Total soil K consisted of 1.7–7.1% of fixed K, which was in a positive relation to mixed-layer phyllosilicates. Differences in available K in treatments with K budget lower than –30 kg K/ha/year were small compared to those of fixed K. In control treatments, calculated average depletion of

  • The Effect of Plants on Mineral Weathering

    1998-8-1 · This paper is centered on the specific effects of plants on the soil weathering environment; we attempt to address how to quantify this component of the ecosystem and assess feedbacks between plants and weathering processes that influence the degree and rates of mineral weathering. The basic processes whereby plants directly influence the soil chemical environment is through the generation ofThe effect of land plants on weathering rates of ,A major unknown in estimating the effect of the advent of land plants on weathering rates is the nature (thickness, particle size distribution, permeability) of the regolith on the pre-Silurian continents. The indirect effect of vegetation through changing the regional distribution of precipitation may be as important as the direct effects.

At the highest dose (204 10 3 kg ha −1), olivine increased plant biomass (+15.6%) as well as K concentration in plant biomass (+16.5%). The cause of increased growth remains unclear, and may at our plant nutrient levels be unrelated to increased K uptake.Mineral sources of potassium for plant nutrition.
