AGRICULTURAL ECONOMICS 



An Inventory of Land Improvements Needed 



Improved field practices and tractor equipment cannot be used to 

 the best advantage where operations are handicapped by stone cross 

 fences, large stones, ledge outcrop, or wet areas. In October, 1944, 

 dairy farmers of Belmont were interviewed with reference to possible 

 improvements of tillage land that might be made on their farms in the 

 postwar period. 



The 27 dairy operators reported a total of 1369 acres of tillage land 

 of which 1143 acres were classified by the operator as good crop land. 

 The remaining 226 acres were called permanent hay land. According 

 to the estimates by these farmers, there A\as a total of 1135 rocks, 19,005 

 linear feet of stonewall, 19 small areas of ledge, 22 old apple trees, sev- 

 eral piles of small rocks, and numerous wet area which, at present, im- 

 pede cultivation. Over 12,000 feet of ditches and tile would be re- 

 quired to drain these \\et areas. The stonewalls and rocks on the fields 

 totaled approximately 14,000 tons for the 27 farms. 



About 40 per cent of the operators were interested in making some 

 of the needed improvements, and three already had undertaken minor 

 clearing projects. The survey indicates that many aggressive operators 

 will want to make improvements in this crop land, especially if a plan 

 can be developed to make special machinery available. 



Major improvements needed in barns, water supply, and in the 

 homes were also inventoried.
