Assessing soil P fractions changes with long‐term phosphorus fertilization related to crop yield of soybean and maize
(Wiley, 2020-02)
Long-term P fertilization increases soil phosphorus (P) labile fractions, which can be associated with crop P uptake and grain yield and are useful to improve fertilizer recommendations. Research aims were to evaluate in ...
Yield, quality and foliar nutrient concentration of 'Orlando' tangelo under different fertilizer regimesProducción, calidad y concentración foliar de nutrimentos del tangelo 'Orlando' bajo distintos niveles de abonamiento

Phosphorus fertilization of a grass-legume mixture: effect on plant growth, nutrients acquisition and symbiotic associations with soil microorganisms
(2015-09)
Adding P on Lotus tenuis and Festuca arundinacea, pure or mixed, on growth, nitrogen (N) and phosphorus (P) acquisition and associations with soil microorganisms was studied to investigate the establishment of Lotus for ...
Responses of C3 and C4 grasses to application of nitrogen and phosphorus fertilizer at two dates in the spring
(Wiley Blackwell Publishing, Inc, 2010-03)
In grasslands composed of C3 and C4 plants, a different pattern of response by the two photosynthetic types to fertilizer may change the floristic composition of the community. In this study, we evaluated the effects of ...
Long-term phosphorus fertilization of wheat, soybean and maize on Mollisols: Soil test trends, critical levels and balances
(Elsevier Science, 2018-05)
Few reports have compared the P critical level between different crops under equivalent growing conditions and the impact of P balance and P fertilization practices on the long term dynamics of soil available P. The ...

Dry weight partitioning and hydraulic traits in young Pinus taeda trees fertilized with nitrogen and phosphorus in a subtropical area
(2013-03)
Plants of Pinus taeda L. from each of four families were fertilized with nitrogen (N), phosphorus (P) or N + P at planting. The H family had the highest growth in dry mass while the L family had the lowest growth. Measurements ...
