BUDGETING PLANT NUTRIENTS FOR OPTIMUM CROP YIELDS
AND SOIL FERTILITY MANAGEMENT

ABSTRACT
A nutrient budget takes into account all the nutrient inputs on a farm and all those removed
from the land. The most obvious source of nutrients in this situation is fertilizer, but this is
only part of the picture. Other inputs come with rainfall, in supplements brought on to the
farm and in effluent - either farm or dairy factory - spread on the land. In addition, nutrients
can be moved around the farm - from an area used for growing silage to the area used to
feed it out, from paddock to raceway, and within paddocks in dung and urine patches. In this
paper, nutrient budget is discussed as a useful management tool that quantifies the amount of
nutrients imported to and exported from a system. Nutrient budget is an important tool for
effective crop yields and soil management. The paper therefore recommends among others
that nutrient budgeting is a way of helping land owners choose and implement best
management practices (BMPs) that will reduce the likelihood of nutrient surpluses, while
maintaining soil productivity. Having a balanced nutrient budget for an agricultural
production will help to avoid unnecessary production costs and greatly reduce pollution
potential from surplus nutrients.
