Abstract

fetched live from OpenAlex

O objetivo deste estudo foi quantificar variabilidade espacial de salinidade por sódio em área irrigada com resíduo líquido de frigorifico em pastagens de Brachiaria brizantha cv. Marandu cultivadas em plintossolo. As coletas do solo foram realizadas em malha de amostragem regular com distâncias de 32 x 32 m numa área de 7,63 ha. Para a realização da amostragem, utilizou‑se uma rede de 63 pontos georreferenciados, sendo a amostragem de cada ponto composto por quatro subamostras de solo, coletadas na camada de 0 - 20 cm de profundidade, num raio de aproximadamente cinco metros ao redor do ponto principal. Os semivariogramas da salinidade do solo por sódio, se ajustaram ao modelo exponencial, com grau de dependência espacial (GDE), classe forte (99,9%). Os mapas confeccionados permitem identificar unidades de aplicação diferentes quanto à presença do sódio de acordo com as áreas de irrigação com resíduo liquido bovino. Essa regionalização surge como ferramenta auxiliar para o monitoramento da área da pastagem permitindo assim o manejo adequado da irrigação com resíduo líquido bovino.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
