Revised Iowa P and K Recommendations: New Soil-test K Interpretations and Support for a New Soil P Test
The Iowa soil-test interpretations and fertilizer recommendations for phosphorus (P) and potassium (K) were last updated in 1996 and 1999. The 1996 update involved the most important changes compared with previous recommendations. New soil-test P and K interpretation classes (very low, low, optimum, high, and very high) were developed to classify soil-test values into two sets corresponding to ...

متن کاملSoft Soil Seismic Design Spectra Including Soil-structure Interaction
Design spectrum is known as an essential tool in earthquake engineering for calculation of maximum (design) responses in a structural system. Soil-structure interaction (SSI), as a phenomenon of coupling of responses of a structure and its underlying soil, was explored after introduction of design spectra and has not been taken into account in developing a design spectrum traditionally. To cons...
متن کاملOptimum driving a Z-pinch for soft X-Ray lasers
A capillary plasma z-pinch as an alternative active medium of soft X-Ray lasers was studied experimentally and theoretically. The theoretical analysis was based on the self consistent solution of the so called “snow plow” model. The dynamics of pinched plasma is determined by the capillary parameters and by the time dependence of electrical current passing through it. The current time dependenc...
متن کاملInvestigation of Soil Amplification in North Cyprus
In this study, soil characteristics were investigated using four well-located earthquakes recorded by six accelerometers located in North Cyprus. The amplification values obtained according to the soil features were mapped in accordance with different frequencies using horizontal to vertical spectral ratio method. The dominant period values of the units below the station locations were calculat...
