It is of great significance to study the effect of different planting patterns on the maintenance of soil nutrients in slope farmland. Compared with planting soybeans, the available phosphorus content of the 2° and 5° test fields increased by 17.89% and 21.02%, respectively, and the 3° test field decreased by 7.87%. In the experimental field for planting soybeans, the average effective potassium content decreased with the increase of slope, and the content of 0-10cm soil layer was higher than that of 10-20cm soil layer. Different planting patterns led to differences in the distribution of available phosphorus and available potassium, but the content of 0-10cm soil layer was higher than that of 10-20cm soil layer.
