Average soybean yield is low compared with the potential yield. N is derived from three sources; N_2 fixation, soil N, and fertilizer N. A heavy supply of N fertilizer often depresses nodule development and N_2 fixation activity, which sometimes resu

We have shown in previous reports that a new fertilization method with deep placement of slow-release N fertilizers, such as coated urea and lime nitrogen (calcium cyanamide), at a depth of 20 cm promoted soybean growth and seed yield. In the present

Nitrogen, phosphorus and potassium are three major nutrients, whose availability often become limiting factor to plant growth and crop yield. We have published in our previous reports that a new fertilization method with deep placement of slow releas

Average soybean seed yield in Japan is less than 2t ha-1, although the seed yield is sometimes much higher up to 6t ha-1 in a well managed field under good climatic conditions. Therefore, the present study was carried out in view to obtain better see

Soybean (Glycine max [L] Merr.) plants can utilize N2 fixed in the root nodules. Also, they can use the N absorbed from roots, from soil mineralized N or from fertilizer N when applied either in the form of nitrate or ammonium (Ohyama et al. 1989). H
