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 ...
Cover Crops and Soil Phosphorus Availability
(Taylor & Francis Inc, 2017-01-01)
Plants affect soil phosphorus (P) solubility through root exudates, but studies are lacking on species used as relay or cover crops in tropical environments. We evaluated the effect of cover crops on soil phosphorus (P) ...
Adsorption and desorption kinetics and phosphorus hysteresis in highly weathered soil by stirred flow chamber experiments
(Soil and Tillage Research, 2018)
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 ...
Phosphorus fractions as a function of the use of phosphate fertilizers in different soil classesFrações de fósforo em função do uso de fertilizantes fosfatados em distintas classes de solo
(2021-08-05)
Most Brazilian soils have low natural fertility. The main characteristic is phosphorus (P) deficiency and high P adsorption capacity. This creates the need to add phosphate mineral fertilizers, organic or organomineral. ...
Environmental risk of increasing phosphorus addition in relation to soil sorption capacity
(Elsevier Science, 2007-12)
Phosphorus content of soil profiles, interstitial water, and shallow groundwater was determined in a semiurban region of Buenos Aires city in order to examine phosphorus leaching. Soils from different places and position ...
PHOSPHORUS AVAILABILITY IN OXIDIC SOILS TREATED WITH LIME AND SILICATE APPLICATIONS
(Soc Brasileira De Ciencia Do Solo, 2014-07-01)
Based on the assumption that silicate application can raise soil P availability for crops, the aim of this research was to compare the effect of silicate application on soil P desorption with that of liming, in evaluations ...
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 ...
Evaluation of coal as adsorbent for phosphate removal
(Springer HeidelbergHeidelbergAlemanha, 2013)
