在农业科学中，土壤肥力和植物营养在20世纪提高作物产量方面发挥了重要作用。在21世纪，由于自然资源(土地和水)、可持续农业以及人们对环境污染的关注，这一领域的重要性仍在不断扩大。在此背景下，作物产量的提高将与合理使用化肥、增加有机营养源的使用、植物有效养分的循环利用以及开发作物物种或物种内品种的遗传潜力以有效利用养分有关。因此，在未来，提高作物产量将是农业和土壤科学家面临的挑战。在不同的农业生态区进行化肥田间试验，以确定充足的来源、方法、用量、施肥期以及物种内的作物种类或基因类型，对于产生数据及其使用，以实现最大的经济作物产量是必要的。本文的目的是介绍田间条件下土壤肥力和植物营养研究的基本概念和方法。
In the agricultural science, soil fertility and plant nutrition have played an important role during the 20th century in increasing crop yields. In the 21st century, importance of this field is still expanding due to the limitations of natural resources (land and water), sustainable agriculture, and concern about environmental pollution. In this context, increasing crop yields will be associated with rational use of chemical fertilizers, increasing use of organic sources of nutrients, recycling of plant available nutrients, and exploiting genetic potential of crop species or cultivars within species in efficient use of nutrients. Hence, in the future, increasing crop yields will be a challenge for agricultural and soil scientists. Conducting fertilizer field trials for adequate sources, methods, rates, timing of application along with crop species or genotypes within species, under different agroecological regions are necessary to generate data and their use for achieving maximum economic crop yields. The objective of this article is to present basic concepts and discuss methodology of soil fertility and plant nutrition research under field conditions.
