Lime and Limestone in Agriculture
SHC produces a wide range of lime-based products used in agriculture. These products are most often referred to as ‘ag-lime’.
Ag-lime is generally used to increase soil pH, which can increase crop yields among a wide range of soil conditions. Ag-lime is often used to improve the physical structure of the soil by reducing surface crusting, increasing water retention, and reducing soil erosion. Lime treatment helps crops to better tolerate drought and/or wet conditions by increasing both root penetration and water percolation through the soil.
Using ag-lime to adjust pH in soils can reduce toxic levels of manganese, iron and aluminum.
- Manganese and iron exhibit toxicity to plants at a low soil pH.
- Aluminum increases in solubility as soil pH decreases. High levels of aluminum can restrict root and plant development.
In addition to the above qualities, ag-lime has been shown to increase herbicide effectiveness, increase nutrient availability to plants and add calcium to soil.
Limestone products in Dairy and Poultry
In Vietnam, dairy farmers rely on lime products to provide the foundation or a balanced pastoral production. Finely ground limestone is also used as a supplement for feeding dairy cattle and the poultry sector is supplied with carefully screened limestone chip.
