Abstract: The Bio Super Vegetable Gardens (BSVG) obtains the highest bio-productivity of some cash vegetables crops per unit area by planting them utilizing a friendly environment technology, through the addition of organic waste to the soil, e.g. plant wastes (rice straw and compost) and animal wastes (chicken manure), Bentonite or Biochar, Mixture of natural minerals, biopolymers and efficient micro-organisms (EM). Thus, improving its chemical, physical and biological soil properties and hence increasing its productivity. Furthermore, the soil is surrounded with plastic sheet to keep essential nutrients and water from leakage. After that, the BSVG are cultivated with 4 rotation cycle by different kinds of vegetables. A 40% higher yield output and a savings of 60% of irrigation water is achieved compared to traditional untreated soils.

Abstract: Biochar machine includes a sealed container for rice straw bales with two gates. The top gate is for rice straw feeding and the bottom gate for Biochar. The Biochar unit is equipped with a stirrer operated by an electric motor and a speed reduction unit. The Biochar unit is operated indirectly through a combustion chamber with a fuel burner to heat the sealed container from all sides indirectly. The gases produced as a result of heating the rice straw are collected and returned back to the combustion chamber through a blower.
