Soy cultivation

SOY CULTIVATION

The cultivation of soy is not intensive and processing is now possible to grow soybeans also in Northern Europe.

 

In order to grow soybeans there are however a few things that you should consider in order to achieve a good result.

 

  • Ground
  • Temperature
  • Appropriate breeds
  • Sow
  • Inoculate
  • Fertilizing
  • Crop protection
  • Harvest
  • Warehousing

Easy soy seed ordering at DutchSoy.

Ground

Soy can be cutivated in both clay and sandy soils. It is important that the soil has good moisture balance. Soya grows best in a soil with a pH value of 6-7. Do you have a soil pH value of <3.9 or> 9.6 is not recommended to cultivate the soy.

 

Temperature

Soy is a subtropical plant from origin, so it needs temprature to grow. The soybean plant can therefore not stand frost. 1 to 2 degrees frost often means survival but it still depends on the stage of the plant and the period of frost.

Crop protection

 

Because soy cultivation in Europe is growing considerably, the number of authorized plant protection products also increased in the Netherlands. The authorized crop protection in the soybean crop for 2017 in the Netherlands:

 

Pre emerge herbicide: Centium and Sencor liquid

Herbicide: Basagran

Fungicide: Prosaro and switch  

 

DutchSoy do not allows the use of glyphosate as pre harvest treatment. Due to residues and therefore limited market. After sowing pre-emergence glyphosate may be used.

SUITABLE BREEDS

 

In the Netherlands only the early varieties are suitable for cultivation because of the late late ripening. Later varieties can give more revenue potential, but mature later then the 000 varieties. The ripening of 000 varieties in the Netherlands is in late September early October and that is already late.

 

Fortunately, the breeding for sybean is getting bigger and bigger and, more and more varieties in the 000 group become available. Before you make a choice for the varietie, it is wise to reflect what will be your market. There are several varieties, each features within it that may be of interest to different markets. There for the harvesting of dry soybeans often needs high protein. For tofu production yhey need a white hilum and for the fresh soybeans the taste is importent.

So before you make a decision for your varietie please concider your market. Dutchsoy you can advise what is the best choice in your situation.

Sowing soybeans

Soybean is sown in late April early May when the soil temperature is at least 10 degrees. This is due to the coting rhizobia on the seed, but more about that in inoculeren.The preparation of the soil for sowing works best with a harrow (roterkopeg). A loose topsoil and 5 cm moist soil. Soy is in fact deeply seeded at 4 to 5 cm. Sow about 600,000 seeds per hectare which usually amounts to 100 kg. After investigation it has been found that the ideal driving distance is 25 cm. Further, from each other, provide more firmly resistence to alloy and it gives a stronger plant. Closer results in earlier ripening and earlier crop cover on the field. Sowing can be done with a precision drill but in practice a drill pipe works just fine. For soybean there is no separate mechanization required in order to be able to sow the soy.

 

Inoculate

Soy is a leguminous plant which means that, by working together with a bacterium it is capable of binding the nitrogen from the air. The specific bacteria to the soybean plant is Rhizobium japonicum who are notcommen in the ground of Europe and there fore should be included. This happens often with a coating on the seed we call inoculated seed. With good cooperation between the bacteria and the soybeanplant it can bring up to 70% of its nitrogen demand from the air. If de sympyoses works you find knobs on the roots.You can see if the rhizobia is active by halving a knob and see if he is red inside. The Rhizobium is also allowed in organic farming. Remember when seeding that these bacteria can not stand UV light. Avoid direct contact with the sun if you are seeding it may completely kill the bacteria.

 

Harvest

Under Dutch conditions, the soybean is harvested in late september early oktober depending on the variety and growing season.The adjustments for the combine are in the instruction booklet of every combine.

Try to keep the header as low as possible to be able to take the low-hanging pods if not it could result in a loss of up to 10 %.

The soybean ripens by first becoming brown and lose its leaves. The stems remain with the pods and are then harvested. A soybean is not like a pea and does not open and loose the beans to the ground under dutch conditions.

 

Warehousing

If you wants to store the soybeans the best preserved soya humidity is at 13 to 15% moist. In the Netherlands, the values ​​are often higher and it is wise to bring it directly to a place where itcan be dried. Above 20% moisture fungi occur guikly so that the soy may be rejected by the market.

If you want to dry the soybean itself, for example in crates. Remember that the drying temperature does not exceed 60 degrees and to long because the beans will split.
