The demanding situations dealing with grassland agronomists have gotten more and more advanced, with environmental and moral concerns assuming a better value along extra traditional technical elements. This new multiplied variation, with an elevated emphasis on structures pondering, has been revised to mirror present matters, wisdom and perform. As such it addresses the necessity for a unique method of grassland agronomy, offering novel and provocative fabric to tutor, stimulate and enthuse the reader.

Example text

The build up of acidity is a stress on the system that has the potential to change the system irrevocably, so that former levels of productivity either cannot be regained or cost more than is economic to do so. Good legume growth, enhanced by superphoshate application, leads to more nitrogen in the system and more chance of leaching. The lower acidity restricts legume growth, interferes with nitrogen ¢xation, and in some ways `fouls its own nest'. This example illustrates the need for trade-o¡s in our designs for grassland systems.

This made it possible to plough out more of the perennial native pasture. ã). Farmers began to collect seed and sow this plant. Strains or varieties became recognized. This legume became the focus of research attention and many limitations to its widespread use were removed by what were, at the time, exciting and innovative research programmes (Chapter å).
