(Taylor & Francis Group, 1996-03-01)Biogeochemical maps determined from the distribution of sparsely sampled cadmium have been improved by the incorporation of more densely sampled zinc with which it is correlated and by the application of cokriging. The ...
-
(Taylor & Francis Group, 1994-06-01)A crop growth model was integrated with a geographical information system (GIS) in order to quantify the impact of local temperature variation and soil water capacity on ley production. At most, local temperature differences ...
-
Comparison of Conventional, Integrated and Organic Potato Production in Field Experiments in Finland(Taylor & Francis Group, 1996-03-01)In 1987, a potato research project called “Minimized use of chemical inputs in potato production” was started in all five Scandinavian countries. In this paper, the results of one field trial series carried out at the ...
-
(Taylor & Francis Group, 1995-03-01)Several methods have been developed to assess differences in cultivar response to drought. This study consisted of 19 oat (Avena sativa L.) cultivars and breeding lines and three species of wild oats, and focused on ...
-
(Taylor & Francis Group, 1992-06-01)Several methods were tested for estimating population size of two phytophagous mites on the apple cultivars Aroma, Summerred and Gravenstein. The washing technique was rated as most efficient for estimating the Panonychus ...
-
(Taylor & Francis Group, 1995-06-01)The high-molecular-weight (HMW) glutenin subunit composition of Swedish wheat cultivars and advanced breeding lines was determined by using polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulphate. The ...
-
(Taylor & Francis Group, 1993-06-01)Food waste from a school and a restaurant was composted with topsoil only and together with topsoil, cattle manure, stock compost and sewage water in different combinations. The temperature maximum reached 46–55 °C in ...
-
(Taylor & Francis Group, 1993-12-01)Food waste, waste paper and different topsoils were composted in different experiments. The composts were characterised by high contents of N, P, S, Na and K in the food waste, of Mg in the soil, and of Ca in paper and ...
-
(Taylor & Francis Group, 1994-09-01)Food waste from a hospital was composted with waste paper, milk carton and topsoil in different combinations. The ready compost reflected the high content of N, P, K, S, Cl, Na and K in the food waste and that of Mg in the ...
-
(Taylor & Francis Group, 1995-06-01)Food waste, straw, paper and topsoil were composted in different combinations. The catching of nitrogen was more than 90% when using different amounts of straw and of a small amount of paper. It was above 50% in paper ...
-
(Taylor & Francis Group, 1994-12-01)The contents of the HNO3- and EDTA-extractable micronutrients, Co, Cu, Mn and Mo, have been determined in 53 soil samples from nine Danish Spodosols and Ultisols. In most soils the contents decreased from surface to ...
-
(Taylor & Francis Group, 1994-06-01)16 Danish mineral soils, depleted in P by cropping for 10 years, were used in a pot experiment to investigate the capacity of rye grass to recover new fertilizer P from application of 4 and 8 mg P per 100g soil. In the ...
-
(Taylor & Francis Group, 1994-03-01)Degradation and leaching of 14C-labelled simazine in coarse sandy soils at 15 + 1°C were investigated using radiometric and mass-spectrometric methods. During 6 months incubation approx. 4–7% of the applied 14C-simazine ...
-
(Taylor & Francis Group, 1995-12-01)The interaction between soil factors and denitrification loss from soil is not well understood. This study was conducted to determine whether soil air-filled porosity (AFP), nitrate concentration and N management could ...
-
(Taylor & Francis Group, 1994-12-01)An immunoassay method for analysis of trypsin and chymotrypsin inhibitor activity in seeds from different pea cultivars has been developed. This method is fast, cheap and well suited for screening of large numbers of seed ...
-
(Taylor & Francis Group, 1992-09-01)In order to supply the correct amount of ammonium to the crop when slurry is spread on the field, it is necessary to know the ammonium concentration. Slurry is a heterogeneous substance and there is a risk that organic ...
-
(Taylor & Francis Group, 1993-09-01)Development of cold tolerance in white clover (Trifolium repens L.) genotypes originating from various parts of Norway and grown outdoors at Tromso, latitude 69°39′N, has been studied. Stolon samples for an artificial ...
-
(Taylor & Francis Group, 1994-06-01)In pot experiments with greatly differing rates of N, P, K and S, two levels of Ca and three levels of water, dry matter (DM) yields of tubers varied from 35 to 402 g/pot. K-Deficiency and water stress reduced the starch ...
-
(Taylor & Francis Group, 1992-12-01)Cauliflower and lettuce seedlings were treated with different methods of mechanical stress (MS): brushing (1.5 min/day) with bond typing paper or with burlap, unidirectional fanning (5 min/day), or shaking the seedlings ...
-
(Taylor & Francis Group, 1994-12-01)The distribution of photoassimilated C in spring barley plants was determined at different times after the onset of light and at different light intensities during assimilation. The plants were grown in pots in a greenhouse, ...
