I am researching on the environmental impacts of soilless strawberries, cultivated in coconut fiber. However, we ere not able to gather experimental data on field. Hence, to estimate emissions we need to know how much N and P is retained (on average) in the substrate, and, possibly, also the average percentage of Nitrogen and Phosphorus present in the drainage.
Any insights or references to relevant studies would be greatly appreciated.
The average retention of nutrients in coconut fiber (coir) for strawberry cultivation varies, but typical ranges are:
Nitrogen (N): 20-30% retention
Phosphorus (P): 30-45% retention
These percentages can fluctuate based on factors like irrigation practices, fertilizer formulations, and the specific properties of the coconut fiber used. It's important to note that these are general estimates, and actual retention rates may differ in specific growing conditions.
