| The experiments conducted in the mountainous region of south Ningxia showed that BP aquasorb was effective in conserving soil moisture, improving nutrient condition and increasing crop yield. By applying BP aquasorb to the field of wheat, corn, pea and potato, the soil moisture content was raised by 7.95%12.13%, and the yield was increased by 8.25%12.19%. Therefore, BP aquasorb is an effective way to resist drought and to increase crop production in arid areas. |
