NITROGEN FORMS IN THREE KENYAN SOILS ANDOSOLS, LUVISOLS AND FERRALSOLS
International Journal for Innovation Education and Research, 2016 The nitrogen cycle in soil is an integral part of the overall cycle of N in nature. The primary source of N is the atmosphere where the strongly bonded gas molecule N is predominately gas (78.08%). Total N content in soils ranges from 0.02% in the subsoil and more than 2.5% in peats; ploughed layers of most cultivated soils contain between 0.06 and 0.5%
