KONTRIBUSI MACAM BAHAN ORGANIK DAN KALSIT TERHADAP PERUBAHAN KADAR BESI DAN MANGAN DALAM TANAH SERTA SERAPANNYA OLEH JAGUNG PADA INCEPTISOL ACEH UTARA
Abstract: The Inceptisols is a
soil in great amount and widely distributed in Indonesia, even in the province
of Aceh Inceptisols is the most extensive amount. The Inceptisols were found
from lowland up to highland, and their properties are very vary. Commonly, the
soil fertility of the Inceptisols of lowland are low. Calcite and Organic Matter
are the easy matter found, and to be considered as a better soil amandment.
While maize is improved varieties of crop that its production constantly to be
increased. This experiment was conducted in order to study the contribution of
organic matter as well as calcite contribution to the change of iron and
manganese in soil and uptake by maize at North Aceh Inceptisol. Kinds of
organic matter that was used consist of cow manure and water hyacinth (60:40).
Fully randomized design has been conducted that consist of two combined
treatment factors with three replicated. The factor is related to the kinds of
organic matter was 0.0, 2.0, 3.0 and 4.0 ton ha-1 and calcite were 0.0, 1.0 and
1.5 ton ha-1. The results showed that the aplication of organic matter and calcite
significantly effect on levels of iron and manganese in the soil and plants.
Dose organic material 4 ton ha-1 and calcite 1.5 tons ha-1 is able to increase
at the highest level of the iron content of the soil, while the dose of organic
materials 4 ton ha-1 and calcite dose 0.0-1.0 tonnes ha-1 is the best for the
increasing of manganese in the soil. The highest content of iron and manganese
of maize crop was obtained at a dose of 6.0 tons ha-1 of organic matter without
calcite application.
