1. How to Grow Soybeans

1. Careful land preparation

Deep plowing should be carried out according to the previous crop, with a depth of 22-25 cm. During operation, no large clods of soil should be produced, and no clear strips or clods should appear. The soil must be tightly closed, with no overlap or gaps.

2. Sowing at the right time

For summer-sown soybeans, after the wheat harvest, as long as the soil moisture is suitable, they can be sown. The best sowing period is from June 10 to 25, and at the latest no later than early July.

3. Fertilization method

Under normal circumstances, fertilizer and seed should be kept separate, applied 4-5 cm below and to the side of the seed, and the amount of chemical fertilizer can be adjusted. When applying more than 20 kg of diammonium phosphate per 667 sq m, it can be applied in layers: the upper seed fertilizer layer at a depth of 5-7 cm, accounting for 1/3 of the fertilizer amount; the base fertilizer layer at a depth of 10-16 cm, accounting for 2/3 of the fertilizer amount.
