Is this blog dead? Again? No, here we come.
The issue is a “book” (or whatever): Soil and crop management for today and tomorrow.
My intention is to compile it directly on the net. See link in Blogroll to the right . Welcome to comment. Below is the Introduction.
We have deep knowledge in soil and crop science as well as in environmental sciences and ecology. It forms a base for advanced models on the behaviour of soils and crops, the growth processes and environmental consequences of various kinds. Contiunuous development is going on, The main problem is the variability of soil and weather parameters.
We have field experiments giving a base for recommendations to farmers.
This is transformed to actions in the fields, by advisors and farm managers. Their main task and interest is to optimize the economic result of the farming enterprise.
We also have a global and political environment listing demands or in any case environmental problems to work on:
Food production should increase
Water is scarce
Climate gases should be reduced
Nitrogen flows should be reduced.
Chemicals in general should be reduced
Agricultrual land may be needed for bioenergy
Biodiversity needs consideration.
The practical agricultrure are influenced by economic factors, various administrative measures and, not least, by the knowledge and interest of the farmer
The intention with this work is to try to summarize and discuss this complex and ways to handle it.
