APPLYING FERTILIZER WHEN
PLANTING.
While Il Is certainly true, in our ex,
perience, that the greater part of the fer
tilfzer should be applied about two weeks
mixed in the soil Of the bedding furroV
and bedded on, there ara circumstances
that would justify a farmer in nakini
one or more intercultural applications
including one at the actual date Of plant
ing. The following are such circumstaA
ces:
al When a farmer has not been abb
to secure the whole amount Of his fer
tillzers before planting time.
CT When he concludes, after his GRO
has been planted and is growing, tina
he did not buy and apply as much as b
should have done before planting.
go When the yellowtsh green color an
want of vigor in the appearance of tn
plants indicate that more nitrogen
needed by the crop.
We believe it may be safely accepte
as a general rule that small porto
