The Application of Zeolite and Potassium Fertilizer to Increase The Avaibility of PotassiumNutrient and Soy Growth in Entisols. Suvervised by Hamidah Hanum and Gantar Sitanggang.Theobjective of this research were: 1) determined of zeolite dosage that improved the soil chemistryproperties, 2) determinated zeolite and potassium fertilizer dosage that effected the avaibility ofpotassium and the soy growth in Entisols. The research consisted of two experiment, the first onewas the experiment of zeolite incubation, and second one was the experiment of zeolit andpotasium fertilizer. The design experiment of the first research was completely randomized designand the second one was block randomized design- factorial. The result showed that in the firstexperiment, zeolite wich incubation until 7.5 ton/hectare incerease CEC significanly, but didn’teffect the soil pH and K-exchangable. Besed the second experiment, it was know that theinteraction effect of zeolit and potasium fertilizer aplication increased potassium nutrient the plant,which the best treatment was zeolite aplication 5 ton/ hectare and potasium fertilizer 150 kg/hectare.Key words: : Entisols, Zeolite, KCl, soy growth

The objective of this research are to survey and to map the nutrients which is nitrogen (N),phosphate (P), and potassium (K) and the soil pH of rain fed lowland in Desa Durian KecamatanPantai Labu. The soil analysis was conducted in Research and Technology Laboratory inAgricultural Faculty of North Sumatra University on July – November 2013. The researchconducted the survey grid method semi-detailed lavel with 1 sample each 250 meter observationdensity. For the nutrient the researcher used Khejdhal method for soil total nitrogen, Extraction HCl25% for soil Potential phosphate, extraction 1 N NH4OAc pH 7 for soil potassium exchange, forsoil pH the researcher used electrometric method, and the result will be interpreted on nutrientstatus map. The result showed that total nitrogen is classified into two status, low nitrogen (582,048Ha) and medium nitrogen (167,952 Ha). Potential phosphate is classified into very low status (750Ha). And potassium exchange is classified into three status, medium potassium (137,202 Ha), highpotassium (515,303 Ha) and very high potassium (97,495 Ha). Soil pH classified into aciditytendency.Key Words: Soil survey, nutrient status mapping, rain fed lowland.

Evaluation of Inceptisol soil chemical in Gambir Core Garden in the Sub district of Salak Pakpak Bharat District has been conducted from March 2013 to June 2013. This study aimed to evaluate the soil chemical (pH, N, P, K, CEC, Organic Carbon, Exchangable Aluminuim) based on land position on the Gambir Core Garden of Pakpak Bharat District. The method used in this research is descriptive method by conducting surveys and soil sampling based land position on the top of the hill, hillside and part of the valley. The results show the value of N and Organic Carbon are tends to rise in the valley compared to the top of the hill and the hillside. As for the value of CEC and Exchangable Aluminium are tend to rise on the hillside compared to to the top of the hill and the valley, while the value of pH, P and K are relatively same.Keyword: land position, soil chemical, gambir (Uncaria gambir Roxb.)

This research aims to evaluate the land suitability of coffea (Coffea arabica L.) in Muara Subdistrict of North Tapanuli Utara. This research use survey method From the results of the overlay from the map of soil types, map of topography, and climate, retrieved 3 (three) units of land use map. SPL 1 has a land area of 796 hectares, SPL 2 has a land area of 243 hectares, and SPL 3 has a land area of 619 hectares.With the Matching method, then retrieved the land suitability class actual and potensial class for coffea (Coffea arabica L.) on each of the SPL. At SPL 1 and SPL 2 are actual land suitability class S3 (wa,nr) while the potential land suitability class is S3 (wa) and at SPL 3 is actual land suitability class S3 (wa,nr,eh) while the potential land suitability class is S3 (wa). Potention of land for Arabic coffea in Muara Subdistrict is 1658 Ha.Key words : land suitability, Arabic coffea, Muara Subdistrict
