Fountas, K. Aggelopoulou, C. Bouloulis, G. Nanos, D. Wulfsohn, T. Gemtos, A. Paraskevopoulos, M. Galanis] Yield and soil mapping were carried out in 2007 and 2008 in a 9.1ha commercial olive tree plantation for olive oil production. The orchard is in the southern Peloponnese, where olives are cultivated extensively for extra virgin olive oil production. The field is planted in rows with about 1650 trees in total. Weed control was practiced during the previous 3years using post emergence herbicides under no-tillage over about 2/3 of the field, and over the remaining 1/3 by mechanical weeding using a rotary cultivator. For yield mapping, olives were collected manually using rods to shake the tree shoots and letting the olives fall onto a plastic net covering the ground. Sacks of approximately 58kg capacity were filled with olives from as many adjacent trees as were needed to fill a sack. The location of the sacks, or group of closely placed sacks, was identified using a commercial GPS (5m resolution). In addition, 91 cores of soil were taken at a depth of 0-30cm on a 30-m systematic sampling grid corresponding to a density of 10 soil samples per ha. The soil properties measured were penetration resistance, soil texture, organic matter, pH, P, NO3-N, K, Mg, Zn, Mn, Fe, B and Ca contents. The effect of the method of weed control on the soil condition for post emergence herbicides under no-tillage versus rotary cultivation was evaluated on the basis of soil organic matter content and penetration resistance. The data were analyzed using both descriptive statistics and geostatistical methods. Maps were created as a basis for site-specific management of P, K and lime, and these were applied 15days after harvest in the winter of 2008. The results indicated considerable spatial variation in yield and soil properties. The soil organic matter content was about 22% greater and the penetration resistance about 26% less in the areas under no-tillage. The mean pH increased from 5.9 to 7.0 as a result of lime application in the areas with pH below 6.5.
