The Utilization Of Some Of Biochar To Retain N-Total In Inceptisols

Abstract

Nitrogen is very important nutrient growth of plant but eassy lost from soil. The aim of this researc to get the best biochar feedstock in maintaining N-total in the Inceptisol soil. Theresearch was carried out in the laboratory using the method of experiment. This research was carried out with complete randomized design non factorial with the treatment without biochar (controls), and 4 types of biochar from palm empty fruit bunches, rice straw, rice husks and wood, is repeated four times. The observed parameters are pH H2O,CEC, & Ntotal ground. The results showed that the four types of biochar can increase the pH H2O, CEC, N-total ground. Loss of Nutrient N decreased significantly due to the granting of biochar palm empty fruit bunches. Absorption capacity of biochar to reduce leaching of N in the soil of inseptisol sorted from largest to smallest is biochar palm empty fruit bunches, rice husk, rice straw and wood. ABSTRAKUnsur hara nitrogen sangat penting keberadaannya di dalam tanah, oleh karena itu penelitian ini bertujuan untuk mendapatkan bahan baku biochar terbaik dalam mempertahankan N-total di tanah Inceptisol. Penelitian dilaksanakan di laboratorium menggunakan metode eksperimen. Penelitian ini dilaksanakan dengan rancangan acak lengkap (RAL) non faktorial dengan perlakuan tanpa biochar (kontrol), dan 4 jenis biochar dari bahan TKKS, jerami padi, sekam padi dan kayu, diulang sebanyak 4 kali. Parameter yang diamati adalah pH H2O, KTK,&Ntotal tanah. Hasil penelitian menunjukkan bahwa keempat jenis biochar mampu meningkatkan pH H2O, KTK, N-total tanah. Kehilangan Hara N menurun secara nyata akibat pemberian biochar TKKS. Kapasitas serapan biochar untuk mengurangi pencucian N di tanah inseptisol diurutkan dari yang terbesar hingga terkecil adalah biochar TKKS, biochar jerami padi, sekam padi dan kayu.

Exploration and macroscopic characterization of microbiomes (fungi and bacteria) on anthracnose-Infected chili plants in lowlands fields of Deli Serdang North Sumatra

“…Conidia are hyaline or brightly coloured. Most of the conidia are ovoid and form long chains [20] Isolates L1SDCJ5, L1SBACJ1, L2SBCJ3 showed that the fungus has upright conidiophores, many branches, short and thick fialids, conidia are round to ovoid in shape and are single-celled, somewhat conical in shape, can form chlamydospores, is the fungus Trichoderma sp. Trichoderma sp has conidiophores that are highly branched and upright.…”

Optimising Water Management in Drylands to Increase Crop Productivity and Anticipate Climate Change in Indonesia

“…Furthermore, large quantities of rain and runoff can anticipate El Nino climate anomalies or extend the planting period to the end of the rainy season [72][73][74]. Channel reservoirs as irrigation sources have been developed in several dryland areas, such as West Java, Central Java, Yogyakarta Special Region, East Java, Southeast Sulawesi, and South Sulawesi [65,[75][76][77][78][79][80][81][82][83][84][85][86].

Results show that dryland productivity can potentially be increased if (1) the problem of water availability fluctuations can be minimised, (2) the water storage capacity of the watershed can be maximised naturally and artificially, and (3) the efficiency of water use and the commodity cultivated can be improved and optimised [78].…”

“…The channel reservoir is a technique for harvesting rainwater and runoff by blocking the flow of water into a stream, channel, or ditch and keeping it in storage as supplemental irrigation water during the dry season. In addition, channel reservoirs also reduce water flow velocity, reduce peak discharge, and extend response time in a watershed, and reduce sedimentation in downstream areas.Channel reservoirs as irrigation sources have been developed in several dryland areas, such as West Java, Central Java, Yogyakarta Special Region, East Java, Southeast Sulawesi, and South Sulawesi[65,[75][76][77][78][79][80][81][82][83][84][85][86].
