Soybean farming requires careful planning, from seed selection to harvest. In this comprehensive guide, you’ll learn how to prepare the soil, determine the optimal planting time, manage the crop, and calculate costs and revenues. You’ll also learn about the soybean growing season, regional specificities, and the factors that influence yield and profit per hectare.
Throughout this content, we will discuss the main characteristics of soybean cultivation in Brazil, including the conditions for soybean cultivation in the Northeast, considerations when selecting a soybean cultivation system, and aspects related to the cultivation of genetically modified soybeans.
How does soybean farming work?
Cultivation begins with soil analysis and crop planning. These steps help determine the appropriate acidity correction, fertilization, cultivar, spacing, and seed rate.
During the planning phase, the grower can treat the seeds on-farm or purchase seeds that have already been treated industrially (TSI). To reduce failures and promote plant establishment, it is important to protect the seeds against fungi, pests, and adverse conditions.
Plant emergence should be uniform. Therefore, factors such as seed quality and seeding conditions—including seeding depth, seeder speed, and seed distribution—must be monitored. Proper planting prevents gaps and plants that are too close together.
During the growing season, monitoring for pests, diseases, and weeds is conducted, in addition to nutritional management.
According to Embrapa, the planting season influences the crop’s exposure to weather conditions and can affect its yield.
When should I plant soybeans?
The best time to plant depends on the state, the climate, the cultivar, and the plant health calendar. In most growing regions, planting takes place when the rains begin and become regular.
Before planting, growers should consult their state’s official calendar. The Ministry of Agriculture establishes planting periods and fallow periods to reduce the incidence of Asian rust.
It is not enough to simply look at a date on the calendar. The soil must have sufficient moisture to allow for rapid germination and uniform establishment, without excess water or a high risk of drought immediately after sowing.
What is the growing season for soybeans?
The growing season for soybeans typically ranges from 90 to 150 days, depending on the cultivar, region, planting season, and weather conditions.
Early-maturing cultivars complete their life cycle more quickly, while late-maturing varieties remain in the field longer.
The cycle includes germination, vegetative growth, flowering, pod formation, seed filling, and maturation. Harvesting should begin at the right time to minimize losses and damage.
Embrapa reports that harvesting grain with a moisture content between 13% and 15% helps reduce mechanical damage and operational losses.
How to Choose a Soybean Farming System?
The soybean cultivation system should take into account the area's history, soil type, climate, available machinery, and the crops used in rotation.
In no-till farming, seeds are sown directly into the straw from the previous crop. This mulch protects the soil, reduces erosion, and helps conserve moisture.
It is also possible to practice crop rotation with corn, brachiaria grass, and other species. Crop rotation helps diversify the production system and can contribute to the control of weeds, pests, and diseases.
Choosing asoybean seedvariety suited to the region is essential. Growers should evaluate the seed’s origin, physiological quality, growth cycle, disease resistance, and maturity group.
What is soybean farming like in Brazil and in the Northeast?
Soybean cultivation in Brazil takes place in very different environments. For this reason, a cultivar that performs well in the South may not perform as well in the Cerrado or in regions with different temperatures and rainfall patterns.
Soybean cultivation in the Northeast is concentrated mainly in the Cerrado regions of Bahia, Maranhão, Piauí, and Tocantins.
In these regions, planning must take into account rainfall patterns, high temperatures, and the soil’s water-holding capacity.
Each property requires a region-specific plan.The technical recommendation should combine soil analysis, agricultural zoning, a plant health calendar, and cultivar characteristics.
What is the profit from 1 hectare of soybeans?
There is no fixed amount. Profit is equal to the revenue from the sale of the crop minus all costs, such as seeds, fertilizers, pesticides, machinery, fuel, labor, rent, and financing.
CONAB maintainscost surveysthat can facilitate comparisons, but producers should use the actual figures from their own farms.
How much is a 60-kg bag of soybeans worth?
The price fluctuates daily depending on the region, grain quality, exchange rates, supply, demand, freight costs, export premiums, and trading on international exchanges.
For business decisions, consult theCepea/Esalq Soybean Index, cooperatives, and local buyers.The reference price is not a guarantee of the final price.
FAQ – Frequently Asked Questions About Soybean Farming
What is genetically modified soy?
The cultivation of genetically modified soybeans involves cultivars that have been engineered through biotechnology to possess specific traits. Some of these cultivars are tolerant to certain herbicides or resistant to insects. Their use does not eliminate the need for monitoring, integrated pest management, and compliance with technical recommendations.
How many bags of soybeans are produced per hectare?
Yield varies depending on climate, soil, cultivar, management practices, and region. To estimate it, divide the total harvested weight by 60 and then by the planted area. The result should be compared to the cost per hectare, since high yield does not necessarily mean higher profit.
Do soybeans need a lot of water?
The crop needs water throughout its life cycle, especially during flowering and grain filling. Both a lack of water and an excess of it can hinder development. The distribution of rainfall is often just as important as the total amount received.
Can soybeans be grown in any type of soil?
Soybeans can be grown in different types of soil, provided that proper soil amendment and management are in place. Compacted, waterlogged, highly acidic, or low-fertility soils require special attention. Laboratory analysis should guide liming, fertilization, and other interventions.
What is the first step in planting soybeans?
The first step is to assess the area and conduct a soil analysis. Next, the farmer should select the crop variety, check the planting schedule, calculate costs, and prepare the machinery.The assistance of an agronomist helps reduce planning errors.
