Ahmed F. (2014) Evaluation of Available Phosphorus by Soil Test Methods in an Acidic Soil Incubated with Different Levels of Lime and Phosphorus. Open Journal of Soil Science, 4(3): 103-108.SARKER, A., MD ABUL KASHEM, KHAN TOWHID OSMAN, IMAM HOSSAIN & AHMED., F. 2014. Evaluation of ...
Optimizing phosphorus (P) application to agricultural soils is fundamental to crop production and water quality protection. We sought to relate soil P tests and P sorption characteristics to both crop yield response to P application and environmentally critical soil P status. Barley (Hordeum vulgare ...
In this study, the method of measuring concentrations of available phosphorus in soil was developed. The sample volume was 2.50 g and sodium bicarbonate solution was 50 ml. The detection limit of this method was 0.4 mg/kg and lower limit was 1.6 mg / kg when 1 cm cuvette was used. Key...

KYUMA,Kazutake - 《Soil Science & Plant Nutrition》 被引量: 22发表: 1973年 Comparison of several methods for the determination of available phosphorus in the soils for corn and rice In order to refine the chemical potentiality component extracted by principal component analysis, the method of fa...
TRANSFORMATIONS OF ORGANIC PHOSPHORUS SUBSTRATES IN SOILS AS EVALUATED BY NaHCO3 EXTRACTION. The sodium-bicarbonate (NaHCO3) method of Olsen et al. was primarily designed to extract inorganic P (P1) and to correlate this P-pool with plant response... RA Bowman,CV Cole - 《Soil Science》 被...
Change of available phosphorus in soil profile of farmland soil (three main paddy soils: White soil, Huangni soil and Wushan soil) during wheat and rice growth was studied in the Taihu Lake region. The results were as follows: available phosphorus in soil profiles was gradually decreased from ...
21 August 2018 Data Descriptor: A global dataset of plant available and unavailable phosphorus in natural soils derived by Hedley method Enqing Hou1,*, Xiang Tan2,*, Marijke Heenan3 & Dazhi Wen1,4 Soil phosphorus (P) fractions are critical for understanding soil P dynamics and availability. ...
【Objective】 In order to reveal the impact of various fertilization treatments on the characteristics of paddy soil phosphorus(P) evolution, and its response to soil P balance. We analyzed the annual variation of soil available P content, total P content, soil P balance, and phosphorus activatio...
