0000006539 00000 n This can happen if the pile has received too little oxygen or too little or too much moisture. The process involves decomposition of organic material into a humus-like material, known as compost, which is a good fertilizer for plants. 0000005322 00000 n 0000054939 00000 n There are slightly different assumptions used to calculate the space requirements in each stage and efficiencies to be gained by calculating them separately. curing stage begins. 0000009990 00000 n (����i����"�SS�3R�q���?b-��F��0��+�e!�!��F^�|Hʼn����|�-��C��5��UA6����yYaE�APT�+`�� The Phases of Composting. endstream endobj 177 0 obj << /Length 240 /Filter /FlateDecode >> stream In the primary stage, a high rate of biological activity results in rapid composting and high temperatures in the pile. The four phases include: 1) the mesophilic phase; 2) the thermophilic phase; 3) the cooling phase; and 4) the curing phase. We all know that Red Wiggler worms (Eisenia foetida) are amongst the most popular worm specie in worm composting and organic gardening.Let's get to know these amazing little nature's wonders a little bit more as we explore the interesting life cycle of Red Wiggler worms or Eisenia foetida.. We will discuss the whole life cycle of these worms from its cocoon stage up to its egg laying stage. Composting is an aerobic process, during which organic waste is biologically degraded by micro-organisms to humus-like material. As microbial activity increases, the massive release of metabolic energy raises temperatures above the mesophilic and into the thermophilic range, … In a compost pile destined to go out in a blaze of glory, the demise of the mesophiles eventually sets the stage for thermophilic composting. 0000001250 00000 n Although the same phases occur during continuous composting, they are not as apparent as they are in a batch, and in fact they may be occurring concurrently rather than sequentially. In the active composting stage, microorganisms consume oxygen (O 2) while feeding on organic matter in manure and produce heat, carbon dioxide (CO 2) and water vapour. ��yaJ��y�J�i�����T�5O��(W�,Ǘ��rc�ؠ���ɩ3��b�Jm�3�o@�專�d/��(Jڟ���a�1qB���#XR� Kj��g�� 8 Phytopathogenic Aspects of Composting 76 8.1 Inactivation of Plant Pathogens during Composting 77 8.2 Adverse Effects of Fresh, Immature Compost on Plant Growth 77 8.3 Control of Soilborne Plant Pathogens by Compost 77 8.4 Control of Foliar Diseases by Compost Water Extracts 78 9 Balancing the Composting Process 78 9.1 Mass Balance 79 Composting is the decomposition of organic materials by microorganisms under controlled, aerobic conditions to a relatively stable humus-like product suitable for growing plants, which poses no hazard to human health or the environment1.
