b = charcoal(to be labelled)

d = garden soil
e = dillute hydrochloric acid(to be labelled)
f = 250cm measuring cylinder

AGRIC FULL PRACTICAL ANSWERS
A = wood ash | chemical compound = Ca4(PO4)2 SiO4 it is a lime chemical
B = charcoal | source = burnt wood
C = limestone | chemical compound = CaCO3 | use as lime
advantages of b and c
1 : improve the soil structure
2 : increase microbial activities
3 : increases organic matter breakdown
4 : reduces soil ph
5 : enhances the movement of water and air in the soil

effacts of excess of a , b and c
1 : decrease the activity of soil microbes
2 : changes soil ph
3 : differencies of iron , magnessiu$ and copper
4 : inhibit absorption of boron
5 : decreases the soil phosphorus
there is more specimen
specimen f = measuring cylinder
pour the garden soil in a measuring cylinder and add hcl acid to it the soil becomes acidic as it turns blue litmus red
in summary any substance that turns blue litmus paper to red is an acidic substance but if it turn red litmus blue it is an alkaline
causes of soil acidity
1 : leaching
2 : use of acid fertilizer
3 : accumulation of hydrogen ion in the soil
4 : heavy rainfall
5 : present of sulphur in soil
6 : purification in a watet logged soil
