Consequences of Compost Press Mud as Fertilizers

Organic fertilizers derived from Sugar Press Mud (SPM) yields better production of crops. Sugar press mud or the sugarcane filter-cake is the residue of sugarcane industry which results from the processing of sugarcane where sugar mud is separated from the crush. The total supply of sugar press mud varies from (1-7) kg from the processing of 100 kg of sugarcane. Sugar filter cake is used as a suitable fertilising agent since it is rich in micro and macro nutrients along with organic carbon. It is eco-friendly and protects the plants from various soil borne diseases. Press mud compost does not include any substances which are unfavourable for microbial action. In certain cases, press mud is mixed with other organic fertilizers to yield enriched compost. Whatever the case, the resultant press mud should not be added to the soil directly as it affects the welfare of human health due to the fast growth rate of pathogenic fungi. These are the disease causing microbes whose growth rate must be inhibited. The review deals with the physical, chemical and microbial functions on the press mud resulting in excellent bio-fertilizers. Enriched press mud is mixed with gibberellic acid to inhibit the growth of toxic chromium which affects the metabolism of plants. The fields which are ineffective by the over use of chemical pesticides can be brought into control by constant use of bio-fertilizers such as press mud. Usage of chemical pesticides may destroy the insects causing damage to the fields, but its impact over the health of living beings is tremendous. Press mud, on the other hand, is safe and very effective in producing income and killing certain insects affecting the crops as well.
