Description

The loss of phosphorus from the landscape can negatively affect the environment, with water quality being the primary concern. Within agricultural systems, beneficial management practices are used in the application and management of phosphorus in order to prevent or minimize losses. It is important to understand the source factors and the movement or transport dynamics of phosphorus.

Phosphorus fertilizer application in crop production

Description

For optimum crop production, an adequate supply of P close to the seed during the first six weeks of growth and an adequate amount of P in the soil for the rest of the season are ideal. Placement of P in-row with cereal and oilseed crops has been the traditional method used for P fertilization in Alberta. Pre-plant banding of P with nitrogen has been found to be a good alternative method of application under certain conditions. However, under conditions of low to medium soil P coupled with low soil temperatures, 'starter' P in the seed row is frequently very beneficial for annual crops.

Description

Phosphorus is an important nutrient for plant growth. In aquatic systems, a lack of phosphorus often limits aquatic plant growth. When phosphorus is used up in fresh water, aquatic plant growth will stop no matter how much nitrogen is available. Conversely, nitrogen limits crop production. Only a small amount of phosphorus (measured in parts per billion) in fresh water can cause algal blooms and aquatic weed growth. Phosphorus is the nutrient that limits plant growth in aquatic ecosystems. Nitrogen is the primary nutrient that limits terrestrial plant growth.
