Soil fertility refers to the ability of soil in a particular area provide favorable chemical, physical and biological characteristics that help plant its growth. It is affected by multiple parameters, from available concentration Nitrogen Organic Carbon soil. This paper discusses implementation an explainable AI (XAI) model based on Random Forest classifier. The developed reliably predicts rela...

The interactive effects of soil texture and type of N fertility (i.e., manure vs. commercial N fertilizer) on N(2)O and CH(4) emissions have not been well established. This study was conducted to assess the impact of soil type and N fertility on greenhouse gas fluxes (N(2)O, CH(4), and CO(2)) from the soil surface. The soils used were a sandy loam (789 g kg(-1) sand and 138 g kg(-1) clay) and a...

Microbiological activity is a general term which includes all metabolic reactions and interactions of the soil microflora and macrofauna.1 Soil microorganisms contribute to soil fertility and aggregate formation in degraded soils.2 However, it is only during the last decades that ecologists have beginning to explore the underground communities and their functional significance for the plant com...

The ability of hyperspectral image (HSI) data to provide estimates of soil electrical conductivity (ECa) and soil fertility levels without requiring extensive field data collection was investigated. The relationships between HSI spectral reflectance signatures and soil properties were analyzed to evaluate the usefulness of HSI for quantifying within -field spatial variability. Bare soil images ...

The response of whole-plant water-use efficiency, termed transpiration efficiency (TE), to variation in soil fertility was assessed in a tropical pioneer tree, Ficus insipida Willd. Measurements of stable isotope ratios (delta(13)C, delta(18)O, delta(15)N), elemental concentrations (C, N, P), plant growth, instantaneous leaf gas exchange, and whole-plant water use were used to analyse the mecha...

There is currently much interest in the interactions between exotic plants and soil organisms. Exotic invasive species can have profound effects on the microbial community of the soil and positive feedback of soil biota to invasive plants may facilitate their successful invasion. To better understand the impacts of Ambrosia artemisiifolia L. invasion on microbial carbon source utilization and r...

The aim of this study was to determine the effect of three active substances, diflufenican, mesosulfuron-methyl and iodosulfuron-methyl-sodium, applied in combination, on soil microbial counts, the structure of soil microbial communities, activity of soil enzymes and their resistance to the tested product, the biochemical indicator of soil fertility, and spring wheat yield. Soil samples with th...

Agricultural production in the Koutiala region, southern Mali, is based on cash sources (cotton and groundnut), cereal sources (maize, sorghum, millet), and a store of wealth (livestock). In these low-input farming systems, crop production is seriously constrained by soil fertility decline. Research is being conducted in the region to investigate the potential of improved fallows planted to leg...

The soil organic carbon (SOC) of the Argiudolls of the Argentine Rolling Pampa evolves rapidly. Currently, the soils richest in SOC are cultivated with intensified crop sequences (e.g. maize-double cropped wheat/soybean, MWS) under no tillage (NT) and the poorest ones with soybean monoculture (S) under NT. There are great uncertainties about the future projections of SOC reserves and soil ferti...
