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 ... >>

Leaf cutter ants produce laughing gas 15.01.2019

The impact of agriculture on the environment is often underestimated. At first glance, it seems that what a cow peacefully grazing in a meadow or a chicken pecking at grain can do with nature compared to smoky factory chimneys? One chicken, of course, will not bring noticeable harm. But a medium-sized poultry farm, where the number of such chickens is estimated in tens of thousands, can already become a large source of ammonia, which is released from chicken manure.

Therefore, in order not to poison the neighborhood with poisonous gas, special ammonia collection and disposal systems are installed on poultry farms, and the chickens themselves are fed with special feeds that reduce the “ammonia content” of their droppings.

However, agriculture is not limited to humans. One of the most advanced farmers who launched active activities long before the appearance of man is leaf-cutting ants. Representatives of two ant genera, Atta and Acromyrmex, have learned to cultivate mushrooms, supplying them with a nutrient substrate - chewed leaves. Mushrooms eat leaves, ants eat mushrooms, and they all seem to be fine. But like us, ants have a waste problem. All that remains from highly organized activity, and these are mostly leaves that have begun to decompose, are thrown by ants into a kind of trash cans, in which the biomass is already completely rotting.

It turned out that such compost heaps are capable of releasing large amounts of nitrous oxide (N2O), known as laughing gas, into the atmosphere. The intensity of emissions of this gas from ant landfills can be several orders of magnitude higher than the average from rainforest soil.
