Nutrient Balances

Nutrient balances are recognised as the key to understanding the environmental context for sustainable management in pastorally used mountain lands and for monitoring possible effects of pastoral practices on the life-supporting capacity of soil. The paper draws on a larger survey of recent and current soil fertility research in the high country to examine briefly, three themes in nutrient cycling. The role of nutrient accessions to open systems is recognised for improved range. Current long-term revegetation studies show the need to take account of income from rock weathering. The importance of understanding the role of different plant species, soil amendments and pastoral practices in activating or impeding nutrient cycling proper is indicated from recent studies involving monitoring of exchangeable aluminium, comparing lupins with other legumes and studying the effects of planted conifers on the mineralisation of grassland organic matter. The dimensions and magnitudes of grazing-induced -nutrient-transfers-are-outlined-in-relation-to-their. risks of loss from periodic hydrologic events, as well as recognising the roles of pasture improvement and grazing management in accelerating nutrient cycling. Keywords: aluminium, grazing transfers, mineralisation of organic matter, nutrient balances, nutrient cycling, rock weathering, sustainable management

Ketapang area is one of lower part or southern sub-province of West Kalimanatan Province, which is located geographically between 108o40’ and 111o20’ in Longitude and between 0o20’ and 3o04’ in Latitude. This area has various of industrial mineral resources, for example quartz sand. Quartz sand or also calledwith white sand is the reasult of rock weathering that contents main mineral, such as quartz, and felsdpar. Then, the result of weathering is cleaned and transported by water or wind and deposited in the stream side, lake or sea. In this paper will bedescribed concerning to locations, characteristics, and usages of quratz sand in Ketapang area, West Kalimantan Province. Based on chemical or laboratory analysis and interpretation, the quartz sands can be used as glass industry, cement industry material, and moulding industry.
