Many farmers follow the recommended fertilizer rates and achieve satisfactory results, so they tend to stick to traditional methods because they seem reliable to them. This is especially true for smaller farms, whose owners believe that the cost of soil testing is not necessary. Recommended fertilizer rates are often based on long-term research and can be accurate enough for many farmers. However, without knowing the true condition of the soil, it is possible to over-fertilize or under-fertilize, which can have a negative impact on both yield and cultivation costs. The Nutricheck project in the K?dainiai Farmers' Nutrition Club (CNC) fertilization of winter wheat, assessing the amounts of applied fertilizers and nutrients (NPK) accumulated in plants, showed that when fertilizing at the recommended rates, plant nutrient uptake was lower than when fertilizing based on soil tests. When fertilizing at the recommended rates, N uptake in winter wheat was 80 EUR/ha, phosphorus – 58 EUR/ha, and potassium – 131 EUR/ha lower than when fertilizing winter wheat, taking into account the nutrients in the soil.
