Effect of Biochar and Bentonite Application in Availability and Uptake of N, P and K for Faba Bean in Desert Soil
2023
Overview
A field experiment was carried out to evaluate effect of some soil conditioners (biochar and bentointe) in availability and uptake of N, P and K for Faba bean in desert soil. The study included four levels of biochar (Seek) 0, 10, 20 and 30 Mg ha-1 ( S0, S1, S2 and S3) and four levels of bentonite 0, 10, 20 and 30 Mg ha-1 (B0, B1, B2 and B3). The experiment was carried out according to randomized complete block design (RCBD) with three replicates were used. The results indicated that the application of biochar and bentonite significantly affected in nutrients availability and uptake under study. The forth level of biochar and bentonite gave the highest values of N, P and K availability reached 67.79, 16.60 and 202.69 mg kg-1 soil for N,P and K availability, respectively for biochar and 66.83, 15.49 and 184.57 mg kg-1 soil for bentonite. The results showed also that the fourth level of biochar and bentonite gave the highest values of N, P and K uptake reached 45.64, 12.53 and 23.82 kg ha-1, respectively for biochar and 47.97, 11.86 and 22.71 kg ha-1, respectively for bentonite. As for the interaction between two amendments the treatment (S3B3) was the most efficient in giving the highest values for available N, P and K it reached 72.43, 20.53 and 217.13 mg kg-1 soil, respectively and nutrients uptake reached 55.97, 14.94 and 32.14 kg ha-1, respectively.
