Abstract

The addition of ameliorant Fe3+ and rock phosphates containing high Fe cation can reduce effect of toxic organic acids, increase peat stability through formation of complex compounds and reduce carbon emission. The research was conducted in the laboratory and green house of the Departement of Soil Science, Faculty of Agriculture, Bogor Agriculture University. Peat samples with hemic degree of decomposition were taken from Riau. Rock phosphates were taken from the rock phosphates of PT. Petrokimia Gresik, Christmas Island phosphates, and Huinan China and FeCl3.6H2O was used as the other Fe3+ source.  The aims of the research were to study (a) the effect of the applications of ameliorant Fe3+ and rock phosphates on the P content of plants dan (b) the effect of the application ameliorant Fe3+ and the contribution of Fe cation in rock phosphates in the decrease of carbon emission. The results showed that the P content of plants rice increased 58 – 286 % with the applications of ameliorant Fe3+ and rock phosphates. The estimation of carbon loss through CO2 and CH4 emissions from peats if planted continuously with rice was around 2.5, 2.2 and 2.6   Mg of C ha-1 year-1 respectively in field capacity condition, two times of field capacity condition, and 5 cm of saturated condition.  The application of ameliorant Fe3+ and rock phosphates containing high Fe cation increased the stability of peats and reduced the carbon loss around  1.7 Mg of C ha-1 year-1 (64%) in 5 cm of saturated condition, 1,3 Mg of C ha-1 year-1 (58%) in two times of field capacity condition, and 1.0 Mg of C ha-1 year-1 (41%) in field capacity condition.

Abstract

The growth of oil palm plants, such as height, additional fronds, and stem diameter, depends on the soil condition and its physical properties. Good soil physical properties will support the growth of oil palm plants. On marginal lands such as ex-mining land and sub-soil soil that has poor soil physical properties, improvements must be made. Thus, palm oil cultivation on ex-mining land or subsoil land can grow well. This research aims to study solid application to various soil conditions to improve the growth and physical properties of oil palm plants. The land applied by solid is an ex-mining land subsoil land. Meanwhile, the land with flat topography has not been degraded as a control. The data analysis carried out is an orthogonal contrast test, between control with solid application and without solid application, between solid application with without solid, between among solid application (ex-mining and subsoil land), between among without solid application (ex-mining and subsoil land). The research result shows that soil physical properties and plant growth applied with solid are better than without solid, lower bulk density value, higher total pore space and water holding capacity, taller plant growth, higher palm branches quantity, larger stem diameter. Solid application in ex-mining is lower than solid application on sub-soil, with lower water holding capacity value and lesser palm fronds addition. Without solid application on ex-mining sites, the results are worse than no solid application on sub-soil, with lower water holding capacity and lower plant height. Control is better than solid and without solid applications, higher plants, higher addition of frond quantity, and larger stem diameter.
