Última Spatial and temporal effects of direct drilling on soil structure in the seedling environment Organic Eprints Munkholm, L.J.; Schjønning, P.; Rasmussen, K.J.; Tanderup, K.. Despite more than 30 years of research and practical experience the interest in shallow tillage and especially direct drilling has remained low in Scandinavia. Excessive compaction of the topsoil layer is one of the major problems encountered when adapting shallow tillage and direct drilling in particular. The purpose of this study was to evaluate temporal and spatial effects of two different direct drilling techniques on bulk density and penetration resistance in the near seed environment. A sandy loam growing small grain cereals was followed during the first 3 years after conversion from conventional tillage to direct drilling to reveal short-term changes in soil structure. A field experiment with four blocks was conducted in 1999–2001 where a... Tipo: Journal paper Palavras-chave: Soil quality Production systems Soil tillage Cereals; Pulses and oilseeds.
