Описание: Presented in this well-illustrated book is an up-to-date account of the fundamental as well as applied aspects of research into biofertiliers which have large-scale application as supplements to chemical fertilizers in modern-day crop cultivation and forestry pratices. Biofertilizers can be more appropriately called 'microbial inoculants' and it is now accepted that microbial processes are not only quicker but also consume relatively less energy than microbial processes. These processes have the advantage of being diversified into small units to meet the demands of location-specific problems related to the agriculltural and silvicultural practices of nations which have not yet adopted agricultural mechanisation.

Описание: The presented book describes the results of the research of the project titled Phosphorus Renewable Raw Materials A Resource Base for the New Generation of Fertilizers attributed to the National Center for Research and Development of Poland. This book is divided into three chapters that are assigned to different stages of the project undertaken by different R&D institutions. The concept and possible options of valorization of waste biomass, such as bones, fish bones, and ashes originated from the incineration of sludge from a waste-water treatment plant from the tertiary stage of biological treatment as resources of phosphorus were described by the team from Wroclaw University of Science and Technology. As a method of by-products valorization, the solubilization process was proposed. Two strategies were proposed: Ex-situ and in-situ. The in-situ manner resulted with suspension fertilizer with a low concentration of P2O5 while ex-situ gave the possibility to obtain two solid formulations with the high content of P2O5. All of them could be used in agriculture and horticulture as granular fertilizers or as substrates. The different content of P2O5, as well as other nutrients in obtained formulations, were described as an effect of utilization of different raw materials as well as various additional substances such as binders necessary for the stability of final formulations. What is more, the efficiency of obtained formulations was strongly related to the kind of microorganism used as an activator of unavailable phosphorus, which was discussed in details. The technology of production for biofertilizers in pilot-scale was described by the Institute of New Chemical Synthesis in Pulawy with the following issues underlined: Design of installation to produce fertilizers based on renewable raw materials; plant construction and production of the product; and preliminary economic analysis. The University of Warmia and Mazury in Olsztyn described the utilitarian properties of new fertilizer formulations that were evaluated in field tests with special attention to granular and suspension biofertilizer. In that chapter, the major results of the agronomic evaluation of new suspension and granular phosphorus biofertilizers from secondary raw materials (sewage sludge ash, animal bones, and animal blood) were presented. Biofertilizers contained Bacillus megaterium or Acidithiobacillus ferrooxidans bacteria. New bioproducts were tested in field experiments in reference to traditional commercial phosphorus fertilizers (superphosphate, phosphorite, etc.). The research confirmed that phosphorus biofertilizers from renewable raw materials were similar to commercial fertilizers in terms of their crop-enhancing efficiency and did not reduce yield quality and quantity.

Описание: Organic fertilizers are an essential source for plant nutrients and a soil conditioner in agriculture. This book explains how to use such organic fertilizers as compost, green sand, mulch, bone meal, and green manure to keep soil healthy with some real examples extending the concepts in organic fertilizers that may stimulate new research ideas and trends in the relevant fields.
