INDRAWAN, NIM. 2110246849, EFFECTIVENESS OF CONTROLLED LOSAGE FERTILIZER FILTER CONTAINERS (WPLST) IN PROVIDING
NUTRIENTS OF PALM PALM (Elaeis guineensis Jacq.) ON PEAT SOILS WITH DIFFERENT GROUND WATER DEPTHS, supervised by Syafrinal and Wawan.

Oil palm plantations on peat lands are faced with various obstacles for their growth such as high levels of saltiness, the availability of nutrients N, P, K, Ca and Mg in low-lying soils, although the N-Total content is relatively high, but in organic form. Proper management, including the application of fertilizer to peat soils, will provide great benefits for oil palm growth. The cost of fertilization in coconut plantations reaches 60% of the maintenance cost. High nutrient leaching in peat soils is often a problem that leads to low fertilization efficiency. One solution is to use CRF (Control release fertilizer) fertilizer, however, it is expensive. Another alternative to fertilization is to use controlled loose fertilizer filter containers (WSPLT) in dissolving NPK, WSPLT fertilizers and groundwater level of 40 cm and 60 cm in peat lands.
This study was carried out experimentally using the Split Plot Design, namely the water level (Main Plot) and controlled loose filter fertilizer containers (Sub Plot), the Main Plot is the water level with the following levels: A1= Water level height 40 cm, A2= Water level height 60 cm. Sub Plot is a controlled loose filter fertilizer container (WPSLT) with the following levels: W1= Without fertilizer container, W2= Filter fertilizer container 60 mesh, W3= Filter fertilizer container 80 mesh, W4= Filter fertilizer container 100 mesh. Each treatment was repeated 3 times, so that 24 experimental units were obtained. Each experimental unit consists of one sample tree so that the total number of sample trees used is 24 trees.
The results showed that the difference in the size of the WSPLT filter at different water levels resulted in a percentage of fertilizer solubility that was not different. Different water levels result in different percentages of fertilizer solubility. Fertilizer application using WSPLT results in a lower percentage of solubility compared to no WSPLT. The use of WSPLT with different sieve sizes resulted in a different percentage of solubility. The values of soil chemical properties pH (H2O), pH (KCl), C-Organic, N total, P total, P available, K, Ca, Mg, Na and KTK do not differ at different groundwater table heights. The total K value and KB are different for different groundwater table heights. The N nutrient content in leaves was different between the application of fertilizer without WSPLT and the application of fertilizer using WSPLT in all treatments. The P nutrient content in leaves is no different between no WSPLT and using WSPLT, the K nutrient content in leaves is different in some fertilizer treatment without WSPLT and fertilizer application

Keywords: peat, controlled release filter fertilizer container, leaf nutrient content
