In 1924, Haldane, Wigglesworth, and Wood-row reported on the effect of reaction changes on human inorganic metabolism (1). They found that respiratory alkalosis caused a sharp fall and respiratory acidosis a sharp rise in serum phosphorus concentration. They also examined metabolic changes induced by oral ingestion of Na-HCO3 or NH4Cl for several days, but respiratory compensation would have mi...

this research was carried out at agricultural and natural resources research center, isfahan, islamic republic of iran (kabootar abad) for two years (2006-2007). the experiment was conducted as a split plot arranged in randomized block design with four replications. treatments were four levels of n fertilizer [110, (160 = soil and water research institute recommendation), 210 and 260 kg ha-1] a...

BACKGROUND: One of limitation factor in agricultural plants production in dry areas, supply requires water. Also nutrition crop management is a necessary strategy for achieve sustainable agriculture. OBJECTIVES: Current study was conducted to assessment the effects of different irrigation regimes and several amount of nitrogen fertilizer on seed nutrition...

Phosphorus concentration in the soil solution of agricultural soils should be a consensus of the agronomic and environmental aspect. Data from literary sources are inconsistent if the method of soil solution extraction from the soil and the method of phosphorus detection are not indicated. In the present paper a simplified procedure of soil solution extraction is used that is derived from the n...

Musilova A., Lichovnikova M., Kupcikova L., Anderle V. (2017): Effect of suboptimal levels of non-phytate phosphorus and exogenous phytase on precaecal digestibility of phosphorus and calcium in laying hens. Czech J. Anim. Sci., 62, 473–481. The precaecal digestibility of phosphorus and calcium in laying hens was evaluated at two dietary levels of non-phytate phosphorus (NPP; 1.58 and 2.03 g/kg...

Grid-oriented, physically based catchment models calculate fields of various hydrological variables relevant to phosphorus detachment and transport. These include (i) for surface transport: overland flow depth and flow in the coordinate directions, sediment load, and sediment concentration and (ii) for subsurface transport: soil moisture and hydraulic head at various depths in the soil. These v...

Phosphorus is known to be exported from leaves of apple (8, 9, 10), bean (4, 6, 11, 12, 13), chrysanthemum (1, 2), corn (11, 12), tomato (12) and squash (71). The present work with bean plants compares export following application by spray, leaf vein injection (4) and droplet (13) methods. Other factors investigated which affect absorption and subsequent translocation of the spray-applied phosp...

A field experiment was conducted at the Instructional farm, Rajasthan College of Agriculture, Udaipur for two years (2017–18 and 2018–19) during winter (rabi) season. The experiments were arranged in a randomized block design (RBD) manner with 3 replications. results showed that, seed inoculation biofertilizers (Azotobacter + Phosphorus solubilizing bacteria Potash mobilizing Zinc bacteria) imp...
