Fósforo disponível determinado por lâmina de resina enterrada Soil phosphorus availability determined by anionic-exchange resin membrane in the soil

Revista Brasileira de Ciência do Solo, 2009
O uso de lâminas de resina de troca aniônica enterradas no solo permite simular, em parte, o comportamento das raízes das plantas em relação à absorção de P. Essa técnica, utilizada diretamente no solo nas mesmas condições que se cultivam as plantas, sem

Does rotational bale grazing affect the distribution of soil nutrients across pastures?

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Rotational bale grazing (RBG), the strategic feeding of round hay bales directly on pasture with controlled access, offers an alternative to continuous winter hay feeding in a single paddock. This study evaluated RBG's potential to redistribute nutrients by increasing soil concentrations in field areas with lower phosphorus (P) and potassium ...

Do we properly quantify P from Mehlich 1 or Mehlich 3 extracting solutions?

, 2022
Abstract Aims The performance of colorimetric methods for P quantification is usually overlooked by researchers and not suitable to errors. Here, we investigated the performance of two blue colorimetric methods for P quantification, Braga & Defelipo (1974) (B&D) and Murphy & Riley (1962) (M&R), using two commonly soil P ...

Comparing the effects of soil test interpretations for P and K on a creeping bentgrass putting green

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Soil testing provides golf course superintendents with the information needed to apply fertilizers at optimal rates, thereby avoiding nutrient deficiencies and unnecessary applications. However, nutrient rate recommendations vary depending on how soil test results are interpreted.

Effects of Potassium Source and Secondary Nutrients on Potato Yield and Quality in Southcentral Alaska. [PDF]

, 1990
Calcium (Ca), magnesium (Mg), and sulfur (S) are required for the growth and development of all higher plants. They are commonly referred to as secondary nutrients because they are less often limiting to plant growth than the primary nutrients nitrogen ...

Soil properties and pH of the extractors influence extraction and availability P in alkaline soils from the São Francisco Valley, Brazil

Revista Brasileira de Ciência do Solo
Phosphorus (P) is one of the most used nutrients in agriculture due to its high degree of interaction with the soil. It is susceptible to calcium precipitation in poorly weathered and alkaline soils, such as those in the Brazilian Semi-Arid region ...

Should cotton growers apply full nitrogen rate when using broiler‐litter as soil amendment?

Crop, Forage &Turfgrass Management, Volume 12, Issue 1, June 2026.
Abstract Nitrogen plays a critical role in cotton (Gossypium hirsutum L.) production. Interest in using broiler (Gallus gallus domesticus) litter has increased in recent years due to its nutrient and soil health benefits. However, growers typically do not discount the N present in broiler litter and apply a full dose of fertilizer N.
