As a result, total nitrogen （N）, phosphorus （P）, magnesium （Mg） and potassium （K） contents were influenced by the treatments to a different extent, while calcium （Ca） contents were less influenced. Evaluating the seasonal mean, P and K contents rose significantly from autumn 1 to autumn 2 season, but the increase in total N, Ca and Mg contents were found to be statistically insignificant. Consequently, 10.0 ton ha-1 FM ＋ 1.2 ton hal CM and 1.7 ton ha-1 CM ＋ 7.5 ton ha^-1 FM treatments gave the better results than the others. FM and CM treatments gave the better results than the BM treatment and we concluded that the BM should be used in small quantities in mixtures.展开更多

This paper deals with using soil analysis as a base for fertilizer use in maize. A field experiment was carried out in two summer seasons of 2013 and 2014 with maize (triple hybrid) in Oraby Village, Mariut sector, Alexandria, Egypt. Soil testing shows that soil was clay loam, with high Na and CaCO<sub>3</sub> contents with high pH, low organic matter, medium P and K and low micronutrient contents (Fe, Zn, Mn and Cu), seven treatments were designed. The most promising treatment was when P and K were increased and micronutrients were added based on soil testing. This treatment resulted in the highest yield with better grain contents of protein and nutrients which indicated that soil-test based on fertilizer use was superior. Soil analysis at the end of the experiment showed higher P and K contents. This approach could be adopted for regions with similar soil conditions in other parts of the world.展开更多
