The new technology of soybean ensures 25 sc/ha more; video

The company also says that it will invest another R$25 million in its Mato Grosso property, in order to continue validating the light supplement in new territories!

Eight years ago, Gustavo Alexandre Grossi, a grain producer at Monte Carmelo (MG), noticed that a portion of the soybean crop was growing a lot, but not producing. The third generation of a farming family, he challenged himself to understand the reasons. On a night tour around the farm, he saw that the fastest growing grain was receiving light from a pole on the road that ran alongside the farm.

The use of artificial lights to simulate sunlight and stimulate photosynthesis in plants by emitting an appropriate electromagnetic spectrum, thus compensating or replacing the lack of natural light in certain areas. “I saw that the closer to the light, the more soybean plants grew and grew and did not produce. It was called crazy soybean. On the other hand, the part of the plot that received less light, produced much better than the other areas,” he explains.

“It’s not just light, it’s the right light and the right frequency,” he says.

Grupo Fieline, the project’s author, validated the Irriluce system of luminous central hubs for 14 crops, including sugarcane, cotton, wheat, maize, sorghum, soybeans, beans, sunflower, tobacco, tomato, potato, garlic, onion, and chili.

In the case of soybeans, preliminary research showed up to 57% higher yields with supplementation and a significant reduction in fungicide use. In sugarcane, tests carried out on a farm in Triângulo Mineiro showed that the crops were 20% more productive.

An outdoor lighting supplement technology called Irriluce (for irrigation with light, in Italian) requires an investment of R$15 million over eight years, according to Grossi. It was presented this week by Grupe Fienile, at Agrishow, in Ribeirão Preto (SP). Grossi heads the company, who has a degree in agricultural business and an MBA in environmental management.

Development

Three years ago, Grossi hired researcher Ernan Miranda Lemis, an agronomist with a PhD in soil microbiology, to develop the technology and install LEDs on center pivots. He then set aside 100 hectares of his farm to test the technology in 18 crops, including soybeans, corn, wheat, sorghum, sunflowers, tomatoes, onions, potatoes, cotton, sugarcane and beans. In the experiment, he divided the crops into three areas: one that received supplements every day, one that received it on alternate days, and one that got none.

“We are beginning to understand that light supplements add more or less yield depending on the region, type of soil, climate, management used, type of irrigation, size of fertilizer, etc. Light makes the plant grow and eat more. Without soil analysis, there is a lack of balance in the supplements. We have also seen that every culture They require some kind of light color, intensity, and a certain number of hours of exposure.”

According to Grossi, the best results from supplementation were observed in crops such as soybean, corn, sugarcane, sunflower, wheat, sorghum and potatoes. Lemes, director of research at Grupo Fienile, points out that it is pointless to provide more light if the plant is unable to extract nutrients and water from the soil to grow properly.

The CEO of Fienile does not disclose the cost of the technology, but he does ensure that it is less than the expense of the producer with fertilizers per hectare of harvest without light supplements. Gustavo Grossi explains that the LED modules are mounted on central hubs and that their efficacy depends on aligning the entire production chain well.

In the company’s business model, equipment is loaned for three years, with a package that includes soil and paper analysis, satellite monitoring and agricultural and economic consultancy to the company. In other words, the customer shares data with the company and becomes a partner in developing the technology.

Mild supplementation begins with a consultation with an interested producer to understand what potential limiting factors their region possesses, and what can be improved in terms of management, structure, soil chemistry, nutrition for the plant and the cultivation method itself. Deal with the crop,” he says.

the exams

The producer and entrepreneur says the technology is being used commercially in greenhouses and in the pivotal regions of Minas, Bahia, Mato Grosso and Rio Grande do Sul. It was also tested in different crops in the country.

Filmar Luis Stefanillo, a producer of soybeans, corn and wheat on a 50-hectare farm in Jacuzzinho, Rio Grande do Sul, says he heard about the light supplement three years ago. He spent three days in Monte Carmelo to see firsthand how it works and decided to test it out. “I really got the hub and added the technology to explore the potential of my crop.”

The farmer created his first soybean testing area by applying artificial light to half of his 12-hectare plot equipped with a central hub. He says that, with Fenile’s help, he planted grain on the same day and performed the same cultural treatments in both areas. The result: he harvested 102 bags per hectare in the area that received additional light and 75 in the area without light, the same rate as he did on the farm.

“I made record profits and still spend very little on extra lighting. I thought energy consumption would be high, but it was just a bag and a half of soybeans,” the farmer celebrates, noting that he has been using precision farming on his farm for several years, in search of maximum Efficiency.

According to the researcher, even in years of poor productivity, the technology is very productive and improves the quality of hops, meeting the requirements of the brewing market.

Grossi, CEO of the company, It also plans to test its technology in its own area, of 600 hectares, he bought in Chapada dos Guimarães (MT). He respects Investing 25 million Brazilian riyals in three years. In addition, the company should soon sign a partnership with the Brazilian Agricultural Research Corporation (Embrapa) to validate the system.

Chang Wilches, Embrapa Cerrado Innovation Support Coordinator, confirmed that the partnership has already been agreed and all that is required is a signature. According to him, the research should be carried out in the experimental area of ​​the institution, in Brasilia (DF), in different biomes of Cerrado, for a period of ten years.

“Light crop supplements have great potential. As research progresses, we will validate the versions and do their work,” he says.

hub light for hub

In addition to introducing Irriluce, Grupo Fienile has launched a hub for rainfed areas in Agrishow. The device performs normal axial movements, but does not irrigate water, only light. The goal is to move the light supplement technology to areas that do not have center pivot irrigation that receive a lot of rain and have many cloudy days. Light irrigation will have the effect of preventing or reducing water evaporation from the soil.

According to Grossi, the pivot is only operated on cloudy days and at night and its structure is similar to a pivot, but lighter. There are no water pipes and no motorized pump assembly to pump the water. The chassis will only support the modules, resulting in approximately 30% weight reduction and less energy use. “

The price of the equipment, according to the CEO, is 40%-60% lower than the price of a center pivot.
