Ammonium sulfate enhances the effectiveness of reactive natural phosphate for fertilizing tropical grasses

Tropical Grasslands-Forrajes Tropicales, 2020
Reactive natural phosphate is a slow and gradual solubilizing fertilizer, which makes it difficult to use in neutral to alkaline soils. Nitrogen fertilizers which acidify the soil may increase the possibility of using this phosphate fertilizer ...

Response of Urochloa mosambicensis genotypes to phosphorus fertilization in soil with low phosphorus levels

Revista Brasileira de Saúde e Produção Animal, 2023
Phosphorus (P) is one of the main nutrients capable of increasing yields of tropical grasses. The definition of adequate P fertilizer rates can contribute to improving forage production of pastures.

Conventional and chlorophyll meter–based nitrogen fertilization management for sweetpotato in the tropics

Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Sweetpotato [Ipomoea batatas (L.) Lam.] exhibits low nitrogen (N) uptake during early growth stages, suggesting that N fertilization at planting may be unnecessary. A portable chlorophyll meter can be a useful tool for more precise determination of the timing and rate of topdressed N applications, thereby aligning fertilization with crop ...

The use of light-transparent acetate sheet to measure canopy height of marandu palisadegrass: the influence of development stage and sward height

Bioscience Journal, 2022
The use of light-transparent acetate sheet (LAS) may generate variations in the height measured in the sward. However, we compared the use or non-use of LAS to measure the average sward height of marandu palisadegrass (Urochloa brizantha syn.

Associative diazotrophic bacteria and forage legumes sustain brachiariagrass pasture performance through enhanced root traits

Crop Science, Volume 66, Issue 4, July/August 2026.
Abstract Interest in microbial plant growth‐promoting processes, particularly biological nitrogen (N) fixation (BNF), has increased globally as a strategic alternative to mineral N fertilization. Understanding the response of root traits to diverse N sources plays a critical role in unraveling canopy dynamics and improving decision‐making in forage ...
