The aim of this study was to verify the effect of different substrates, in the presence and absence of controlled-release fertiliser, on the growth and morphological quality of seedlings of Agonandra brasiliensis Miers ex Benth. & Hook.f., in the state of Roraima, Brazil. The experimental design was a 2 x 5 factorial scheme, with and without the addition of 1.0 g L-1 NPK 18-05-09 formulation controlled-release encapsulated fertiliser (Forth Cote®) and five substrates. The following were evaluated: shoot height (H), collar diameter (CD), increase in shoot length (IncH) and collar diameter (IncCD), shoot dry weight (SDW), root dry weight (RDW), total dry weight (TDW) and Dickson quality index (DQI). The use of NPK 18-05-09 formulation controlled-release fertiliser (Forth Cote®) in a medium-sand substrate is recommended for obtaining plants of Agonandra brasiliensis of greater robustness, balance of biomass distribution, and a high standard of quality. In the substrate composed of soil from the cerrado + carbonised rice husks - CRH + organic substrate (2:1:1), the addition of NPK 18-05-09 formulation Forth Cote® is not necessary to obtain Agonandra brasiliensis plants of good morphological quality. Substrate 3, composed of soil + CRH (3:1), with or without the addition of NPK 18-05-09 formulation Forth Cote®, is not recommended for producing plants of Agonandra brasiliensis, due to the slow development and reduced morphological quality of the plants. |

The objective of this work was to evaluate remaining P compared with soil clay content as a P buffer index to classify P extracted by the Mehlich-1 (M1) and Mehlich-3 (M3) methods in soils from the state of Rio Grande do Sul, Brazil. The experiment was carried out in a completely randomized design with five P2O5 rates (0, 50, 100, 200, and 400 mg kg-1) and two sucessive corn crops, and three replicates, in 20 representative soils of the state. P extracted by M1 and M3 before crop planting was adjusted to P contents in biomass, considering soil buffer capacity. The division of soils into different buffering classes, based on soil clay or remaining P, improved the capacity of estimating soil available P of both methods. However, there was no difference among the correlation coefficients obtained by classifying soils according to the evaluated indexes (remaining P or soil clay) for both M1 and M3 methods. Remaining P is a viable alternative to replace soil clay content to classify soil P extracted with the M1 and M3 methods. |
