Penggunaan Biochar dan Pupuk Kandang Ayam dengan Asap Cair untuk Memperbaiki Beberapa Sifat Kimia Tanah dan Pertumbuhan Tanaman Jagung ( Zea mays L.) pada Tanah Ultisol Galang

Abstract

The pot research in the screen house examined the utilization of organic materials (biochar and chicken manure) with liquid smoke on the chemical properties of Ultisol soil and the growth of corn plants (Zea mays L.). This research used a factorial randomized block design (RAK) with 2 factors. The first factor is organic material: biochar (20 tonnes/ha), chicken manure (20 tonnes/ha), and a combination of biochar (10 tonnes/ha) with chicken manure (10 tonnes/ha); The second factor is the concentration of liquid smoke: liquid smoke (0%), liquid smoke (1%), and liquid smoke (2%); and has 3 repetitions (blocks). The parameters observed were pH H2O, C-organic, P-available, Al-dd, CEC, plant height, shoot weight, root weight, and P-plant. The results of the research show that the use of organic chicken coop materials is the best in improving soil chemical properties such as soil pH, organic C, reducing Al-dd, and p-available; and plant growth such as plant height, shoot dry weight, root dry weight and P uptake. The best use of liquid smoke is in increasing plant growth. Biochar+chicken manure with liquid smoke has the best interaction in increasing plant height and crown weight.
