Tillage and Planting Cost Comparisons Jayson K. Harper Professor of agricultural economics Department of Agricultural Economics and Rural Sociology The Pennsylvania State University, USA Penn State is committed to affirmative action, equal opportunity, and the diversity of its workforce
Three systems to compare • Conventional tillageinvolves disking, plowing and other methods of tilling up crop residue left behind after harvest. • Conservation tillageis any method of soil cultivation that leaves the previous year's crop residue on fields before and after planting the next crop, to reduce soil erosion and runoff. To provide these conservation benefits, at least 30% of the soil surface must be covered with residue after planting the next crop. • No-till planting methods eliminate tillage entirely and leave 70% residue or more.
Advantages of Conventional Tillage Buries crop residue Aerates the soil Provides mechanical weed control Incorporates fertilizer
Advantages of Conservation Tillage Lowers fuel cost Lowers labor requirements Reduces machinery investment Reduces soil loss Conserves soil moisture Less soil compaction Improved timeliness

So…how can farmers afford to change planting systems? • Equipment rental or sharing • Dealer, government agency, farmer cooperative • Custom operator (hired service) • New technology without investment • Higher efficiency, improved timeliness • Retrofit existing equipment • Government conservation incentives? • Equipment cost share • Crop consultancy cost share • Cover crop subsidy/green farming incentives
Summary • Conservation tillage has many production advantages over conventional tillage • Depending on the on-farm availability of labor, management, and capital, conservation tillage may have significant economic advantages over conventional tillage • Encourage farmers to use available farm management tools to help determine the economic benefits on their farming operation • Enterprise budgeting (cost of production) • Machinery cost analysis • Partial budgeting
