INFILTRASI DAN LIMPASAN PERMUKAAN PADA POLA TANAM AGROFORESTRI DAN MONOKULTUR : STUDI DI DESA JERU KABUPATEN MALANG
ABSTRACT: The research aims to
determine rate of water infiltration and soil run off on agroforestry, parennial
and annual monoculture cropping systems was conducted at Jeru village Malang
Refency. The water infiltration rate was measured byinfiltrometer and the soil
run off was measured simple ranfall simulator to make run off on the soil. The
run off water and soil flowing was
sheltered into a glass and then weighing the dry mass of the soil. Parameters
observed were pl ant species, trees architectures model, the amount of litter
in the land. The results showed that the highest water infilt ration rate and
the lowest soil run off was on multiculture agroforestry each 63,5 cm.h-1 and
0,3 g.lt-1 whereas the lowest water infiltration and the highest soil run off
was on perennial trees monoculture cropping system each 30 h -1 and 2,9 g.lt-1
. The multiculture agroforestry was dominated by ‘waru gunung’ (Hibiscus
macrophyllus), ‘mindi’ (Melia azedarach), ‘mahoni’ (Sweitenia macrophylla),
bamboes and cassava
(Manihot esculenta) that
have different tree
architecture models. The diversity of the tree species also
caused varying litters produced.
