﻿THE RESEEDING OF DEPLETED GRAZING LANDS. 5 



THE GENERAL STUDIES. 



These were initiated in 1909 and continued in 1910 and 1911. The 

 tests were confined to plots averaging 4 acres, selected as representa- 

 tive of general conditions. Progress reports on the experiments were 

 submitted at the close of each growing season. 



SPECIES SOWN. 



The following 14 grasses and 8 species other than grasses were 

 tried in the experiments: 



(IRASSKS. 



1. Broom grass (Andropogon sp.). 



2. Canada blue grass (Poa compressa). 



3. Slender wheat grass (Agropyron tenerum). " 



4. Blue grama grass (Bouteloua oligostachya) . 



5. Hard fescue (Festuca duriuscula). 



0. Italian rye grass (Loliiim itaUcuni). 



7. Kentucky blue grass (Poa pratensis). 



8. Mesquite (Hilaria cench reticles) . 



9. Orchard grass (Dactylis glomerata). 



10. Perennial rye grass (Lolium perenne). 



11. Redtop (Agrostis alba). 



12. Smooth or Hungarian brome (Broms inermis). 



13. Tall meadow oat grass (Arrhenatherum elatius). 



14. Timothy (Phi en m pra tense). 



NONGRASSES. 



1. Alfalfa (Medicago sativa). 



2. Alfilaria (Erodium cicutarium) . 



3. Alsike clover (Trifolium hybridum). 



4. Australian saltbush (Atrvplex semibaccata) . 



5. Bur clover (Medicago denticulata). 



6. Japanese clover (Lespedesa striata). 



7. Red clover (Trifolium pratense). 



8. White clover (Trifolium repens). 



In the above list the 10 species most frequently employed in 449 

 experiments, either sown singly or in mixtures, as reported in the 

 year 1911, were as follows:

CULTURAL METHODS. 



Owing to the difficulty of transportation in many localities, and to 

 the expense involved, the seed, was sown broadcast and the soil 

 treatment resorted to in most cases consisted of inexpensive methods
