This study aimed to determine the diverification of the amendment to the base saturation and production of sweet orange. This research was conducted in plantation citrus Talimbaru Village Barusjahe District Regency of Karo with plant age of ± five years and soil analysis at the Laboratory of PT. Socfin Indonesia and Laboratory Research and Technology Faculty of Agriculture, University of North Sumatra. This experiment using a Nonfaktorial Randomized Block Design (RAK) which consists of 5 treatments, namely B0 = Without Amendment (control), BP1 = Cow Manure (8,07 kg/plant), BP2 = Chicken Manure (8.15 kg/plant) , BA1 = Powder Ash (8,11 kg/plant), and BA2 = Shells Palm Oil (8.15 kg/plant) three replications. This research was conducted for 4 months. The parameters were measured soil pH, organic-C, P-available, N-total, CEC, K-exchange, Ca-exchange, Mg-exchange, Na-exchange, base saturation, and production citrus. The results showed that application of amendment materials palm shells and cow manure can improve base saturation so that citrus fruits production increased. Cow manure amendment supply bases Ca and Mg while shells palm oil supply base K in the soil. All amendment increased pH and soil organic C.Keywords : Cow Manure, Chicken Manure, Powder Ash, Shells Palm Oil, Nutrient Retention, CitrusThis study aimed to determine the diverification of the amendment to the base saturation and production of sweet orange.

Population of soil mesofauna is strongly influenced by the availability of food sources in their environment. Food sources may include various types of organic materials. This research aimed to determine the effect of types and technique application of organic materials on weed circle towards the population of soil mesofauna. This research was conducted in Indonesia Oil Palm Research Institute (IOPRI) plantations Aek Pancur, Tanjung Morawa. This research was use factorial randomized block design. The first factor was the types of organic material, i.e. without organic material, litter, Empty Fruit Bunch (EFB), litter + T. harzianum and EFB + T. harzianum and the second factor was the technique application of organic materials i.e. spread in palm circle, put around the stand of palm and put on the threshold of palm circle. The results showed that in week 2, type of organic materials, technique application and both interaction was not affect soil mesofauna population, but in week 4, 6 8 and 12 type of EFB, technique application spread in palm circle and both interaction could increase the population of soil mesofauna. The highest population was on treatment B2A1 in week 12 (4106 ind m-2).

Effect of Some Ameliorants on Chemical Properties Of Toba Highland Peat and Growth of Rice (Oryza sativa L.) Berkat Julianto Banjarnahor; Sarifuddin Sarifuddin; Kemala Sari Lubis

ABSTRACT The aim of this study to know effect of some ameliorants by toba plateau peat’s chemical characteristic for growth and production Ciherang. The study was conducted at greenhouse of Faculty of Agriculture, University of Sumatera Utara and analysed at PT.Socfin Indonesia and Laboratories Research and Technology. This research used randomized block design non factorial with eight treatments there were G0 (control), G1 (volcanic ash 250 g / pot), G2 steel slag 50 g / pot), G3 (seawater 250 ml / pot), G4 (volcanic ash 250 g + steel slag 50 g / pot), G5 (volcanic ash 250 g + seawater 250 ml / pot), G6 (steel slag 50 g + seawater 250 ml / pot), G7 (volcanic ash 250 g + steel slag 50 g + sea water 250 ml / pot) with three replications. The results showed ameliorant steel slag 50 g increased the soil up to pH 4:35, combinations volcanic ash 250 g and the steel slag 50 g increased the electrical conductivity up to 0,194 mmhos/cm and combination of volcanic ash 250 g and the 50 g of steel slag increased rice growth there are toba highland peat 107,3 cm in height, 25 clumps in number of vegetatif and generatif tillers and reduce the percentage of empty grain up to 78.73%, %, and aplication combination ameliorant volcanic ash 250 g with 50 g of steel slag as well as sea water 250 ml increase the production of rice plants / pots and grain weight 1000 grain with the value of each 24.12 grams and 21.47 grams Top of Form Keywords: Highland Toba peat, Rice Ciherang variety, Seawater, Steel slag, Volcanic ash
