Gafsa rock phosphate and triple superphosphate for dry matter production and P uptake by corn Fosfato de Gafsa e superfosfato triplo na produção de matéria seca e absorção de fósforo pelo milho

Scientia Agricola, 2005
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

Phosphorus Dynamics and Impacts on Potato Production in Northeast Florida

EDIS, 2023
Florida is one of two states (FL and CA) that produce spring potatoes, FL having the highest crop value out of any state in the country ($469.67 per ton). Due to the low phosphorus use efficiency (PUE), high rates of phosphorus (P) are applied to ensure

The role of microorganisms in mobilization and fixation of phosphorus in sediments [PDF]

Hydrobiologia, 1993
Cycling of phosphorus (P) at the sediment/water interface is generally considered to be an abiotic process. Sediment bacteria are assumed to play only an indirect role by accelerating the transfer of electron from electron donors to electron acceptors, thus providing the necessary conditions for redoxand pH-dependent, abiotic sorption/desorption or ...

Impact of Phosphorus Fertilization on Leaching, Accumulation, and Microbial Cycling in New Apple Orchards

Agronomy
Field experiments spanning five years were conducted to convert barren mountainous land into apple orchards, testing five phosphorus (P) fertilization schemes: no inorganic P (NP0K), superphosphate (FP), water-soluble inorganic P (WSF), superphosphate ...

Phosphorus Transformation in Soils Following Co-Application of Charcoal and Wood Ash

Agronomy, 2021
Phosphorus (P) is a vital soil macronutrient required by plants for optimum growth and development. However, its availability is limited because of fixation. The phosphorus fixation reaction is pH dependent.

Contrasting Expression of Rhizobial Phytase in Nodules of Two Soybean Cultivars Grown Under Low Phosphorus Availability

Frontiers in Sustainable Food Systems, 2021
Phosphorus deficiency can be a major limitation to legume growth when plant nitrogen nutrition depends on symbiotic nitrogen fixation. One possible approach to overcome this constraint is the selection of plant and rhizobial genotypes capable of ...

Box-modelling of the impacts of atmospheric nitrogen deposition and benthic remineralisation on the nitrogen cycle of the eastern tropical South Pacific [PDF]

Biogeosciences, 2016
Both atmospheric deposition and benthic remineralisation influence the marine nitrogen cycle, and hence ultimately also marine primary production. The biological and biogeochemical relations in the eastern tropical South Pacific (ETSP) among nitrogen ...

Legume-Rhizobium Strain Specificity Enhances Nutrition and Nitrogen Fixation in Faba Bean (Vicia faba L.)

Agronomy, 2020
This study reports the effectiveness of some selected rhizobium strains in enhancing nitrogen fixation and nutrient uptake in Vicia faba L. Multi-location field experiments were conducted for two years (2016 and 2017) using a split-plot in randomized ...

Low levels of ribosomal RNA partly account for the very high photosynthetic phosphorus-use efficiency of Proteaceae species [PDF]

, 2013
Proteaceae species in south-western Australia occur on phosphorus- (P) impoverished soils. Their leaves contain very low P levels, but have relatively high rates of photosynthesis.

Responses of Nitrogen Metabolism Pathways to Low-Phosphorus Stress: Decrease in Nitrogen Accumulation and Alterations in Protein Metabolism in Soybeans

Agronomy
Phosphorus is an indispensable nutrient for nitrogen metabolism in soybeans. In this study, two P levels were established, 1 mg/L (low-P stress) and 31 mg/L (normal P, CK), by combining 15N labeling with real-time quantitative PCR and the UHPLC-MS/MS ...
