摘要

水稻(Oryza sativa L.)是一种非常重要的粮食作物,因为其结果被用作印度尼西亚居民的主食。粮食满足度的提高导致了Mojogedang街道大米产量的增加。土壤肥力高的水田,水稻产量高。Mojogedang街道稻田采用有机系统和常规系统管理,不同稻田的管理方式必然影响稻田的肥力水平,因此有必要对土壤肥力指数进行评价。调查区域由10个点组成,采用有机和常规管理制度。所取参数包括土壤的化学和生物特性,包括;pH、氧化还原电位、有机碳、CEC、碱饱和度、有效磷、有效钾、全氮、C/N比和总微生物。使用统计应用程序进行主成分分析(PCA)所获得的数据。然后完成各点土壤肥力指数(SFI)的计算和管理制度的建立。统计分析结果表明,有机管理系统土壤肥力指数为4级或非常高,常规管理系统土壤肥力指数为3级或高。获得的指数值受到K指标的强烈影响,K指标对各种管理系统有显著影响。土壤肥力指数增加,因为使用肥料可以改善植物营养,长期施用。

The Assessment of Soil Fertility Index for Evaluation of Rice Production in Karanganyar Regency
Rice (Oryza sativa L.) is a very important food crop because the result is used as a staple food for residents in Indonesia. Higher food fulfillment leads to the increase of rice production of the Mojogedang sub-district. Paddy fields that have high soil fertility will produce good rice productivity. Rice fields in Mojogedang Sub-district are managed with organic systems and conventional systems, the management of different fields of rice field certainly affects the level of fertility in the paddy fields so it is necessary to evaluate the soil fertility index. The survey area consists of 10 points with organic and conventional management systems. The parameters taken include chemical and biological properties of soil, including; pH, redox potential, C-organic, CEC, base saturation, P available, available K, N Total, C/N ratio, and total microbial. The data obtained by performed analysis of the main component principal component analysis (PCA) using statistical applications. Then after complete the calculation of The Soil Fertility Index (SFI) at each point and management system. The results of statistical analysis obtained soil Fertility Index on organic management systems have a class of 4 or very high and in conventional management systems have a class of 3 or High. The value of the index obtained is strongly influenced by the K indicator available where the indicator has a noticeable effect on the various management systems. Increased soil fertility index due to the use of manure that can improve plant nutrients and applied for long periods.
