Abstract

Peru has a great potential for forestry plantations, nevertheless, importations of this type of products are getting very expensive. Soils under forest are acidic and infertile to support sustainable economically valuable forest tree species such as teak. Information is lacking on proper fertility management in forest plantations such as teak. Therefore, the objective of this study was to explore the effect of lime, and organic and inorganic fertilizers on the early growth and nutrient composition of 12-month old teak grown on acidic soil of Peru. The soil under field study was acidic with a pH of 4.99, low in fertility. A factorial design of 2x3: Lime (No Lime and Liming) and fertilizer (organic, inorganic and mixture), with 9 repetitions was adopted. Tree biometric parameters (height, diameter, biomass) and N, P, K, Ca, Mg, Fe, Cu, Mn, Zn foliar concentrations were determined during early the growth of teak. Treatments with addition of dolomite lime favored higher biometric parameters, and use of organic fertilizers promoted more growth than inorganic fertilizers. In the case of nutrients, no major differences were observed between limed and unlimed treatments while organic fertilizer promoted Ca, K and S nutrition. The results show that the application of lime and organic fertilizers is essential for the successful management and establishment of teak plants in acidic soils of Peru.

石灰和肥料对秘鲁酸性土壤上12月龄柚木生长和营养的影响

秘鲁有巨大的林业种植潜力，然而，这类产品的进口变得非常昂贵。森林下的土壤是酸性的和贫瘠的，以支持可持续的有经济价值的森林树种，如柚木。缺乏关于柚木等森林种植园适当肥力管理的信息。因此，本研究的目的是探讨石灰、有机和无机肥料对生长在秘鲁酸性土壤上的12个月树龄柚木早期生长和营养成分的影响。实地调查的土壤呈酸性，pH值为4.99，肥力较低。采用2x3的析因设计：石灰（无石灰和石灰）和肥料（有机、无机和混合），重复9次。在柚木生长早期测定了树木的生物特征参数（高度、直径、生物量）和N、P、K、Ca、Mg、Fe、Cu、Mn、Zn的叶面浓度。添加白云石石灰的处理有利于更高的生物特征参数，使用有机肥料比使用无机肥料促进更多的生长。在养分方面，石灰处理和未石灰处理之间没有观察到主要差异，而有机肥促进了Ca、K和S的营养。结果表明，施用石灰和有机肥料对于在秘鲁酸性土壤中成功管理和建立柚木植物至关重要。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
