Development of an alternative to the olsen test for determining corn plant-available phosphorus in calcareous soils
نویسندگان
چکیده مقاله:
In this research, several chemical extractants and modified Olsen methods were studied in 25 surface-calcareous soils (0-30 cm) for determining available phosphorus (P) for corn (Zea mays L.) plant. In this experiment, the highest correlation was obtained between extracted P by Olsen and Colwell methods (NaHCO3-extractable P) and dry weight of corn shoot (r =0.67 and 0.75, p

abstract in this study, p critical level for corn plant (zea mays l.) was determined using pbc in 25 combined soils samples from different fields of east azerbaijan province. to calculate the pbc, current soil p test methods such olsen,colwel, soltanpur and schowab, kelna2 and iron impregnated strips as a quantity factor (q) and the methods of soluble p measurements such as distilled water, cal...
متن کاملdevelopment and implementation of an optimized control strategy for induction machine in an electric vehicle
in the area of automotive engineering there is a tendency to more electrification of power train. in this work control of an induction machine for the application of electric vehicle is investigated. through the changing operating point of the machine, adapting the rotor magnetization current seems to be useful to increase the machines efficiency. in the literature there are many approaches wh...
15 صفحه اولRelationship of soil test phosphorus and sampling depth to runoff phosphorus in calcareous and noncalcareous soils.
A study was initiated to investigate the relationship between soil test P and depth of soil sampling with runoff losses of dissolved molybdate reactive phosphorus (DMRP). Rainfall simulations were conducted on two noncalcareous soils, a Windthorst sandy loam (fine, mixed, thermic Udic Paleustalf) and a Blanket clay loam (fine, mixed, thermic Pachic Argiustoll), and two calcareous soils, a Purve...
متن کاملComparison of Al P and Olsen P Test in Calcareous Soils in Croatia
The common use of soil-fertility control data in Croatia includes properties such as soil pH, organic matter content and plant-available phosphorus (P) and potassium (K) extracted by ammonium lactate (AL) solution. These data are commonly used for fertilizer recommendations for both field vegetable (Lončarić et al., 2003) and arable crops (Vukadinović et al., 1996). Also, the same soil data hav...
متن کاملtemporal changes in available phosphorus in some calcareous soils
application of phosphorus (p) fertilizers as solid or liquid fertilizers to soils leads to re-actions of orthophosphate ions with various soil components which remove p from the so-lution phase and convert it to less soluble phosphates. this study was aimed at determin-ing soil properties that affect the rate of phosphate retention in 28 contrasting calcareous soils from different geographical ...
