NITROGÊNIO TOTAL DE UM SOLO SUBMETIDO A DIFERENTES MÉTODOS DE PREPARO E SISTEMAS DE CULTURA

Cimélio Bayer, J. Mielniczuk

Short summary

Five years after implementation, no-till farming and reduced tillage methods showed a higher capacity to recover total soil nitrogen (NT) compared to conventional tillage in a degraded Paleudult soil.

Key points

  • Soil preparation methods significantly influence total nitrogen (NT) recovery.
  • No-till and reduced tillage methods demonstrated superior NT recovery over five years.
  • Conventional tillage resulted in lower NT levels compared to other methods.
  • The experiment was conducted on a degraded Paleudult soil in Eldorado do Sul (RS).

Abstract

RESUMO Em solos degradados, a baixa disponibilidade de nitrogênio é uma das principais limitações à produtividade das culturas. Um experimento instalado num solo podzólico vermelho-escuro (Paleudult), na Estação Experimental Agronômica da UFRGS, Eldorado do Sul (RS), foi amostrado após cinco anos para determinar a capacidade de recuperação do conteúdo de nitrogênio total (NT) por métodos de preparo e sistemas de cultura. Os tratamentos constaram de métodos de preparo do solo (convencional, reduzido e sem preparo), de sistemas de cultura (aveia/milho, [...]
