Foragers and Farmers
Gregg (archaeology, Southern Ill. U.) argues that the transition from hunter-gatherer societies to settled agricultural communities in prehistoric Europe involved a wide variety of interactions for over a millennium. She considers the ecological requirements of crops and livestock, develops a computer simulation to identify an optimal farming strategy for early Neolithic populations, and models the effects that interaction with the farmers would have had on the foragers' subsistence-settlement system.

Feed the Soil
Synthetic chemical fertilizer pollutes lakes and rivers and kills soil organisms like earthworms. Fortunately, there is a better way to fertilize soil without polluting the environment. Feed the Soil is a book that teaches you about soil and how to improve soil fertility through natural methods. It is a reference book describing 127 different green manure crops. Growers can add nitrogen to the soil naturally by growing legumes, like peas, beans, clover or alfalfa. By growing legumes and turning them under, we can add nitrogen to the soil and improve soil fertility. This process is called green manuring and was used by the ancient Chinese and the Romans. Green manuring also adds vital organic matter to the soil. Organic matter acts like little sponges that absorb water and stores it for plant roots during dry periods. Growing legumes as green manure helps to improve and build topsoil. It is a sustainable way to farm or garden. It’s like putting money into the bank.
