chernozêmico textura média e argilosa (ocorre em<br />

âreas <strong>de</strong> simbolos PE6 e PEU).<br />

78 — SOLOS LITÓLICOS EUTRÓFICOS A fraco, mo<strong>de</strong>ra<strong>do</strong><br />

e chernozêmico textura arenosa e 'média (ocorre<br />

em âreas <strong>de</strong> simbolos PE3, PE4, BV1, BV2,<br />

BV3 e Re3).<br />

79 — SOLOS LITÓLICOS EUTRÓFICOS A fraco e mo<strong>de</strong>ra<strong>do</strong><br />

textura média e argilosa (ocorre em âreas<br />

<strong>de</strong> simbolos NC6 e Ce).<br />

\<br />

Abränge âreas das zonas fisiogrâficas <strong>do</strong> Litoral e partes <strong>do</strong>s sertôes Centro-<br />

Norte, Central e <strong>do</strong> Su<strong>do</strong>este. Compreen<strong>de</strong> <strong>solos</strong> <strong>de</strong>riva<strong>do</strong>s <strong>de</strong> gnaisse, migmatito<br />

e granito. Relevo forte ondula<strong>do</strong> e. montanhoso com altitu<strong>de</strong> varian<strong>do</strong> <strong>de</strong> 3<strong>00</strong> a 350<br />

métros no Litoral e 550 a 7<strong>00</strong> métros nas <strong>de</strong>mais âreas. Clima Aw' e BSw'h' <strong>de</strong><br />

Koeppen e 4bTh, 4aTh <strong>de</strong> Gaussen, com precipitaçâo pluviométrica média anual <strong>de</strong><br />

9<strong>00</strong> a 1.1<strong>00</strong> mm (Litoral) e 550 a 650 mm (Sertôes). Vegetaçâo <strong>de</strong> transiçâo, floresta/<br />

caatinga.<br />

Abränge âreas das zonas fisiogrâficas <strong>de</strong> Baturité, Litoral e sertôes Central e<br />

Centro-Norte. Compreen<strong>de</strong> <strong>solos</strong> <strong>de</strong>riva<strong>do</strong>s <strong>de</strong> gnaisse, migmatito, micaxisto, granito<br />

e anfibolito (pequenas âreas). Relevo forte ondula<strong>do</strong> e montanhoso excetuan<strong>do</strong>-se<br />

as âreas <strong>de</strong> simbolo BV1 e BV3 que se apresentam com relevo suave<br />

ondula<strong>do</strong> e ondula<strong>do</strong>. Altitu<strong>de</strong>s varian<strong>do</strong> <strong>de</strong> 2<strong>00</strong> a 7<strong>00</strong> métros, atingin<strong>do</strong> cerca<br />

<strong>de</strong> 9<strong>00</strong> métros nas partes mais elevadas da serra <strong>de</strong> Baturité. Clima Aw' e Amw'<br />

(Baturité), <strong>de</strong> Koeppen e 4bTh, 4cTh, 6b (Baturité) <strong>de</strong> Gaussen, com precipitaçâo<br />

pluviométrica média anual <strong>de</strong> 1.1<strong>00</strong> a 1.3<strong>00</strong> mm nas âreas <strong>do</strong> Litoral e Baturité,<br />

atingin<strong>do</strong> nesta ultima area valores <strong>de</strong> até 1.7D0mrn. Para as <strong>de</strong>mais regiôes<br />

pre<strong>do</strong>minam as precipitaçôes que variam <strong>de</strong> 6<strong>00</strong> a 950 mm. Vegetaçâo <strong>de</strong><br />

floresta subcaducifólia (Baturité e Litoral) e <strong>de</strong> transiçâo floresta/caatinga e<br />

caatinga hipoxerofila nas <strong>de</strong>mais âreas. •<br />

Situa-se em âreas das zonas fisiogrâficas <strong>do</strong> Araripe e sertâo <strong>do</strong> Baixo Jaguaribe.<br />

Os <strong>solos</strong> da ârea <strong>de</strong> simbolo NC6 sào <strong>de</strong>senvolvi<strong>do</strong>s <strong>de</strong> gnaisse, migmatito,<br />

filonito e granito, enquanto que os da associaçâo Ce originam-se <strong>de</strong> calcârio da<br />

Formaçào Jandaira <strong>do</strong> Cretâceo. Relevo piano (Ce) e suave ondula<strong>do</strong> e ondula<strong>do</strong><br />

(NC6) com altitu<strong>de</strong>s varian<strong>do</strong> <strong>de</strong> 120 a 140 métros (ârea Ce) e 5<strong>00</strong> a 6<strong>00</strong><br />

métros (ârea NC6). Clima BSw'h' <strong>de</strong> Koeppen e 4aTh <strong>de</strong> Gaussen, com precipitaçâo<br />
