Phosphorus fractions in Brazilian Cerrado soils as affected by tillage
(Elsevier B.V., 2009-09-01)
No-tillage systems lead to physical, chemical and biological changes in soil. Soil fertility is responsive to changes in tillage as it depends on nutrient status, soil water content and biological characteristics. This ...
Formas de fósforo no solo após o cultivo de braquiária e tremoço branco
(2013-08-01)
Phosphorus is one of the major factor that limits agricultural productivity in most tropical soils. The objective of this study was to assess P transformations and availability in a soil cropped to brachiaria (Urochloa ...
Response of Potato Cultivars to Phosphate Fertilization in Tropical Soils with Different Phosphorus Availabilities
(2016-09-01)
Potato cultivars have different strategies for dealing with phosphorus (P) deficiency in soil, and their response to P fertilization may vary because of differences in soil P availability. This study was performed to ...
TOTAL AND ORGANIC PHOSPHORUS IN CHILEAN VOLCANIC SOILS

Bioavailability of Phosphorus and Micronutrients in the Soil-Plant-Microbe Continuum
(Sociedad Chilena de la Ciencia del Suelo, 2008)
Assessment of phosphorus availability in soil cultivated with ruzigrass
(Elsevier B.V., 2018-02-15)
Growing ruzigrass (Urochloa ruziziensis) in crop rotation systems has been suggested as a strategy to increase soil phosphorus (P) cycling and P availability. However, despite increased P lability shown in routine soil ...
Stability and phosphorus leaching of tilapia feed in water
(Univ Federal Santa Maria, 2019-01-01)
The present research aimed to investigate the stability of pellets and phosphorus leaching of diets formulated for juveniles of Nile tilapia (Oreochromis niloticus), with different sources of phosphorus and different ...
Phosphorus Budget in Integrated Multitrophic Aquaculture Systems with Nile Tilapia, Oreochromis niloticus, and Amazon River Prawn, Macrobrachium amazonicum
(2017-06-01)
Integrated multitrophic aquaculture (IMTA) systems are designed mainly for efficient use of resources. Substrates added to aquaculture ponds provide space for periphyton to settle and recover nutrients, making these nutrients ...
