A final motivation for the use of symbolic methods is the fact that all discrete solutions can be obtained as functions of unknown parameters..In this paper, we focus on a special class of partial differential equations derived from geometric problems. A main challenge in this class is the

Improving nitrogen fertilization in mechanized rice culture,lfur-coated urea and nitrapyrin soil incorporated with urea reduce N loss in dry-seeded rice. Total N requirements of rice in the cultural systems is dependent on cultivar, soil N fertility and other factors. Plant analysis research establishes critical N concentrations in semidwarf and tall rice cu
