Phosphorus fractions in apple orchards in southern Brazil
(2017) [Artigo de periódico]Phosphorus (P) applications at dosages higher than the necessary may cause P buildup in the soil labile fractions and, consequently, pollution of water sources. This study aimed to assess accumulation of P fractions as ... -
Remaining phosphorus content to determine phosphorus availability of the soils in Rio Grande do Sul
(2017) [Artigo de periódico]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 ... -
Sorção de fósforo em função do teor inicial e de sistemas de manejo de solos
(2003) [Artigo de periódico]A relação entre o P sorvido/P solução do solo pode ser influenciada pelo teor de P previamente sorvido e pelos sistemas de manejo. Este trabalho teve o objetivo de avaliar as modificações na capacidade de sorção máxima ... -
Substitution of clay content for P-remaining as an index of the phosphorus buffering capacity for soils of Rio Grande do Sul
(2016) [Artigo de periódico]Mehlich-1 soil extract is currently used in Rio Grande do Sul (RS) and Santa Catarina (SC) States, in Brazil, to evaluate soil phosphorus available to plants and Mehlich-1 is sensitive to soil buffering capacity. This ...
