Abstract: With the systematic technique, all macro-, secondary- and micro-nutrients are considered in soil nutrient status evaluation and fertilizer recommendation, so that all nutrients are supplied in a balanced manner. In the soil testing, multi-nutrient extraction solutions were used, a semi-automatic operation procedure and soil data management system and fertilizer recommendation program based on web technique were developed which significantly improved the working efficiency of the laboratory. Based on the soil testing results for more than 40 000 samples and more than 7 000 field trials, a database, a data management system and a computerized fertilizer recommendation system were established which is applicable for main farming soil types and crops in China. The fertilizer recommendation models for more than 100 crops improved their balanced fertilization for high yield and high quality. The high efficient equipments for soil testing were exploited and produced which could improve the soil testing and fertilizer recommendation and have a great benefit and achievement.
