layers of clay-enriched material that are associated with iron oxides and may occur in Alfisols, Ultisols, Mollisols, Entisols, Inceptisols, or Spodosols. Our analysis of the SSURGO database revealed that there are 118 soil series with lamellae that represent six orders, 14 suborders, and 25 great groups, and 25 subgroups. In Soil Tax...

The current study includes determination of the concentrations lead (Pb) in 18 specimen Kirkuk city soil (K). Inductively Coupled Plasma - Mass Spectrometry (ICP-MS) technology has been used analysis samples laboratories Acme company Canada. Results chemical clarified a rise average (26.11 ppm) compared with international (10 and uncontaminated ones (15 ppm), its surface depth (30.2ppm) lower d...

Accurate predictions of the amount and the rate of long- term deformation of reinforced soils under an applied load are important key issue in geotechnical engineering, in which the deformation of soil develops with time at a state of constant effective stress. Since geosynthetic is generally considered creep sensitive therefore, evaluation of creep behavior of geosynthetic reinforced soil (GRS...
