The economics of soil structural degradation under cropping: some empirical estimates from New Zealand

Abstract

Soil structural degradation is a problem of some arable farms in New Zealand. This paper presents economic estimates of the significance of the loss of soil structure to farmers and the Manawatu region of New Zealand. Contingent valuation surveys of farmers and the wider community were used to estimate both use and non-use values. The results show the significance of compaction on both farm profits and land values, together with the lack of knowledge of the wider community concerning this problem. They reinforce the importance of careful farm practice, further scientific research, and a considered public policy response.
