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... -
Integrated influence of soil tillage, nitrogen–potassium fertiliser and mulching on pineapple (Ananas comosus (L.) Merr.) growth and yield
