Phosphorus Dynamics for Efficient Nutrient Management in Organic Agriculture

There exists a wide range of observable inefficiencies in phosphorus (P) management in current organic agriculture. This paper’s objective is to increase the understanding of P dynamics in order to increase the P efficiency in organic agriculture. As a result of the nutrient imbalances in organically accepted nutrient sources and the high reactiveness of P, the management of P is challenging. One of the major contributors to the P inefficiencies in organic agriculture is the strong focus on meeting plant nitrogen (N) needs. Considering the growing global trend towards organic agriculture, decreasing P inefficiencies is important for both increasing the future sustainability of farms for the efficient use of P sources and decreasing the environmental impacts of organic farms on concerns such as eutrophication.
