coarse textured soil

Catalogue: Ground Cover
Queensland University of Technology's Professor Peter Grace discusses strategies to help avoid nitrogen losses at a recent GRDC Grains Research Update... The loss is caused by chemical reactions on the surface of the soil, and only occurs in alkaline soils when ammonium-based fertiliser is broadcast and there is no rain to wash it into the soil... Rain is required to wash the fertiliser deeper into the soil profile, but not too much that it could cause denitrification or leaching...

Overall, soil CEC and SOC content was greatest in the 0.2 and 0.2-2 m fraction, indicating that size, and probably type, of SOM influenced CEC... Kaiser et al. (2003) found that soils with a high content of black carbon showed increased sorption ability compared with plant- and microbial-derived SOM... Addition of organic amendments can increase P availability to plants by decreasing the P adsorption capacity of soils...
