Release potential of phosphorus in Florida sandy soils in relation to phosphorus fractions and adsorption capacity.
Information on P release potential in relation to labile P and P fractions in sandy soils is limited. In this study, P release potential was determined by leaching, and labile P, soil P fractionation, and P adsorption capacity were measured in the laboratory using 96 Florida sandy soil samples to evaluate the relationship between P release in water and soil P status. The sandy soils had a very ...
متن کاملPhosphorus Inflow into Two Species of Clover Root with Different Morphology Colonized by AM Fungi
The effects of arbuscular mycorrhizal (AM) fungi on growth and phosphorus (P) inflow into two species of clover plant with different root morphology were studied. The experiment was arranged as a randomized complete block design consisting of a 2×3×3 factorial combination of two clover species (Trifolium alexandrinum L. and Trifolium pratense L.), three mycorrhiza states (without mycorrhiza, Gl...
متن کاملOrganic Phosphorus Composition and Potential Bioavailability in Semi-Arid Arable Soils of the Western United States
the need to understand the nature of organic P in these soils. The organic P composition of semi-arid arable soils is largely unSoil organic P determination has traditionally been known, but such information is fundamental to understanding P dynamics in irrigated agriculture. We used solution 31P nuclear magnetic hampered by difficulties with the extraction, separation resonance (NMR) spectrosc...

نتایج این مطالعه نشان می دهد که مقدار کلسیم (یونیزه و تام)، منیزیم و فسفر به طور معنی داری تغییر پیدا کرد به جزء مقدار کلسیم تام و منیزیم در روش داخل عضلانی که تغییر معنی داری نداشته است. بر اساس نتایج این مطالعه می توان نتیجه گیری کرد که اکسی تتراساکلین بر روی مقادیر سرمی کلسیم و منیزیم تأثیر می گذارد باید مقدار این کاتیون ها در بیماران، در هنگامی که اکسی تتراسایکلین استفاده می شود مورد توجه ق...
