About the Book

Les sols doivent être correctement étudiés et équilibrés, et une fertilisation adéquate des cultures est nécessaire pour rendre les ressources du sol durables. L'État d'Azad Jammu & Kashmir (AJK) est divisé en huit zones agro-écologiques qui vont des glaciers et calottes glaciaires qui sont couverts de neige toute l'année (Zone 1), à la zone alpine tempérée très froide sans mousson (Zone 2), tempérée froide sans mousson (Zone 3), Zone alpine de mousson tempérée très froide (Zone 4), Zone alpine de mousson tempérée froide (Zone 5), Zone tempérée chaude humide (Zone 6), Zone sub-tropicale chaude humide (Zone 7) et Zone sub-tropicale chaude sub-humide (Zone 8) en partant du nord au sud de AJK. Dans cette étude, des échantillons composites de sol ont été collectés à une profondeur de 30 cm dans les zones 3, 5, 6, 7 et 8 et ont été analysés pour les propriétés physiques et chimiques du sol. La zone 3 a montré un statut de fertilité plus élevé par rapport aux autres zones. Le pH du sol dans la zone 3 était acide par rapport aux terres cultivées dans les zones 6 et 8 qui étaient légèrement alcalines par nature. La comparaison globale de la fertilité des terres cultivées a montré que les terres cultivées étaient déficientes en matière organique, phosphore disponible et potasse de 30, 37 et 23 % respectivement.
