ABSTRACT (cont.): Results showed that the mixes, which produced higher plant dry weights, were mixes from the 0% compost to the 40% compost substitutions. The 60% compost mix produced the same plant dry weight as the mix used as a control (60% peat). There were no significant differences in the mixes for total porosity and air space. Bulk density increased with the amount of compost in the mix. Container capacity and moisture content decreased with increasing compost in the mix. Analysis of chemical properties showed that compost provided micronutrients in the sufficiency range. Diagnostic leaf tissue analysis did not revealed any deficiencies or toxicities to plants with the addition of compost. The third objective was to compare common nursery mixes that contained peat with mixes that had compost instead of peat. Physical properties tests revealed that all mixes were within the recommended range values, but compost provided more air space and bulk density but less container capacity and moisture content. Total porosity remained the same. Chemical properties tests showed that compost provided sufficient chemical elements compared with the peat mixes. The pH in peat-based mixes was too low for plant growth. Plant growth parameters showed dry weights were higher in compost mixes, and plant size was similar to those in peat mixes.

The dramatic worldwide increase in agricultural and industrial productivity has created severe environmental problems. Soil and groundwater reservoirs have been polluted with pesticides, xenobiotics and agro-chemicals. The global consensus to reduce inputs of chemical pesticides and agrochemical fertilizers, which are perceived at being hazardous by some consumers, has provided opportunities for the development of novel, benign sustainable crop management strategies. The future of agricultural depends upon our ability to enhance the productivity without damage to their long-term production potential. One of the strategies is the application of effective microbial products beneficial for both farmers and ecosystems. This kind of approach can ensure both ecological and economic sustainability. Soil microbial populations are immersed in framework of interactions, which are known to affect plant fitness and soil quality. For betterment of life of human being, improved quality and variety of products are formed due to versatile action of different group of microorganisms, Microbes are able to degrade solid waste material into compost which is a mixture of decayed organic matter, manure etc. Incomplete microbial degradation of organic waste where the microbial process varies aerobic to anaerobic form is stated as compost, if added to soil improves plant growth and development. The biological activities and microbial metabolism in the soil contribute to alter its mixture and fertility. Incorporation of organic remain in the form of compost is known to influence favourably the physio-chemical and biological properties of soil. The beneficial activities bestowed upon plants by compost utilization are multifaceted, hence most promising alternatives for achieving sustainable agricultural production. An increased awareness on compost has led to their use in agricultural concern. Contents in the present book will comprised various chapters on the role of beneficial bacteria in the composting process. The application is depicted to achieve the attainable productivity besides, in disease management and suppressiveness of organisms of phytopathogenic in nature. Significance of the compost elicits certain responses e.g. soil reclamation, soil fertility, soil health and disease management exhibit due to quality compost amendment in soil. It serves as low cost prospective option for sustainable crop production and protection.

Nutrients in animal wastes from dairy operations can leach into surface water, causing eutrophication. This research aims to determine if compost can replace peat moss in greenhouse substrates. Bedding plants were grown in five mixes. 1) 100% compost, 2) 50% compost, 3) 50% peat moss, 4) 25% compost; 25% peat moss and 5) 100% peat moss. The plants were grown to marketable size and rated for marketability. They were dried, weighed and analyzed for nitrogen and phosphorus. Plants grown in mixes including compost had weights, and nutrient levels that were equal to or higher than those grown in peat moss. Conclusion: compost is a suitable substitute for peat moss in greenhouse substrates.

The last two decades have seen rapid advances in the technology used to produce pot plants. Glasshouses designed and orientated to give maximum light transmission, fully automatic heating and ventilating systems, carbon dioxide enrichment of the atmosphere, controlled photoperiods using automatic blackouts and incandescent lamps which enable plants such as chrysanthemum to be flowered at any time of the year, mist propagation techniques, chemical growth regulators which control the height of plants, automatic watering and feeding systems, etc.: these are only some of the developments which have transformed pot plant culture. There have also been many changes in the composts and systems used to grow the plants. Mineral soils, which formed the basis of the John Innes Composts, are now either too expensive or too difficult to obtain in suitable quality and sufficient quantity. Consequently the grower has been forced to seek other materials such as peat, perlite, vermiculite, plastic foam, shredded bark, etc. New types of fertilisers, new methods of heat sterilisation and new chemical sterilising agents are also being used.
