Effects of Intercropping Acacia Mangium with Peanut (Arachis Hypogaea) on Tree/Crop Growth and Some Chemical Properties of Two Malaysian Soils
Malaysian soils are of low fertility because they are highly weathered soils. Large scale clearance of natural forests and mining activities have resulted in increased erosion and leaching of nutrients thus aggravating this problem of low soil fertility. Two field experiments were conducted in...

| 總結: | Malaysian soils are of low fertility because they
are highly weathered soils. Large scale clearance of
natural forests and mining activities have resulted in
increased erosion and leaching of nutrients thus
aggravating this problem of low soil fertility.
Two field experiments were conducted in 1989 at
Universiti Pertanian Malaysia to determine the effects
of intercropping Acacia mangium with peanut (Arachis
hypogaea) on chemical properties of two types of soils;
a normal mineral soil and a desolated ex-tin mining
soil. A. mangium seedlings were planted in each study
site at four different planting distances namely; 2X2,
2x4, 3x3 and 4x4 meters, with uniform spacing for
peanut (50 cm x 10 cm). Each of the plots in the respective spacing distance was divided into two subplots. |
