Bamboo Biochar and a Nopal-Based Biofertilizer as Improvers of Alkaline Soils with Low Buffer Capacity

Alkaline soils with low buffering capacity are susceptible to amendments such as biochar or biofertilizers, which could drastically alter their pH. For that, this study aimed evaluate the effectiveness of a and biofertilizer addition improve soil characteristics use nutrients reduce doses chemical fertilizer. we measured initial effect on characteristics. Then, changes produced by cultivated soil, carried out greenhouse experiment Physalis ixocarpa for two crop cycles. We also studied nutrient efficiency, comparing fertilization at 100% (without biochar) against 50% 20% yield, plant height, fruit weight, root length. Finally, compared combination treatments mentioned earlier. The results showed that after adding 0.2% bamboo biochar, bulk density (BD) decreased while CEC, well OM, Pav, Fe, Cu contents, increased in soil. improved WHC, OM added biochar. found nopal-based fertilizer suitable improvers
