DYNAMICS OF SOIL NITROGEN AVAILABILITY INDICES IN A SANDY CLAY LOAM SOIL AMENDED WITH ANIMAL MANURES

Purpose Transformation of nitrogen (N) from different manure sources to available forms to promote food security in context of rising climate change is vital. Effect of manure (types, nutrients, high rates and application time) on soil N transformation requires further investigation. This study evaluated effects of three animal manures on soil N mineralization of sandy clay loam.
