RST Apology to Tasmanian Aboriginal people 2021.

A compendium of the effects of liming materials on crop, pasture and soil characteristics in Tasmania, Australia, from 1940 to 2020

Papers & Reports

Summary

Crushed agricultural limestone and dolomite are used primarily to increase soil pH (pHw) with its consequent effects on plant nutrient availability and successful introduction of Rhizobium spp. to ensure effective nodulation and nitrogen fixation by pasture and crop legumes. They have also been shown to correct calcium deficiency and, in the case of dolomite, magnesium deficiency as well. Positive effects of liming recorded in Tasmania include increasing phosphorus availability, correcting molybdenum deficiency, ameliorating toxicities of manganese and aluminium, reducing crop cadmium concentrations in root crops, reducing phosphorus leaching, improving soil structure and negating soil acidification processes. Negative effects of liming that have been reported include inducing boron deficiency and encouraging plant disease. Options for future research are canvassed.
