Aislamiento y caracterización bioquímica de metabolitos producidos por rizobacterias que solubilizan fosfato.
Provedor de dados: 32
Autores: Paredes Mendoza, Marianela.
El empleo de bacterias solubilizadoras de fosfato (BSP) para la solubilización de distintas rocas fosfatadas y de otras fuentes de fósforo es una alternativa para incrementar la cantidad de P disponible para las plantas. Se aislaron 147 BSP de la raíz y rizoplano  de diferentes  plantas cultivadas.  El  medio de cultivo  denominado Medio Mínimo para Solubilización de Fosfato Colegio de Postgraduados con MgCl (MMSFCP-Mg) fue el más eficiente,  debido a que en medio sólido se observaron halos de solubilización de hasta 3.8 cm a los  catorce días, y en medio líquido se determinaron hasta   380 mg mL-1  de fosfato soluble a los seis días.   Veintisiete  de las mejores cepas     fueron seleccionadas  con base  en la eficiencia de solubilización de fosfato...

EFFECTIVENESS OF THE APPLICATION OF ARBUSCULAR MYCORRHIZA FUNGI AND ORGANIC AMENDMENTS TO IMPROVE SOIL QUALITY AND PLANT PERFORMANCE UNDER STRESS CONDITIONS
Provedor de dados: 126
Autores: Medina,Almudena; Azcón,Rosario.
Plant growth is limited in arid and/or contaminated sites due to the adverse conditions coming from heavy metal (HM) contamination and/or water stress. Moreover, soils from these areas are generally characterised by poor soil structure, low water-holding capacity, lack of organic matter and nutrient deficiency. In order to carry out a successful re-afforestation, it is necessary to improve soil quality and the ability of plants species to resist this harsh environment. The symbiosis with arbuscular mycorrhizal (AM) fungi has been proposed as one of the mechanisms of plant heavy metal tolerance and water stress avoidance. On the other hand, addition of organic amendments to the soil can reverse degradation of soil properties. Agro-waste residues such as dry...

Gafsa rock phosphate and triple superphosphate for dry matter production and P uptake by corn
Provedor de dados: 63
Autores: Corrêa,Rossini Mattos; Nascimento,Clístenes Williams Araújo do; Souza,Silvana Keely de Sá; Freire,Fernando José; Silva,Gleibson Barbosa da.
Crops in general make poor use of phosphorous fertilizer and, as a result, recommended rates and production costs are very high. Phosphorus can be made more readily available to plants by proper management of phosphate fertilization, selecting both, type of fertilizer and application method. This study was carried out to evaluate the efficiency of the natural Gafsa rock phosphate and the triple superphosphate on dry matter production and P uptake by corn plants cultivated in a greenhouse. Fertilizers were applied localized and broadcast/incorporated on to two soils with contrasting phosphorus capacity factors (PCF). Rock phosphate broadcast application was as efficient as triple superphosphate in increasing corn plant dry matter in the Tropudult, with...

Non-conventional P sources for zebu cows in Brazil
Provedor de dados: 63
Autores: Vitti,D.M.S.S.; Abdalla,A.L.; Lopes,H.O.S.; Pereira,E.A.; Meirelles,C.F.
To evaluate non-conventional phosphorus sources, a group of 400 Nellore cows mantained under pasture received a mineral mixture with different P sources (group I: superphosphate - 500 ppm P; group II: superphosphate - 340 ppm P plus rock phosphate Patos 160 ppm P; group III: superphosphate 340 ppm P plus dicalcium phosphate 160 ppm P; group IV - dicalcium phosphate 500 ppm P). There were no differences in pregnancy rate, calving rate and calving interval. A fluorine deposition in bone was observed for the treatments with superphosphate and rock phosphate (66.92 ± 15.53; 69.97 ± 6.5 and 64.05 ± 3.35% respectively for group I, II and III). Superphosphate was almost as good dicalcium phosphate to provide phosphorus for grazing cows and there was a potentially...

Rhizosphere pH and phosphorus forms in an Oxisol cultivated with soybean, brachiaria grass, millet and sorghum
Provedor de dados: 63
Autores: Schoninger,Evandro Luiz; Gatiboni,Luciano Colpo; Ernani,Paulo Roberto.
Plants have shown different responses to fertilization with rock phosphate, including responses through alteration of the attributes of rhizospheric soil. The objective of this study was to evaluate soil pH alterations and alterations in the contents of forms of phosphorus in the rhizosphere of soil fertilized with rock phosphate as a result of cultivation of species of plants. An experiment was developed under greenhouse conditions to evaluate alterations in the pH and in the forms of phosphorus in the rhizosphere of an Oxisol fertilized with rock phosphate and cultivated with four species. Treatments consisted of the cultivation of four species of soybean - Glycine max (L.) Merrill, brachiaria grass - Brachiaria brizantha Hochst Stapf, millet -...

Study on the response of rice, RD. 43 variety, grown on Ongkharak soil with residual lime to rates of phosphate calculated from P adsorption characteristics such as P adsorption capacity with the value of 802 mgP kg-1 (Pmax), half of Pmax (401 mg P kg-1), 0.2 mg P L-1 (398 mg P kg-1) and the rate of 157 mg P kg-1 recommended by DOA and to different types of phosphate fertilizer, including tripple super phosphate and rock phosphate was conducted. Fifteen days old rice seedling was transplanted in pot under greenhouse cover. Urea and KCl at the rates of 504 and 260 mg kg-1 were used as top dressing for all treatments and the former at the rate of 98 mg kg-1 was applied at flowering stage. Results revealed that using of TSP as well as applying P at the rate...
