In almost all cases more than one pole is used. So thick layers of oxidized peat could be indicators of old prehistoric fields.

Figure on the right: However, the relationship between crop-livestock interactions and human population density in the study of Baltenweck and others is linear and not quadratic , thus rejecting the McIntere hypothesis Baltenweck et al. Stock pits are much smaller and are just big enough to contain a pot. Those layers are for example found on the island of Tholen Stichting voor Bodemkartering The seeds were probably sown into rows of furrows made with an ard cf. The botanical macroremains point also to the winter period as the time of the accumulation of the manure layer.

In this hole a sleeper was put. The ditches are, however, no evidence for agriculture.

Intensification is thus a relative term. The digestibility of grasses strongly decreased, because of the decreasing percentage of protein and the increasing percentage of cellulose.

Mainly their seeds, silicles and capsule fragments are found in the manure layers. Another fossil marine landscape became into existence around the Broekpolder by the start of the first century at the latest, and possibly a century earlier due to the closure of the Oer-IJ estuary Therkorn et al. Composing your bibliography in tiny steps can produce a qestmaas task seem less scary. Prior to interpreting the data from assemblages of domestic bones and the analyses of farm-houses, more insight in the subject of stock composition must be acquired.

Probably the layers were the result of regular burning of the salt marshes in the late winter to achieve better grazing grounds. The excavation in Velsen showed relatively small fields, which were situated on the low dune heads.

The secondary branches were cut back to make short pegs for suspending the twigs. Simon wesstmaas Rikelike, a large landowner in the surrounding of Bruges at the beginning of the 14th century, had only 4 cart- loads of hay for 30 cows, 7 oxen, 3 heifers17, 5 calves and 13 westmzas De Destmaas Farmers in Greece suggest that the ideal cutting cycle is of three to four or perhaps five years duration for both Quercus sp.

Cattle were probably also an important product in the lowlands. Suitability for agriculture The light sandy soil on top of the gully and creek ridges were easy to till. And that will save them from wesfmaas of liver fluke. Camelina sativa seeds are also rare in the manure layers in Voorne-Putten. In the hearth samples not even one carbonized seed of Brassica rapa has been found. Clusters of spade marks and pits with Sphagnum were recognized.

In some of the buildings of the settlement thick layers of stable manure were found. This corresponds with their absence in other pre-Roman sites. Vegetation In the dunes physical soil conditions, particularly packing of the sand grains, would be the primary limiting factor for plant growth. The number of workers engaged in the hay making process is seldom mentioned by Hemmema. It was found that in the carbonized stems the characteristic cell structure of the epidermis was not visible, making differentiation impossible.

This sample is very interesting and will therefore be discussed in detail. The farms floor continued sinking into the cracks of the peat and had to be raised each time.

However, the disadvantages are obvious; the risk of tidal inundation that can destroy an entire crop Van Zeist et al.
