New Zealanders treat soil like dirt
An international soil scientist claims that, too often, New Zealanders treat “soil like dirt” when it should be revered because “our lives depend on it.” Dr John Baker says human life exists because of soil yet all that most people do is walk on it, dirty their shoes or dig it up and put buildings and roads on it. “Soil is a living entity. It provides us with up to 90 percent of our food. There are more living organisms in a cupful of healthy soil than people on the planet,” he says. Dr Baker says alarming figures provided by the United Nations Food and Agriculture Organisation (FAO) and the UK Farmers Weekly suggest that the quality of soil is rapidly diminishing. FAO predicts the world, on average, has just 60 more years of growing crops left while the Farmers Weekly claims that only 100 harvests remain in the UK. Dr Baker says New Zealand’s rotation of arable crops and pasture land gives us more time but many arable farmers both here and around the world are still unknowingly but progressively destroying the soils. “Eventually crop yields will decline to the point where the world’s ability to feed its ever-increasing population will be compromised,” he says. “Crunch point is expected to be about 2050 by which time there’ll be famine in some developing countries.” Dr Baker’s comments are in line with the US Senate, the FAO and he’s twice been nominated for the World Food Prize. However when he took his case to parliament’s Primary Production Committee this year, he was told it didn’t relate to any items of business currently being considered by the committee. He says because soil isn’t sexy, is not on our radar and is metaphorically beneath us, it’s taken for granted by many farmers […]
