Currently, it is impossible to talk about soybean cultivation without addressing alternatives that add value to this important crop. Today, we have a lot of information available at any time, which can help increase soybean productivity.
When we get into this topic, we must start with the main thing: what should we put in the seed to help in the development of the culture? Inoculation is nothing more than an agricultural practice that establishes contact between bacteria and seeds, which can be done manually or mechanized. The two most common methods are seed treatment and application in the planting furrow. In both cases, the objective is to ensure that the bacteria have contact with the seeds and can develop, helping the growth and productivity of the plants.
The gains in productivity of soybeans inoculated with bacteria from the Bradyrhizobium spp. they can reach an 8% increase when compared to non-inoculated plants. When we perform coinoculation, which is the use of bacteria from the genera Bradyrhizobium spp. and Azospirillum spp., we can achieve even greater productivity results, reaching up to a 16% increase.
Interesting microorganisms Nitrogen (N) is the macronutrient most required by soybean crops, which requires, on average, 80 kg of N per ton of grain produced. The plant is able to meet a large part of its needs through the process of biological nitrogen fixation (BNF). Fortunately, there is a tool that has been used and is here to stay: inoculation. Inoculation is an essential process and an ally in plant development, as it provides nitrogen via bacteria of the genus Bradyrhizobium. These bacteria are responsible for FBN, a process in which bacteria symbiotically associate with plant roots, producing nodules that help transform N² in the air into N, which is in the form available to plants. In the figures below we can observe the presence of nodules on the roots of the soybean crop, and how these nodules carry out their process.
