The <strong>IOI</strong> Research Centre is carrying out field trials to investigate “Sustainable Agriculture” scientifically and practically,especially in maximising fertiliser-use efficiency and reducing soil erosion on sloping terrain. Shade-tolerant perenniallegume species (Mucuna bracteata) are being planted to promote nitrogen fixation, organic matter and soil conservationthroughout the life span of the palms.Biodiversity which is an important component of sustainability is also greatly emphasised by the Company. Variousspecies of timber trees, tropical fruit trees and flowers are planted around estate offices and housing complexes. One hasjust to visit our agro-tourism project at Sagil Estate (near Tangkak) to appreciate the commitment the Company has toconserve biodiversity. Timber species, e.g. teak, are also being tested on a trial basis.Biological control is integrated into pest management practices to minimise usage of pesticides. Beneficial plants (e.g.Cassia cobanensis and Tunera spp.) are planted to attract natural predators for biological control of bagworms and otherleaf-eating caterpillars which are major insect pests in oil palm plantations. Barn owl boxes are erected in the estates toincrease the owl population for biological control of rats which can cause significant yield reduction. We are probablyalso the largest user of buffaloes in oil palm estates for the industry. The large-scale use of buffaloes to complementmachines for infield collection of fruit bunches has led to reduction in soil compaction, biological weed control and tosome extent nutrient recycling, besides eliminating the need for non-renewable diesel fuel to run collection vehicles inthe fields.In integrated weed management, herbicides are selectively used to eradicate noxious weeds. Soft grasses are maintainedto prevent soil erosion. Where practical, mechanical weed control is practised to minimise use of herbicides.By-products from palm oil mills especially empty fruit bunches (EFB) and effluent decanter cakes are used wherenecessary as organic fertilisers to enhance yields resulting in cost-effectiveness in our fertiliser practices.EFB fibre is used as biofuel for power generation in palm oil mills and refinery. The <strong>Group</strong> is also studying the use of EFBas raw material for pulp and paper manufacturing. This will certainly add value to our oil palm plantations and enhancecompetitiveness.59<strong>IOI</strong> Corporation BerhadAnnual Report 2003
