Abstract

The application of Crotalaria mucronata Desv. And Crotalaria juncea L. liquid green manure in Ultisol Soil media causes soil fertility to be better and more fertile. Ultisol soil, known as Red-Yellow Podzolic, has minimal nutrients, so plants are less developed and grow in the Soil. Crotalaria mucronata Desv. Crotalaria juncea L. is a plant that can provide nutrients to the Soil in an organic form that can be applied to nutrients fertilizer 12.12.17.2, which will make soil nutrients more available and make plants thrive and develop and produce production. This research was conducted at the Soil and Soil Fertility Laboratory Research Practice Farm, University of Sumatera Utara, Medan. This research used a Randomized Group Design (RGD). The results showed that the application of liquid green manure Crotalaria mucronata Desv. And Crotalaria juncea L. as much as 300 ml. polybag^-1 and fertilizer 12.12.17.2 as much as 10 g. polybag^-1 was the highest treatment to improve Ultisol Soil fertility both in Soil Chemistry and Physics.
