SOIL ANALYSES AND COMPUTERIZED FERTILIZER RECOMMENDATIONS FOR VEGETABLES IN PENNSYLVANIA
Soil analysis starts in the field and poor sampling habits will bring bad results. In Pennsylvania the grower has to take his own soil samples according to recommended procedures. He has to buy, at the county agent's office, a so-called mailing kit which costs $ 2.00. This kit contains a mailer, plastic bag for the sample, and an information sheet (Table 1) to be filled out by the grower. On the back this information sheet is another questionnaire (Table 2), in case of previous crop problems, must be filled out as a help in arriving at recommendations. A carbon paper and second page are attached to the information sheet serving as a grower's copy. On its back soil sampling instructions are given.
