The use of essential oils from certain herbal plants offers a promising alternative to synthetic insecticides for controlling the maize weevil, Sitophilus zeamais Motschulsky (Coleoptera: Dryophthoridae), major pest that causes significant damage stored grains. Essential oils, particularly aromatic herbs in Apiaceae family, are widely used medicinal, cosmetic, and food industries provided insecticidal properties mitigate environmental health hazards associated with insecticides. This...
Soil capacity as a major carbon (C) sink is influenced by land use. Estimates of soil organic (SOC) sequestration have mostly focused on topsoils [0–30 cm official Intergovernmental Panel Climate Change (IPCC) depth]. We investigated SOC stocks and their quality land-use changes. samples were collected from five depths down to 100 three adjacent fields each representing different use—forest, cassava, rice paddy—in Northeast Thailand. Sequestration in under all uses was higher, indicated...
Abstract. Maintaining soil organic matter (SOM) is crucial for healthy and productive agricultural soils requires understanding at the process level, including role of SOM protection by aggregates connection between microbial growth aggregate formation. We developed Soil Aggregation through Microbial Mediation (SAMM) model, to represent this important connection. The pools SAMM are fully measurable, we calibrated evaluated it against data from a long-term bare fallow experiment in tropical...
The objectives of this study were to investigate effects land use on accumulation soil organic matter (SOM) in the profile (0–100 cm) and determine pattern SOM stock distribution profiles. Soil samples collected from five depths at 20 cm intervals 0 100 under four adjacent uses including forest, cassava, sugarcane, paddy lands located six districts Maha Sarakham province Northeast Thailand. When considering among different all locations, forest soils had significantly higher total stocks...
Abstract Against the background of current understanding dissolved organic carbon (DOC) adsorption onto clay surfaces, it remains unclear if bulk DOC or its fractions contribute to microaggregate formation in top layers coarse‐textured soils. We therefore investigated effects long‐term inputs biochemically contrasting residues on chemical characteristics and vertical distribution a Ultisol. During 2007–2008, samples were extracted from soil profiles residue quality field experiment initiated...
Abstract. In light of the large role that soil organic matter (SOM) plays in maintaining healthy and productive agricultural soils, it is crucial to understand processes SOM protection including aggregate protection. Yet, few numerical process models include formation even fewer represent important connection between microbial growth formation. Here, we propose a model Soil Aggregation through Microbial Mediation (SAMM), which consist measurable pools 5 couples growth. The was evaluated...
The influence of the quantities and ratios dissolved organic carbon (DOC) nitrogen (DN) generated by different chemical quality classes residues on soil microbial processes in decomposition process is not well understood. If DOC-to-DN ratio (hereafter, ratio) substrate close to that C-to-N ratio, then DOC-and-DN stoichiometry balanced, resulting enhanced processing, i.e., use efficiency (CUE). Uncertainty exists about DN CUE, particularly high-quality class (high nitrogen) residue-treated...
Cassava is extensively cultivated in low fertility sandy soils the Northeast Thailand. Low yield and economic return of cassava grown this area partly due to deficiency micronutrients especially zinc (Zn). The objective study was investigate effects foliar spray Zn on growth, yield, quality variety Kasetsart 50. Five treatments consisted unfertilized control (T1), recommended fertilizer (formula 15-15-15 at rate 313 kg ha-1) (T2), plus 6.25 ha-1 (2% Zn) (T3), 12.50 (4% (T4) 18.75 (6% (T5)....
<p>It is crucial to understand what influences the dynamics of soil aggregates, because organic matter (SOM) stabilized inside aggregates fraction SOM that most susceptible anthropogenic activity. Yet, there a lack numerical process models include aggregate formation and breakdown date, no model represents important connection between microbial carbon use efficiency (CUE) formation. Here, we introduce microbially mediated formation, which includes litter-stoichiometry -quality...
