Special Issue Information

Dear Colleagues,

Land use affects essential resources within the ecosystem. Among different ecosystem resources, soil has prime importance. Poor agricultural land management gradually destroys large agricultural land areas. It is also posing a severe threat to rural agriculture in many developing countries. The pattern of land use decides the fate of soil health (physical, chemical, and biological properties) and the accumulation of toxic pollutants. Porosity bulk density, pH, water storage, topsoil moisture, organic matter, fertility, available carbon, and nitrogen contents are interlinked with land use and the presence of agricultural pollutants in soil. Deforestation, the use of persistent agricultural pollutants containing pesticides, the overuse of inorganic fertilizer, and untreated industrial sewage water cause agricultural land deterioration. In addition, persistent organic and inorganic toxins compete with the essential nutrients which can convert agricultural lands into barren non-cultivatable areas. Less soil stability causing high erosion, salinity, sodicity, waterlogging, and natural habitat destruction are some other negative impacts of poor agricultural land management. On the other hand, the significant increase in anthropogenic activities is also destroying agricultural land stability in many ways. As these issues need deep scientific attention for a better understanding of their regulatory mechanisms for the achievement of successful reclamation, we invite researchers to contribute original research and review articles to the Special Issue on “Impacts of Agricultural Land Use on Soil Properties and Agricultural Pollutants Interaction: Potential Impacts of Chemical Use”. This Special Issue will cover all possible consequences of different land-use and remediation procedures, such as soil nutrients pool, plant nutrition, and agricultural improvements, but are not limited to these. Potential topics include, but are not limited to:

  • Soil properties interaction with agricultural pollutants under agricultural land use;
  • Agricultural land use impacts on soil microenvironment and microbial diversity;
  • Impact of agricultural land uses on irrigation water quality;
  • Effect of land use on soil spatial variability.

Keywords

  • soil erosion
  • land use
  • climate change
  • soil properties
  • land conservation
  • soil management
  • persistant agricultural pollutants

Traditional mulch material (farmyard manure) has long been used in agriculture. However, recent developments have also introduced the scientific community and farmers to advanced chemicals such as potassium polyacrylamide (KPAM), which has revolutionised the concept of the soil water-holding capacity to many compared with other materials being used. To compare the effect of different organic and inorganic soil amendment materials under water stress conditions, a two-year (2018 and 2019) field study was conducted. The main plots consisted of irrigation treatments, i.e., I0 (control irrigation), I1 (drought-induced by skipping irrigation at the 4th leaf stage), and I2 (drought-induced by skipping irrigation at the anthesis stage). The subplots included a control treatment and soil amended with different conditioners such as potassium polyacrylamide (KPAM, 30 kg/ha), farmyard manure (FYM, 4 tons/ha), and biochar (10 tons/ha); these were mixed thoroughly with the soil before sowing. The results showed a significant reduction in the water relation parameters (water potential up to 35.77% and relative water content up to 21%), gas exchange parameters (net CO2 assimilation rate up to 28.85%, stomatal conductance up to 43.18%, and transpiration rate up to 49.07%), and yield attributes (biological yield up to 8.45% and grain yield up to 32.22%) under drought stress conditions. In addition, water stress also induced an increase in the synthesis of osmoprotectants (proline up to 77.74%, total soluble sugars up to 27.43%, and total free amino acids up to 11.73%). Among all the soil conditioners used, KPAM significantly reduced the negative effects of drought stress on the wheat plants. Thus, it could be concluded that the use of soil conditioners is a promising method for dealing with the negative consequences of drought stress for achieving sustainable crop yields. Full article

A detailed field experiment was carried out to study the effect of conventional and zero tillage and legume intercrops on soil health indicators and cotton productivity and also yield components of leguminous crops at the Research Farm, MNS-University of Agriculture, Multan, Pakistan. The field experiment was comprised of four legume intercrops (no intercrops (sole cotton), mung bean, mash bean, and soybean) and two tillage systems (three years zero tillage (ZT) and long-term conventional tillage (CT)). The CT showed the highest plant height (121 cm), total bolls per plant (22.9 bolls), boll weight (2.74 g) and seed yield (2031 kg ha−1) of the cotton crop, as compared to ZT. The highest leaf transpiration rate (9.28 mmol H2O m−2 s−1), net leaf photosynthetic rate (27.17 µmol m−2 s−1), stomatal conductance (0.493 mmol m−2 s−1), chlorophyll content (62.3 SPAD value), plant height (123 cm), total bolls per plant (24.4), boll weight (2.83 g), and seed yield (2090 kg ha−1) of cotton crop were recorded when it was grown as a sole crop, as compared to legume intercrops. However, soil organic matter (0.77%), phosphorus (8.08 mg kg−1), potassium (253 mg kg−1), and microbial population (7.26 × 106 Cfu) were higher in ZT than in CT. Mung bean showed a maximum number of pods (32), seed yield (173 kg ha−1), biomass (950 kg ha−1), and harvest index (19.0%), when intercropped with cotton. The highest land equivalent ratio and area time equivalent ratio were recorded in mung bean and cotton intercropping, grown under a CT system. Furthermore, the maximum benefit-cost ratio was recorded in mung bean and cotton intercropping, over sole cotton cropping under CT (1.75) and ZT (1.67) systems. The ZT and intercropping of leguminous crops with cotton might be a promising option for increasing the seed cotton yield, seed yield of leguminous crops, system profitability, and sustainability of soil health.

Different soil amendments are applied to improve soil properties and to achieve higher crop yield under drought conditions. The objective of the study was to investigate the role of biochar for the improvement of wheat (Triticum aestivum L.) growth and soil biochemical properties under drought conditions. A pot experiment with a completely randomized design was arranged with four replications in a wire house. Drought was imposed on two critical growth stages (tillering and grain filling) and biochar was applied to the soil 10 days before sowing at two different rates (28 g kg−1 and 38 g kg−1). Soil samples were collected to determine the soil properties including soil respiration and enzymatic parameters after crop harvesting. Results showed that water stress negatively affects all biochemical properties of the soil, while biochar amendments positively improved these properties. Application of biochar at 38 g kg−1 provided significantly higher mineral nutrients, Bray P (18.72%), exchangeable-K (7.44%), soil carbon (11.86%), nitrogen mineralization (16.35%), and soil respiration (6.37%) as a result of increased microbial activities in comparison with the 28 g kg−1 rate.
