Abstract

The Peruvian Altiplano presents increasing fertility losses, being susceptible to natural erosion. For many years, conventional agricultural management has generated losses of the topsoil and deterioration of soil properties, impacting in crop yields and deepening the degradation of this vulnerable ecosystem. The aim of this research was to determine the benefits of cover crops against erosion, soil health and quinoa yield. The trial was carried out in Huancarani and Cahualla towns, Mañazo district, Puno; with a randomized complete block design (RCBD) with four treatments: without cover and with clover (Medicago hispida G.), vetch (Vicia villosa) and mulch covers. We evaluated the physical, chemical, and biological characteristics of soil, the biomass of the cover crops and the quinoa yield. The results showed that the treatments with clover, mulch and vetch covers reduced soil erosion by 59.61%, 51.87% and 49.50%, respectively. Likewise, the use of clover and vetch covers increased organic carbon (29.71% and 31.16%), nitrogen (36.94% and 48.65%), and available phosphorus with clover cover (26.11%). Finally, clover cover associated with quinoa increased the yield of quinoa grain by 17% and reduced soil erosion significantly. These results show that cover crops have great potential for restoring soil health and improving yield.

秘鲁高原与藜麦相关的覆盖作物:减少侵蚀，改善土壤健康和农业产量

秘鲁高原易受自然侵蚀，肥力损失日益增加。多年来，传统的农业管理造成了表土流失和土壤性质恶化，影响了作物产量，加剧了这一脆弱生态系统的退化。这项研究的目的是确定覆盖作物对土壤侵蚀、土壤健康和藜麦产量的好处。试验在普诺Mañazo区万卡拉尼和卡瓦拉镇进行;采用随机完全区组设计(RCBD)，有四种处理:无覆盖、苜蓿(Medicago hispida G.)、紫薇(Vicia villosa)和地膜覆盖。我们评估了土壤的物理、化学和生物学特性，覆盖作物的生物量和藜麦产量。结果表明，三叶草覆盖、地膜覆盖和野豌豆覆盖处理分别减少了59.61%、51.87%和49.50%的土壤侵蚀。三叶草和紫薇覆盖增加了土壤有机碳(29.71%和31.16%)、氮(36.94%和48.65%)和速效磷(26.11%)。三叶草覆盖使藜麦籽粒产量提高了17%，并显著减少了土壤侵蚀。这些结果表明，覆盖作物在恢复土壤健康和提高产量方面具有很大的潜力。

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.
