Importance of soil testing during periods of high fertilizer prices
So many farmers mistakenly think that trying to cut input costs by skipping the checking and testing of the soil before the crop is more wasteful when fertilizer prices are high.
Annual soil checking and testing to see how much nutrients the soil needs to change, depending on seasonal factors such as crop type and growing season rainfall is always appreciated by soil scientists. Especially in the context of the current high prices of fertilizers, as well as input materials for production, a balanced fertilizer application is a perfect solution.

Accordingly, scientists recommend that farmers trying to reduce costs by skipping soil testing and testing this fall could lead to the risk that it will be more expensive for input materials. next season 2022. It is a fact that many people still mistakenly believe that the more fertilizer the better. However, in fact, plants can only absorb a certain amount of fertilizer, once this amount exceeds the assimilation capacity of the soil, they will follow the surface runoff to neighboring ponds and lakes.
For example, this year, the amount of nitrogen in the fields may be more applied by farmers because the 2021 crop will grow in hot and dry weather, so the plants cannot absorb and use nutrients as much as normal crops.
Eutrophication, also known as algal blooms, is the leading cause of deterioration of coastal and aquatic ecosystems, threatening to destroy natural freshwater and aquatic resources. Photo: Vietnam Agriculture Newspaper - PBS.
Excessive fertilizer application causes eutrophication. This is an ecosystem response when too many nutrients such as nitrates and phosphates from fertilizers or sewage are released into the aquatic environment.
Normally, when nitrogen (N) content is greater than 500 µg/l and phosphorus (P) is greater than 20 µg/l in water, it is considered eutrophication. The most common and obvious evidence is that water sources experience "algal blooms" or spikes in phytoplankton as the number of nutrients in the water increases.
This phenomenon negatively affects the environment such as lack of oxygen, depleting dissolved oxygen in water, reducing the number of aquatic resources and other animals as well as polluting domestic water sources.

Soil analysis, soil quality assessment and fertilizer recommendation Service at Eurofins Sac Ky Hai Dang - Solutions for optimizing fertilizer use
It is because the farmers do not have the tools to know how to fertilize enough, leading to wasted money, degraded soil, reduced soil health, making productivity and quality of agricultural products gradually decreased. Further, there are negative effects on the environment and the health of consumers.
Eurofins Sac Ky Hai Dang always accompanies businesses and follows the policies of the State, towards a sustainable, high-yield and efficient Agriculture industry. With modern, innovative and reliable technologies, our Soil analysis, soil quality assessment and fertilizer recommendation Service, the top service in the chain of AgroScience services in Eurofins Sac Ky Hai Dang, is the solution to help optimize the use of fertilizers, learn more about methods of fertilizer and soil management to maintain or improve soil fertility for sustainable agricultural production.
Soil analysis, soil quality assessment and fertilizer recommendation Service
We use Near-Infrared Spectroscopy (NIRS) technology for soil analysis. This is considered as a green technology with competitive cost: very fast technique, non-destructive, optimizes sample preparation time, etc. Moreover, this technique was developed and delivered by Eurofins Agro Wageningen Netherlands, with nearly 100 years of experience, obtaining a very large dataset in soil analysis by both conventional methods and NIRS technology, bringing to the accuracy and reliability of our services.
