Soybeans are one of the most widely cultivated legumes globally, with the United States, Brazil, and Argentina being among the top producers. While mechanical harvesting is the most common method used in large-scale soybean farming, manual harvesting is still a viable option for small-scale farmers, gardeners, and those in areas where mechanized equipment is not readily available. In this article, we will delve into the process of manually harvesting soybeans, highlighting the benefits, challenges, and best practices to ensure a successful and bountiful harvest.
Pre-Harvest Preparation
Before embarking on the manual harvesting process, it is essential to prepare your soybean crop for the best possible outcome. Here are some key steps to take:
Checking for Maturity
Soybeans are typically ready for harvest when the plants turn yellow and the leaves drop off. The beans should be dry and rattle inside the pods. To check for maturity, gently pull a pod from the plant and inspect the beans. If they are dry and easily removable from the pod, they are ready for harvest.
Removing Weeds and Debris
Clear the area around the soybean plants of any weeds, debris, or obstacles that may hinder the harvesting process. This will make it easier to move through the field and reduce the risk of contamination.
Gathering Equipment
You will need the following equipment for manual harvesting:
- A sharp knife or pruning shears for cutting the soybean plants
- A basket or container for collecting the harvested soybeans
- A pair of gloves to protect your hands from thorns and other sharp objects
- A first-aid kit (just in case)
The Harvesting Process
Now that you have prepared your soybean crop for harvest, it’s time to start manually harvesting. Here’s a step-by-step guide:
Cutting the Soybean Plants
Using your sharp knife or pruning shears, cut the soybean plants near the base of the stem, leaving a small portion of the stem intact. This will make it easier to handle the plants during the harvesting process.
Removing the Pods
Hold the cut soybean plant over your basket or container and gently pull the pods from the stem. You can also use your knife or pruning shears to cut the pods from the stem if they are particularly stubborn.
Removing the Soybeans from the Pods
Once you have collected the pods, you will need to remove the soybeans from the pods. You can do this by hand or using a simple tool like a small hammer or a rock. Gently tap the pod to release the soybeans, and then collect them in your basket or container.
Drying the Soybeans
If the soybeans are not completely dry, you will need to dry them further to prevent mold and spoilage. You can do this by spreading them out in a single layer on a clean surface, such as a concrete floor or a wooden table. Allow them to air dry for several days, stirring them occasionally to ensure even drying.
Post-Harvest Handling
After harvesting and drying your soybeans, it’s essential to handle them properly to maintain their quality and prevent contamination. Here are some tips:
Storage
Store your harvested soybeans in a cool, dry place, such as a barn or a storage shed. Keep them away from direct sunlight, moisture, and pests.

What are the benefits of manually harvesting soybeans?
Manually harvesting soybeans can be a cost-effective and efficient method for small-scale farmers or those with limited access to machinery. This approach allows for more control over the harvesting process, enabling farmers to carefully select and handle the soybeans to minimize damage and maximize yield. Additionally, manual harvesting can be a more environmentally friendly option, as it eliminates the need for fuel-powered machinery and reduces the risk of soil compaction.
Manual harvesting also provides an opportunity for farmers to inspect their crop more closely, allowing them to identify any issues or defects that may have arisen during the growing season. This can help farmers to refine their cultivation techniques and make improvements for future crops. Furthermore, manual harvesting can be a more labor-intensive process, which can create jobs and stimulate local economies.
What equipment is needed for manual soybean harvesting?
The equipment needed for manual soybean harvesting is relatively simple and inexpensive. The most essential tool is a sharp knife or sickle, which is used to cut the soybean plants near the base of the stem. A pair of gloves can also be useful to protect the hands from thorns and other sharp objects. Additionally, a basket or container is needed to collect the harvested soybeans. For larger-scale manual harvesting operations, a small cart or wagon may be useful for transporting the harvested soybeans to a central location.
Other equipment that may be useful for manual soybean harvesting includes a measuring tape or string to mark out the harvesting area, and a small rake or broom to gather any scattered soybeans. Depending on the size of the crop, a small team of workers may also be necessary to assist with the harvesting process. It’s also important to have a clean and dry area for drying and storing the harvested soybeans to maintain their quality.
How do I prepare my soybean crop for manual harvesting?
Before manual harvesting, it’s essential to prepare the soybean crop to ensure a smooth and efficient process. This involves inspecting the crop for any signs of disease or pests, and removing any weeds or debris that may interfere with the harvesting process. The soybean plants should also be dry and mature, with the leaves having turned yellow and fallen off. If the plants are still green, it may be necessary to wait a few more days before harvesting.
It’s also important to check the weather forecast before harvesting, as manual harvesting is typically more efficient in dry and sunny conditions. If the weather is wet or windy, it may be necessary to postpone the harvest until conditions improve. Additionally, farmers should ensure that they have a clear and safe path through the crop to avoid any accidents or injuries during the harvesting process.
What is the best time of day to manually harvest soybeans?
The best time of day to manually harvest soybeans is typically early in the morning, when the dew is still present on the plants. This helps to reduce the risk of soybean shattering, which can occur when the plants are dry and brittle. Harvesting in the morning also tends to be cooler and more comfortable for the workers, which can help to improve their productivity and efficiency.
It’s generally recommended to avoid harvesting soybeans during the hottest part of the day, as this can cause the workers to become fatigued and increase the risk of accidents. If possible, it’s also best to avoid harvesting during windy or wet conditions, as this can make the process more difficult and reduce the quality of the harvested soybeans.
How do I dry and store manually harvested soybeans?
After manual harvesting, it’s essential to dry and store the soybeans properly to maintain their quality and prevent spoilage. The first step is to dry the soybeans to a moisture level of around 12%, either by spreading them out in the sun or using a mechanical dryer. This helps to prevent mold and bacterial growth, which can damage the soybeans and reduce their value.
Once the soybeans are dry, they should be stored in a clean and dry container, such as a bin or bag. The container should be sealed to prevent moisture and pests from entering, and the soybeans should be kept in a cool and well-ventilated area. It’s also important to monitor the stored soybeans regularly for any signs of spoilage or infestation, and to take action promptly if any issues arise.
Can I manually harvest soybeans with a large crop?
While manual harvesting can be a viable option for small-scale soybean crops, it may not be practical for larger crops. Manual harvesting can be a time-consuming and labor-intensive process, which can be challenging to scale up for larger crops. However, there are some strategies that can be used to make manual harvesting more efficient for larger crops, such as using a team of workers or implementing a more organized harvesting system.
One approach is to divide the crop into smaller sections and assign a team of workers to each section. This can help to speed up the harvesting process and make it more manageable. Additionally, using simple tools such as a small cart or wagon can help to reduce the physical demands of manual harvesting and improve efficiency. However, for very large crops, mechanical harvesting may be a more practical and efficient option.
