Abstract

Abstrak. Biochar merupakan padatan berupa arang yang kaya karbon (C) melalui proses pembakaran tidak sempurna dengan minimum oksigen (pyrolisis). Penambahan bahan organik dapat mempercepat proses pemulihan kualitas lahan serta meningkatkan kekuatan tanah memegang air sehingga kandungan unsur hara juga meningkat. Pemanfaatan kompos berpengaruh terhadap pasokan hara tanah, perubahan sifat fisik, biologi, dan kimia tanah, karena syarat tanah sebagai media tumbuh tanaman membutuhkan kondisi fisik dan kimia yang baik. Aplikasi biochar dan kompos dilakukan untuk meningkatkan kesuburan dan ketersediaan air tanah untuk memenuhi kebutuhan tanaman.Pada penelitian ini digunakan tanaman jagung (Zea mays L) sebagai indikator tanaman. Penelitian ini menggunakan Rancangan Acak Kelompok (RAK) dengan pola Non Faktorial terdiri dari kombinasi biochar dan kompos limbah pertanian dengan 9 perlakuandan 3 kali ulangan, maka didapatkan 27 bedengan percobaan. Hasil di lapangan didapatkan pemberian biochar dan kompos limbah pertanian tidak berpengaruh terhadap perbaikan sifat fisika tanah pada lahan kering diduga karena sifat fisika yang sulit berubahdalam waktu yang singkat, namun pemberian biochar dan kompos limbah pertanian dapat meningkatkan atau berpengaruh terhadap pertumbuhan serta hasil tanaman jagung yang mana nilai tertinggi terdapat pada perlakuan A8 (15 ton ha -1 biochar dan 20 ton ha -1 kompos imbah pertanian) hal ini diduga pada dosis tersebut pemberian kompos menyumbangkan unsur hara yang cukup bagi tanaman.Utilization of Biochar and Agricultural Waste Compost to Improve Soil Physical Properties, Growth and Yield of Corn on Dry LandAbstract. Biochar is a solid in the form of charcoal rich in carbon (C) through an incomplete combustion process with a minimum of oxygen (pyrolysis). The addition of organic matter can accelerate the process of restoring land quality and increase the strength of the soil to hold water so that the nutrient content also increases. The use of compost affects the supply of soil nutrients, changes in the physical, biological, and chemical properties of the soil, because the soil requirements as a medium for plant growth require good physical and chemical conditions. Applications of biochar and compost are carried out to increase fertility and availability of groundwater to meet plant needs. In this study, maize (Zea mays L) was used as plant indicator. This study used a Randomized Block Design (RBK) with a non-factorial pattern consisting of a combination of biochar and agricultural waste compost with 9 treatments and 3 replications, so 27 experimental beds were obtained. The results in the field showed that the application of biochar and agricultural waste compost did not affect the improvement of the physical properties of the soil on dry land, presumably due to the physical properties that were difficult to change in a short time, but the application of biochar and agricultural waste compost could increase or affect the growth and yield of maize plants. where the highest value was found in the A 8 treatment (15 tons ha -1 biochar and 20 tons ha -1 agricultural waste compost).
