Die invloed van nat grondtoestande op die vrugkwaliteit van appels
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: A.F. Lourens --- ,Vrugontledings op appels van bome op gedeeltelik versuipte gronde gedurende die vruggroei-periode het hoër Na- en B- en laer N- en Mg-peile getoon as appels van bome op droër gronde. Die vrugte van nat persele was fermer en het hoër... -
The effect of ridging on the soil water status of a waterlogged vineyard soil
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: P.A. Myburgh --- , Republic of South Africa J.H. Moolman --- Department of Soil and Agricultural Water Science, Republic of South AfricaIn a field trial conducted in a vineyard on a low-lying hydromorphic soil, it was established that ridging increased the depth from the soil surface to the water table. Ridging did not lower the level of the water table, but... -
Ridging—a soil preparation practice to improve aeration of vineyard soils
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: P.A. Myburgh --- , Republic of South Africa J.H. Moolman --- Department of Soil and Agricultural Water Science, Republic of South AfricaWaterlogged soil conditions during early spring can result in poor grapevine performance. In this study the effect of ridging as a method of soil preparation on the depth to the water table, soil air composition and vine reaction, as indicated... -
Effect of ridging on the temperature regime of a waterlogged vineyard soil
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: P.A. Myburgh --- , Republic of South Africa J.H. Moolman --- Department of Soil and Agricultural Water Science, Republic of South AfricaWaterlogged conditions in hydromorphic soils during spring cause low temperatures which may restrict grapevine performance. Ridging is a soil preparation method that can improve internal drainage in the root zone. Temperature measurements showed that ridging tended to increase temperatures in... -
Variability among barley landraces in response to waterlogging stress in the greenhouse
Item type: Journal Article • Journal: South African Journal of Plant and Soil • Authors: A. Assefa --- Sheno Research Center, Ethiopia M.T. Labuschagne --- Department of Plant Sciences, South AfricaBarley production, in some parts of the Ethiopian central highlands, is constrained by seasonal waterlogging. The aim of this study was to investigate differences in growth, nutrient uptake and concentration under waterlogging stress between landraces varying in tolerance. A three...
