ABSTRACT Apparatus for distributing a chemical substance in agricultural land at below surface level, say, l metre below. The apparatus includes a hopper (10,114) for the substance, a blower (16,146) for feeding material from the outlet of the hopper into a down- pipe (48,1441, and an agitator (88,132) for preventing packing in the hopper. A shank (26) has an earthworking implement (30) at the lower end thereof for lifting the ground and breaking-up subsoil clods but not turning the soil over. The implement has an aperture (40) in it rearwardly of the shank (26), and the downpipe leads to this aperture so that said substance is discharged under pressure below said implement, the pipe lying rearwardly of the shank. Under the hole there is a plate (42) on which down-flowing substance impinges and which scatters it laterally. The substance can flow from the hopper into the blower and then out of the blower outlet into the downpipe. Alternatively, the substance can flow into the upper part: of the downpipe and air can be blown into the downpipe so as to suck the chemical substance from the upper part of the downpipe into the lower part, and then discharge it under pressure below the implement.
