It is well to apply the nitrate of soda in two applications a few weeks apart, especially on soils which are leachy and in wet seasons, as part of the nitrogen may leach away if all is applied at once.
But as these soils are apt to be leachy it seems best to fill them with organic matter to as great a depth as possible to increase their water-holding power, and this can best be done by plowing farm manures in deep.
Lands that, on the one hand, are very hard and solid, with a tendency to bake, and, on the other, that are loose and leachy, are very greatly benefited by the addition of organic matter.

Hungry, leachy soils, from their deficiency of vegetable matter and of moisture, do not adequately yield their own native resources to the support of crops, because the conditions for converting their fixed into floating capital are wanting.
If I had my choice between a farm of cold, stiff clay or light, leachy land, I would unhesitatingly take the former, and I would overcome its native unfitness by the following methods: If at all inclined to be wet, as would be natural from its tenacious texture, I should first underdrain it thoroughly with tile.
