One effort to meet the needs of rice is by planting upland rice in dry land. Ultisol is the most extensive dry land in Indonesia. The yield of upland rice in Ultisol is very low, this is caused by various problems including acid reaction, high Al saturation and P fixation, availability of macro nutrients (N, P, K, Ca, Mg), low micro nutrients (Mo). Rice husk ash and natural phosphate can be used to increase pH and nutrient availability. The purpose of study was to study the effect of the interaction of rice husk ash and natural phosphate in increasing the growth and yield of upland rice ( Oryza sativa L.) on Ultisol medium. The study was conducted at the Faculty of Agriculture greenhouse, University of Riau from March to July 2019. The research was an experiment in the form of a 4x3 factorial using a completely randomized design. The first factor consists of four levels of rice husk ash (0.0; 1.5; 3.0; and 4.5 tons ha -1 ), the second factor of natural phosphate consists of 3 levels (0, 25 and 40 kg P 2 O 5 ha -1 ), each repeated three times. The results showed the interaction between rice husk ash with a dose of 1.5 tons ha -1 and natural phosphate with a dose of 25 kg P 2 O 5 ha -1 increased plant height, number of productive tillers, panicle length, number of paddy grains with pan, paddy grains and dry grain weight milled compared without rice husk ash and natural phosphate, each of these parameters tends to increase higher at the highest dose (4.5 tons ha -1 rice husk ash and 40 kg P 2 O 5 ha -1 natural phosphate).","PeriodicalId":55827,"journal":{"name":"Jurnal Agroekoteknologi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41812727","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the specific forms of Al, Fe, and Mn inside the soil are very important to know because they are related to soil fertility. The purpose of this study was to determine the distribution of the Al fraction on the acid soil profile of dry land in Lebak Regency, Banten Province. This research was conducted from April to June 2019 in Maja District, Lebak Regency, Banten. The research was descriptive explorative with intentional sampling for special purposive sampling. The soil was tested with a main parameter using single extraction for Al Fractionation. The results showed that the Al fraction in amorphous form (Al-o) was more dominant than Al in dissolved form (Al-dd) in all horizon layers (0-120 cm). Moreover, the Al fraction in organic amorphous form (Al-p) was also more dominant than Al in the inorganic amorphous form (Al-po) at horizon layer of 0-15 cm, while at horizon laeyer of 15-120 cm the Al-po form was higher than Al-p.
