Kerbernez: nitrogen balance 1992-2005

Map of the nitrogen balance of the plots of the INRA study site in Kerbernez. The nitrogen balance is reported from 1992 to 2005 and is expressed in kg of nitrogen per hectare The vector layer was created from the data and calculations of Laurent RUIZ and from the map of the parcel cut by Samuel Abiven (ABIVEN. S., 2000)Kerbernez地区INRA研究样地地块氮平衡分布图。该数据集的氮平衡统计时段为1992年至2005年，单位为千克氮每公顷。本矢量图层基于Laurent RUIZ的实测数据与计算成果，以及Samuel Abiven于2000年绘制的地块分割图（ABIVEN. S., 2000）制作完成。
