The E.C. and soluble salts ae OK There is no excess carbonates The low percolation indicate water move slowly throught the soil. Care must be taken not to over irrigate and induce phytothtpora rot root Nitrate nitrogen is low which is normal for this time of year. Phosphorus is normal , no phosphorus needed The potassium is low in the Shop East sample and just in the normal range for the West Shop sample. The magnesium is very high in both soil samples, magnesium depresses the uptake of potassium. As the trees are beginning to bear suggest 500 pounds per acre of potassium sulfate per acre as a band in the drip line The calcium levels are low in both samples. Suggest two tons of gypsum per acre to increase the calcium content. The extra calcium should help the drainage of water in the soil and the areation of the soil. The magnesium levels are very high and contribute to the stickiness of the soil and its low percolation Sodium is OK The boron is very low. Suggest boron in the herbicide spray The zinc is very low, Suggest EDTA zinc at 2 quarts per acre in one of the nitrogen applications next spring Iron, copper, manganese and sulfate are probalbly OK Suggest a leaf analysis next July to assess the balance of the major and minor nutrients. Any necessary additions to the fertility probram can be made at that time. I Page 1 of 2 t
