The purpose of this study was to determine the amounts of nutrient elements taken up from the soil to the roots, stems and leaves, in five different growing periods and to the fruits in the harvesting period, in two different strawberry cultivars. For this purpose, ten plantations were selected for each cultivar. The roots, stems and leaves were separated and the amounts of nutrient elements taken up by each part was determined according to the development period. In this study, which was conducted over two years, the physico-chemical characteristics of the soils of the plantations from which the samples taken were determined. In both cultivars, the largest amounts of the macronutrients nitrogen, phosphorus, calcium and magnesium and of the micronutrient manganese were taken up at all phenological stages by the leaves, followed by the roots and stems. The amounts of potassium that taken up were as follows in the order of most to least: at the beginning and in the harvest period, leaves, stems and roots; in other periods, leaves, roots and stems. For the nutrient elements iron, copper and zinc, this comparison showed variation between parts of the plants according to year, variety and period. In general, statistically significant correlations were found between the nutrient elements taken up at different periods by different parts of the plant of different varieties in both years. Significant differences were shown among the years in the amounts of N, P, K, Ca and Mg taken up by the fruits of the Camarosa variety, and of Fe only by the Festival variety.

Physico-chemical characterisation and fertility rating of surface soils (0-15 cm) was studied in 130 representative samples of different locations from maize growing areas from hilly zone of Shivamoga district of Karnataka.The soils were sandy loam to sandy clay loam in texture with bulk density varying from 1.43 to 1.49 Mg m-3. The study revealed that the majority of the soils were medium to highly acidic with non-saline nature and high in organic carbon status. The available nitrogen, phosphorus and potassium were low in fertility status. The exchangeable calcium and magnesium contents were marginal to adequate and varied from 2.10 to 6.90 cmol (p+) kg-1 and 0.50 to 3.30 cmol (p+) kg-1, respectively. The available sulphur ranged from 6.25 to 24.86 ppm. The soils were comparatively low to high in iron and manganese contents and were low in copper,zinc and boron contents. Hence, the nutrient management of maize growing soils plays an important role in maintaining the soil fertility and high productivity in hilly zone of Karnataka.

Water erosion causes soil degradation, which is closely related to nutrient losses either in, the soluble form or adsorbed to soil particles, depending mainly on the adopted soil management system. This study was carried out in São José do Cerrito, SC, Brazil, between March 2000 and June 2001. The objective was to quantify available nitrogen, phosphorus, potassium, calcium and magnesium losses in water erosion obtained with simulated rainfall in the following soil management systems: conventional tillage with no-crop (bare soil) (BS), conventional tillage with soybean (CT), reduced tillage with soybean (RT), no tillage with soybean on a desiccated and burned natural pasture (DBNP), and no tillage with soybean on a desiccated natural pasture (DNP). A rotating boom rainfall simulator was used to perform three rainfall tests with constant intensity of 64 mm h-1 and sufficient duration to reach constant runoff rate, on a clayey-loam, well-structured Typic Hapludox, with an average slope of 0.18 m m-1. The first test was carried out five days before soybean emergence and the second and third at 30 and 60 days, respectively. The nutrient concentration in water and total losses of nitrogen, phosphorus, potassium, calcium and magnesium were higher under CT than in the other soil management systems.

The objective of this work was to assess the relationship between macrofauna, mineralogy and exchangeable calcium and magnesium in Cerrado Oxisols under pasture. Twelve collection points were chosen in the Distrito Federal and in Formosa municipality, Goiás state, Brazil, representing four soil groups with varied levels of calcium + magnesium and kaolinite/(kaolinite + gibbsite) ratios. Soil macrofauna was collected in triplicate at each collection point, and identified at the level of taxonomic groups. Macrofauna density showed correlation with contents of kaolinite, gibbsite and exchangeable Ca + Mg in the soils. Mineralogy and exchangeable Ca + Mg had significant effects on taxonomic groups and relative density of soil macrofauna. The termites (Isoptera) were more abundant in soils with low exchangeable Ca + Mg; earthworms (Oligochaeta), in soils with high levels of kaolinite; and Hemiptera and Coleoptera larvae were more abundant in gibbsitic soils with higher contents of total carbon.
