“…await loading systems in the RSA include the current low level of operator skills (Warkotsch, 1988) and the potential for detrimental site impacts (Warkotsch, 1988;Donald, 1977;Schonau, 1977).…”

SYNOPSISCompany crew harvesting operations on Mondi Paper Company Ltd land in the highveld region, Transvaal, RSA, were studied from June to September 1990. Time studies were conducted to estimate production rates on the three operational phases: felling, skidding, and stacking. Production and cost estimates were used with the Auburn Harvesting Analyzer to simulate a harvesting system similar to the system observed in the RSA. Similar analyses were conducted for mechanised systems similar to those used in the south-eastern USA (SEUSA) to evaluate the potential for such systems in stands common to the RSA.Tree-length systems common to the SEUSA appear to have the potential to operate in the RSA at costs of up to 14 % less per cubic metre than current RSA systems. Such a system could be less sensitive to increases in labor wages since it is 140 % more productive per man hour. Wages for the SEUSA-style mechanised system could be 115 % higher than current wages and still produce wood at a cost competitive with the current RSA system. The sensitivity of this proposed mechanised system and the current RSA system to a variety of factors is examined and discussed.

“…Minor nutrients can cause deficiences in specific areas, for example boron and copper in New Zealand , boron in Tanzania (Procter 1967), copper both in Holland (Oldenkamp Smilde 1966) and in France (Bonneau 1972) and manganese in South Africa (Donald 1977). Fortunately most of these deficiencies can be corrected by the application of relatively low rates of element per hectare.…”
