Influence of nitrogen and phosphorous on the growth and root morphology ...
Abstract. Nitrogen and phosphorous are critical determinants of plant growth and productivity, and both plant growth and root morphology are important parameters for evaluating the effects of supplied nutrients. Previous work has shown that the growth of Acer mono seedlings is retarded under nursery conditions; we applied different levels of N ...

Why phosphorus is important - NSW Department of Primary Industries
Soils. Fertilisers, amendments and testing. More topics in this section. Phosphorus is one of the major plant nutrients in the soil. It is a constituent of plant cells, essential for cell division and development of the growing tip of the plant. For this reason it is vital for seedlings and young plants.

Why do we need to put phosphate fertilizers along with rhizobium? Isn't phosphorous a macro nutrient? So it should be present in the soil in sufficient quantities... but still we add phosphate. Why?
**Phosphorus** (P) is a macronutrient and, after nitrogen (N), typically _the_ limiting factor for plant growth. Potassium (K) is also often added in fertilizers. P is an important plant macronutrient, making up about 0.2% of a plant's dry weight. It is a component of important compounds, including ...

磷循环 (文章) | 生物地质化学循环 | 可汗学院 - Khan Academy
土壤中的磷酸盐化合物可以被植物吸收,并从那里转移到以植物为食的动物体内。当动植物排泄废物或死亡时,磷酸盐可能被有害物质吸收或返回土壤。含磷化合物也可以在地表径流中携带到河流、湖泊和海洋,在那里它们被水生生物吸收。
