O Minist\u00e9rio da Agricultura e Pecu\u00e1ria (Mapa) informa que foram atualizados os dados do Zoneamento Agr\u00edcola de Risco Clim\u00e1tico (Zarc) para a cultura do milho 1\u00aa safra no Rio Grande do Sul<\/em><\/p>\n

Ap\u00f3s a publica\u00e7\u00e3o das portarias referentes ao zoneamento, foram recebidas manifesta\u00e7\u00f5es do setor produtivo sobre o calend\u00e1rio de semeadura em munic\u00edpios da regi\u00e3o noroeste do estado. As demandas foram encaminhadas para reavalia\u00e7\u00e3o pelo grupo de trabalho respons\u00e1vel pelo Zarc do milho.<\/p>\n

Na revis\u00e3o, a equipe t\u00e9cnica da Embrapa identificou um equ\u00edvoco na programa\u00e7\u00e3o de p\u00f3s-processamento dos dados relativos ao m\u00eas de agosto, referente aos dec\u00eandios cr\u00edticos para ocorr\u00eancia de geada. Na configura\u00e7\u00e3o utilizada, foram considerados como cr\u00edticos os dec\u00eandios da semeadura, quando o correto era considerar os dec\u00eandios da fase de p\u00f3s-emerg\u00eancia da cultura. Como consequ\u00eancia, o risco de geada em alguns munic\u00edpios foi superestimado, impactando as janelas indicadas para semeadura.<\/p>\n

Os dados foram corrigidos e j\u00e1 est\u00e3o dispon\u00edveis no\u00a0Painel de Indica\u00e7\u00e3o de Riscos<\/span><\/span>.<\/p>\n

Com a atualiza\u00e7\u00e3o, os resultados passaram a refletir a metodologia adotada para o zoneamento da cultura, mantendo diferen\u00e7as em rela\u00e7\u00e3o \u00e0 safra anterior em raz\u00e3o das altera\u00e7\u00f5es metodol\u00f3gicas incorporadas nesta vers\u00e3o.<\/p>\n

Entre as mudan\u00e7as implementadas no Zarc para a cultura do milho est\u00e3o a atualiza\u00e7\u00e3o da base de dados meteorol\u00f3gicos, com utiliza\u00e7\u00e3o da s\u00e9rie hist\u00f3rica de 1992 a 2022 e amplia\u00e7\u00e3o do n\u00famero de esta\u00e7\u00f5es meteorol\u00f3gicas consideradas, al\u00e9m da ado\u00e7\u00e3o do modelo de classifica\u00e7\u00e3o de solos em seis n\u00edveis de \u00e1gua dispon\u00edvel (AD). A classifica\u00e7\u00e3o considera a propor\u00e7\u00e3o de areia, silte e argila no solo, substituindo o modelo anterior, que utilizava tr\u00eas classes de solo (arenoso, m\u00e9dio e argiloso).<\/p>\n
