Fertilizer requirements and management issues for nonacid soils in nonirrigated areas.
1988
Garcia R. | Senigagliesi | McMahon M.A.
Fertilizer use on wheat has always been low in Argentina, due to a number of economic reasons. With the introduction of high yielding semi-dwarf varieties in the 1970s, fertilization has become much more feasible. This paper shows the response of wheat to N and P in the Pampa Humeda and analyzes the soil and climatic parameters that condition yield and response to fertilizer. Moisture availability affects both yield and response, as does length of fallow period and the previous crop. Soil analysis for nitrogen does not give a good correlation for nitrogen response, but soil analysis for P is highly correlated to P response.
