Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Microbial fuel cells 09.12.2012

An unexpected source of new, environmentally friendly energy has been found - a microbial fuel cell plant that can generate electricity from the natural interaction between living plant roots and soil bacteria, that is, extract electricity from the most ordinary swamps. This technique is already being used, but so far on a small scale. And soon it will be used everywhere in large wetlands around the world.

The microbial fuel cell plant draws electricity from the soil while the plants continue to grow. Plants produce organic matter through photosynthesis. The roots release up to 70% of this material into the soil. And all this remains unused and literally disappears into the ground. Bacteria around the roots decompose organic residues, thus forming a new source of electricity. Degradation processes release electrons. Researcher Marjolein Helder and her colleagues placed electrodes among bacteria to absorb these electrons and thereby generate electricity using potential differences.

A microbial fuel cell plant can currently generate 0,4 watts per square meter of swamp turf. This is more than what is created by the fermentation of biomass. In the future, bioelectricity from a plant will be able to produce 3,2 watts per square meter of green mass. This means that a 100 m2 plot, placed on a flat roof, will generate enough electricity to power household appliances in the house at an average consumption of 2800 kWh per year. Various types of plants can be used, including herbs as common as English cordgrass, and in warmer countries, rice.
