NUTRIENT BALANCES IN FIELD VEGETABLE PRODUCTION SYSTEMS

Acta Horticulturae, 2003
In this review paper an overview of the nitrogen (N) and phosphorus (P) cycles in agricultural systems is presented. The information summarized provides general information on the important processes involved as they relate to losses from agricultural systems.

Balancing act: Understanding nutrient interactions

World Journal of Biology Pharmacy and Health Sciences
Nutrient interactions refer to the dynamic relationship between various nutrients, including minerals, vitamins, amino acids, and fatty acids, for proper functioning. An excess or deficiency of one nutrient can affect the requirements for many others, and increasing or decreasing a deficient nutrient may require an increase in other nutrients.

Ecosystem Nutrient Balance and Dynamics

2000
Many attempts at balancing ecosystem-level nutrient budgets have been made in the past few decades using a variety of approaches, and for a variety of different purposes. Relatively simple mass balance equations have been used at the level of the watershed that might comprise single forested ecosystems (e.g., Binkley et al. 1982; Stohlgren et al. 1991;

Balancing nutrient supply and nutrient requirements in grazing sheep

Small Ruminant Research, 2010
Abstract Attempting to achieve a balance between the supply of and requirements for the major nutrients implies that demands for major nutrients can be adequately quantified, that the nutritive value of the consumed diet can be described in similar terms and that the diet actually consumed by the grazing sheep can be estimated, or at least predicted,

Efficient use of nutrients: an art of balancing

Field Crops Research, 1998
Abstract Nutrient-use efficiency is conceived as the product of uptake efficiency, i.e., the ratio of actual uptake to potential supply, and utilization efficiency, i.e., the ratio of yield to actual uptake. Both depend on the availability of the nutrient in relation to other growth factors, and require N, P and K perfectly in balance to reach their ...

Nutrient Cycles and Mass Balances

2013
Chemical elements without a prominent gaseous phase at normal biologic temperature, such as calcium, magnesium, and potassium, have what is referred to as a sedimentary biogeochemical cycle (Odum 1959). That is, flux and cycling are affected primarily by hydrologic factors (including dissolution, erosion, and sedimentation), landslides, vulcanism, and ...
