PERBAIKAN KAPASITAS PEGANG AIR DAN KAPASITAS TUKAR KATION TANAH BERPASIR DENGAN APLIKASI PUPUK KANDANG PADA ULTISOL SIMALINGKAR

Abstract: Research took place in University of HKBP Nommensen, Faculty of Agriculture Research Greenhouse in Simalingkar, Medan, Indonesia. Hypothesized that the application of manure as a singgle factor could increasing the soil water holding capcity and soil cation exchange capacity.Research designed with Complete Randomize Design,the treatment replicated by four times.Every parameter that effected significantly will be continued analized with Duncan’s Multiple Range Test. For observation had made by measures of soil water holding capcity and soil cation exchange capacity.The concluding of the research can be explain thatThe Effects of manure application on sandy soil after 30 days of incubation at rate of application equal with 20 t/ha has significantly increased soil water holding capacity only at 72 hours after saturation. The Effects of manure application on sandy soil after 15 as well as 30 days of incubation at all rate of application has not significantly effected cation exchange capacity.
Keys words: manure, water holding capacity, and cation exchange capacity
