growth stages and how to use plant nutrition and biostimulants to maximize
the genetic potential of your crop.
What are the nutritional requirements of a soybean crop?
Watch the video to learn about what nutrients are required by a soybean crop and the best times to apply them.
Essential nutrition for soybean crops
Essential nutrition for soybeans can be divided into five key stages. Preventing a nutrient deficiency at each of these stages is crucial for preserving the genetic potential of the crop to maximize yield potential. Use the tabs below to learn about the key nutrients required for each stage:
(Fungicide Timing)
Seeds are naturally nutritionally imbalanced – adding a seed nutrient dressing with the following nutrients can help the seedling get off to a strong start.
- Add an Inoculant to the seed to drive Nitrogen fixation.
- Soybean seeds are naturally nutritionally imbalanced – adding a seed nutrient dressing can help the seedling get off to a strong start. However, caution must be taken to ensure nutrient like Zinc are not added as it can harm the seed applied inoculant.
- Nutrients such as molybdenum formulated with biostimulants (Transit S and Cellburst) can help drive rooting and enhance early seedling vigour, without having negative effects on the inoculant.
- The other key goal with adding biostimulants to the seed is to address and help overcome early season stresses, such as cold soils.
To address the needs of the seedlings (and limitations within the seed) it is vital to ensure the soil has the key nutrients properly placed (either seed placed or banded close to the seed) to drive rooting, photosynthesis and early season vigor
- Zinc – auxin production to drive rooting
- Manganese – photosynthesis (responsible for splitting the H2O molecule)
- Boron – cell membrane integrity for strong, healthy roots
- Biostimulants (Synergro M2) – drive rooting and improved nutrient use efficiency
- Phosphorus* – energy production and photosynthesis
- Seed placed Phosphorus can injure a soybean crop and should NOT be applied in the seed row. If you are applying phosphorus, apply as a side or deep band.
During the vegetative growth stage, the crop is ramping up nutrient demand and energy production while still having a limited root system to acquire nutrients from the soil. The 3-6 leaf stage (V3-V6) is the ideal timing to combine these critical nutrients with a herbicide application to meet the increased nutritional demand of the crop and optimizing each pass across the field:
- Phosphorus – energy production and photosynthesis
- Potassium & Magnesium – critical for carbohydrate movement
- Zinc – root and shoot differentiation and moisture acquisition
- Manganese – optimize enzyme production and carbohydrate metabolism
- Boron – membrane integrity for strong, healthy roots
- Molybdenum – essential for optimizing nitrogen fixation by rhizobium
- Biostimulants (Transit-S and Cellburst) – abiotic stress management, root growth, & improving nutrient uptake and efficiency
(Fungicide Timing)
As the crop moves to the reproductive stage, there are key nutrients essential for pollination and fertilization. Ensuring these nutrients are present in adequate amounts prior to pollination is key:
- Zinc – auxin production for pollen tube elongation
- Boron – pollen tube growth and pollination
- Calcium – cell wall strength in the stigma
- Potassium – critical for carbohydrate movement
- Molybdenum – critical to convert nitrate-N into amino acids and proteins
- Biostimulant (Cellburst) – pollen tube growth and elongation
During later season ripening, this is the stage where nutrition can impact the quality of the cereal crop. Applying these nutrients later in the season can have a positive impact on ensuring yield and seed quality:
- Nitrogen – required when yield potential is greater than what rhizobium alone can supply to the plant.
