The research of land capability classification survey is held on the area of water capturing (DTA) of Danau Toba. Land capability classification is fulfilled by using scoring methods based on the land unit in DTA of Danau Toba. The scorring of limitation factor of each land unit is held to obtain land capability class. Here are the limitation factors of each land unit: the depth of efectivity land, texture, drainage, permeability, slope, erotion, flood and surface stone.The research outcome shows that there are totally 36 land units which are divided into 8 land capability classes. Land width of the first class is 26.484.59 ha, the second class is 73.422.64 ha, the third class is 32.912.79 ha, the fourth class is 28.442.06 ha, the fifth class is 21.751.94 ha, the sixth class is 2.749.55 ha, the seventh class is 618.26 ha and the eight class is 30.155.78 ha. Keywords: land capability class, land unit, scorring.

The objective of this research was study the role of silicate material and phosphat fertilizer inimproving soil chemical charachteristics and plant growth. Andisols material was taken fromagriculture area with horticulture commodity in Kuta Rakyat Village, Naman Teran Subdistrict,Karo Regency. This research used factorial blocky randomized design with 3 block and 2 factors.The silicate material were consisted of four kind are : B0 (control), B1 (Agrosil), B2 (coarse grass),B3 (straw rice). The treatment of phosphate fertilizer consisted of four levels, namely : F0 (0 ppm P),F1 (100 ppm P), F2 (200 ppm P), and F3 (300 ppm P). Silicate material was incubated for 45 daysand then applied P fertilizer. The plant kept until vegatative phase in green house. The result of thisresearch showed that the affect of material silicate of coarse grass was very good in increasing Puptake,diameter of stem, dry weight root,dry weight crown, and height plant. And then straw rice isvery good in decrease P retention and Agrosil is very good in increase SiO2 available. The effect ofP fertilizer is not significant while the effect of interaction of silicate material and P fertilizer onlysignificant in hight plant.Keywords : Andisols, silicate material, and phosphate

Field research was conducted applied Agrosil as silicate material and Phosphorus fertilizer forpotato plant to determine the changes of chemical characteristics of Andisols and yield of potato.This research used Factorial Blocky Randomized Design with treatment Si dosage 0 kg SiO2/ha(S0), 750 kg SiO2/ha (S1), 1500 kg SiO2/ha (S2), 2250 kg SiO2/ha (S3), and P fertilizer dosage 0 kgP2O5/ha (P0), 90 kg P2O5/ha (P1), 180 kg P2O5/ha (P2), 270 kg P2O5/ha (P3), so there are sixteencombination and three blocks, so there are fourty eight units treatments. This result showed thatapplied Agrosil could increase soil pH, SiO2 available and decrease P retention. Applied Agrosilcould increase weight and amount of class A tuber(> 100 g/tuber) with the best dosage 1500 kgSiO2/ha at S2 treatment. This research useful to solve the problem phosphate available in Andisolsoil.Keywords: Chemical Characteristics of Andisols, Agrosil and Phosphorus Fertilizer, Yield ofPotato(Solanum tuberosum L.).

The aim of this research was to study the biological and chemical characteristics of paddy soilcaused of burning rice straw. This research was conducted in Subdistrict Tanjung Morawa, DistrictDeli Serdang, North Sumatera Province. Sampling was done at the public rice field with strawburning over it and Balai Benih Sari Murni which never burning straw. Soil samples were takenunder the heap of burnt straw in three times, i.e after burning soon (0 week after harvesting), 1 and2 week after harvesting to analyze the number of arthropod an microorganisms, soil colour, texture,pH, C-organic, N-total, P-available, and K-exchangable in The Soil Biology, Soil Chemical andFertility, and Research and Technology Laboratory, Agricultural Faculty of North SumateraUniversity, Medan. The results showed that the soil with straw burning over it has the number ofarthropod and microorganism, C-organic, N-total, and P-available is lower than the unburnt soil. pHand K-exchangeable of the burnt soil is higher than the unburnt soil. In 2 weeks afterburning, the number of arthropod and microorganism, C-organic, and P-available gets recoveryfrom before.

Penelitian yang menguji dua metode pengukuran Aldd, yaitu dengan ekstraktan KCl dan LaCl3 untuk menetapkan kebutuhan kapur di tanah Ultisol. Hasil pengukuran diterapkan pada tanah di rumah kasa menggunakan Rancangan Acak Kelompok (RAK) non faktorial, 7 perlakuan dosis kapur CaCO3 yaitu 0.0 xAldd; 1.0xAldd-KCl; 1.5xAldd-KCl; 2.0xAldd-KCl; 1.0xAldd-LaCl3; 1.5xAldd-LaCl3; 2.0xAldd-LaCl3 dengan 4 ulangan. Kapur diinkubasi selama 14 hari dalam keadaan kapasitas lapang. Tanaman indikator kedelai ditanam hingga fase pertumbuhan vegetatif. Parameter yang diamati adalah pH H2O, pH KCl, tinggi tanaman, volume akar, berat kering tajuk, berat kering akar, dan serapan N, P, K tanaman. Hasil penelitian menunjukkan bahwa peningkatan dosis kapur hanya meningkatkan pH H2O dan pH KCl tanah. Kebutuhan kapur tanah Ultisol lebih tepat ditentukan menggunakan Aldd ekstrak KCl 1 N. Kata Kunci : Aldd, KCl, LaCl3, kapur, Ultisol
