The objective of this research is to study the effect of empty palm oil bunch compost (EPOBC) andthe application of phosphorus fertilizer of SP-36 on chemical characteristic of acid sulphate soils,rice growth and production (Oryza sativa L.). This study used a randomized block design factorial,with 2 factors: factor 1: compost EPOBC treatment (B) which consist of: B0 = 0 ton ha-1 (0g EPOBC/pot) ; B1 = 10 ton ha-1 (40 g EPOBC/pot); B2 = 20 ton ha-1 (80 g EPOBC/pot);B3 = 30 ton ha-1 (120 g EPOBC/pot) . Factor 2: fertilizer phosphorus (P) which consist of : P0 = 0kg SP-36 ha-1 (0 g SP-36/pot); P1 = ½ dose (1/2 x 135), advice equal with 0,27 g SP-36/pot; P2 = 1,0dose (1 x 135), advice equal with 0,54 g SP-36/pot; P3 = 1 ½ dose (1 1/2 x 135), advice equal with0,81 g SP-36/pot. The results of this research showed that EPOBC treatment significantly affectedsoil pH and Fe2+ reduction, C-organic, seed total and dry weight of rice. While the application ofSP-36 fertilizer non significantly affected P-available and height of plants. Combination betweenEPOBC and fertilizer SP-36 significantly increased seed total and dry weight of rice.Key words: acid sulphate soil, EPOBC, SP-36,rice

ABSTRACTThe objective of this research was to study the effect of rice straw compost and the application ofphosphorus fertilizer of SP-36 on chemical characteristic of acid sulphate soils, rice growth andproduction (Oryza sativa L). This research was conducted in greenhouse agricultural departments,Universities Northen Sumatera, Medan. This study used a randomized block design factorial, with2 factors : factor 1 : rice straw compost treatment (J) wich consist of : J0 = 0 ton ha-1(0 g straw/pot); J1 = 10 ton ha-1 (40 g straw/pot); J2 = 20 ton ha-1 (80 g straw /pot); J3 = 30 ton ha-1(120 g straw/pot). Faktor 2 : fertilizer phosphorus (P) which consist of : P0 = 0 kg SP-36 ha-1(0 g SP-36/pot); P1 = 0.5 dose (0.5 x 135 kg/ha), advice equal with 0,27 g SP-36/pot;P2 = 1,0 dose (1 x 135 kg/ha), advice equal with 0,54 g SP-36/pot; P3 = 1.5 dose (1.5 x 135 kg/ha),advice equal with 0,81 g SP-36/pot. This results of the research showed that rice straw composttreatment significantly affected C-organic, Fe2+ reduction, the maximum seedlings, dry weight ofroot. While the application of SP-36 fertilizer significantly affected the maximum seedlings.Combination of rice straw compost and fertilizer SP-36 significantly increased the maximumseedlings.Key words: acidic sulphate soil, straw compost, SP-36, rice

ABSTRACTAn experimental research was done to measure the nutrient use efficiency (NUE) of Phosphorus (P)in Andisols and Ultisols. The research was conducted in Screenhouse and Research and TechnologyLaboratory, Faculty of Agriculture, University of North Sumatera from September 2012 until July2013. It was arranged in Non-factorial Randomized Block Design with 6 dosages of PhosphorusFertilizer (SP-36) in Andisols and Ultisols (0; 0,4; 0,8; 1,2; 1,6; and 2,0 grams of SP-36/plant). The intertreatments effects were analyzed using DMRT.The results showed thatRecovery Efficiency (RE) and Agronomic Efficiency (AE) in Ultisols are higher than in Andisols,meanwhile Physiological Efficiency (PE) in Andisols is higher. RE and AE were decreased as aresult of increasing dosage of SP-36 meanwhile PE was increased. The best treatment in Andisolsand Ultisols is 0,8 grams SP-36/plant. In Andisols, productivity of maize at that treatment is 109,23grams/plant (7,28 tons/Ha); RE (11,55%); PE (576,67 grams dry weight cob of maize /g P2O5);and AE (66,68 grams dry weight cob of maize /g P2O5). In Ultisols, productivity of maize at thattreatment is 67,30 grams/plant (4,48 tons/Ha); RE (15,16%); PE (589,29 grams dry weight cob ofmaize /g P2O5); and AE (88,94 grams dry weight cob of maize /g P2O5)Key words : Nutrient Use Efficiency (NUE), phosphorus (P), andisols, and ultisols

The research was conducted to examine P-available of paddy soil potential of acid sulfate withBray II, Truog and Olsen. The research held in Seed Technology Laboratory (seeding), green houseand also in Research and Technology Laboratory Agriculture Faculty University of SumateraUtara. The research used non factorial Randomized Block Design with 3 repetition, which as mainfactor is the giving of Natural Phosphate with 9 kind of dosages, that is: 0, 50, 100, 150, 200, 250,300, 350, and 400 ppm. The giving of Natural Phosphate was significant to the phosphorus sorptionwith the best dosage is P7 (350 ppm) and pH with the best dosage is P8 (400 ppm). The examiningof P-available from the giving of natural phosphate results that the value of P-available by usingBray II and Truog method was higher than the value of P-available by using Olsen method, andthere is no appropriate value of P critical limit for each method.Keywords: P-Available, acid sulfate soil, potential

This research aims to find out the influence of application organic matter and rock phosphate toimprove soil chemical characteristic, growth and production of rice plant in acid sulphate soils, it isrelated to acid sulphate soils case, such as low pH, high iron (Fe2+) making less production. It isconducted in Faculty of Agriculturegreenhouses, University of North Sumatra, using a randomizedblock design factorial, with 2 factors; organic matter (B), B0 =(0 g /pot); B1 = (40 g straw /pot); B2= (80 g straw/pot); B3 = (40 g cow’s manure/pot); B4 = (80 g cow’s manure/pot); B5 = (26,7 gstraw + 53,3 g cow’s manure/pot) and rock phosphate (P), P0 = (0 g /pot); P1 = (0,64 g rockphosphate /pot); P2 = (1,28 g rock phosphate /pot). The measured parameters were pH, C-organic,P-avaliable, Fe2+, plant height, maximum seedlings and weight of dried grains. The results showedthat organic matter application significantly affected in increasing pH, P-avaliable,maximumseedlings, plant height, weight of dried grains and decreasing Fe2+at final vegetative phase. Rockphosphate application significantly affected in increasing pH, P-avaliable, weight of dried grainsand decreasing Fe2+at final vegetative phase. Combination of the two factors significantly affectedin increasing pH, P-avaliable, maximum seedlings, plant height, weight of dried grains anddecreasing Fe2+at final vegetative phase.Key words: acid sulphate soils, rice plant, organic matter, rock phosphate

This research aims to know the difference of level of C-Organic, N and P in Humitropepts atdifferent altitudes in sub-district of Lintong Nihuta. The study done in sub-district of LintongNihuta at altitudes of 1300 to > 1500 meters above sea level in September – November 2013. Theresults showed that the C-Organic and N-total of Humitropepts sub-district of Lintong Nihuta tendto rise along with the added altitude and tend to decrease when increasing the depth of the soil. Incontrast, P-available tends to decreases with increasing altitude and the moment we get tend toincrease the depth of the soil.Key words: c-organic, nitrogen, phosphate, humitropepts, altitude.
