The climate is changing. How do we react?

2017.11.07

Many will agree that at present one of the most discussed topics is the changing climate. There are a lot of reasons for the development: from knowledge to scientific discussions and attempts to solve this problem. Scientists say the change is happening. Almost every day we hear about abnormal natural phenomena in one region or another. Several decades ago, meteorological conditions changed depending on the season: winter - snow, the summer was warm and it was practically possible to predict when more rainfall would fall.

 

Scientists often ask questions: why do not we want to recognize what is obvious? Why are we fleeing from reality? Why do not we want to save ourselves?

 

We may think that this is not the case for us, but we can see that economic indicators of some farms are changing due to soil degradation, loss of humus, soil compression, acidification, etc. These phenomena are directly related to climate change and irrational economic activity. The problem is very serious, as the humus soils in Lithuania are only about 10 percent. In non-humane soils, plant productivity is directly dependent on environmental factors, and high costs are incurred for higher yields. It may seem that it is easier for countries with more humic soils to farm. Let's take as an example farmers in the highly developed countries. Let‘s move 2.5 thousand km to the south - the Balkans, specifically Bulgaria. Warm , 600 mm of precipitation per year, soils are humus-like. However, the farmer who met us, who does not consider himself (working 6.5 thousand hectares), will say that farming is very complicated. The farmer said he believed that due to climate change, weather was unpredictable. In the summertime, when the rain began in Lithuania, the thermometer columns rose to 46-50 ° C in Bulgaria. Farmers are used to the hot air of this region, but some surprises are very unpleasant. The heat was accompanied by hail, in some regions it was plentiful, and some dropped the ice cream of the golf ball. What can you expect after that? After seeding rape, the seed yield exceeded 5.6 t / ha, and after the hail, it remained at 0.9 t / ha. Cereals, which were not affected by hail, harvested 13 t / ha of grains and fallen to the genus zone - 6.0 t / ha.

 

How did you succeed in achieving such results? Other farmers can not boast the fertility of such a plant, let alone a year in extreme conditions. The farmer said a breakthrough happened six years ago: "If the results are not satisfying, and you're in favor of the majority, you have to stop and think what you're doing wrong. First of all, we noticed that the soil was very compressed, its pureness reduced, its structure was broken down. Soil was damaged by unnecessarily rushing heavy machinery. Technological park has changed considerably over several decades, the weight of tractors has more than doubled, and soil compression is directly dependent on the intensity of field movement. Other factors are less significant. "

 

The farmer says he does not mind traditional technology. Everyone chooses what looks right to him. I opted for simplified cultivation six years ago, says a farmer, and I see that I'm not afraid. How to choose a tillage method? Everything is simple, if precipitation falls less than evaporates - it goes without saying that it is better to simplify cultivation, because the aim of such technology is to preserve moisture. Wherever the precipitation falls to the extent that it evaporates, any soil tillage can be applied, and where the precipitation falls out more than evaporates, it is better to apply deep purging. It is important to not damage soil structure. In his farm, the farmer decided to work as little as possible on the soil, and some plants are sown directly. Simplified soil cultivation is most consistent with soil laws, because all biological processes take place on the soil surface. The farmer said he noticed that the more intensive the work of the land, the less organic matter remaining in it. Simplifying the cultivation, organic soils began to grow in soil. As examples, several examples have been made: farms with a soil humus content of 8%. and now it is 4 percent; the critical amount is considered to be 2 - 3 percent humus. Only simplified cultivation and the introduction of biological agents into technologies can stop the process of soil degradation. In the course of simplification of tillage and using biological preparations, soil moisture increased by 0.5% over five years. In our case, the most important thing is to preserve the moisture, the fallen precipitates penetrate into deeper layers of the soil, and when working intensively, the water drains off the surface of the soil, the crust forms on the surface of the soil, and the moisture reserves quickly dissipate. Biological products also help maintain effective soil moisture. Think about the bacteria being practically made of water, the more they are, the more effective the moisture.

It should be acknowledged that in the first year costs for plant protection products have increased, but less is spent on fuel. The farmer said that once the biological preparations appeared on the market, they began to use them. The first biological product on the farm was Azofix. Azotobacteria used the activation of plant remnants for mineralization and provision of plants with biological nitrogen. One year later it proved that plant residues are mineralized quicker, soil structure has improved, fertilizer efficiency has significantly increased, fuel costs and plant protection have decreased. Later appeared on Fosfix. It was not by accident that the pH of the soil was 7 to 8 on the Fosfix farm, causing phosphorus to be rapidly bound to soil in forms that were not accessible to plants, high fertilizer rates, and no effect. With the use of Fosfix, the situation has changed, the signs of phosphorus deficiency in corn have disappeared, and after about a year, phosphorus fertilizers have been applied only with seeds. Deciding to use plant protection products more rationally, Bactoforcewas tested. The solution was right, combining chemical plant protection products with biological, it has a great effect. The Nutrilife bioactive plant physiological processor has left the farmer the biggest impression. Fast and clearly visible effect at a low price. The value of the production of cultivated plants is important for each farmer, as it increases with the introduction of biological preparations. The farmer says, "Think about yourself - when you count it all this year, you get tons of wheat at a cost less than 50 euros." Even more sophisticated technology, this farmer will be able to say that he is already prepared for the challenges of a changing climate.
