Mineral fertilizing in the spring is applying, first of all, in floodplain and lowland areas (flood meadows), as well as in the processing or digging of the soil. Before you apply mineral fertilizers to the soil, it is important to correctly calculate the amount of fertilizing, avoiding overdose, in the first place, nitrogenous fertilizing.
In the middle regions with high precipitation, so that fertilizers do not wash out, it is better to introduce them in the spring when the soil is cultivated (the third part of potassium-phosphorus fertilizers and all nitrogenous fertilizers).
In autumn, is applying fertilizers more resistant to leaching: lime, phosphoric flour, ammonium sulfate, granular superphosphate or ammonium chloride.
Most often (though not always) it is more useful when both mineral and organic fertilizers are simultaneously applied to the soil. In this case, the dosage of mineral fertilizers should be reduced by about one-third of the normal application rate.
