Combooster Aktivointiliuos — New fertilisation method

What if you could save on fertiliser costs without compromising on yield? Would you like to leave more carbon in the soil without major action? With Combooster Aktivointiliuos, you can significantly increase nitrogen utilisation so that markedly less soluble nitrogen is required and more carbon is left in the soil. With Combooster Aktivointiliuos, you can also get more out of organic fertilisers, as the increased microbial activity in the soil breaks down organic nitrogen into a usable form for plants.

New fertilization system

How does Combooster Aktivointiliuos work?

Combooster Aktivointiliuos increases the yield production of grasses and grains by boosting nitrogen uptake from the soil, slurry fertilisers and other nutrient sources containing organic nitrogen, aided by the field’s natural soil microbes.

  1. Optimal microbial activity occurs when a smaller than usual amount of soluble nitrogen is given during the first fertilisation, along with Combooster Aktivointiliuos.
  2. The microbes convert the organic nitrogen in the fertiliser into a usable form for the plants immediately at the start of the growing season. If necessary, supplementary nitrogen fertilisation can be given later during the growing season.
  3. The nitrogen utilisation rate increases and humus synthesis activates. The field’s carbon balance remains positive as the organic nitrogen has already been utilised in the first half of the growing season and there is no excess nitrogen causing the usual priming effect post-growing season, which often causes emissions in waterways.
  4. Soil fertility improves.

Manufactured by Biokasvu Oy

What is Combooster Aktivointiliuos?

Combooster Aktivointiliuos is a product manufactured by Biokasvu Oy and based on a patented invention. Combooster Aktivointiliuos is a water-soluble plant biostimulant (not a microbe-based biostimulant) that can also be used for organic production. The product’s raw materials are sugars in mixtures (molasses and vinasses), which naturally contain primary nutrients and micronutrients, plus natural amino acids.

The significance of microbial activity in soil for the growth of cultivated plants

Microbial activity in soil is extremely important for the growth of cultivated plants. Microbes, such as bacteria, mushrooms and archaea form a complex ecosystem in the soil which has a positive effect on plants’ nutrient uptake, health, and growth. Here are some reasons why microbial activity in soil is important for cultivated plants:

1. Nutrient breakdown and availability: Microbes break down organic matter in the soil, such as plant waste and animal droppings. This decomposition process releases nutrients into the soil, such as nitrogen, phosphorous and potassium, which the plants can utilise. Microbes therefore act as nutrient recyclers, which improves the availability of nutrients for plants.

2. Improving soil structure and ventilation: Microbes promote the formation of soil structure by producing binding agents that help soil particles to join together. This improves the porosity, water absorption, and ventilation of the soil. Good soil structure enables root growth and facilitates nutrient uptake.

3. Disease prevention: Certain soil microbes can be useful to plants because they compete with pathogens or produce antimicrobial compounds which prevent pathogens from growing and spreading diseases. This helps to protect the plants from diseases and reduces the need for chemical pesticides.

4. Oxidation processes: Microbes participate in soil oxidation processes, such as nitrogen fixation and denitrification. Nitrogen-fixing bacteria are able to convert atmospheric nitrogen into a form that is usable by plants. Denitrifying microbes meanwhile reduce nitrogen in the soil in nitrate form, releasing it into the atmosphere. These processes are important for the nutrient cycle and for nitrogen utilisation in cultivated plants.

5. Stress tolerance: Microbial activity in soil can help plants to cope with stress-inducing conditions, such as drought, salinity, and temperature fluctuations. Certain microbes can improve a plant’s stress tolerance by producing hormones and other materials that help the plant to survive in challenging environmental conditions.

6. Microbial activity in soil is therefore an essential component of soil health and cultivated plant wellbeing. Sustainable farming practices, such as adding organic matter to the soil, avoiding excessive tilling, and the controlled use of chemicals, can support microbial activity in soil and promote plant growth and production.
