Page 44 - These soils have in the surface 8 inches approximately 2000 pound of phosphorus per acre ; from 30,000 to 40,000 pounds of potassium ; and approximately 10,000 pounds of nitrogen. Since they are surrounded by highland, the subsoils of which are rich in ground limestone which is being continuously dissolved and carried to the lower lands by percolating waters, they are as a rule not acid, and in fact usually contain considerable quantities of lime carbonate.
Page 83 - The rainfall is normally well distributed throughout the growing season.

Page 168 - Among the factors which influence the agriculture of a state, none is more important than climate. The class of crops which can be grown is largely determined by the length of the growing season, and the amount and distribution of the rainfall.
Page 40 - ... more, depending upon the degree of acidity. The limestone may be applied at any convenient time as it is slowly soluble and will remain in the soil for a number of years.
