Experimental plantings, matching various rootstocks with representative 

 Massachusetts soils, are presently being conducted throughout Massachusetts 

 but no definite results on yield differences are available as yet. Based on 

 past experience we can make some general recommendations regarding the per- 

 formance of certain rootstocks on various Massachusetts soils. 



The first step in matching the rootstocks and soil is to determine the 

 soil type{s) for the land to be planted. Soils information generally is 

 available from the U.S. Department of Agriculture - Soil Conservation Service 

 office in the form of soil survey reports. If no soil map is available, an 

 on-site inspection by a qualified soil scientist will provide the necessary 

 information. On-site investigations often are preferred because localized 

 wet or droughty spots may exist within fields that are otherwise well suited 

 to apple production. These less desirable areas may be too small to be 

 indicated on the standard scale soils map. Your local Extension Service 

 office can provide you with the names of qualified soil scientists within 

 your area. 



The soil series currently recognized in Massachusetts have been grouped 

 in 6 soil suitability groups (Table 1). Keep in mind that these suitability 

 groupings are based on internal soil characteristics. External properties 

 such as landscape position and a drainage potential are not considered, 

 therefore, soils at certain locations, although placed in a favorable 

 grouping, may not be suitable for apple production. 



Lastly, refer to the tentative guide for rootstock/soil compatibility 

 in Table 2 to determine which rootstocks are most suitable for your soil 

 conditions .
