SPARTAN NUTRIENT CYCLE CARD
a guide for dairy farm nutrient flow management
The Spartan Nutrient Cycle Card is
provided to help you manage the flow
and recycling of nitrogen (N),
phosphorus (P), and potassium (K)
through your dairy farm. By balancing
the flow of nutrient imports and exports
across your farm boundary, efficient
nutrient use can be maximized and
accumulation of nutrients in soil or risk of
nutrient loss can be minimized.
Symbols on the Cycle
A point on the farm where nutrients are realized, stored, or
transferred and where there is a potential for nutrient loss.
Critical Control Points requiring efforts to optimize nutrient use.
Each CCP has a corresponding checklist on the card reverse.
Export of nutrients, products, or other matter across farm
boundary and off the farm.
Import of nutrients, product, or other matter across farm
boundary on to the farm.
Natural movement of nutrients through the farm cycle, such
as from rations to animals.
Take home points
•Valuable nutrients N, P, and K flow through a dairy farm
and across its boundaries.
•There are 4 points in the farm cycle at which controlling
nutrient flow is critical.
•Following the guidelines outlined on the Nutrient Cycle
Card can help balance flow of nutrients, maximize
efficiency, and minimize accumulation of nutrients in
soil and risk of nutrient loss.
