Abstract

Maize is the second main food commodity in the Indonesian economic system. The self-sufficiency was achieved in 2017, however the nation's corn production to decrease and import value in 2018 and 2019 increased by 60.98% and 25.49% or about 1.15 million tons and 293,210 tons. The projection of cornproduction until 2024 will increase by about 24.04 - 24.98 million tonsof dry peel with a growth rate of about 2.05%. The development of maize in the tidal swampland by the extensification of the planting area is very possible, particularly on the C, C/D, and D overflow type land that is about 3.36 million hectares wide. According to the growth rate, the planting area increasedby about 75,000 ha would contribute about 396.750 tons/year to the nation's production. One of the planting methods that could be applied for maize plants to increase productivity and corn production is the Zig-Zag System. The zig-zag system could increase plant population by around 60-80% and yield 30-40% per hectare. The development of hybrid variety with the Zig-Zag system by the 75 x 25 x 12.5 cm spacing 100-hectare wides in the acid sulfate land conducted in  South Kalimantan, could be increasing the corn productivity achieved 14 ton/ha dry peel with 15% water content. The development of maize with planting methods the zig-zag systems in the tidal swampland very prospectively to supporting an increase of nation corn production.

Abstract

Acid sulfate soils are of poor quality and characterized by extreme acidity, nutrient deficiency, and high Al and Fe toxicity. Developing soil amendments from local resources is crucial to reduce input costs. This study investigated the effect of the integrated soil amendments (biochar, compost, and lime) on corn growth and the acid sulfate soil quality. Using randomized block design, this study tested nine type soil amendments, namely A (100% rice husk ash), B (100% rice husk biochar), C (100% compost), D (100% dolomite), H (100% humate), ACD (30% rice husk ash + 30% compost + 40% dolomite), BCD (30% rice husk biochar + 30% compost + 40% dolomite), AHD (30% rice husk ash + 30% humate + 40% dolomite), BHD (30% rice husk biochar+30% humate+40% dolomite), and control (no amendment). The application of soil amendments significantly increased soil pH (31%), available P (310%), reduced exchangeable Al (19%), and increased corn growth (163%). The BCD amendment type increased available phosphorus from 10 to 43 mg kg-1, reduced exchangeable Al from 3.45 to 2.01 cmol(+) kg-1, and enhanced corn growth and leaves' P level. Integrating rice husk biochar and compost could reduce the need for agricultural lime, improve acid sulfate soil quality, and enhance land productivity. This combination has the potential to be an effective soil amendment for degraded acid sulfate soils, thereby further boosting land productivity and promoting agricultural sustainability.
