Development of Fertilizer of Swine Manure Fermentation by Adding Air and Microorganism

Abstract

Research Development of automatic fermentation of manure and automatic microorganisms. The objectives of this research are study and design the development of fermented manure, aerobic manure and automatic microorganism from an automatic fermentor by performance finding of fertilizer of swine manure fermentation by adding air and microorganism and study satisfaction of farmers, people and students on the efficiency of automatic fermented manure and automatic microorganisms. After the dissemination of knowledge about the design of fermented manure and microbial fermentation systems is automated to control temperature, humidity and air. The size of the structure width x length x height is 216 cm x 290 cm x 153 cm and fertilizer capacity 250 kg. This research uses 200 kg of pig manure mixed with other fertilizers.

It controls the perform by Microcontroller using to set the cycle. The set up the system after the fertilizer every 7 days, 36 minutes per each for 35 days.

The results of comparing between the performance of manure compost from natural fermentation of farmers and fermentation using fertilizer of swine manure fermentation by adding air and microorganism. It was found that the natural fermentation of farmers takes more than 2 months. The fermentation of the pigs mixed with the LDD1 Microbial Activator by fertilizer of swine manure fermentation adding air and microorganism found that after 7 days, there are automatic adding air and  LDD2 Microbial Activator were used to compound it on the fertilizer manure. Aeration will impact to temperature decreasing. The Microbial loading increases average moisture content 63.8% per day per cycle 7 days for 5 times, total 35 days. The researchers found that the compost producted had a light, crumbly, dark brown. The smell of pigs is reduced. The pre-fermentation result was 1.33% urea nitrogen and after 35 days fermentation found urea nitrogen was reduced to 1.26%
