Potassium fixation is one of the most important factors influencing the availability of this ion for plants. This research was carried out to evaluate the relationship between potassium (K) fixation with some physical and chemical characteristics of soils and clay minerals and to investigate the effect of the dry and wet cycle on potassium fixation in Kakan Plain, in Kohgilouye & Boyerahmad Pro...
Bacillus velezensis strain S141 is a plant growth-promoting rhizobacterium isolated from soybean (Glycine max) rhizosphere that enhances soybean growth, nodulation, and N2 fixation efficiency by coinoculation with Bradyrhizobium diazoefficiens USDA110. The S141 genome was identified to comprise a 3,974,582-bp-long circular DNA sequence encoding at least 3,817 proteins.
Phosphorus (P) and nitrogen (N) are the most essential nutrients for plant growth. Deficiency of these elements causes a considerable loss of crop yield. Nowadays, using of biofertilizers in cultivation of strategic crops, such as greenhouse crops, is very important because of resolving the P and N deficiency. This research was carried out to evaluate the potential of rhizobacteria of valerian ...
Sugarcane (Saccharum officinarum L.) and rotational crops have been cultivated without potassium fertilizers for many years in southwestern Iran. Although potassium was removed from this soil, no response has been reported to K fertilizers by crops. This study was conducted to evaluate the effects of wetting and drying, and cultivation systems on potassium fixation in some Khouzestan soils. Th...
Potassium fixation and release by phillosilicate clay minerals in soils are very important processes influencing the availability of K to plants. This investigation was conducted to determine the potassium fixation capacity and charge characteristics of soil clays of 15 surface soils (0-30 cm) from central and northern Iran. After clay particle separation, both total and tetrahedral cation exch...
Background: Conventional fixation methods of posterior wall acetabular fractures feature the use of plating and lagscrews. However, fixation of posterior wall fractures with buttress plating alone offers potential advantages by avoidingthe hardware complications related to hardware placement through the wall fragment. The purpose of this study wasto examine if buttress plating...
The level of complications after treatment patients with bone fractures stays high 22–60 %. Understanding ankle-foot joint biomechanics is critical for choosing trendy methods hybrid fixation or the traditional fibula plate and positional screw distal syndesmosis. Objective. To analyze effectiveness surgical unstable trans- suprasyndesmosis stable-elastic (HSEF) in comparison method a positioni...
conclusions in this case series study, the fixation of different types of tibial plateau fractures with 3.5 mm simple non-locking and non-precontoured plates was associated with acceptable clinical, functional, and radiographic outcomes. based on the advantages and costs of these plates, the authors recommend using 3.5 mm simple plates for different types of tibial plateau fractures. results th...
there have been a number of developments in screw design and implantation techniques over recent years, including proposal of an alternative trajectory entitled as cortical bone trajectory (cbt). cortical bone trajectory has been investigated in recent medical treatments as an alternative for screw fixation aimed at increasing purchase of pedicle screws in higher density bone. cbt screw inserti...
