Biochar Production from Stubble and Rice Straw for Water Holding in Soil.

Abstract

This research aims to study the production of biochar from stubble and rice straw applied to the water in the soil. The production of charcoal burning in steel 200-liter tank has a maximum volume of charcoal, Then activated biochar, who has to test its ability to hold water in the soil. Using sand instead of soil and biochar at a ratio of 0 , 5, 10, 15 and 20 g. The results showed that biochar Bright tasty at the steel 200-liter tank liters is equal to 45% and test its ability to hold water in the soil is found when using biochar for water holding capacity with the sand and biochar in various quantities equal to 32 , 50 , 80, 88 and 99% respectively. If the soil through a sieve No. 100 is 10%, water holding capacity equal to 80% and retain moisture is 104 hours.
