Abstract

Ultisol sub-optimal acid dry land indicates sick soil, because the organic matter content is low so it requires amelioration so that it can be recovered and become productivity. Amelioration of acid dry land through the application of biochar and compost has been carried out in Tangkit Village, Sungai Gelam District, Muaro Jambi Regency from May to October 2022. The purpose of the study was to determine the improvement of water available which was applied with coconut shell biochar and leuchaena compost, as well as its effect on the growth of maize plants. The research implementation method used a randomized block design with three groups and 10 experimental units. The experimental formula is: a0: without ameliorant + inorganic fertilizer according to full dose the recommendations; a1: biochar 10 tons + compost 5 tons/ha + inorganic fertilizer full dose; a2: biochar 5 tons/ha + compost 10 tons/ha + inorganic fertilizer full dose recommendation; a3: compost 10 tons/ha + inorganic fertilizer 1/2 dose recommendation; a4: 10 ton/ha biochar + inorganic fertilizer ½ dose recommendation; a5: biochar 5 tons/ha + compost 5 tons/ha + inorganic fertilizer 1/2 dose recommendation; a6: biochar 5 tons/ha + compost 5 tons/ha + inorganic fertilizer1/2 dose recommended; a7: compost 10 tons/ha + inorganic fertilizer as ½ dose recommended; a8: 10 tons/ha biochar + inorganic fertilizer full dose recommended; a9: compost 10 tons/ha _ + biochar 10 tons/ha + inorganic fertilizer ½ dose recommendation. The data obtained from this study were analyzed using Anova and continued with Duncan's test. The observed variables were soil water retention at pF1,0, pF2.54, pF 3.1 and pF 4.2. Field water content, field capacity water content, available water and permanent wilting point water content, as well as maize plant growth. The results showed that: (1) ameliorant coconut shell biochar and lauchaena compost increased the availability of water compared to no treatment, either combined or alone; (2) the combination of biochar 5 tons/ha + compost 10 tons/ha is effective in increasing water available compared to treatment at biochar 10 tons/ha + compost 5 tons/ha and compost 10 tons/ha + biochar 10 tons/ha. (3) the ameliorant compost and biochar given increase the growth of maize plants, and can reduce the need for chemical fertilizers by up to 50%.
