7.4.2
The unit of certification has LSU and leaf analysis procedures with No. Ext. Serv Kal 1-01/01 which was made in November 2005 which regulates the preparation for determining the sampling unit, determining the sampling pattern for each LSU, preparing tools and materials for sampling purposes, arranging the sampling organization and training for the sampling team.
Sampling was carried out for the first time when the plants were 3 years old and then continued at 1 year intervals for sampling. Based on the time of sampling, the plantations were divided into 2 groups, namely the early year group (February-March) and the mid-year sampling group (June-August).
In addition, the certification unit has a procedure for leaf analysis (SOP Leaf Sampling Unit No. PM 0901 dated April 01st, 2010) which aims that the results of leaf analysis are a key factor in determining the recommended dose. In addition, the accuracy and accuracy of the results of leaf analysis depends on the method of taking the leaves). true leaf samples in the field.
the unit of certification has demonstrated the procedures for taking the soil survey as stated in Procedure no. ExtServ. Cal. II-01/01 which contains, among others, the mechanism for preparing the survey, gathering information about the survey area, making a base map and making a preliminary map. The Company has also demonstrated the detailed soil survey procedures listed in Procedure No.
Ext. serv. Kal II-02/01 which contains, among others, the mechanism for taking soil samples
In the guidelines for sustainable plantation management No 724/TQEM-SPMS/09 dated August 27th, 2010 it is stated that soil checks are carried out a maximum of every five (5) years to determine the nutrients contained in the soil.
Soil Sample Analysis
The company has shown the soil sampling documents in Division I MDE PT. BNS contains, among others, conditions of organic matter at a depth of 0 to 30 cm including pH 3.73, Nitrogen 1.24%, P Total 5,756.91, calcium Total 1.00, Magnesium 0.94 Cu 140.69 ppm, Zn 138.69 ppm dan CEC value of land 78.32 cmol kg.
Leaf Sample Analysis
The company has shown the RSE leaf sampling document conducted by MRC with a test report No. P3/2020. Leaf analysis was carried out on 23 February 2021. Leaf samples analyzed included ASH 3.44 – 3.83, P 0.1640 – 0.1700, K 0.9280 – 1.0120, Mg 0.3470 – 0.4050, Ca 0.460 – 0.513, N 2.71 – 2.80
7.4.3
Based on the 2011 Peat Depth Survey Report, it was explained that the organic matter content in the area of PT. BNS is already very high. Therefore, the unit of certification does not carry out EFB or POME application activities. The resulting EFB is burned in a factory furnace, then the ash from the combustion is taken and used as a mixed material for planting media in nurseries. Meanwhile, the POME produced is discharged into water bodies after going through several processes so that it is feasible in accordance with applicable laws and regulations
7.4.4
The unit of certification has records of fertilization for the period January to December 2021 in MDE and RSE which are documented in monthly reports. Manuring activities have been carried out in accordance with the fertilizer recommendations issued by the MRC.
The results of the interview with the Manuring Foreman at revealed that the unit had applied fertilizer according to the company's plan.
Based on the results of the document review, there are records of fertilization in MDE and RSE. For example, the following is the monitoring of Manuring data in RSE for the period January to December 2021
