Late‐season foliar fertilization with macronutrients – is there a theoretical basis for increased seed yields?

摘要: Abstract The hypothesis that leaves of soybean plants need to senesce in order provide nitrogen for seed development has been used explain the mechanism by which late‐season foliar applications N P K and S solutions sometimes increase yields. A review results recent field laboratory trials suggests fertilization does not inhibit leaf senescence such is any case a primary factor limiting
