Última Best fit model selection for spatial differences (regression) in the profitability analysis of precision phosphate (P) application to winter cereals in Precision Agriculture (PA) AgEcon Hough, Ella Christina; Nell, Wilhelm T.; Maine, Ntsikane; Groenewald, Jan A.; van der Rijst, M.. Phosphates (P) are an important nutrient required by every living plant and animal cell, and deficiencies in soils could cause limited crop production, thereby reducing profitability. Phosphates are also a primary nutrient essential for root development and crop production, and are needed in the tissues of a plant where cells rapidly divide and enlarge. Precision agriculture (PA) could assist the farmer in applying the correct amount of P to the part of the field where it is required most. Variable rate technology (VRT) is a potential tool that can help with the development of strategies for phosphate fertilizer management. On-field trials were conducted on a commercial farm in the Western Cape Province; As many as five soil types occur on each field...
