Traditional soil and land appraisal on fadama lands in northeast Nigeria

Autor: P. Bullock, A. M. Kundiri, M. G. Jarvis

Publikováno v: Soil Use and Management. 13:205-208

As part of a study of recession farming on the ‘fadama’ lands on a segment of the Komadugu-Yobe floodplain, a survey was carried out to investigate the local farmers’ perception of soil types and management practices. The farmers are clearly aw

Use of Soil Maps to Predict the Incidence of Corrosion and the Need for Iron Mains Renewal

Autor: M. G. Jarvis, M. R. Hedges

Publikováno v: Water and Environment Journal. 8:68-75

The requirement for revised asset management plans from water-supply companies and the need to prioritize the renewal of buried water-supply pipework has stimulated an interest in the spatial distribution of corrosion risk and intensity. This paper r

A study of mole drainage with simplified cultivation for autumn-sown crops on a clay soil

Autor: M. G. Jarvis, Michael J. Goss, G. L. Harris, K. R. Howse, J.T. Douglas, R. Q. Cannell, S. Le Grice

Publikováno v: The Journal of Agricultural Science. 102:539-559

SummaryA replicated, long-term field drainage experiment on a clay soil was started in 1978 to investigate the effects of mole drainage on land that had been direct-drilled or ploughed. We here describe the background and the need for this work, deta

Allelic variation of glutenin subunits and gliadins and its effect on breadmaking quality in wheat: Analysis of F5 progeny from Chinese Spring × Chinese Spring (Hope 1A)

Autor: M. G. Jarvis, J.A. Seekings, P.I. Payne, L.M. Holt, A.J. Worland

Publikováno v: Journal of Cereal Science. 6:103-118

A cross was made between Chinese Spring (CS) and a genotype very similar to CS except that its I A chromosomes had been replaced by homologous chromosomes from the variety Hope. The two parents were analysed by two different two-dimensional electroph

The significance of gley features in soils derived from grey parent materials

Autor: M. G. Jarvis, A. J. Moffat

Publikováno v: Journal of Soil Science. 39:177-189

SUMMARY Detailed observations of gley features in soils derived from grey Upper Greensand rocks have been compared with their moisture regimes as determined by water-levels in dipwells. There was good correlation between the incidence of grey ped fac

VARIABILITY IN THREE AREAS OF THE DENCHWORTH SOIL MAP UNIT

Autor: C. L. Bascomb, M. G. Jarvis

Publikováno v: Journal of Soil Science. 27:420-437

Summary This paper shows correlations between soil properties and uses multivariate techniques to investigate similarities between profiles in relation to substrata. It compares laboratory measurements and field observations as means of characterizin

Structure of a silty soil in relation to management

Autor: M. G. Jarvis, K. R. Howse, Michael J. Goss, J.T. Douglas

Publikováno v: Journal of Soil Science. 37:137-151

SUMMARY In the United Kingdom silty soils have been classified as unsuitable for direct drilling since these soils may produce seed-beds that are inadequate for satisfactory crop emergence. This judgement was based on problems encountered in the firs

THE RELATION BETWEEN COST AND UTILITY IN SOIL SURVEY (I-III)1

Autor: M. G. Jarvis, P. H. T. Beckett, P. A. Burrough

Publikováno v: Journal of Soil Science. 22:359-394

Summary A series of five papers compares the cost-effectiveness of different procedures for soil survey at medium scale. The first three are presented here. The whole trial area of 120 km2 in Berkshire, in south-central England, was mapped in soil se

A novel wheat alpha-amylase gene (alpha-Amy3)

Autor: D C, Baulcombe, A K, Huttly, R A, Martienssen, R F, Barker, M G, Jarvis

Publikováno v: Moleculargeneral genetics : MGG. 209(1)

A genomic clone of a wheat alpha-amylase gene (lambdaAmy3/33) was identified, on the basis of hybridisation properties, as different from alpha-Amy1 and alpha-Amy2 genes which had been characterised previously. The nucleotide sequence revealed that t
