“…These findings are in accordance with the results found by [21] that ash deposited would increase soil pH. There was no significant difference under slash-and-burn practices in farming sites, which was in line with the findings of [22] that slash-and-burning has effects on soil pH and organic matter. Soil organic matter declines and soil tends to become alkaline from intensive slash and burn practices.…”

Slash-and-burn practices used by farmers in prior growing periods could affect soil quality, particularly topsoil properties. This study aimed to assess soil biophysical and chemical properties at different landscape levels within the watershed site. Soil samples were collected by a core method in the topsoil layer in slash-and-burn sites. Field analysis was on bulk density and porosity by the gravimetric method, while laboratory analysis was done on organic matter by the Loss on Ignitions Method and other macronutrients for crops (total nitrogen, phosphorus availability, and potassium availability) followed standard analytical methods. To see if there was a significant difference between sites, DMRT 5% was used. The results of the study showed slash-and-burn practice affects soil physical properties such that high bulk density in upstream, midstream, and downstream ranged from 1.55 g/cm 3 to 1.71 g/cm 3 , 1.55 g/cm 3 to 1.80 g/cm 3 , and 1.38 g/cm 3 to 1.79 g/cm 3 respectively. Poor porosity in upstream, midstream, and downstream ranged from 33.91% to 40.06%, 30.38% to 41.75%, and 30.91% to 46.65%, respectively. Organic matter content was low in the upstream, midstream, and downstream areas, ranging from 2.86% to 3.39%, 2.58% to 3.88%, and 2.91% to 3.88%, respectively. However, soil pH remains neutral, and nitrogen levels are low but near-optimal in the upstream and very low in the midstream and downstream. Phosphorus is extremely high upstream but very low in midstream and downstream. However, potassium remains at a low level close optimum level in the entire watershed.

“…In comparing the effect of the burning on organic matter content, there was an increase in organic matter after burning in Afugiri sample, while in the other two locations organic matter decreased through burning. The later result agreed with the findings of Ebel (2018) who reported a 25 % decrease due to burning practice. However, the increase observed in organic matter content of the burnt Afugiri sample (ABSS) may likely depend on soil moisture, soil type and nature of the burnt materials (González-Pérez et al, 2004).…”

Various challenges face the sustainability of soil ecosystem. This research was carried out to assess the impact of burning and application of cow dung on soil microbes. Soil samples were taken from three different locations: Afugiri, Lodu and Umudike. The study comprised of two experiments. The focus of the first experiment was to check the effect of slash and burn on soil pH, organic matter, microbial biomass phosphorus (MBP) and soil microbes. Result obtained showed that burning affected soil pH, organic matter and MBP and microbial population. Burning reduced the organic matter content of soil, and increased soil pH. The results of the microbial biomass showed that burning was disadvantageous to the sustainability of soil ecosystem. However, in the second experiment, cowdung and fortified cowdung amendment were applied to determine the effect of organic amendment on soil microbes. Cowdung significantly affected bacteria population and number of earthworm species. Bacterial species have more population than fungal species. The results from this study indicate that burning in agricultural land increases soil pH, but have the capacity to destroy beneficial microbes and reduce those activities carried out by them.

“…Legacy of structures retained from the previous stand (snags, litter, downed wood, small groups of live trees) provides a good seedbed to help in the prompt and healthy establishment of regeneration. Slash and burn is a common practice in the tropical forest of the world, and this practice can be considered a silvicultural treatment since the end result is a forest stand with an enriched species composition (Negreros-Castillo et al, 2003;Ebel, 2018).…”

Tropical timber regions across the world share common problems such as degradation and poor regeneration after timber harvesting. Traditional Mayan land management through slash and burn is now recognized as an effective way of renewing forest stands in multispecies tropical forests. The practice of slash and burn for forest management in Mexico has led to area regulation, which has made land value a convenient means of assessing alternative forest plans. The use of expected land value as a performance indicator shifts the manager's attention from managing a species mix to balancing financial tradeoffs between liquidation or retention of the standing biomass. Since the forest-wide residual stock is so large, land value overrides the importance of revenue from timber sales. Several forest management methods along these lines have appeared in tropical regions of Mexico over a thirty-year time span and represent a patrimonial system of forest management (PS). The gradual innovation generated by PS is described here, as well as examples of PS practices. PS methods today provide stewardship for a total of 155,814 ha in different parts of Mexico. PS performance will become evident in the long run; in the meantime, the embrace of PS by private landowners and regulatory institutions is equated with a positive, independent opinion about PS design. The Mexican experience suggests pathways for rational management of all types of forests. PS features that are worth replicating are, for instance, the inclusion of disturbance patterns as factors in decision making, as well as the use of specific silvicultural regimes for roads, woodlands, closed forests, hilltops, swamps, riparian zones, clearings and forest edges.
