Plant species richness in agroforestry systems correlates to soil fertility in the humid tropic of Mexico
Given the importance of agroforestry systems (AFS) in mitigating the impact of agriculture on the ecosystems and environment, it is critical to understand the effect of plant species richness in diverse tropical AFS on their soil properties. The objective of this study was to evaluate the role of different AFS in the conservation of plant species richness, and their effect on soil physical and chemical properties. We compared plant species richness and soil properties among six AFS by sampling 63 plots in the humid tropics. Sampled AFS include: (1) home garden (HG), (2) shade trees in plantation (ShTP), (3) live fences (LF), (4) scattered trees in paddocks (ScTP), (5) grazing under plantation (GP), and (6) slash and burn agriculture (SBA). The vegetation community in each plot was recorded by scientific name and species richness was calculated. Soil samples were collected from 0 to 10 and 10 to 20 cm depth and analyzed for pH, organic matter (OM), nitrogen (N), phosphorus (P), electrical conductivity (EC), cation exchange capacity (CEC), and texture. The highest plant species richness was found in HG (125), ShTP (121), and ScTP (89), followed by GP (56), LF (35), and SBA (4). This richness of plant species influenced the soil N (r = 0.514, P = 0.028), P (r = 0.480, P = 0.514), and OM contents (r = 0.439, P = 0.067), as well as CEC (r = 0.402, P = 0.097), EC (r = 0.153, P = 0.543), and pH (r = 0.363, P = 0.115). The highest values of pH (6.6) and P (8.14 mg kg−1) were observed in the species richest AFS, and the highest OM (10.8%), N (0.49%), and EC (0.26 µs/cm) were found in the SBA system that has been converted recently from forests. In the SBA, the high values of pH, OM, N, EC, and CEC were result of cutting and burning of plant biomass during the land-clearing process. It is concluded that AFS harbor a great diversity of plant species and can improve soil fertility, which is essential for developing sustainable agroecosystems. Further research is required to understand the effect of variation in AFS age on the overall soil health indicators.
期刊介绍：
Agroforestry Systems is an international scientific journal that publishes results of novel, high impact original research, critical reviews and short communications on any aspect of agroforestry. The journal particularly encourages contributions that demonstrate the role of agroforestry in providing commodity as well non-commodity benefits such as ecosystem services. Papers dealing with both biophysical and socioeconomic aspects are welcome. These include results of investigations of a fundamental or applied nature dealing with integrated systems involving trees and crops and/or livestock. Manuscripts that are purely descriptive in nature or confirmatory in nature of well-established findings, and with limited international scope are discouraged. To be acceptable for publication, the information presented must be relevant to a context wider than the specific location where the study was undertaken, and provide new insight or make a significant contribution to the agroforestry knowledge base
