LITERATURE REVIEW

Literature survey was conducted for the development of fertilizer tablet making machine, mainly in the area of fertilizers uses, fertilizers types ,fertilizers losses, crops type and fertilizer require for it, rolling compaction process and machine design. Dr. M. S. Lupin Mr. J. R. Lazo Mr. N. D. Le Mr. A. F. Little [2] In this paper alternative process of urea super granules is explained that is briquetting .The physical and chemical characteristics of urea make the material well suited for production of urea supergranules by briquetting. Briquetting of urea fertilizer up to 0.8 to 2.0 grams produced by International Fertilizer Development Center (IFDC).

Rajiv Shah [3] describes the deep placement of urea briquettes .This method is simple and effective. Instead of applying urea, a nitrogen fertilizer, to the soil, where as much as 70 percent is lost to runoff or the atmosphere .It is compacted in to briquettes and buried near plant roots, where it releases nitrogen slowly

Krushiswadini, 2012 [1] in this book different types crops, their fertilizer require quantity and there area is given for Vidarbha region. From data of fertilizer quantity, duration and number of crop in each hectare, calculate fertilizer require for single crop, as shown in following table. From this quantity fertilizer tablet size find

The elements present in soil are varying from farm to farm so due to this fertilizer providing according to elements present in the soil. The following table shows fertilizer providing quantity according to elements present in the soil.
