Assessing Organic Phosphorus Contributions for Predicting Soybean Response to Fertilization
(Soil Science Society of America, 2016-08)
The use of organic P fraction in soil test P for soybean [Glycine max (L.) Merr.] under no-till could improve the accuracy to predict crops response to P fertilization. The research objectives were to assess the contribution ...
Soil phosphorus extracted by Bray 1 and Mehlich 3 soil tests as affected by the soil/solution ratio in Mollisols
(Taylor, 2011-01)
Different relationships between soil-test methods results have been reported in several agricultural regions. Differences in the same soil-test procedure (e.g., soil/solution ratio) exist between soil-testing laboratories ...
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 ...
Evaluación de dos métodos para la determinación de fósforo asimilable en suelo de tipo andisol
(Escuela Superior Politécnica de Chimborazo, 2022-04-20)
The current research evaluated the effectiveness of a method for the estimation of assimilable phosphorus in andisol samples from Cebadas River microbasin belonging to the Development for the Environment and Climate Change ...
Is the lack of response of maize to fertilization in soils with low Bray1-p related to labile organic phosphorus?
(Springer, 2021-01-07)
The usual soil test phosphorus (P) neglects the P supply from labile organic P (Po) fractions, which could explain the nonresponse of maize (Zea mays L.) in sites with soil P testing below the critical level. We aim to ...
Phosphorus availability in soils, determined by different extracting procedures
(Empresa Brasil Pesq AgropecBrasiliaBrasil, 1999)
Predicting soil test phosphorus decrease in non-P-fertilized conditions
(Wiley Blackwell Publishing, Inc, 2020-02)
Monitoring the availability of phosphorus (P) in soil under continuous cropping facilitates finding deficiency in crops and contributes to improving crop growth and nutrient management models. Soil P availability for crops ...
Métodos agronómicos y ambientales de determinación de fósforo en argiudoles del sudeste bonaerense = Agronomic and environmental phosphorus determinations in argiudolls of southeast of Buenos Aires
(2015-03-25)
Los análisis de suelo son herramientas útiles para evaluar la fertilidad edáfica y efectuar recomendaciones de fertilización (métodos
agronómicos). Otros métodos, denominados ambientales, estiman el fósforo (P) que puede ...
Availability of a soluble phosphorus source applied to soil samples with different acidicity levels
(Revista Brasileira de Ciência do Solo, 2017)
Is the Lack of Response of Maize to Fertilization in Soils with Low Bray1-P Related to Labile Organic Phosphorus?
(Sociedad Chilena de la Ciencia del Suelo, 2021-01)
The usual soil test phosphorus (P) neglects the P supply from labile organic P (Po) fractions, which could explain the nonresponse of maize (Zea mays L.) in sites with soil P testing below the critical level. We aim to ...
