Plant biostimulants: what they are, how to apply them and their importance

Biostimulants have changed agriculture for the better, as they improve the plant health and productivity, which is very important in soybean production, for example.

Using this product and inoculants reduces the need for chemical fertilizers. They also make plants more resistant to stresses. This includes bad weather conditions, diseases and pests.

Products such as DualForce and Rizotec are examples of advances. DualForce increases soybean productivity. Rizotec protects against diseases without chemicals.

Using biostimulants brings many benefits. They improve agriculture and make it more sustainable.

However, it is important to know how to use them correctly, as this helps plants absorb these products better. This means the soil becomes healthier and richer in nutrients.

It is crucial to expand knowledge about biostimulants. This benefits farmers, researchers and everyone seeking a sustainable future in agriculture.

Definition and sustainable approach to plant biostimulants

THE definition of biostimulants encompasses several compounds used in agriculture to improve plant health and growth.

They include beneficial microorganisms, algae extracts, amino acids, and plant hormones. These products help keep the soil healthy and help plants adapt better to difficult conditions.

Using this product reduces the need for chemical fertilizers and pesticides. This helps promote a sustainable agriculture. This approach is good for the environment and for farmers.

Integrating them into cultivation practices strengthens plants and improves nutrient absorption. This leads to higher productivity.

For example, using Stoller’s DualForce has significantly increased soybean yields. This shows the value and economic viability of these biological solutions.

Agriculture faces challenges such as climate change and pests, requiring innovative solutions. Biostimulants are a good alternative. They improve plants without harming the environment.

Products such as seed treatment with phenylalanine improve soybean productivity. This shows the effectiveness of biostimulants in more productive and resistant crops.

The role of biostimulants in optimizing soybean productivity

The introduction of biostimulants in soybean cultivation brings about major changes. They greatly improve productivity and help to make the crop more sustainable.

Products such as DualForce inoculant and BlueN solution are good examples. They use biological agents to increase efficiency and reduce environmental damage.

DualForce helps plants grow healthier and fix more nitrogen. This results in plants having strong roots and growing better.

BlueN helps to capture nitrogen from the air, which is good in soils with little microbial life. This reduces the use of chemical fertilizers and improves sustainability.

Studies show that biostimulants are very important in agriculture. They can reduce the use of chemicals, cut costs and protect the environment.

DualForce, for example, can greatly increase soybean production, bringing more profit to producers. Other products, such as Rizotec, also improve... plant health, making them more productive.

By 2030, the bioinputs market in Brazil could grow 200%. This shows that more producers are using these technologies.

They seek not only to produce more, but also to be more sustainable. The benefits of bioinputs, such as improving soil health and nutrient absorption efficiency, are great.

Furthermore, they also promote a green and productive future for agriculture in Brazil.

Benefits and mechanisms of action of plant biostimulants

Plant biostimulants bring many benefits. They improve the stress resistance and create an ideal environment for plants to grow healthily.

These substances, organic or synthetic, improve nutrient absorption and regulate important processes in plants.

Biostimulants act at the cellular level. They help plants absorb nitrogen and other essential nutrients. This is crucial for protein production and plant growth.

For example, amino acids such as glutamic acid and glycine stimulate nitrogen metabolism, which is vital for photosynthesis and root growth.

Additionally, they increase the activity of antioxidant enzymes such as superoxide dismutase and catalase. These enzymes combat oxidative stress caused by adverse conditions such as heat and lack of water.

Biostimulants not only help plants cope with stresses now, but also prepare them for future challenges.

This is very useful for crops that face unpredictable or suboptimal weather conditions. This 'priming' or preconditioning process makes plants more resilient to future disturbances.

Understanding these mechanisms gives farmers and scientists a powerful tool.

They can improve crop health and yields without using a lot of chemical fertilizers.

Thus, they contribute to a greener and more sustainable agriculture.

Procedures for the effective application of biostimulants in crops

The bio-inputs market reached US$10 billion in 2021 and is expected to grow further. It is crucial to discuss agricultural management and strategies for using biostimulants.

These products are essential for increasing productivity and caring for the soil.

With large companies like Bayer and Corteva, the bio-inputs market is booming.

By using biostimulants, we are investing in modern and sustainable agriculture. This follows the trend towards more environmentally friendly practices.

To get the most out of this product, it is important to apply it at the right times. This includes everything from seed treatment to foliar application.

A good one agricultural management considers the needs of each culture and the environment.

Combining different types, such as humic substances and amino acids, improves soil nutrition.

This also helps to have more beneficial microorganisms. In Brazil, the adoption of biofertilizers has grown by almost 40 million hectares.

Add biostimulants to agricultural management is crucial to have strong plants and sustainable crops. This meets the demands of the market and society.

FAQ about Plant Biostimulants

What are plant biostimulants?

Biostimulants are substances or microorganisms that, when applied to plants, stimulate natural processes such as germination, root growth, flowering and fruiting.

They are not fertilizers, as they do not provide essential nutrients, but they act as catalysts, enhancing the efficiency of other agricultural inputs.

What are the benefits of using biostimulants?

• Increased productivity: Biostimulants can increase the quantity and quality of agricultural production.
• Improved fruit quality: Fruits tend to be larger, have better flavor and a longer shelf life.
• Greater resistance to stress: Plants treated with biostimulants show greater tolerance to adverse conditions such as drought, salinity and extreme temperatures.
• Reduction in the use of agrochemicals: Biostimulants can reduce the need for pesticides, contributing to more sustainable agriculture.
• Improved soil health: Some biostimulants promote the development of beneficial microorganisms in the soil, improving its structure and fertility.

What are the types of biostimulants?

There are several types of biostimulants, with different compositions and modes of action. Some of the most common are:

• Seaweed extracts: Rich in plant hormones, vitamins and minerals.
• Amino acids: Essential for the synthesis of proteins and enzymes.
• Humic and fulvic acids: They improve soil structure and nutrient availability.
• Beneficial microorganisms: Bacteria and fungi that promote plant growth and protection against pathogens.

How do they act on plants?

Biostimulants act in different ways, such as:

• Hormonal regulation: They stimulate the production of plant hormones, such as auxins, gibberellins and cytokinins.
• Improved nutrient absorption: They increase the roots' ability to absorb water and nutrients from the soil.
• Stress protection: They activate plant defense mechanisms against adverse conditions.
• Root growth promotion: They stimulate the development of a more vigorous root system.

What is the best way to apply biostimulants?

The application method of biostimulants varies according to the product and crop. They can be applied via foliar application, fertigation or directly to the soil.
