Research ArticleOpen accessAll words, across the recordEvaluation of Leaf Total Nitrogen Content for Nitrogen Management in a Malaysian Paddy Field by Using Soil Plant Analysis Development Chlorophyll MeterA. Gholizadeh, M. S. M. Amin, A. R. Anuar, W. AimrunProblem statement: Laboratory plant testing is usually time-consuming and high-costing. Hence, plant nutrient variability must be measured rapidly and the information made known to the farmers before the new season starts. Site-specific crop management, well-established in some developed countries, is now being considered in other places such as Malaysia. Approach: The application of site-specific management principles and techniques to diverse … …American Journal of Agricultural and Biological Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 9,238 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordThe Effects of Seasonal Variations on Typha capensis and Heliconia psittacorum in the Remediation of Heavy Metals from Soil and WaterWiafe Samuel, Buamah Richard, Owusu MichaelDifferent plant species have been used in the remediation of different heavy metals. The performance of a macrophyte to remediate heavy metals may be dependent on a lot of factors which may include water chemistry, metal solubilityand temperature. The objective of this research was to ascertain the effects of seasonal variations on the remediation of heavy metals. To this end,two … …American Journal of Applied Sciences, Vol. 15, Issue 12 · 31 Jan 2019 · 7,787 accessesView PDF Cite

Research ArticleOpen accessAll words, across the recordOpen ended-coaxial Cable Measurements of Saturated Sandy SoilsAlberto GodioThe application of electromagnetic methods in the radar and micro-wave frequency band allows the fluid content of soils to be estimated; the heuristic or physically-based models permit to relate the observed electrical permittivity of the soils with the porosity and fluid saturation. The role of the effect of the free water and bound water in the overall electromagnetic behaviour of … …American Journal of Environmental Sciences, Vol. 3, Issue 3 · 30 Sep 2007 · 6,800 accessesView PDF Cite
