To take advantage of conservation tillage systems (including direct drilling and non-inversion) in central Iran, it is important to study the effects of different cultivation practices on soil structural stability as a physical indicator. A four-year study was conducted to investigate the effects of seven tillage systems on aggregate properties of a clay-loam soil (Calcic Cambisol) with continu...

Quantification of soil aggregation and erodibility from easily measurable characteristics have been done by using pedo-transfer functions (PTFs) PTFs developed were compared statistical machine learning techniques for the kandi region Punjab. Dataset 1, having six basic properties, was used estimation mean weight diameter (MWD) (K), prediction an artificial neural network (ANN) slightly better ...

Arbuscular mycorrhizas possess well developed extraradical mycelium (ERM) network that enlarge the surrounding soil for better acquisition of water and nutrients, besides soil aggregation. Distinction in ERM functioning was studied under a rootbox system, which consisted of root+hyphae and root-free hyphae compartments separated by 37-μm nylon mesh with an air gap. Trifoliate orange (Poncirus t...

Soil aggregate stability and erodibility are the influential factors governing soil resistance to water erosion. The interactions among stability, erodibility, their influencing have not been fully explored. We collected samples from 0–10 cm 10–20 layers in Zhifanggou watershed. Then, major contributors how properties, environmental land use contributed them were explored by using partial least...

To determine the effects of straw incorporation on soil nutrients, enzyme activity, and aggregates in tobacco fields, we conducted experiments with different amounts of wheat and maize straw in Zhucheng area of southeast Shandong province for three years (2010–2012). In the final year of experiment (2012), straw incorporation increased soil organic carbon (SOC) and related parameters, and impro...

Tropical regions have been considered the world's primary agricultural frontier; however, some physico-chemical deficiencies, such as low soil organic matter content, poor soil structure, high erodibility, soil acidity, and aluminum toxicity, have affected their productive capacity. Lime and gypsum are commonly used to improve soil chemical fertility, but no information exists about the long-te...

Abstract Changes in soil organic carbon (SOC) and aggregate stability as a result of agricultural practices have been extensively studied, but the extent these changes is site crop specific. In this study, SOC were evaluated under undisturbed grassland, cultivated pasture arable land uses northern KwaZulu-Natal, South Africa. The soils study sampled from 0–5, 5–10 10–20 cm depths Nitisol, Stagn...
