Abstract

Martinus et al, 2017. Acacia crassicarpa Seedling Growth with Bokashi from Variety Ingredient. JLSO 6(2):185-191.The provision of nutrients for plants in HTI (Plantations Industries), especially at the time of seeding, can be done with the addition of organic and inorganic fertilizers. Inorganic fertilizers can provide nutrients quickly. However, if this is done continuously will cause the soil damages. Meanwhile, although organic fertilizers provide slow nutrient, it can be improve physical and chemical soil. One kind of organic fertilizer is Bokashi., Bokashi compost is produced from the fermentation process. This study aims to determine the effect of variety ingredient of Bokashi as nursery media makers on  A.crassicarpa seedling growth. This trial uses design complete randomized design (RCD), with four replications and 7 treatments. Treatments include (A) NPK, (B) Kumpai, (C) Desmodium, (D) Salvinia (E) A. Crassicarpa, (F) A. Mangium, (G) E. pellita. The experimental results showed that the main ingredient kiambang bakashi giving a better effect on the growth of A. crassicarpa in the nursery than kumpai, Desmodium, leaf litter A. mangium, A. crassicarpa, E. pellita and control (NPK).

Abstract

Industrial Forest Plantations (IFP) are intended to increase the productivity non-productive natural forest production. In South Sumatra Province IFP is widely developed in wetlands; one of them is in acid sulphate soils which have major problems with flooding and waterlogging. To solve this problem, the technology other than  making drainage canals is Bed Raising. Bed Raising is to make beds to facilitate the implementation of planting, maintenance and harvesting, in addition to maintaining good soil aeration conditions. However, Bed Raising on acid sulphate soil raises a new problem is pirite oxidation, which affects the chemical properties of acidic sulphate soil. The purpose of this study was to see the benefits of bed raising in the management of acid sulphate land in IFP areas. This study uses survey methods and data are presented in tabulations. The results of this study indicate that the benefits of bed raising in the management of acid sulphate land are no longer flooded or waterlogging. While the results of chemical analysis of soil in bed raising plots are very acidic soil pH (pH <3), Al-dd saturation is very high (> 70%), and high pyrite concentration (> 2.4%). This value is not suitable for plant growth.
