  Soil erosion by water is a problem in many fields used for grain prod uction. In order to reduce this problem, some farmers tends to avoid ploughing in the autumn, especially in the fields most exposed to ero sion. When straw and stubble cover the field surface, and the roots r einforce the soil during autumn and winter, a fairly good protection against erosion is maintained. Common seed drill systems can be unsui table on unploughed land because of straw and soil blockage in the dr ill. If the straw is cut into shorter pieces, incorporation isdone ea sier than for longer straw, and the probability of drill blockage is reduced. The cutter on the combine does not cut the remaining stubble , and the straw remaining on the surface sometimes needs more cutting . The use of a machine for cutting straw and stubble can solve this p roblem. This type of machine is used as soon as possible after the gr ain harvest. In this way, the straw material will start to decompose sooner than if uncut. Two different types of machines for straw and s tubble cutting have been evaluated. The machine must be abl e to spre ad piles of straw in order to get an even distribution of straw on th e ground.

  The results presented in this paper are from two field experiments so wn in May 1992 and June 1993. Emergence counts and sowing depth regis trations done 3 weeks after sowing. In 1992, the weather was warm and dry the first month after tillage and sowing. Factors tillage and co ulter, and interaction between tillage and coulter all gave significa nt effects on emergence. On untilled soil, only the direct drill coul ters managed to place the seeds at proper sowing depth. The highest e mergence for all coulters, was found in the plot tilled with the rota ry harrow at 50 mm working depth. The second best emergence was found in the ploughed and harrowed plot, but the difference was not signif icant. Deep harrowing gave lower emergence than the other two tillage treatments. This was evident for all conventional tillage coulters. On the untilled stubble, only the direct-drill coulters managed to pr oduce emergence. These coulters were capable of producing emergence u nder all soil conditions tested. In 1993, the weather was dry the fir st two weeks after sowing. A extra loaded, conventional coulter manag ed to place the seeds into untilled soil, and produced emergence at t he same level as the two te

  In some new drills for use in reduced- and no-tillage systems, the de sign of the coulters varies from what found on older, conventional m odels. Some of these new coulters sow two or more rows in one unit, a nd the seeds change direction one or more times inside the coulter. A n investigation has been carried out in order to find how energy of f ree falling seeds is influenced by different tube diameters, bend rad iuses and tube inclinations. The results show that the seeds loose at least 50% of their energy going through vertical tube into a 90 degr ee bend. The worst case conditions are when seeds are dropped from a vertical position into a bend with small diameter. This is due to the impact when seeds are colliding hitting the flat parts of the bend. Ideally, the tube section leading to the bend should incline some deg rees from vertical position to ensure that the seeds follow the side walls of the tube, and hence tend to avoid most of the impact in the bend section. Because of the high portion of energy loss in the bend, it is not possible to combine two or more bends in succession withou t stopping the seeds. To lower impact in the bend, the ratio between bend radius and tube diamet

  Denne rapporten er en utredning av kompetansegrunnlaget for bedre agronomi for å møte landbrukets klimautfordringer. Utredningen er gjort på oppdrag for Norges forskningsråd av Bioforsk, UMB og Høyskolen i Hedmark. Utredningen omhandler hvilke agronomiske muligheter og utfordringer jordbruket står overfor for å nå målene om lavere utslipp av klimagasser. Den tar også opp agronomiske utfordringer knyttet til effekter av endret klima og jordbrukets tilpasningsmulighter og behov for tiltak. Den gir en oversikt over hvor det er behov for målrettet FoU-innsats, og kommer med forslag til hvordan man kan sikre et godt utdanningstilbud og forskerrekruttering innen land-bruksteknikk og andre viktige områder av agronomien der studenttilgangen nå er for lav.
