Abstract

The research aims to a mapping of nutrient status available phosphate and total phosphate in the Aek Simare Irrigation Area Laguboti District Toba Samosir Regency. This research was conducted at the Testing Laboratory of Agricultural Technology Research Center in North Sumatera Province. Which began in Mey to June 2019. The method used is the Free Grid Survey detailed level survey and analysis of nutrient data available phosphate by Bray I method, total phosphate by acid destruction method, and then interpret to the map nutrient status. The result of research showing that status available phosphate classified by 3 statuses such as medium (3,99 ha), high (44,26 ha), and very high (71,75 ha). Total phosphate classified in 4 nutrient status such as low (0,004 ha), medium (67,37 ha), high (45,316 ha) and very high (7,31 ha). Available phosphate and total phosphate are very related to increasing rice production in the Aek Simare Irrigation Area Laguboti District Toba Samosir Regency, Northern of Sumatra, Indonesia
