rve manure like a clay soil. But it is
undoubtedly true that our aim in all cases should be to apply manure in
such a form and to such a crop as will give us the greatest _immediate_
benefit. Plowing under fresh manure every year for wheat is evidently
not the best way to get the greatest benefit from it. But this is not
the place to discuss this matter. Let us look at the result of Mr.
Lawes' experiments on wheat the third year:"

Experiments at Rothamsted on the Growth of Wheat, Year After Year,
