Abstract

The objective of research was to study mineral N content in soil of PG Jatiroto sugarcane plantation, Lumajang, East Jawa. Mineral N of soil is very important data in utilizing the precise N fertilization method. Rate based fertilization had been discontinuedly utilized by some advanced countries since 1980s because it was considered to be environmentally unfriendly, not appropriate for precision agriculture which oriented toward inner quality.  In the future, Indonesia is also expected to implement the method of accurate N supply on sugarcane to replace the rate based method. Nitrate and ammonium content in soil analized using Cataldo method and  Conway Dish method. Soil samples were taken on two kind of soil texture (sandy soil and loamy soil). Result: content of mineral nitrogen in soil of sugarcane plantation was unexpected extrimly high (2.000-10.000 kg/ha) compare to nitrogen need of sugarcane for yielding highest sugar content (around 350 kg N/ha), nitrate-Nitrogen in general, was very much lower (20-150 kg/ha) than ammonium-Nitrogen (2.500-9.800 kg/ha). Conclusion: mineral N in soil of sugarcane plantation of PG Jatiroto extrimly high and much higher than need of N of sugarcane to produce high sugar content, ammonium-N was the majority of mineral N form in both of soil types.. Keywords: sugar plantation, soil, nitrogen-mineral, nitrate, ammonium

Abstract

Vegetable quality is determined by the physical properties, chemistry, color, and taste. Since increased public awareness of health, their demand on food quality has alsoincreased. Chemical properties of vegetables include: level of nitrate, pesticide residue andheavy metal content. The purpose of this paper is to provide information to Indonesianvegetables stakeholder, the European markets impose strict conditions on levels of nitratevegetables. The method used is the study of literature from a variety of credible sources. Inthe human’s stomach is reduced nitrate to nitrite, then nitrite reacts with amines to formnitrosamine compound. Nitrosamine is known as a very potential carcinogenic compound,with risk of 90%. Statistically, 72.4% of daily nitrate intake originated from vegetables,equal to 35.7 mg/day. Besides forms nitrosamine, nitrite couse methemoglobinamie (babyblue syndrome). Nitrate is very serious threat to human health, so that the WHO limit the maximum daily nitrate intake do not exceed 220 mg (Scharpf and Wehrmann, 1991). To protect their citizen against nitrate hazard, European government are agreed to limit themaximum nitrate content in vegetables. Each species of vegetable and Country has differentnitrate limit. Indonesian’s vegetable contain high nitrate level and difficult to reducebecause there is no technology have been developed to quantify N supply to achieve lownitrate content. Growers in developed countries (Europe, USA, Japan, and Canada) applyN-mineral Metode to maintain nitrogen supply and nitrate content. Wijaya (2012) haveanalyzed 5 species of vegetables (spinach, pachoy, cabage, lettuce and chinakol) resfectivlycontain 6.427, 3.915, 1.847, 1.553, and 704 mg/kg FS). Acording to these nitrate contentand nitrate limiting role of European Countries, very hard for Indonesia to exportIndonesian vegetables to Europe.

Abstract

Intensive nutrient managements for crop production are one of agriculture management strategies that are not yet widely adopted in most third world countries.Precise N Fertilization as a part of intensive nutrient managements is a great way tomanage input efficiency; yet, the technology is feasible enough for farmers to apply, inorder to increase the farm product quality while improve access in modern market.Nitrogen (N) required for plant growth and development in large numbers, but the plant isonly capable of absorbing an average of less than 50% N provided through conventionalfertilization. Greenhouse gases emissions are increasing mostly because of expanding useof N fertilizers, while the carcinogenic effect of N residue on farm products is a dangerousrisk for human health. By increasing the awareness on health and environmental effects forfarm products especially concerning precise N fertilization, consumer will get healthbenefit while producer will get an added value for their products. Thus, by applying betterinput efficiency farmers could simultaneously increase the price while meeting the higherconsumer demands even with gradually stricter standards in term of farm product qualityand market requirements.
