state of haymaking technology--a review

ABSTRACT The main objectives of research and development In haymaking are to minimize dependence on weather and to reduce loss of nutrients. Treatment of a cut crop, especially by mechanical conditioning, shortens drying time substantially while the use of chemical desiccants before or after cutting may also increase the drying rate. The advantages of terminating field exposure before drying has been completed are particularly important. Barn drying from about 40% moisture content (m.c.) wet basis has given good results. A useful alternative might be the application of preservatives to hay of high moisture content. The suppression of harmful spores, whether through barn drying or preservative treatment, lessens the risks to human and animal health.
