Crop residue mineralization becomes important topic

Progress - Harvesting has not begun yet, but farmers already are interested in the mineralization of plant residues. The aspiration of farmers - strong and viable plants. Farmers should be aware of the impact of this fertilization when planning winter pasture in autumn. Is it intended to encourage the degradation of residues, whether it is intended to influence the growth of plants, or whether it is considering increasing nitrogen in plants and soil, which would ensure a better start of plants in the spring. In each case, the farmer has to think about different fertilization methods, fertilization rate, fertilization time and think the most about nitrogen fertilizer forms.

The main problem is that the plants that begin to grow begin to "fight" with the microorganisms due to nitrogen in the soil. To ensure decomposition of plant residues, farmers apply nitrogen fertilizer on straws, which later are mixed to the soil. But do farmers think about what type of nitrogen fertilizer to choose? Nitrogen must be in the form of ammonium (NH4) because nitrate (NO3) microorganisms do not use in practice. It would be best to use ammonium sulphate or in livestock farms - slurry. How is in reality? In most cases, we have heard suggestions to increase Ammonium nitrate rate, which means that the money spent will go to the groundwater. When considering what to do, we think that rubbing or spraying nitrogen fertilizer on the straw is irrational and not up-to-date. As a result, Bioenergy LT consultants recommend to spray straws with combination of Ruinex and Azofix. Azotobacter synthesizes nitrogen and provides nitrogen to organic residues degradating microorganisms. Also, the research results have shown that the combination of these products initiates the accumulation of nitrogen in the soil, which means that the plants will have it even for the spring start.

Some farmers, after seeing poor winter crops, give up and  apply nitrogen fertilizers after the sowing. It goes without saying that there will be a problem with straw decomposition. Especially where the straw is deeper inserted into the soil. Even the ammonium sulphate is removed, by joining a layer of straw containing the soil absorbing complex to reach nitric acid. This means that it will be a nitrogen-free form that does not affect straw decomposition. Someone recommends urea, but the main condition for its use is necessary precipitation, it can dissolve, but it will take time. The farmers who apply urean, say that they are trying to improve nitroten content in the soil. However, the period from fertilizer application to soil saturation with nitrogen - an average of two months (NH4 turns into NO3). Naturally, straw destruction will not work, and nitrogen will only be used for plant growth.

We recommend the following scheme: if, in the course of vegetation, the plants was sprayed with Azofix after harvest, we recommend spraying the plant residues with a combination of Ruinex and Penergetic K. If Azofix is not used during the growing season, we recommend the combination of Azofix, Penergetic K and Ruinex. There are cases when wheat is picked up or sown after an inappropriate pre-cropr, or very common root disease, then we recommend adding Bactoforce to Ruinex. Each case is individual and the problem needs to be addressed individually, taking into account local conditions. We also recall that, in the case of rough agrotechnical mistakes, biological preparations will not be as effective. For example, after harvesting, biological products applied and plought at a depth of 20 to 25 cm, it is understood that the expected effect will not be reached, but it is better than covering the whole untreated straw.

Ruinex is the first step to improve soil properties and increase farm profitability.
