Soil Acidity & pH Management

Soil Acidity – Crop Yield Impacts and Management in Central West NSW

Helen McMillan and John Small Central West Farming Systems GRDC Project: CWF00019 Soil acidity and pH management for central west farming districts. Key Words: pH, acidification, lime, legumes Take home messages Soil acidification is a natural process accelerated by high crop yields and fertilizer use. It is an unseen cost of doing business. To maintain a good soil pH profile, producers...

The Chemical and Structural Benefits of Lime on Soil

The application of lime provides both vital chemical and structural benefits to soil. Their role is pivotal in combating acidity and dispersion issues associated with soil. The addition of lime in the form of calcium carbonate acts to consume hydrogen ions contributing to acidity as well as removing thick cation layers around clay particles ensuring structural stability of the soil....

The Economic Benefits of Lime

The Economic Benefits of Lime Author: Michael Quin 12/8/2015 The benefits of lime prove to be not only economically significant but the consequence of improved soil quality and increased nutrient uptake makes cropping more sustainable. However, a liming scheme does not result in overnight success. The amelioration of acidified soils is a lengthy process but it is worthwhile in the...

2015 Soil Acidity and pH Management for Central West Farming Districts

2015 sampling for the CWFS, GRDC funded, soil acidity project is now complete. To provide a brief overview of the outcomes: As shown in Table 1, five out of seven sites sampled in the year 2000, as part of a previous soil acidity project, demonstrate an increase in acidification. Out of 17 “new” sites sampled, 13 have recorded a pH (CaCl)...

Lime and Youth Champion

Soil acidity has a devastating impact on the soil profile and the soil’s role in plant production. Effects of soil acidity severely hinder the normal growth and development of plants. This is due to the decreased availability of nutrients when acidification occurs. The pH of the soil becomes lower when common farming practices are continuously applied which include: herbicide and...

LIME IT OR LOSE IT!

Soil acidity and pH management for Central West districts LIME IT OR LOSE IT! Over the past 2 decades a number of initiatives have identified soil acidity as a serious issue within the Central West of NSW. In early 2000; CWFS, GRDC, NSW Agriculture and the NSW State Government, via the Acid Soil Action program, identified that 57% of the...
