Autoradiography of Pi Distribution in Barley Seedlings

open access: yesBio-Protocol, 2014
Phosphorus-32 and Phosphorus-33 are radioisotopes of phosphorus. These isotopes are used to trace ionic phosphorus and phosphorus compounds. This protocol is used to follow the movement of inorganic phosphate (PO43-) from a leaf tip to the rest of the ...

The molecular basis of phosphite and hypophosphite recognition by ABC-transporters

open access: yesNature Communications, 2017
Some bacteria can use inorganic phosphite and hypophosphite as sources of inorganic phosphorus. Here, the authors report crystal structures of the periplasmic proteins that bind these reduced phosphorus species and show that a P-H…π interaction between ...

EFFECT OF ORGANIC AND INORGANIC PHOSPHORUS APPLICATION ON SOME CHEMICAL PROPERTIES AND SOIL PHOSPHORUS FRACTIONS [PDF]

open access: yesJournal of Soil Sciences and Agricultural Engineering, 2009
Two successive cultivation seasons (winter season 2006/2007 and summer season 2007) were conducted in field experiments on silty clay loam soil at El-Gemmeiza Agricultural Research Station, El-Gharbia Governorate.

Ecological role of surface phosphatase activities of Rivulariaceae [PDF]

open access: yes, 1996
The literature suggests that the cyanobacterium Rivularia is found at sites where organic phosphorus (P), at times forms a high proportion of total P in the environment.

Effects of goat manure and inorganic phosphate addition on soil inorganic and microbial biomass phosphorus fractions under laboratory incubation conditions

open access: yes, 2009
Changes in inorganic phosphorus (P) and soil microbial biomass P following the addition of goat manure and different amounts of inorganic P to an Umbric Ferralsol were assessed over 12 weeks under laboratory incubation conditions using a sequential ...

DESEMPENHO E AVALIAÇÃO DA CARCAÇA EM SUÍNOS ALIMENTADOS COM RAÇÕES DE TERMINAÇÃO COM FITASE ASSOCIADA À RETIRADA DE MICROMINERAIS, VITAMINAS E FÓSFORO INORGÂNICO

open access: yesCiência Animal Brasileira, 2010
The experiment aimed to evaluate the effect of phytase enzyme in rations for swine at the finishing phase without the use of mineral-vitamin supplement and with reduced levels of inorganic phosphorus on performance and carcass characteristics, ashes and ...

Effect of Sterilization on the Change of Available Phosphorus During the Wetting and Drying Process [PDF]

open access: yesE3S Web of Conferences
Wetting and drying are typical natural events in arid and semiarid areas. In order to explore the contribution of microorganisms to the change in soil phosphorus components during wetting and drying processes, soil incubation experiments were conducted ...

Diversity in expression of phosphorus (P) responsive genes in Cucumis Melo L. [PDF]

open access: yes, 2012
Phosphorus (P) is a major limiting nutrient for plant growth in many soils. Studies in model species have identified genes involved in plant adaptations to low soil P availability.

Phosphorus fractionation and distribution in Nitisols of the central Ethiopian highlands affects soil nutrient management strategies in barley (Hordeum vulgare L.) production [PDF]

open access: yesPeerJ
Optimizing nutrient management is essential for sustaining crop productivity on fertilizer-unresponsive acidic soils, particularly through a comprehensive understanding of soil phosphorus (P) dynamics.

Availability for plants of phosphorus in some virgin peat samples

open access: yesAgricultural and Food Science, 1958
The availability to plants of native peat phosphorus was studied by chemical methods and by a pot experiment in which three successive oat crops were grown with peat as the only source of phosphorus.
