Abstract

The growth of the oil palm industry in Indonesia has been phenomenal. With only 106.000 ha planted in 1968, it has increased to more than 3,393 million ha in 2000. Fertilizer has played a major role in contributing to the advancement of sustainable oil palm yields. Currently with Asian economies experiencing an economic slow down and locally with the depreciation of rupiah, fertilizer costs have inevitably gone up causing the increase of production costs. Recently some plantations are trying to use waste water for fertilising purpose since it known that waste water contains some potential nutrient such as N, P, K and Mg. In Sei Manding this usage increases the production up to 27%.

Abstract

Presently the world is moving away from inorganic fertilizer, weed and pest control. As we know in many countries rice paddies are fertilized with inorganic fertilizer and sprayed with pesticides as a way to control weeds and other pests. This process, however, is harmful to the people, animal and plant life in the surrounding area. The use of Azolla pinata as green manure and source of nitrogen may can be used to reduce the use of inorganic fertilizer.

Abstract

Up until now, some countries still facing food shortage. One of thereasons is waters carcity. As we know, it is estimated that 70 percentof the water consumed worldwide, including that diverted from riversand pumped from underground, is used for irrigation, while some 20percent is used by industry and 10 percent for residential purposes. Inthe increasingly intense competition for water among these three sectors,the economics of water do not favor agriculture. In China, 1,000 tons ofwater can be used to produce 1 ton of wheat, worth perhaps $200, or toexpand industrial output by $14,000—70 times as much. In a countrythat is desperately seeking economic growth and the jobs it generates,the gain in diverting water from agriculture to industry is obvious.
