Abstract

Following the release of Presidential Regulation No 1/2016, a peat restoration pilot project has been carried out in Banjarbaru District, South Kalimantan in addition to other two pilot projects in other provinces of Indonesia. The pilot project has been designed to implement the three aspects of peat restoration, namely rewetting, revegetation and revitalization of society.  Implementation of revegetation is mainly through applying agroforestry by growing agricultural crops in spaces between trees. The objective of present study was to elucidate the suitability of agricultural crops in area of restoration of degraded peatland in South Kalimantan, Indonesia. The suitability of agricultural crops was studied by collecting rainfall and air temperature data from the climatic station of Syamsudin Noor Airport in Banjarbaru, while the nutrient retentions values were determined in the laboratory. Peat depth and drainage class were determined by direct field observations, while peat decomposition level was classified by quantitative method in the field. All collected data were then used to assess the land suitability class for  dry land paddy (Oriza sativa L), long bean (Vigna sinensis ENDL), cucumber (Cucumis sativus LINN), mustard (Brassica rugose FRAIN), orange (Citrus sp), stink bean (Parkia speciose HASSK), rubber (Hevea brassialiansis M.A), and coconut (Cocus nocifera L). The productivity data of long bean, cucumber and mustard were obtained by farmer interview. The results showed that most of the agricultural crops were classified as marginally suitable (Class S3).The main limiting factors of agricultural development in this area are low soil pH, low base saturation and peat ripening. Peat depth limits the development of some crops. The above mentioned limiting factors ought to contribute to the low crop productivities in the area. The limiting factors were less severe for pineapple and stink bean, indicating that these crops have potential to be grown along with trees for restoration efforts in the area.

Abstract

The distribution area of mineral soil in Indonesia reaches 148 million ha. The acid mineral soil in South Kalimantan for Ultisol reaches 886.186 ha. Ultisols have low fertility and P availability. The low availability of P in the soil is caused by P being absorbed. Isothermal absorption is very useful for measuring P adsorption in the soil due to strong P fixation by Fe and Al in Ultisol soils. Many researchers have suggested determining the amount of P required to reach an optimum level for maximum crop yield to quantitatively describe isothermal adsorption, the most popular of which are Langmuir, Freundlich, and the Brunauer-Emmett-Teller (BET) equations. The purpose of this study was to determine the isothermal adsorption limit of P and describe quantitatively the isothermal adsorption in Ultisols in Banjarbaru City using the Langmuir, Freundlich, and BET equations. From the research results, it can be concluded that P adsorption on Ultisols in Gunung Kupang Village, Cempaka District, Banjarbaru City follows the BET Equation. The high and low P adsorption indicated the availability of P. In other words, the fixation activity of acid mineral soils could result in a smaller amount of available P for plants.
Pengaruh Pemberian Lumpur Padat Limbah Pabrik Kelapa Sawit Terhadap Ketersediaan Hara Pada Tanah Podsolik Dan Produksi Tanaman Jagung: The Effect of Providing Solid Sludge from Palm Oil Mill Waste on Nutrient Availability in Podsolic Soil and Corn Plant Production Fidela Shabrina; Muhammad Syarbini; Abdul Hadi

Abstract

Podzolic soil fertility and health are generally low due to its poor physical and chemical properties. Consequently, the use of organic soil amendments is essential to improve these properties and provide essential nutrients. Palm oil mill sludge solid waste is rich in nitrogen, phosphorus, potassium, magnesium and calcium which makes it a suitable fertilizer. This study aimed to evaluate the effect of palm oil mill sludge solid waste application on the availability of nitrogen, phosphorus and potassium in podzolic soil and corn (Zea mays) production. The experiment was conducted in a pot using a single factor Completely Randomized Design (CRD). The findings showed that application of palm oil mill sludge solid waste to podzolic soil increased the availability of nutrients N-NH4+, N-NO3-, available P and available K and the fresh and dry weight of corn plants. However, it did not increase soil pH. Treatment P4 (20 t ha-1) produced the highest values ​​of N-NH4+, N-NO3-, available P, available K and the fresh and dry weight of corn plants, making it the most effective treatment for the utilization of palm oil mill sludge on Podzolic soil.
