WebSplit fertilizer application if leaching or denitrification losses are a potential problem (almost always for N only). Apply nutrients when leaching or runoff threats are minimal. Reduce tillage. Use cover crops. Include perennial forage crops in rotation. Balance farm imports and exports once crop needs are being met. WebCompared to adjacent control roofs, median volumetric retention was 56%, 66%, and 72%, for the Tamaki 100 mm, 150 mm, and WCC living roofs, respectively. Despite the apparent difference in median %-retention amongst the mini-roofs of differing substrate depths, there was no statistically significant difference (p=0.05) in runoff depth between them.
