Pot experiments were carried out using sand (collected from Ismailia ARS), in the greenhouse to study the effect of biochar application, on K and P release from their natural bearing minerals i.
e.
, K- feldspar and rock phosphate andor bentonite on some growth of maize plants parameters, their P and k uptake and the soil available P and K.
sixty three pots ever filled with sand(10 kg each biochar was added to all pots expect control at rates 0, 1.5, 3 ton per fed.
The studied mineral are K feldspar and rock phosphate as source of K and P respectively.
Bentonite was also studied because it is the most common mineral used for reclamation of sandy soil.
Each mineral was added at rate of 0, 1.5, 3 ton / fed the pots are as follow: biochar alone, biochar + K feldspar and biochar +bentonite and biochar and rock phosphate.
maize was planted as the common way in which maize seed 6 grains for each pot inoculated with P and K solubilizing bacteria were planted.
the usual N fertilizer (NH4 )2SO4 200kg /fed and irrigated as needed.
Maize grow parameter i.
e plant height and dry weight of maize plant were measured after 2 months of plantation.
K and P as well as their uptake were measure.
Results revealed that, the use of biochar at 3 tons fed-1 in combination with 3 tons of any of feldspar, bentonite or rock phosphate enhanced significantly growth parameters of maize plants compared to the control treatments.
The highest values plant length and dry matter were were 89.00 cm, 11.4 g pot-1 against 36.6 cm and 2.8 g pot-1 for the control treatments.
, same treatments increased significantly P and K uptake of maize plants and the soil available p and K compared to the control treatments.
The highest significant values in P uptake were 22.5, 18.3 & 16.7 mg plant-1 for the treatments (3 tons fed-1)of biochar with either 3ton rock phosphate, 3ton bentonite or 3 ton K-feldspar.
while K uptake were 63.9, 61.8 & 60.1 mg plant -1 for biochar ( 3 tons fed-1 )with bentonite (3 tons fed-1 ), feldspar (3 tons fed-1 ) and bentonite (1.5 tons fed-1 ).
Regarding available P the highest obtained values were 49.3 mg Kg -1 for 3 ton biochar + 3ton rock phosphate, 24.1 mg Kg -1 for 3 ton biochar + 1.5 ton bentonite and 24.0 mg/ kg-1 for 3 ton biochar + 1.5 ton K- feldspar.
Increase either K- feldspar or bentonite to 3 ton had negative effect on available p.
