The Distribution of Base Metals and Platinum-Group Elements in Magnetitite and Its Host Rocks in the Rio Jacaré Intrusion, Northeastern Brazil
(Brasil, 2005)
Anomalously high Pt and Pd values have been found in three magnetite bodies in the Rio Jacaré intrusion of northeastern Brazil. The intrusion hosting these magnetite bodies consists predominantly of pyroxenite and gabbro. ...
The cedrolina chromitite, Goiás State, Brazil: A metamorphic puzzle
(2016-09-01)
The Cedrolina chromitite body (Goiás-Brazil) is concordantly emplaced within talc-chlorite schists that correspond to the poly-metamorphic product of ultramafic rocks inserted in the Pilar de Goiás Greenstone Belt (Central ...
Contribution of different sources and origins of nitrogen in above- and below-ground structures to the partial nitrogen balance in soybean
(Springer, 2022-04)
Aims: Most studies that quantified the biological N fixation (BNF) and partial N balances of soybean have ignored the belowground structures. Our objectives were to evaluate the contribution of belowground structures to ...

Nitrogen dynamics in field grown comice pears
(Oregon State University, 1990-05)
The dynamics of N was studied in field grown Comice/Provence quince BA29 pears in Medford, Oregon. Total tree biomass, N content, and ¹⁵N evaluations suggest that young pears require little N (48 kg N ha⁻¹ yr⁻¹). About 45% ...
The urea transporter DUR3 is differentially regulated by abiotic and biotic stresses in coffee plants
(2021-02-01)
The high costs of N fertilizers in the coffee production emphasizes the need to optimize fertilization practices and improve nitrogen use efficiency. Urea is widespread in nature, characterizing itself as a significant ...
