Abstract

Penelitian rumah kasa bertujuan untuk menentukan bahan baku biochar yang terbaik untuk memperbaiki sifat kimia tanah Ultisol dan pertumbuhan tanaman jagung. Penelitian menggunakan rancangan acak kelompok non faktorial dengan 5 perlakuan yaitu kontrol, biochar jerami padi, biochar TKKS, biochar kulit durian, dan biochar kotoran sapi, dengan dosis 50 g/pot dan 4 blok. Parameter yang diukur adalah pH, C-organik, N-total, P-tersedia, K tukar, umur berbunga, tinggi tanaman, bobot kering tajuk, bobot kering akar, serapan N, P, dan K. Hasil penelitian menunjukkan pemberian biochar mampu meningkatkan pH tanah, C-organik, N-total, P-tersedia, K tukar , umur berbunga, tinggi tanaman, bobot kering tajuk, serapan N dan P akan tetapi tidak berpengaruh dalam meningkatkan serapan K dan bobot kering akar tanaman jagung. Biochar kotoran sapi lebih baik dibandingkan biochar lainnya dalam meningkatkan sifat kimia tanah Ultisol dan pertumbuhan tanaman jagung.

Abstract

Penelitian survei bertujuan untuk mengklasifikasikan tanah pada satuan lahan volkan tua di Sumatera Utara menurut klasifikasi taksonomi tanah dan klasifikasi nasional. Penelitian dilakukan pada dua areal lahan, yaitu kaki lereng Gunung Sipiso-piso dan Gunung Simbolon. Pada masing-masing areal dibuat profil pewakil untuk diamati morfologinya kemudian diambil sampel tanah dari setiap horizon untuk dianalisis bulk densiti, tekstur tanah, C-organik, Retensi P,  Al dan Fe ekstrak oksalat di Laboratorium Riset dan Teknologi, Fakultas Pertanian, Universitas Sumatera Utara. Hasil penelitian menunjukkan bahwa tanah pada satuan lahan volkan tua yang berada di kaki lereng Gunung Sipiso-piso memiliki BD > 0.9 g/cm-3, retensi P > 85%, kadar Alo +1/2 Feo > 2%, sehingga diklasifikasikan menurut taksonomi tanah (Ultic Hapludand) dan klasifikasi nasional (Andosol Distrik). Sedangkan tanah pada lahan volkan tua yang terdapat di kaki lereng Gunung Simbolon memiliki  BD > 0.9 g/cm-3, retensi P < 85%, kadar Alo +1/2 Feo < 2%, sehingga diklasifikasikan berdasarkan taksonomi tanah (Andic Dystrudept) dan klasifikasi nasional (Kambisol Kromik).

Abstract

Green house study to increase growth of corn plants with application human urine fermentation as liquid organic fertilizer in Inceptisols Kwala Bekala. Research using randomized block non factorial design with 5 levels of dosage treatmenthuman urine fermentation that is:  0 mL/pot (P0), 25 mL/pot (P1), 50 mL/pot (P2), 75 mL/pot (P3) and100 mL/pot (P4) with 5 replications. Parameter that measured are soil pH, organic C, N-total,  P-available, K-exchangeable, plant height, root dry weight, shoot dry weight, N, P and K uptake in Laboratory. Result of this research showed that application human urine fermentation can improve soil pH, organic C, N-total, P-available, K-exchangaeble, plant Height, root and shoot dry weight, and uptake N, P, K  growth of corn plants. Best human urine fermentation dose on this research is 75 mL/pot (P3). Keywords: Human urine fermentation, Inceptisols Kwala Bekala, Nutrient, Organic fertilizer.

Abstract

This study aimed to analyze and determine the chemical properties of paddy soil in the Sunggal sub district so that it can be determined Sunggal paddy soil fertilizer recommendations. Research using surveys with sampling techniques stratified random sampling based on the type of rice fields Rainfed and Irrigation and data analysis pH with methods Elektrometri, C organic method of Walkley and Black, the N total with methods Kjeldhal, P available by the method of Bray II, cations base (K+,Na+,Ca2+,Mg2+)by the method of extraction of NH4OAc 1N pH 7, CEC with NH4OAc 1 N pH 7 extraction method and Base Saturation with the calculations. Results of research on the soil for rainfed and irrigation showed that the pH of dominant soil slightly acid, organic C dominant low, N total is low, P available predominantly very low, K exchange dominant low, Ca exchange is low, Mg exchange the dominant medium, Na exchange low dominant, dominant CEC being, Base Saturation is very low dominant. Soil fertility status of rainfed and irrigation is relatively very low to low, except in rainfed Puji Mulyo village were moderate due to high organic C.
