Agronomy
Agronomy looks at agriculture from an integrated, holistic perspective. Agronomists are specialists in crop and soil science, as well as ecology. Some things they look at are:
- The properties of the soil;
- How the soil interacts with the growing crop;
- What nutrients (fertilizers) the crop needs;
- When and how to apply these nutrients;
- The ways that crops grow and develop;
- How climate and other environmental factors affect the crop at all stages;
- How best to control weeds, insects, fungi, and other crop pests; and,
- How to grow crops effectively and profitably while conserving and protecting the environment.

俗话说“你不知道你有一个问题你就不可能解决问题”，这是诊断植物营养缺乏基础科学的支撑。多年来，很多农民和科学家一起工作，通过多种线索来判断农作物的营养缺乏。这些线索和症状十分有用，特别是在土壤和植物组织试验做不了或行不通时。

Agronomy is the applied science of crop and plant production for food, fibre and energy. It is intrinsically multi-disciplinary – agronomists need to have knowledge of biology, chemistry, ecology, soil and earth sciences, pathology, weed science and genetics. In addition to understanding...
