To evaluate the influence of Phosphorus and Magnesium on the plant abundance and species richness we used a Pearson correlation Zar, Although the amount of organic matter was not analyzed in the present study, the amount of nitrogen between the two treatments did not differ statistically.
A economia da natureza. Centres of plant diversity: In spite of M. Patterns of abundance of a narrow endemic species in a tropical and infertile montane habitat. Indeed, Tilman found a negative correlation between species richness and soil fertilization while Negreiros et al. Fertilization can enhance the growth rate of plants during restoration processes, but can also promote nrb exclusion of some species Lawrence, Services on Demand Journal.
Ultimately, better nutrient 113030 would enhance plant growth and performance, hence leading to faster and larger vegetation cover.
