Strawberry (Fragaria X ananassa Duch.) yiel das affected by the soil pH

Abstract

Two-year trials (2006)(2007) suggested that the use of calcium oxide (CaO) on acid soils increased soil pH and yields in strawberry cultivars Marmolada, Selena and Senga Sengana, under the environmental conditions of Cacak (Western Serbia). The highest yield was obtained when CaO was applied at 750 kg ha -1 rate. Further increase in rate up to 1,500 kg ha -1 did not show corresponding increase in yield; the result was a slight yield drop compared to the peak yield shown at 750 kg ha -1 rate. Overall, yields at rates above 750 kg ha 1 were still higher than control and in the treatment employing lowest CaO application rate of 250 kg ha -1 .

Yield, Quality, and Nutrient Concentrations of Strawberry (Fragaria ×ananassa Duch. cv. ‘Sonata’) Grown with Different Organic Fertilizer Strategies

“…The higher root zone pH could be responsible for the lower fruit yield in the organic treatments because it influences root growth and nutrient solubility/availability and uptake. , Also, a high pH may cause precipitation of carbonates of Ca 2+ , Mg 2+ , and other cations. , That CaCO 3 precipitation took place is supported by the lower Ca concentrations in drainage water and leaves from the organic treatments, although the Ca 2+ concentrations in the given organic fertigation solution were similar to the inorganic fertigation solution (Table ). Furthermore, the availability of micronutrients in the root zone may be decreased at a soil pH >6.5, even in nutrient-rich conditions, due to tight binding with organic matter, clay, and other negatively charged particles. ,− …”

“…Previous studies have also shown that the nutrient concentrations of applied fertilizers are not the only determinant of mineral uptake in strawberry plants and fruits because soil properties such as pH, EC, NaCl, and microbial activity greatly determine nutrient uptake by plants. 6,15 Fruit Quality. In our study, we considered TSS, TA, firmness, and DM as important parameters for the eating quality of fruits.…”

“…15,16 The optimum range of soil pH for strawberry cultivation is 5.5−6.5, although apparently contradictory reports have been given by different researchers. Jett 17 showed that the optimum soil pH for production of strawberries was between 5.8 and 6.5, whereas Milosevic et al 15 suggested a slightly acidic soil pH between 4.5 and 6. However, in the latter investigation they used soil extraction with 0.01 M KCl, which results in a pH value approximately 0.9 unit lower than water extraction.…”

“…However, in the latter investigation they used soil extraction with 0.01 M KCl, which results in a pH value approximately 0.9 unit lower than water extraction . Nutrient uptake by strawberry plants is impaired below or above this pH range due to a reduced solubility and availability of most of the plant nutrients . Reduced availability of micronutrients may occur at high pH due to tight adsorption to negatively charged soil particles and soil organic matter or due to precipitation as, for example, carbonates, phosphates, or hydroxides. , Wang and Lin and Hargreaves et al suggested that composted municipal waste and manure increase soil pH and thereby reduce the concentrations of available nutrients.…”
