Soil conditions affect sugar beet fertilization mainly include the following aspects: the impact of soil pH. First of all, soil pH affects the choice of fertilizer type, in acidic soil should choose physiological alkaline fertilizer, on the contrary, should choose physiological acidic fertilizer. Secondly, soil nutrient effectiveness determines the effectiveness and abundance of certain nutrients in the soil. In soil pH 7 to 8, trace elements boron, manganese effectiveness is the lowest, the soil is easy to lack of these two elements. When the soil pH 7 to 8.5, the effectiveness of phosphorus in the soil is the lowest, and the soil is prone to phosphorus deficiency. The effect of soil texture. On sandy soil, soluble boron is easy to leach, and the chance of boron deficiency in sugar beet is greater. In addition, the soil texture affects the fertilization method, on the clay soil with good fertilizer retention, the amount of base fertilizer and seed fertilizer can be increased; on the sandy soil with poor fertilizer retention, the amount of base fertilizer and seed fertilizer can be appropriately reduced to increase the amount of fertilizer and the number of times of follow-up fertilizer. The effectiveness and storage of soil nutrients themselves.

The effectiveness and reserves of nutrients in different soil types vary greatly, and the proportion of the effectiveness of different nutrients is not the same, and the absorption of various nutrients by sugar beet is in a certain proportion. Therefore, according to the soil nutrient status of sugar beet fertilizer, such as in the black soil area, the ratio of the three elements according to the N: P2O5: K2O for 1.5: 1: 1; in the carbonate black calcium soil area, N: P2O5: K2O for 1: 1.5: 1. Planting sugar beet is more ideal soil conditions: neutral or weakly alkaline (pH 6.5 ~ 7.2) loam or sandy loam; the tillage layer of more than 20 cm; Higher organic matter content and more effective nutrients; good drainage; and a water table below 1 to 1.2 meters. Clay soil has poor permeability, slow ground temperature recovery, organic matter is not easy to decompose, prone to beet root rot, planting sugar beet should be more organic fertilizer, deep turning, deep pine, improve soil structure. Sandy soil permeability is good, easy to plow, the ground temperature rises quickly, is conducive to seedling and tuber growth, but sandy soil water retention, fertilizer capacity is poor, easy to de-fertilization, should be timely irrigation, more organic fertilizer, timely fertilizer, and strengthen the management of plowing. Sugar beet is not very strict on soil acidity and alkalinity requirements, the most suitable soil pH is 7.0 ~ 7.2. In general, in the range of pH 5.0 ~ 7.2, tuber yield increases with the improvement of pH. Sugar beet yields are lower when the soil is too acidic or too alkaline. The deeper the soil tillage, the more favorable the growth of sugar beet tubers.
