Within agriculture, over two-thirds of fixed capital investments in 2011 went to crop production and were concentrated in the northern wheat region (Figure 1.9 and Annex Table 1.A.3). However, the annual rate of renewal of tractors is now 1%, 2.2% for harvesters, and 0.1% for tillage tools, which is far below the normal replacement rate for agricultural machinery of 5-8%. It should be noted that, for example in the northern region old machinery is being replaced by far more productive ones, which allows less machinery to be used on same land. Smaller machines are being replaced by larger ones which are better suited to the vast areas of the northern wheat region, and the old machinery is being moved from the north to the south.
