The results herein indicate that the application of 6 to 9 t zeolite ha–1 were considerably more effective than the zeolite-free treatment for the most quantitative canola forage traits. Although the N concentration in forage decreased with a concurrent zeolite application, the forage yield quality and quantity did not decline. Furthermore, the application of high N levels (180 and 270 kg N ha–1) significantly enhanced the qualitative and quantitative canola forage traits. A combined application of zeolite and chemical N for canola production in a poor sandy soil is recommended to ensure an acceptable forage yield (agronomic importance) and for soil protection from excess N leaching loss (economical and environmental importance). However, to precisely determine the way that zeolite performs, more research (evaluating different crop and
cultivars as well as integrated application of zeolite with other minerals and organic N sources) is necessary.
