The key to applying nitrogen fertilizer to soybeans is "smart"
In the middle and lower fertility fields, timely and appropriate application of nitrogen fertilizer has a better yield-increasing effect; the yield increase effect of the higher fertility field is not obvious, and excessive application is not only wasteful, but also causes a reduction in production. Generally, 5 kg of urea or 15 kg of ammonium bicarbonate can be used as the base fertilizer per acre; low-fertilizer or no-fertilizer can be applied in high-fertilizer fields, and a small amount of nitrogen fertilizer can be used as a seed fertilizer for better effect, which is beneficial to soybean seedlings and flower bud differentiation. However, the amount of seed fertilizer should be less, so that the fertilizer should be isolated to avoid burning. Generally, the bulk plant fertilizer is applied with 3 to 5 kg of urea per mu, and 10 to 15 kg of superphosphate is suitable, or 2 to 3 kg of urea per acre plus 3 kg of diammonium phosphate. The yield increase effect will be more obvious.
Soybean is applied with nitrogen fertilizer before or during flowering. It also has a good yield-increasing effect. It can be applied with 3 to 5 kg of urea per acre. It can be applied before cultivating, and then immediately cultivated.
